POS Integration

Overview

Point-of-sale integration connects your physical retail operations with your online store, enabling unified inventory visibility, centralized order management, and consistent customer profiles across channels. When a customer buys in-store, the online store must reflect the updated inventory immediately; when they return an online order in-store, the refund must flow back to the payment gateway. This skill covers connecting Square and Shopify POS to your commerce platform, synchronizing inventory in real time, and handling cross-channel returns.

When to Use This Skill

• When opening a physical retail location alongside an existing online store
• When inventory discrepancies between in-store and online are causing oversells
• When customers expect to return online purchases in-store (omnichannel returns)
• When franchised or multi-location retail needs unified inventory and reporting
• When building a custom kiosk or tablet-based POS application
