Ecommerce Bookkeeping Services UK — What Online Sellers Need in 2026
Modern ecommerce bookkeeping is no longer just bank reconciliation. It is platform settlement accounting, VAT evidence, inventory valuation, SKU profitability, MTD software, cash-flow planning and clean management reports.
Why ecommerce bookkeeping is different from normal bookkeeping
Traditional bookkeeping usually starts with a bank statement and a list of invoices. Ecommerce bookkeeping starts with marketplace settlements, payment gateways, refunds, advertising invoices, shipping charges, fulfilment fees, inventory movements and tax rules that change depending on where the buyer is located. A simple bank-feed-only approach can make a seller look profitable when the business is actually losing money after Amazon fees, Shopify payment charges, eBay promoted listing costs, stock write-offs and returns.
Our ecommerce bookkeeping services UK workflow is designed around the reality of online selling. We reconcile Amazon Seller Central, Shopify Payments, PayPal, Stripe, Klarna, TikTok Shop settlements, eBay Managed Payments, Etsy Payments, WooCommerce, OnBuy, Wayfair and other platforms before the numbers hit your profit and loss report. That means each month you can see actual sales, true COGS, gross margin, channel fees, advertising spend, fulfilment costs, VAT position and net profit.
For UK online sellers in 2026, clean ecommerce accounting also matters because HMRC expects accurate digital records, VAT-registered businesses are already inside Making Tax Digital for VAT, and sole traders crossing the new MTD for Income Tax thresholds need software-based quarterly reporting. The right bookkeeping system protects you from late returns, missed claims, overstated profits, underpaid VAT and poor stock-buying decisions.
Settlement-first bookkeeping
Amazon, Shopify, eBay and TikTok Shop do not deposit one clean sales figure into your bank. They deduct commissions, fulfilment fees, refunds, claims, shipping, chargebacks and reserve balances before paying out. We split each settlement correctly so your books show real revenue and real costs.
- Sales separated from platform fees
- Refunds and returns posted correctly
- Gift cards, reserves and chargebacks tracked
- Multi-currency payouts reconciled
Inventory and COGS tracking
Without inventory accounting, profit is usually wrong. Stock purchases should sit on the balance sheet until sold, then move into cost of goods sold using a consistent valuation method. This gives a cleaner gross margin and more reliable tax reporting.
- FIFO or weighted-average cost support
- FBA stock movements and removals reviewed
- Damaged, lost and written-off inventory recorded
- Landed cost allocation for imports
VAT-ready ecommerce records
VAT for ecommerce sellers can involve UK standard rate sales, zero-rated products, reverse charges, import VAT, marketplace facilitator rules, EU sales, Northern Ireland movements and OSS/IOSS evidence. We build a clean VAT audit trail before each return is submitted.
- UK VAT return preparation
- Input VAT checks on supplier and software bills
- Postponed VAT Accounting review
- Marketplace VAT evidence retained
Profit reports you can actually use
A basic year-end profit figure is not enough for ecommerce. You need monthly channel reports, SKU margin trends, advertising efficiency, stock cash tied up, tax reserves and reorder visibility so you can make decisions before cash runs out.
- Monthly P&L and balance sheet
- Channel-level profit report
- COGS and gross margin review
- Cash-flow and tax reserve guidance
2026 UK Ecommerce Compliance Roadmap
Important accounting, VAT, corporation tax and Making Tax Digital points online sellers should build into their bookkeeping system.
VAT registration, MTD and corporation tax are now bookkeeping issues
Good bookkeeping does more than keep records tidy. It tells you when you are close to the UK VAT threshold, gives you the data needed for a VAT return, separates taxable and non-taxable sales, tracks input VAT on software and supplier bills, and creates the evidence your accountant needs for corporation tax or self assessment. In ecommerce, missing one platform feed can distort every tax calculation.
In 2026, ecommerce businesses should review their bookkeeping every month, not once at year end. The reason is simple: the VAT threshold is measured on a rolling 12-month basis, marketplace settlements change constantly, and stock purchases can make bank balances misleading. A seller might have low cash because stock has been bought, but still have a taxable profit; another seller might have high bank deposits but low actual profit after refunds, FBA fees and advertising.
