POS & Restaurant Technology
Glossary

100+ terms defined in plain language by restaurant technology experts with 30+ years of industry experience. Whether you're buying your first POS or upgrading a multi-location system, understand every term before you sign.

A B C D E F G H I K L M N O P Q R S T U V W

A

ACH (Automated Clearing House)

An electronic network for financial transactions in the United States. ACH transfers move money directly between bank accounts and are commonly used for payroll, vendor payments, and recurring billing. ACH fees are typically much lower than credit card processing fees, making them a cost-effective option for B2B transactions and large payments.

API (Application Programming Interface)

A set of protocols that allows different software systems to communicate with each other. In the POS world, APIs enable integrations with accounting software like QuickBooks, delivery platforms like DoorDash, loyalty programs, and third-party applications. A strong API ecosystem means your POS can connect to virtually any business tool you use.

Average Check Size

The mean dollar amount spent per transaction or per customer visit. Calculated by dividing total revenue by the number of transactions. This is a key performance metric for restaurants — a higher average check means more revenue per guest without needing to increase foot traffic. POS systems track this automatically and break it down by daypart, server, and menu category.

Authorization

The process of verifying that a customer's credit or debit card has sufficient funds and is valid before completing a transaction. The POS sends the card details to the payment processor, which contacts the issuing bank for approval. Authorization happens in seconds but is a distinct step from settlement, when funds actually transfer.

Auto-Gratuity

An automatic service charge added to a bill, typically for large parties (6+ guests). POS systems can be configured to add auto-gratuity at a set percentage based on party size, ensuring servers are fairly compensated for large-table service. The percentage and party-size threshold are customizable.

B

Batch Settlement

The process of sending a group of authorized credit card transactions to the payment processor for final processing and fund transfer. Most restaurants batch out at the end of each business day. Failing to batch on time can result in higher interchange rates or declined transactions on pre-authorized cards.

Barcode Scanner

A hardware device that reads UPC or QR codes to identify products at the point of sale. Barcode scanners speed up checkout, reduce manual entry errors, and automatically update inventory counts. Essential for retail POS environments and increasingly used in restaurants for packaged goods and gift cards.

Biometric Authentication

Using physical characteristics like fingerprints to verify employee identity at the POS. KwickOS supports both 1:N identification (scanning a finger to identify who it belongs to) and 1:1 verification (confirming a specific person's identity). Prevents buddy punching, time theft, and unauthorized access to sensitive functions.

Buddy Punching

When one employee clocks in or out on behalf of another, resulting in inaccurate time records and overpayment. Buddy punching costs U.S. employers an estimated $373 million annually. Biometric POS systems with fingerprint authentication eliminate this problem entirely.

C

Card-Not-Present (CNP)

A transaction where the physical card is not present at the point of sale — such as online orders, phone orders, or app-based payments. CNP transactions carry higher processing fees and fraud risk than card-present transactions because the merchant cannot verify the physical card or chip.

Cash Discount

A pricing model where customers who pay with cash receive a discount (typically 3-4%) off the listed price. This offsets the merchant's credit card processing fees. Cash discount programs must be clearly disclosed to customers and comply with card network rules. Different from surcharging, which adds a fee for card payments.

Chargeback

A forced reversal of a credit card transaction initiated by the cardholder's bank. Chargebacks can result from fraud, customer disputes, or processing errors. Each chargeback costs the merchant the transaction amount plus a fee ($20-$100). Excessive chargebacks can lead to higher processing rates or account termination.

Cloud POS

A point-of-sale system where all data processing and storage happens on remote servers accessed via the internet. Cloud POS systems are easy to set up and access from anywhere, but are completely dependent on internet connectivity. If the internet goes down, a pure cloud POS cannot process transactions.

arrow_forward Cloud vs Local POS comparison

Contactless Payment

A payment method using NFC (Near-Field Communication) technology, allowing customers to tap their card, phone, or wearable device near the terminal to pay. Contactless transactions are faster than chip insertions and became the preferred payment method for many consumers during and after the COVID-19 pandemic.

