Step by step
- In Seller Central, open the inventory ledger’s summary view and choose your year end as the date. Download it.
- Add stock you hold outside Amazon: your own unit, a 3PL, goods on their way to you that you’d paid for. See FBA stock at the year end.
- Work out what each product cost: the supplier’s price plus shipping, import duty and delivery into Amazon’s warehouses1. Leave out Amazon’s fees and storage.
- Check for anything worth less than it cost, such as units Amazon marks as damaged, and write those down. See how to value stock.
Check your company’s dates and set a reminder
Search the Companies House register. Your company page shows its filing dates, what to file next and a reminder you can set.
On Fileyear
On the year-end questions, drop the ledger download (or Amazon’s Manage FBA Inventory report), and add a cost list with each SKU’s unit cost, or type what the goods cost in total.
Why it matters
Without closing stock, everything bought in the year is a cost of this year, so profit and Corporation Tax are understated in a year stock grows and overstated in a year it shrinks. HMRC takes the stock figure in the accounts as its starting point2.