| Area | 2026 point to watch | What your bookkeeping must show | Helpful external resource |
|---|---|---|---|
| VAT registration | Monitor taxable turnover against the UK VAT threshold on a rolling 12-month basis. | Monthly sales by VAT category, marketplace, country and product type. | GOV.UK VAT registration |
| MTD for VAT | VAT-registered businesses need digital VAT records and compatible software workflows. | VAT return boxes linked to digital source records, not manual guesswork. | Charge, reclaim and record VAT |
| MTD for Income Tax | Sole traders with qualifying income over the staged thresholds need to prepare for quarterly digital updates. | Digital records for income and expenses, ready for software submission. | MTD for Income Tax guide |
| Corporation Tax | Limited companies need accurate profit figures, expense claims and stock values for the company tax return. | Year-end accounts, director loan account, payroll, dividends and inventory valuation. | Corporation Tax rates |
| Import VAT & duty | Imported stock needs landed cost tracking and supporting customs records. | Supplier cost, freight, duty, import VAT, clearance fees and exchange rates. | Import goods into the UK |
Important 2026 note for growing sellers
If your online store is moving quickly, do not wait until year end to check VAT or tax. Run a monthly rolling 12-month sales review, keep platform reports, retain import evidence and make sure every marketplace settlement is reconciled. This is especially important for Amazon FBA, Shopify, eBay, Etsy and TikTok Shop sellers using multiple payment processors.
What Our Monthly Ecommerce Bookkeeping Service Includes
A clear monthly close process built for UK online sellers who need reliable numbers before making stock, pricing and tax decisions.
Platform connection and data checks
We connect and review data from your selling channels, payment gateways and bank accounts so your accounting software receives complete, accurate information.
- Amazon Seller Central, Shopify, eBay and Etsy feeds
- PayPal, Stripe, Klarna and Shopify Payments
- Bank and credit card feeds
- Software integration checks each month
Settlement reconciliation
We split deposits into sales, VAT, refunds, fees, chargebacks and reserves. This prevents the common mistake of posting every payout as income.
- Amazon settlement report mapping
- Shopify payout reconciliation
- eBay Managed Payments breakdown
- TikTok Shop settlement checks
Expense coding and receipt capture
We categorise supplier bills, software subscriptions, advertising invoices, freight costs, storage charges, returns costs and professional fees into the right accounts.
- COGS vs overhead separation
- Advertising by platform
- Import and freight cost allocation
- Dext or receipt capture setup
Monthly reports and review notes
Once the month is closed, you receive reports that explain what happened and what to watch next. Reports are written for business owners, not just accountants.
- Profit and loss report
- Balance sheet and cash summary
- Channel profit snapshot
- Tax reserve and cash-flow notes
| Monthly step | What we do | Why it matters for ecommerce sellers |
|---|---|---|
| 1. Data completeness check | Confirm all platforms, banks, cards, payment gateways and software feeds are connected and current. | Missing data creates false profit, incorrect VAT and unreliable cash-flow reports. |
| 2. Settlement posting | Map marketplace and payment processor payouts into sales, fees, VAT, refunds and reserves. | You see real sales and real costs instead of one misleading bank deposit. |
| 3. Inventory and COGS review | Update inventory asset values, stock write-offs, landed costs and cost of goods sold. | Gross margin becomes accurate, and reorder decisions become data-led. |
| 4. VAT and tax review | Check VAT coding, taxable turnover, import VAT, reverse charges and tax reserve requirements. | Reduces the risk of late VAT registration, underpaid VAT and unexpected tax bills. |
| 5. Month-end reporting | Send reports with plain-English notes, action points and questions for the next month. | You know which products and platforms are actually producing profit. |
Platform-Specific Ecommerce Accounting Workflows
Each platform has different reports, fees and reconciliation challenges. We build the accounting workflow around the way your business actually sells.
Amazon FBA bookkeeping workflow
Amazon settlements include referral fees, FBA fulfilment fees, storage, coupons, reimbursements, subscription fees, refunds, inventory adjustments and advertising. We use settlement automation plus manual review to ensure the numbers are correctly mapped.
- FBA fee and referral fee categorisation
- Reimbursement and lost inventory tracking
- Advertising and coupon spend separation
- Inventory received, removed and written off
Shopify bookkeeping workflow
Shopify sellers often use several payment providers, apps and fulfilment tools. We reconcile Shopify Payments, PayPal, Klarna, Stripe and app costs so revenue matches orders and fees are visible.
- Shopify payout reconciliation
- Gift card and discount handling
- App subscription review
- Multi-currency sales tracking
eBay bookkeeping workflow
eBay Managed Payments needs clean mapping for sales, final value fees, promoted listings, refunds, postage labels and international buyer charges. We keep eBay revenue separate from shipping and advertising costs.
- Managed Payments deposits matched to orders
- Promoted listings posted as advertising
- Refunds and claims reconciled
- International sales reviewed
TikTok Shop bookkeeping workflow
TikTok Shop can include affiliate commission, creator costs, fulfilment charges, vouchers, customer refunds and settlement timing differences. We make the settlement report readable and tax-ready.