CRM (Customer Relationship Management)

Software that tracks customer interactions, purchase history, preferences, and contact information. Restaurant CRM systems built into the POS automatically build customer profiles based on order data, enabling personalized marketing, loyalty programs, and targeted promotions.

arrow_forward KwickOS CRM & Loyalty

Cross-Selling

Suggesting complementary items to a customer during the ordering process. POS systems can be configured to prompt servers or kiosk screens with cross-sell suggestions — for example, recommending a side dish when a customer orders an entree, or suggesting a dessert after the main course.

D

Dayparting

Dividing the business day into segments (breakfast, lunch, dinner, late night) for analysis and menu management. POS reporting by daypart reveals which items sell best at which times, enabling menu optimization, staffing adjustments, and targeted promotions for slower periods.

Delivery Management

The system for tracking and coordinating food delivery orders from placement through completion. Includes driver assignment, route optimization, estimated delivery times, and real-time tracking. KwickOS integrates delivery management with KwickDriver at a flat $2 fee + $6.99/5mi — far less than the 15-25% commissions charged by DoorDash or UberEats.

arrow_forward KwickOS Delivery & Maps

Digital Signage

Electronic displays used to show menus, promotions, wait times, or branding content in a restaurant or retail environment. Digital signage can be updated remotely and in real-time, allowing businesses to change pricing, add seasonal items, or run time-based promotions without printing new materials.

arrow_forward KwickSign Digital Signage

Dual Pricing

Displaying two prices for each item — a cash price and a card price — where the card price includes the cost of credit card processing. Unlike surcharging (which is restricted in some states), dual pricing is legal in all 50 states when properly disclosed. The POS automatically applies the correct price based on payment method.

E

EMV (Europay, Mastercard, Visa)

The global standard for chip-based credit and debit card transactions. EMV chips generate a unique transaction code for every purchase, making cards significantly harder to counterfeit than magnetic stripe cards. Since the 2015 liability shift, merchants who don't accept EMV chip cards are liable for counterfeit card fraud.

ERP (Enterprise Resource Planning)

An integrated software system that manages core business processes including inventory, accounting, HR, and supply chain. While traditionally associated with large corporations, modern POS systems like KwickOS incorporate many ERP functions — making enterprise-level business management accessible to small businesses.

E-Receipt (Electronic Receipt)

A digital receipt sent to customers via email or SMS instead of a printed paper receipt. E-receipts reduce paper waste, provide a channel for marketing and loyalty enrollment, and give customers a searchable record of their purchases. POS systems can prompt customers to choose between paper and electronic receipts.

End-of-Day Report (EOD)

A summary report generated at the close of business showing total sales, payment breakdowns, voids, refunds, tips, and tax collected. EOD reports are essential for daily reconciliation and are typically run when the last register closes or during the batch settlement process.

F

FIFO (First In, First Out)

An inventory management method where the oldest stock is used or sold first. Critical in food service to minimize waste and ensure freshness. POS inventory systems with FIFO tracking alert staff when items are approaching expiration and prioritize older inventory for preparation.

arrow_forward KwickOS Inventory Management

Food Cost Percentage

The ratio of food ingredient costs to food sales revenue, expressed as a percentage. Calculated as (Cost of Goods Sold / Food Revenue) x 100. Most restaurants target 28-35% food cost. POS systems with recipe costing and inventory tracking calculate this automatically and flag items that exceed target margins.

Franchise POS

A POS system designed for franchise operations, enabling centralized menu management, pricing control, and reporting across all franchise locations while allowing individual franchisees to manage day-to-day operations. KwickOS supports multi-location management with one-click menu sync across all stores.

Flat-Rate Pricing

A payment processing pricing model where the merchant pays the same percentage on every transaction regardless of card type. Simple to understand but typically more expensive than interchange-plus pricing, especially for businesses with high debit card volume. Square and Toast use flat-rate pricing.

G

Ghost Kitchen

A commercial kitchen that prepares food exclusively for delivery — with no dine-in or takeout counter. Also called virtual kitchens or cloud kitchens. Ghost kitchens rely heavily on POS systems integrated with multiple delivery platforms, online ordering, and kitchen display systems to manage high order volumes.

Gratuity (Tip)

A voluntary payment from a customer to a service employee, typically calculated as a percentage of the bill. POS systems present tip options on the payment screen (commonly 15%, 18%, 20%, or custom) and track tip distribution for payroll. Some systems support tip pooling and automatic tip-out calculations.

