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

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.

Flow diagram: QuickBooks Online sends new orders to the InfiPlex Order Management System about every 15 minutes. InfiPlex pushes tracking numbers and real-time inventory back to QuickBooks Online, and routes orders to Your Warehouses, 3PL / WMS Partners, Sales Channels for fulfillment.
