ConnectBooks used to update FBA inventory based on financial events—so inventory only changed when money moved. That led to some inventory inaccuracies:
Lost or damaged items weren't removed from inventory until Amazon reimbursed you—sometimes months later.
Refunds added units back immediately, even if the return hadn't physically arrived yet.
Disposals and removals weren't tracked at all, since they don't generate a financial transaction.
Your inventory numbers simply didn't reflect what was actually in Amazon's warehouse.
What's changed
ConnectBooks now pulls from Amazon's FBA Ledger Report, which tracks actual physical inventory movements—not just when money changes hands.
Here's what that means in practice:
Orders still reduce inventory immediately when it ships.
Returns, losses, and damages are updated daily, recorded on the date the movement actually happened. For example, if Amazon receives 10 returned units on January 1, ConnectBooks logs that return for January 1.
Reimbursements no longer affect inventory counts. Instead, inventory is updated on the actual date Amazon lost or damaged the item—not when they paid you for it.
Disposals (items Amazon destroys) are now removed from inventory.
Removals (items sent back to you) are now tracked—more on this below.
How to enable it
Contact ConnectBooks Support, pick a start date, and you're set. Reports from that date forward will use the new system; older reports will stay on the old method. Note that the new system can't apply to any data before you joined ConnectBooks.
Two FBA warehouses, clearly separated
ConnectBooks now tracks two distinct FBA warehouses, so your inventory always reflects the real state of your Amazon stock:
FBA Sellable — Your main FBA warehouse. Holds inventory that's in good condition and available for sale.
FBA Unsellable — A separate warehouse for items Amazon has flagged as unsellable (damaged, expired, etc.). These units are still physically at Amazon, but they can't be sold.
Keeping them separate means your sellable inventory stays clean—you're never accidentally counting units that can't actually be sold. And when Amazon removes or disposes of an item, ConnectBooks automatically deducts it from the correct warehouse.
Handling removals
Removals were previously invisible to ConnectBooks. Now you have control over what happens to them.
If you use ConnectStock:
Sellable removals — you can either write them off as a loss by generating an adjustment, or move them to a separate "Sellable Removals" warehouse.
Unsellable removals — you can either write them off as a loss, or move them to an "Unsellable Removals" warehouse.
If you don't use ConnectStock: For each item, mark it as Sellable or Unsellable, then decide whether to remove it from inventory entirely or keep it.
Setting up your FBA warehouses in ConnectStock
Go to the Adjustments page and use the Bulk Adjustment feature to enter your starting inventory as of your chosen start date.
On the Inventory Files settings page, assign your FBA Sellable inventory to your default FBA Warehouse, and your FBA Unsellable inventory to a new FBA Unsellable Warehouse.
That's it—ConnectBooks handles the rest going forward. For any changes that need to be applied to past dates, contact ConnectBooks Support.
Quick comparison
Event | Old System | New System |
Orders | Reduced immediately | Reduced immediately |
Refunds | Added back immediately | Added back when FBA receives the return |
Lost / Damaged | Adjusted only if reimbursed | Adjusted on the actual date it happened |
Disposals | Not tracked | Removed from inventory |
Removals | Not tracked | Sent to removal warehouse or written off |
Financial Events | Affected inventory counts | No impact on inventory |
This applies to FBA inventory only. All other inventory behavior is unchanged.
