eCommerce & POS Integration FAQs

Common questions about ecommerce integration, POS integration and inventory synchronization.

How do I synchronize Shopify inventory across channels?

We connect Shopify to your POS, marketplaces and ERP through one shared inventory source. When stock changes anywhere — an online order, an in-store sale or a stock adjustment — every channel updates in real time, so you don't oversell or hold stale counts.

How do I automate ecommerce operations?

Automating ecommerce operations means connecting your storefronts, POS, inventory and accounting so orders flow to fulfilment, stock stays accurate, and sales post to your books automatically — removing the manual exports and re-entry between systems.

What is POS integration? (POS integration guide)

POS integration connects your point-of-sale system to your online store, inventory and accounting. In-store sales reduce the same stock pool as online orders, and combined takings post to QuickBooks, Sage or your ERP — giving one accurate view across every location.

Which platforms do you integrate?

Shopify, WooCommerce, Magento, Amazon and Walmart on the eCommerce side; Lightspeed, Square, Loyverse and VendHQ on POS; and QuickBooks, Sage and ERP systems for accounting — plus any platform with an available API.

Can you handle multiple stores and locations?

Yes. We consolidate multiple storefronts, POS outlets and warehouses into a single synchronized inventory and reporting view, with per-location tracking where you need it.