- Affiliate commission tracking
- Fulfilled by TikTok fee review
- Voucher and discount accounting
- Settlement timing checks
Multi-channel ecommerce bookkeeping: the bigger challenge
Multi-channel sellers often have the hardest bookkeeping problem. The same product may sell on Amazon, Shopify, eBay, Etsy and TikTok Shop at different prices, with different fulfilment costs and different return rates. If all sales are merged into one income account, you cannot see which channel is actually profitable. A clear chart of accounts should separate marketplace sales, direct-to-consumer sales, platform fees, advertising costs, fulfilment costs and inventory movement.
For example, a Shopify sale may look more profitable than an Amazon FBA sale because there is no FBA fulfilment fee. But once you include card processing, app costs, warehouse pick-and-pack, returns handling and paid social advertising, the true channel margin may be lower. Proper ecommerce accounting compares each channel on the same basis so you can make reliable decisions.
Inventory Accounting, COGS Tracking and SKU Profitability
Know the true profit of every product after stock cost, freight, duty, marketplace fees, returns, advertising and storage.
Why COGS tracking changes your profit
Many ecommerce sellers expense stock as soon as they buy it. That may feel simple, but it can make monthly profit reports almost useless. If you buy three months of inventory in January, your January profit looks terrible and the next two months look artificially strong. Proper inventory accounting keeps stock as an asset until it sells. Only the cost of the units sold is moved into COGS.
This matters for Amazon FBA, Shopify, eBay and TikTok Shop sellers because stock buying drives cash-flow. You might be profitable on paper but short of cash because money is tied up in inventory. Or you might have plenty of cash after a strong sales month but a large reorder and VAT bill coming soon. Accurate COGS reporting gives you a cleaner view of margins, stock value and tax planning.
| Profit area | Common seller mistake | Better bookkeeping treatment |
|---|---|---|
| Stock purchases | Posting all stock purchases directly to expenses. | Record stock as inventory asset, then move cost to COGS when sold. |
| Freight and duty | Leaving freight as a general overhead. | Allocate freight, duty and import handling into landed cost per unit where appropriate. |
| Returns | Ignoring returned units or mixing refunds with sales. | Separate customer refunds, restocked units, damaged stock and write-offs. |
| Amazon reimbursements | Not checking whether Amazon paid for lost or damaged inventory. | Track reimbursements separately and reconcile them to settlement reports. |
| Advertising | Looking only at sales revenue and ignoring PPC or creator commission. | Track ad spend by channel and compare it to gross profit, not just revenue. |
Best practice
Review gross margin by product family every month. If your bestseller has high sales but low gross margin after COGS, fees and advertising, it may be draining cash instead of creating profit. A bookkeeping system should highlight that before you reorder.
Ecommerce Bookkeeping Cleanup for Messy Xero or QuickBooks Files
Already have a bookkeeping file but the numbers do not look right? We clean up ecommerce accounts and rebuild the system without changing your whole business overnight.
When you need a bookkeeping cleanup
You may need a cleanup if your bank balance in Xero or QuickBooks does not match the real bank, Amazon deposits are posted as total income, Shopify payouts are duplicated, PayPal is unreconciled, VAT looks too high or too low, stock purchases are mixed with overheads, or your accountant asks for reports that you cannot produce. These problems are common when an ecommerce business grows faster than its bookkeeping setup.
Our cleanup process starts with diagnosis. We review your chart of accounts, bank feeds, platform connections, sales tax/VAT codes, inventory treatment, prior VAT returns, unreconciled transactions and suspense accounts. Then we create a practical correction plan: fix the most important errors first, protect tax deadlines, and rebuild the monthly process so the same problems do not return.
Diagnostic review
We review your accounting software, platform reports, bank feeds, VAT setup, chart of accounts, integrations and prior-year balances to identify the core issues.
Cleanup priority plan
We separate urgent compliance issues from reporting improvements. VAT, bank reconciliation and tax deadlines come first; dashboards and refinements come after the file is reliable.
Historical correction
We correct settlement postings, duplicated sales, uncoded expenses, inventory balances, old suspense items and missing payment gateway activity.
Automation setup
We configure Xero, QuickBooks, A2X, Link My Books, Dext and reporting workflows so the bookkeeping stays clean month after month.
Monthly close handover
You receive clear reports, action points and a monthly checklist so you know what is complete, what needs your input and what to prepare for tax deadlines.