Gross Margin

The percentage of revenue remaining after subtracting the cost of goods sold (COGS). Calculated as ((Revenue - COGS) / Revenue) x 100. For restaurants, this reflects the profitability of menu items before labor and overhead costs. POS systems with menu engineering tools display gross margin by item, category, and time period.

Gift Card

A prepaid stored-value card issued by a business for future purchases. Gift card programs drive new customer acquisition and generate immediate cash flow. Modern POS systems manage gift card balances, track redemptions, and support both physical and digital gift cards.

arrow_forward KwickOS Gift Cards

H

Hybrid POS

A point-of-sale system that processes transactions locally on-premise while syncing data to the cloud for remote access, backup, and multi-location management. Hybrid POS combines the speed (1ms local latency vs 20ms cloud) and offline reliability of local processing with the accessibility of cloud-based management. KwickOS uses this architecture.

arrow_forward Cloud vs Local POS comparison

Handheld POS

A portable POS device — typically a tablet or purpose-built handheld terminal — that allows servers to take orders and process payments at the table. Handheld POS reduces wait times, improves order accuracy, and increases table turnover by eliminating trips to a stationary terminal.

Happy Hour Pricing

Time-based automatic price adjustments for menu items during designated promotional periods. POS systems can be programmed to apply happy hour discounts at specific times and days without staff intervention, ensuring consistent pricing and accurate reporting of promotional vs. regular sales.

I

Interchange Fee

The fee paid by the merchant's bank to the cardholder's bank every time a credit or debit card transaction is processed. Interchange fees are set by card networks (Visa, Mastercard) and vary by card type, transaction method, and merchant category. They typically range from 1.5% to 3.5% and are the largest component of payment processing costs.

Interchange-Plus Pricing

A transparent payment processing pricing model where the merchant pays the actual interchange fee plus a fixed markup from the processor. More cost-effective than flat-rate pricing for most businesses, but requires a processor-agnostic POS to take advantage of — since systems like Toast lock you into their own processing rates.

Inventory Management

The system for tracking raw materials, ingredients, and finished goods from purchase through sale. POS-integrated inventory management automatically deducts ingredients as items are sold, alerts when stock is low, tracks waste, and generates purchase orders. Essential for controlling food costs and preventing stockouts.

arrow_forward KwickOS Inventory

ISV/ISP Integration

Independent Software Vendor / Independent Sales Organization integration — connecting third-party software providers with POS platforms through APIs and partnerships. ISV integrations allow POS systems to extend functionality with specialized tools for accounting, reservations, staff management, and more.

K

KDS (Kitchen Display System)

A digital screen mounted in the kitchen that replaces paper order tickets. KDS systems display orders in real-time as they're entered at the POS, track preparation times, route items to the correct preparation stations, and alert staff to rush orders or special modifications. Reduces ticket loss and improves kitchen efficiency.

arrow_forward KDS Guide

Kiosk (Self-Ordering)

A freestanding touchscreen terminal where customers place and pay for their own orders without interacting with a cashier. Self-ordering kiosks increase average check size by 15-30% through consistent upselling prompts and reduce labor costs. KwickOS powers kiosk deployments like Rockin' Rolls Sushi Express with 49 iPad stations.

arrow_forward Self-Ordering Kiosk Guide

Kitchen Printer

A thermal or impact printer located in the kitchen that prints order tickets as they are entered at the POS. Being replaced by KDS in many operations, but still common in smaller restaurants. Impact printers (dot-matrix) are preferred in kitchens because they withstand heat and humidity better than thermal printers.

L

Labor Cost Percentage

The ratio of total labor costs (wages, benefits, taxes) to total revenue, expressed as a percentage. Most restaurants target 25-35% labor cost. POS systems track labor costs in real-time by comparing scheduled hours and wages against actual sales, helping managers make staffing decisions during the shift.

