Inventory sync month-end for ecommerce
Use month-end controls for ecommerce inventory sync, stock adjustments and cost of sales review.
Ecommerce accounting fails when payout reports, order data and VAT evidence drift apart. Inventory integrations help only if the month-end stock value, order flow and adjustments are reviewed together. This guide covers inventory sync month-end review for UK sellers that need clean software-ready records.
For wider context, use Integrations . If the topic affects a filing deadline, software choice or tax treatment, confirm the live position before acting. The workflow below is designed to keep the evidence in one place so the owner, bookkeeper and accountant can all review the same record.
Official point to verify
VAT Notice 700/22 says VAT-registered businesses must keep VAT records digitally and file VAT returns using software that can communicate with HMRC through the API platform. Check the current wording in VAT Notice 700/22 on Making Tax Digital for VAT before making a binding filing, software or tax decision.
What to control
| Area | Control | Why it matters |
|---|---|---|
| Stock value | Compare inventory system value to the accounts | Balance sheet stock should be supportable |
| COGS | Review cost of sales postings by channel | Margins need reliable cost data |
| Adjustments | Document write-offs, shrinkage and returns | Stock changes need reasons |
| Cut-off | Check orders shipped around month end | Timing affects sales and inventory |
Review routine
Reconcile by settlement, not just by bank receipt. Match orders, refunds, fees, reserves, currency differences and VAT evidence to the payout report, then post the net bank movement only after the gross entries make sense.
A useful review note should answer three questions: what source evidence was used, what judgement was applied, and who approved the treatment. Keep that note beside the transaction or period report rather than in a separate inbox.
Common mistakes
- Trusting stock sync without review
- Posting inventory adjustments with no explanation
- Ignoring returned stock until year end
The best prevention is a short, repeated checklist. If a control is too complicated to run every month or quarter, it will probably fail when the deadline is close.

Put the source data, review owner, exception list and submission evidence in the same system before the deadline arrives. That makes compliance work easier to check and much less dependent on memory.
