Preparing ecommerce accounts for year end is one of the most important tasks for any online seller trading in the UK. Getting this process right ensures accurate profit reporting, correct Corporation Tax and VAT calculations, and a smooth Companies House and HMRC filing season. Ecommerce businesses face unique complications compared to traditional retailers, including multiple sales channels, bundled payment settlements, cross border VAT rules and constantly moving inventory. This guide walks through the practical steps sellers and their accountants should follow before closing the books.
Reconcile All Bank and Payment Accounts
The starting point for any year end close is making sure every bank account, credit card and payment processor balance matches the bookkeeping records. Ecommerce sellers typically receive money through several different channels, such as Shopify Payments, PayPal, Stripe and Amazon Settlements, and each of these platforms bundles sales, refunds, fees and chargebacks into a single net payout. This means the deposit landing in the bank rarely matches the gross sales figure, so every payout must be broken down into its underlying components before it is recorded correctly.
Timing differences are common around year end. An order placed just before the year end date may not settle into the bank until after it, so accountants should check that sales are matched to the period in which they were earned rather than the date cash arrived. Once this is done, every processor account should be fully reconciled with no unexplained gaps.
Review Income and Expense Classification
Once transactions are reconciled, income and expenditure need to be reviewed and classified correctly. This includes separating product sales from shipping income, discounts and marketplace fees, since lumping these together distorts gross margin reporting. On the expense side, common ecommerce specific costs include platform subscription fees, advertising and marketing spend, packaging and fulfilment costs, software tools and payment processing charges.
A dedicated business bank account and credit card should always be used, separate from personal finances, as this simplifies expense tracking considerably and reduces the risk of HMRC queries. Sellers operating as limited companies must also ensure allowable business expenses are properly claimed before filing the Corporation Tax return, known as form CT600.
Carry Out a Physical Stock Count and Value Inventory Correctly
Inventory is one of the largest areas of risk in ecommerce accounts, so a full physical stocktake should be carried out at year end rather than relying on estimated figures from earlier in the year. Every SKU and product variation should be counted and matched against both the ecommerce platform and the accounting system.
Once counted, stock must be valued at the lower of cost and net realisable value, in line with FRS 102 Section 13 for UK companies. Any unsellable, damaged or obsolete stock should be written off, because overstating inventory inflates profit and increases the tax bill unnecessarily.
Review VAT Treatment Across the Full Year
VAT deserves particular attention for UK ecommerce businesses. Rather than reviewing VAT quarter by quarter, accountants should look at the year as a whole to confirm that sales totals reported to HMRC align with the accounting records. This is especially important for sellers with international customers, since UK sales, exports and EU related transactions can each carry different VAT treatments.
Businesses with turnover below the current VAT registration threshold of ninety thousand pounds in any twelve month period are not required to register, but once this threshold is exceeded, VAT must be charged on sales and returns submitted on a regular schedule. Any discrepancy between platform reported sales and VAT return figures should be investigated and corrected before the year end accounts are finalised.
Check Accounts Receivable and Payable
Outstanding sales invoices and supplier bills need to be reviewed carefully at year end. On the receivable side, any overdue customer payments should be chased, and genuinely uncollectable balances should be written off as bad debts, since leaving them on the books artificially inflates taxable profit. On the payable side, all supplier bills should be confirmed as either settled or correctly recorded as a liability, with figures matched against supplier statements to catch disputed or duplicated invoices.
Account for Accruals, Prepayments and Deferred Income
Accurate year end accounts depend on adjusting entries that match income and costs to the correct accounting period. Accruals capture expenses incurred but not yet invoiced, such as utility costs used in one month but billed the next. Prepayments spread the cost of items like annual insurance or software subscriptions across the periods they actually cover. Deferred income accounts for customer payments received in advance for goods or subscriptions that will be delivered in a future period.
Update Fixed Assets and Depreciation
The fixed asset register should be updated to reflect any equipment, warehouse fittings or technology purchased or disposed of during the year. Depreciation should then be applied consistently, using either the straight line or reducing balance method, and any fully depreciated assets no longer in use should be removed from the register.
Verify Payroll and Pension Records
For ecommerce businesses with staff, payroll figures must be verified before year end accounts are drafted. This includes confirming that employee wages, director salaries, bonuses and benefits in kind have all been recorded, and that PAYE and National Insurance submissions match payroll figures. The final Full Payment Submission must reach HMRC on or before the last payday of the tax year, and P60s should be issued to employees by 31 May.
Prepare Draft Financial Statements
With reconciliations, inventory, VAT, receivables, payables and adjusting entries complete, a draft Profit and Loss Account and Balance Sheet can be prepared. These statements give ecommerce owners a clear picture of trading performance across all channels and should be reviewed for anything that looks unusual compared to prior years, such as an unexpected drop in margin or a spike in a particular expense category.
Plan Ahead for Corporation Tax and Filing Deadlines
Once the accounts are finalised, attention turns to Corporation Tax. UK limited companies need to calculate and submit Corporation Tax to HMRC and pay any amount due by the relevant deadline. Reviewing estimated tax payments made during the year and setting aside sufficient funds in a separate tax account helps avoid last minute cash flow pressure. A short tax planning conversation with an accountant at this stage can also highlight any reliefs or allowances still available before the filing deadline.
The table below summarises the core year end tasks and why each one matters for an ecommerce business.
| Task | Why it matters |
|---|---|
| Reconcile bank and payment accounts | Ensures bundled payouts from Shopify Payments, PayPal, Stripe and Amazon match recorded sales |
| Classify income and expenses | Protects accurate gross margin and expense reporting |
| Physical stocktake and valuation | Prevents overstated profit and incorrect tax liability |
| Full year VAT review | Confirms HMRC filings match actual sales across UK, EU and export channels |
| Receivables and payables check | Avoids inflated profit from uncollected debts or missed liabilities |
| Accruals and prepayments | Matches income and cost to the correct period |
| Fixed assets and depreciation | Keeps the asset register and profit figure accurate |
| Payroll and pension verification | Confirms PAYE, NI and pension figures reconcile before filing |