Local POS (On-Premise POS)

A point-of-sale system where data processing and storage happen on hardware located at the business premises rather than on remote cloud servers. Local POS systems offer faster transaction speeds, offline capability, and greater data control, but may require more upfront hardware investment.

arrow_forward Cloud vs Local POS comparison

Loyalty Program

A rewards system that incentivizes repeat business by offering points, discounts, or free items based on purchase history. POS-integrated loyalty programs automatically track customer spending and apply rewards at checkout without requiring separate punch cards or apps. Increases customer retention and average visit frequency.

arrow_forward KwickOS CRM & Loyalty

M

Mobile POS (mPOS)

A point-of-sale system running on a smartphone or tablet, often paired with a card reader attachment. Mobile POS systems are portable and affordable, making them ideal for food trucks, pop-up events, and tableside ordering. They typically process payments via Bluetooth-connected card readers.

Multi-Location Management

The ability to manage menus, pricing, employees, and reporting across multiple business locations from a single dashboard. Critical for restaurant groups, franchises, and chains. KwickOS supports operations from 2 locations to 600+ — like Haidilao Hot Pot — with one-click menu sync and real-time remote monitoring.

arrow_forward Multi-Location Management Guide

Modifier

An option that customizes a menu item — such as adding extra cheese, choosing a side, or specifying a cooking temperature. POS systems support required modifiers (customer must choose), optional modifiers, and nested modifiers (modifier groups within modifier groups). Proper modifier setup reduces kitchen errors and speeds up ordering.

Merchant Account

A bank account that enables a business to accept credit and debit card payments. Funds from card transactions are deposited into the merchant account before being transferred to the business's regular bank account. Processor-agnostic POS systems let merchants choose any merchant account provider.

N

NFC (Near-Field Communication)

A short-range wireless technology that enables contactless payments. NFC allows customers to pay by tapping a card, smartphone (Apple Pay, Google Pay), or wearable device within a few centimeters of the terminal. Transactions complete in under a second, making NFC the fastest in-person payment method available.

Net Margin

The percentage of revenue remaining after all expenses — including COGS, labor, rent, utilities, and taxes. Calculated as (Net Profit / Revenue) x 100. The average restaurant net margin is 3-9%. POS reporting that combines sales data with expense tracking gives operators real-time visibility into true profitability.

No-Sale

Opening the cash drawer without processing a transaction. POS systems log every no-sale event with the employee ID and timestamp, as frequent no-sales can indicate employee theft. Managers can restrict no-sale access to authorized roles through permission settings.

O

Offline Mode

The ability of a POS system to continue processing transactions when the internet connection is unavailable. Systems with offline mode store transactions locally and sync them to the cloud when connectivity is restored. KwickOS's hybrid architecture provides full offline capability — unlike cloud-only systems like Toast or Square that go down during internet outages.

Online Ordering

A system that allows customers to place orders through a website or mobile app for pickup or delivery. POS-integrated online ordering sends orders directly to the kitchen display system, eliminating manual re-entry and reducing errors. KwickMenu processes 500K+ clicks per month for KwickOS merchants.

arrow_forward KwickOS Online Ordering

Open Tab

A running order associated with a customer's credit card, typically in bar and restaurant settings. The customer's card is swiped or stored at the beginning, orders are added throughout the visit, and the tab is closed when the customer is ready to pay. POS systems track open tabs by seat, table, or customer name.

Order Throttling

Automatically limiting the number of incoming online or delivery orders to prevent the kitchen from becoming overwhelmed. When order volume exceeds kitchen capacity, the POS extends estimated wait times or temporarily pauses new orders. Prevents quality degradation during peak periods.

P

PCI Compliance (PCI DSS)

Payment Card Industry Data Security Standard — a set of security requirements that any business accepting credit card payments must follow. PCI compliance includes encrypting cardholder data, maintaining secure networks, implementing access controls, and regular security testing. Non-compliance can result in fines of $5,000-$100,000 per month.

arrow_forward KwickOS Trust & Security

Payment Processor

A company that handles the technical connection between the merchant's POS, the card networks (Visa, Mastercard), and the issuing banks. The processor routes authorization requests, handles settlement, and deposits funds into the merchant account. Processor-agnostic POS systems like KwickOS let merchants choose any processor.

