QuickBooks Online Integration: the books stay clean as you add channels
QuickBooks Online is where most growing sellers keep their finances — but its native inventory tracking wasn't built to reconcile multichannel stock. The InfiPlex™ OMS syncs orders and revenue from every sales channel into QuickBooks automatically, while handling the real-time, multi-location inventory sync QuickBooks can't do alone.
- Keeps QuickBooks as Your BooksOrders & revenue sync in, no re-keying
- Real Multichannel InventoryWhat QuickBooks' native tracking can't do alone
- USA-Based Support TeamOnboarding, mapping & training included
How it works
How the InfiPlex QuickBooks integration works
QuickBooks Online Plus and Advanced include basic inventory tracking, but it's built around a single location and doesn't reconcile stock across Amazon, Shopify, Walmart, and a webstore at once — sellers who try end up re-entering orders or watching QuickBooks quantities drift from reality. InfiPlex takes over the multichannel order and inventory layer: orders from every connected channel sync into QuickBooks as sales, while the real-time inventory truth lives in the OMS and pushes accurate counts everywhere, including back to QuickBooks.

Everything the QuickBooks integration handles for you
-
Orders Sync as Sales
Marketplace and storefront orders push into QuickBooks Online as sales records automatically — no re-keying settlement reports.

Real Multichannel Inventory
InfiPlex maintains one live inventory pool across every channel, since QuickBooks' native tracking is built for a single location.

Revenue & COGS Mapped
Fee, refund, and cost-of-goods mapping configured with your bookkeeper during onboarding, so margins stay accurate.

Any Sales Channel
Amazon, Shopify, Walmart, eBay, and 130+ more all sync into the same QuickBooks connection.
