Inventory Sync

How Inventory Syncing Works

Breaking down the Connex inventory sync and how it works.

Is there a demo?

Here is a demo:

How It Works

Here is a sample scenario:

  • After purchase orders or inventory adjustments, QuickBooks has inventory items with a quantity on hand. In this example, QuickBooks has an item called "redwine" with a quantity on hand of 20.
  • Connex queries your e-commerce solution for new orders.
  • These orders are inserted into QuickBooks. Each order will decrement inventory in QuickBooks.
  • The new inventory is the current amount (20) minus what was ordered (5). If there was one order for 5 redwine, you now have 15 bottles in QuickBooks.
  • Connex queries QuickBooks for recently modified items. An inventory adjustment will update an item, so it will be returned in this query.
  • Your e-commerce solution will be sent the new number (15) associated with the affected item "redwine". If the QuickBooks item name and the SKU match, then your e-commerce solution and QuickBooks have the same inventory.


There will always be a delay between QuickBooks and your website. The delay's length depends on several factors:

  • How often does the sync run?
  • How many orders are there to insert into QuickBooks?
  • How many items have been updated in QuickBooks?
  • How long does your website take to update the items?


If you make a refund receipt or credit memo in QuickBooks, the quantity on hand for the item will increase. This new stock will reach your website. 

Where should I enter inventory updates?

If Connex creates a new item in QuickBooks, then Connex will sync its initial quantity to QuickBooks. If you make quantity updates in your website by adjusting the qty on hand, those will not sync to existing items. There are two ways to sync inventory:

Initial Sync

  1. Create new items in QuickBooks and sync the initial quantity.
  2. Decrement the inventory through sales receipts or invoices.


  1. Go to your QuickBooks product list.
  2. Edit an item.
  3. Enter an inventory adjustment.
  4. Connex will sync the adjustments back to WooCommerce.

Product Matching

Products must have matching SKU's between QuickBooks and the chosen integration to update inventory.