POS (Point of Sale)

The system where a retail transaction is completed. Modern POS systems go far beyond simple cash registers — they combine hardware (touchscreen terminals, receipt printers, card readers, kitchen displays) with software for sales processing, inventory management, employee management, CRM, reporting, and analytics.

arrow_forward Best POS Systems for Restaurants

Prime Cost

The combined cost of goods sold (food and beverage) plus total labor cost. Prime cost is the most important profitability metric in the restaurant industry, typically targeting 55-65% of total revenue. POS systems that integrate sales, inventory, and labor data can calculate prime cost in real-time.

Processor-Agnostic

A POS system that works with any payment processor rather than locking merchants into a proprietary processing service. Processor-agnostic systems let merchants negotiate their own rates, switch processors without switching POS systems, and keep 100% of their processing revenue. KwickOS is processor-agnostic; Toast, Square, and Clover are not.

Prep List

A daily list of ingredients and items that need to be prepared before service based on expected demand. POS systems with forecasting capabilities can auto-generate prep lists based on historical sales data, day of week, and upcoming events or reservations.

Q

QR Code Ordering

A contactless ordering method where customers scan a QR code with their smartphone to access a digital menu and place orders directly from their table. Orders flow into the POS and kitchen display system automatically. Reduces wait times for servers, increases order accuracy, and lowers labor requirements.

QSR (Quick Service Restaurant)

A restaurant category focused on fast food service with limited or no table service — such as fast food chains, counter-service restaurants, and food courts. QSR POS systems prioritize speed, self-ordering kiosks, and drive-through integration over features like table management and coursing.

R

Receipt Printer

A thermal or impact printer that produces customer receipts at the point of sale. Thermal printers are faster and quieter but receipts fade over time. Impact printers are durable and heat-resistant, making them better for kitchen environments. Many businesses are transitioning to e-receipts to reduce paper waste and costs.

Recurring Revenue

Income that a business or reseller can expect to receive on a regular, ongoing basis. In the POS industry, recurring revenue comes from monthly software subscriptions, payment processing residuals, and ongoing service fees. KwickOS partners earn recurring processing residuals for the lifetime of each merchant they bring on.

arrow_forward KwickOS Partner Program

Residual Income

Passive income earned from payment processing volume on an ongoing basis. When a POS reseller or ISO places a merchant, they earn a small percentage (basis points) of every transaction that merchant processes — for as long as that merchant remains active. This creates a compounding revenue stream.

RevPASH (Revenue Per Available Seat Hour)

A restaurant performance metric that measures revenue generated per seat per hour of operation. Calculated as Total Revenue / (Number of Seats x Hours Open). RevPASH helps identify underperforming dayparts and optimize table turnover, seating layout, and reservation scheduling.

Role-Based Access Control (RBAC)

A security model that restricts POS functions based on the user's role — cashier, server, manager, owner. RBAC ensures that only authorized personnel can perform sensitive operations like processing refunds, modifying prices, viewing reports, or accessing employee records.

S

SaaS POS (Software as a Service)

A POS system delivered as a cloud-based subscription service rather than a one-time software purchase. SaaS POS systems charge monthly fees, handle updates automatically, and can be accessed from any internet-connected device. Toast, Square, and Clover all use SaaS pricing models.

Self-Ordering Kiosk

A freestanding or countertop touchscreen where customers browse the menu, customize orders, and pay without staff assistance. Studies show kiosks increase average order value by 15-30% through consistent upselling and cross-selling prompts. KwickOS powers kiosk deployments from single-unit bakeries to multi-location restaurant chains.

arrow_forward Self-Ordering Kiosk Guide

Server Banking

A cash handling method where each server is responsible for making their own change from a personal cash bank, rather than using a shared cash drawer. The POS tracks each server's sales and cash collected independently, making end-of-shift reconciliation straightforward.

Shrinkage

The loss of inventory due to theft, waste, spoilage, or administrative errors. In restaurants, shrinkage directly impacts food cost percentage and profitability. POS systems with inventory tracking can identify shrinkage by comparing expected usage (based on sales) against actual inventory counts.

Split Payment

Dividing a single bill across multiple payment methods or multiple guests. POS systems support splitting by item (each person pays for what they ordered), splitting evenly (total divided equally), or splitting by amount (custom amounts per person). A common feature request that surprisingly not all POS systems handle well.

