Although transaction scenarios can vary from business to business, a basic checkout flow involving an integrated PoS system has the following steps.

  • To begin a transaction, a cashier at the counter or a customer at a self-service kiosk scans an item’s barcode. The connected display shows item details, quantity, price, as well as subtotal and total amounts.
  • Then, as soon as the customer chooses to pay with cash or a payment card, the PoS system initiates either cash drawer opening or credit card reader activation. In a cashless payment, the credit card reader contacts the payment processing service for payment authorization and sends a confirmation to the PoS system to complete the transaction.
  • Simultaneously, the PoS system sends inventory and sales data to the accounting software, inventory management system, and ERP, where it’s recorded and updated.
  • If a retailer also sells products through digital channels, an integrated PoS system syncs catalogs, orders, and inventory data with the online store in real time.

Common PoS integration options

We can integrate your PoS system with a web-based or mobile ecommerce solution and ready-to-use business applications through existing APIs or connectors. We can also build custom connectors that are fully tailored to your unique software and workflows. Here is a rundown of useful PoS integrations for companies of different business verticals, sizes, and sales models that can streamline daily operations, facilitate sales, and boost overall business efficiency.

Hardware options

PoS systems can either connect to devices from various brands or integrate exclusively with proprietary equipment. Retail hardware and equipment connected to a PoS system automate data input and output, speed up transaction processing, and improve customer experience.

PoS terminals

Connecting a PoS application with a stationary or handheld terminal, businesses can accept orders and in-person payments, accurately process transactions, and seamlessly transmit transaction data to PoS software and other integrated systems.

Credit card readers

With an integrated credit card reader, companies can faster ring up customers and complete transactions. The device captures information from a customer’s credit or debit card, sends it to the merchant’s payment processing service for authorization, and then communicates payment confirmation or decline to the PoS system to finalize the transaction.

Cash drawers

Companies that accept cash payments can link their cash drawers directly to the PoS system to track cash-ins and cash-outs, reconcile cash balances, manage cashier permissions, and control cash drawer opening.

Barcode scanners

Retailers use barcode scanners to identify and quickly process items at checkout, look up prices, automatically apply discounts for specific products, pick stock for shipping, and update stock levels in real time. Integrated barcode scanners can also be programmed to scan IDs for age verification and loyalty program cards for reward assignment.

Additional displays

For better customer engagement and transparent checkout, merchants can equip their PoS setup with a second customer-facing display to show transaction details, suggest payment methods, put up promotions, and ask for interactive feedback. In restaurants, additional screens can be used for customer tipping or serve as kitchen displays with a real-time list of orders for the staff.


A printer linked to a PoS system allows users to print sale receipts, order tickets, coupons, end-of-day sales summaries, and other documents for accounting.
