An FBA adjustment makes your FBA warehouse in ConnectStock match what Amazon's FBA ledger says you have.
Steps
Go to ConnectStock, then Adjustments.
Click Bulk Adjustment at the top right. A pop up opens.
Under Select Adjustment Type, pick FBA Adjustment.
Under Select Warehouse, pick your FBA warehouse.
Under Select Stores, pick the Amazon stores to adjust, then click Apply.
Pick the inventory type: Type: All (recommended), Type: Sellable or Type: Unsellable.
Under Select Date, pick the date. The data is as of the end of that date.
Click Import.
Review and save
A New Adjustment page opens with the items and quantities to change.
Check that every line that adds stock has a cost. ConnectBooks fills in the item's default cost for you. Lines that remove stock are costed for you.
If you see "Some items are unmapped" at the top, click Resolve and map them. Then run the adjustment again.
Click Save. Nothing is saved until you do.
Other adjustment types
Under Select Adjustment Type you can also pick:
WFS Adjustment: the same, for Walmart WFS.
AWD Adjustment: for Amazon AWD.
Clear Negative Inventory: brings every item with negative stock in a warehouse up to 0, at its default cost.
Run it on a schedule
Click Schedule, next to Bulk Adjustment. Pick the adjustment type, warehouse, stores (not for Clear Negative Inventory), inventory type (for FBA and WFS) and how often it should run, then click Schedule.
If you already have a scheduled adjustment, click View Scheduled at the top of the Schedule pop up to see it.
Frequently asked questions
The button says Clear Warehouse, not Bulk Adjustment.
Your inventory file has no Amazon or Walmart stores, so only Clear Negative Inventory is available.
Why can't I pick today's date?
The report for today isn't ready yet, so for FBA, WFS and AWD adjustments the latest date is yesterday. Clear Negative Inventory lets you pick today.
Which inventory type should I pick?
Type: All, unless you only want to fix sellable or unsellable stock.