Station Routing

Automatically directing specific menu items to the correct preparation station in the kitchen. For example, drink orders route to the bar printer/display, appetizers to the cold station, and entrees to the hot line. Proper station routing eliminates confusion and speeds up order preparation. Crafty Crab uses customized KDS station routing for special requests.

Surcharge

An additional fee added to a transaction when a customer pays with a credit card, intended to offset the merchant's processing costs. Surcharging is prohibited in several states and is regulated by card network rules — the surcharge cannot exceed the merchant's actual processing cost or 3%, whichever is lower. Different from dual pricing or cash discount programs.

T

Table Management

The system for tracking table status (open, seated, ordered, check dropped, bussing), managing reservations, and optimizing seating. POS-integrated table management gives hosts real-time floor views, estimated wait times, and automatic table assignment based on party size and server sections.

Terminal

The physical hardware device where POS software runs and transactions are processed. Terminals range from traditional countertop touchscreen units to tablets mounted on stands to handheld devices. A single restaurant may have multiple terminals — one per register, plus server stations and kitchen displays.

Tip Pooling

A compensation structure where tips from all tipped employees are combined and redistributed according to a predetermined formula. POS systems automate tip pooling calculations based on hours worked, role, or custom percentages, ensuring accurate and fair distribution while maintaining compliance with labor laws.

Token (Tokenization)

A security process that replaces sensitive payment card data with a unique, randomly generated identifier (token). The token is meaningless if intercepted — only the payment processor can map it back to the original card number. Tokenization is a key component of PCI compliance and protects both merchants and customers from data breaches.

Touchscreen POS

A POS terminal with a touch-sensitive display that allows staff to navigate menus, enter orders, and process payments by tapping the screen. Touchscreen POS systems are faster and more intuitive than keyboard-based systems, reducing training time. KwickOS reports that new operators achieve proficiency in under 5 minutes.

Time Theft

When employees are paid for time they didn't actually work — through early clock-ins, late clock-outs, extended breaks, or buddy punching. The American Payroll Association estimates that time theft costs employers up to 7% of gross payroll. Biometric POS systems with fingerprint authentication virtually eliminate time theft.

arrow_forward Time Theft Prevention Guide

U

Upselling

Suggesting a higher-priced version of what the customer is already ordering — such as a larger size, premium ingredient, or upgraded side. POS systems and self-ordering kiosks can automate upselling with prompts that appear at the right moment during the ordering process, increasing average check size without relying on server memory.

Unified Commerce

An approach that integrates all sales channels — in-store, online, mobile, kiosk, and delivery — into a single platform with shared inventory, customer data, and reporting. Unlike multichannel (separate systems per channel), unified commerce ensures consistency across every touchpoint. KwickOS is built as a unified commerce platform.

V

Void

Canceling a transaction or individual item before the order is finalized or settled. Different from a refund (which reverses a completed transaction), a void cancels an order that hasn't been processed yet. POS systems require manager authorization for voids and log every instance for audit and theft-prevention purposes.

VPN (Virtual Private Network)

An encrypted network connection that creates a secure tunnel between devices or locations over the public internet. In POS environments, VPNs connect remote locations to central servers, enable secure remote management, and isolate payment data from public network traffic. Essential for multi-location operations.

Variance Report

A report comparing expected vs. actual inventory usage, cash totals, or labor hours. Variances can indicate theft, waste, pricing errors, or procedural issues. POS systems generate variance reports automatically by comparing sales-driven expected usage against physical counts or cash drawer reconciliation.

W

Wireless Terminal

A payment terminal that connects via Wi-Fi or cellular data rather than a wired ethernet connection. Wireless terminals enable tableside payment, curbside checkout, and mobile vendor operations. They support the same payment methods as wired terminals — EMV chip, NFC contactless, and magnetic stripe.

Waste Tracking

Recording and analyzing food waste to identify patterns, reduce costs, and improve ordering accuracy. POS-integrated waste tracking logs why items were wasted (spoilage, overproduction, customer return, dropped), calculates the cost impact, and generates reports that help kitchen managers optimize prep quantities and purchasing.

Walk-In

A customer who arrives at a restaurant without a reservation. POS table management systems track walk-in vs. reservation guests, estimate wait times for walk-ins, and help hosts optimize seating to accommodate both walk-in traffic and reserved tables.
