How to Reconcile Amazon Business Split Shipments Against Credit Card Bank Feeds

The single greatest cause of confusion in small business bookkeeping is the Amazon Split Shipment Syndrome. A client places a single order totaling $342.50 containing 6 items. But when you look at the QuickBooks credit card bank feed, you don't see $342.50.

Instead, you see three separate, mysterious charges across different days: $112.45, $84.18, and $145.87. Because Amazon only charges the credit card when items physically ship from individual fulfillment centers, the bank feed splits the transaction unexpectedly.

The Rounding Trap: When accountants try to match these split transactions manually, dividing overall order sales tax across shipments introduces 1-cent rounding errors that break bank feed automated reconciliation rules.

Step 1: Match the Shipment Date & Amount

1 In your QuickBooks bank feed, click on the unmatched charge (e.g. $112.45 on Sep 12). Note the date and payment card last 4 digits.

Step 2: Open the Amazon Business Shipment Invoice

2 In Amazon, open the completed order invoice. Look for the sub-invoice labeled "Shipment 1 of 3: Shipped on Sep 12".

Step 3: Auto-Itemize with CartItemizer

3 Open CartItemizer. The extension isolates that specific shipment's line items, attributes the exact tax charged by that fulfillment warehouse, and balances the split lines to equal $112.45 down to the penny.