Ecommerce KPI Dashboard: The Numbers We Track Every Month
Bookkeeping should help you grow. Our reports highlight the numbers that affect cash, profit and stock decisions.
| KPI | What it tells you | Why it matters |
|---|---|---|
| Gross margin | Sales after COGS but before overheads. | Shows whether products are priced correctly and landed costs are under control. |
| Contribution margin | Profit after COGS, marketplace fees, fulfilment and advertising. | Helps compare Amazon, Shopify, eBay, Etsy and TikTok Shop on a fair basis. |
| Advertising cost of sales | PPC or paid social spend relative to revenue. | Shows whether sales growth is profitable or being bought at too high a cost. |
| Stock turn | How quickly inventory converts into sales. | Slow stock ties up cash and may trigger storage fees, markdowns or write-offs. |
| Cash conversion cycle | Time between paying suppliers and receiving cash from sales. | Helps plan reorder timing, VAT payments, payroll and tax reserves. |
| VAT and tax reserve | Estimated cash to set aside for tax liabilities. | Prevents the common ecommerce problem of spending tax money on stock. |
How better reports improve buying decisions
Most ecommerce owners focus on revenue because it is easy to see inside Amazon, Shopify or eBay. But revenue does not pay the bills. Your monthly ecommerce bookkeeping report should show whether each product creates enough gross profit to cover ads, staff, software, VAT, corporation tax, stock finance and owner pay. When the report is built properly, it becomes a buying tool: reorder winners, reduce weak lines, renegotiate supplier prices and stop scaling products with poor contribution margin.
For UK ecommerce sellers, this is especially useful before peak periods such as Prime Day, Black Friday, Christmas and seasonal stock launches. A product that looks profitable in August can become unprofitable in November if advertising costs rise, refunds increase or storage fees build up. Monthly bookkeeping gives you the warning early enough to act.

Ecommerce Bookkeeping — Frequently Asked Questions
Answers to the most common questions from UK online sellers
If you are a limited company or VAT registered, you are legally required to maintain accurate accounts and file returns on time. Even as a sole trader under the VAT threshold, professional bookkeeping saves you hours every month, ensures you claim all allowable expenses, minimizes your tax bill, and gives you accurate profit data to make better business decisions. Most clients find the tax savings alone more than cover our fees.
We primarily use Xero and QuickBooks Online — both are cloud-based, Making Tax Digital compliant, and integrate with all major selling platforms. We also use specialist ecommerce tools including A2X (for Amazon, Shopify, eBay settlement automation), Link My Books, Dext for receipt scanning, and Sage Business Cloud. All software fees are included in our monthly packages. See our best accounting software guide for a full comparison.
UK businesses must register for VAT when their taxable turnover exceeds £90,000 in any 12-month rolling period (as of 2026). However, voluntary registration can be beneficial even below this threshold, as you can reclaim VAT on business purchases. Amazon FBA sellers sending stock to EU fulfilment centres may also need to register for VAT in EU countries. Read our full VAT registration guide for ecommerce sellers.
Making Tax Digital (MTD) is HMRC's initiative requiring businesses to keep digital records and submit returns using compatible software. MTD for VAT applies to all VAT-registered businesses — you must use HMRC-approved software (like Xero or QuickBooks) to file VAT returns. MTD for Income Tax is being extended from 2026 to sole traders and landlords above the income threshold. All our packages are fully MTD compliant. See our MTD for ecommerce guide.
Absolutely — multi-channel accounting is our speciality. We handle Amazon, Shopify, eBay, Etsy, TikTok Shop, OnBuy, Walmart, Wayfair, and more, consolidated into a single clean set of accounts. Our Growth and Scale packages include unlimited platforms. You'll get a consolidated P&L plus individual channel profitability reports so you know exactly which platforms are making you money. See our multi-channel accounting page for details.
Setup takes 3–5 working days to connect platforms and configure software. Catch-up bookkeeping for a business that is a few months behind typically takes 1–2 weeks. We've successfully caught up clients who are 18 months behind. Once current, monthly bookkeeping is completed within 5 working days of month-end and monthly reports are delivered by the 10th of each month.
Amazon owes money back to sellers for lost inventory in fulfilment centres, damaged goods, overcharged FBA fees, incorrect weight/dimension charges, and failed returns. Amazon does not always automatically reimburse these — you have to claim them. Our Amazon reimbursement tracking service audits your account and files claims on your behalf. The average recovery for our clients is £1,800, with some sellers recovering £5,000+.
Yes — we offer a completely free 30-minute consultation call with no obligation. During this call we review your business, current accounting setup, platforms you sell on, and tax position. We'll recommend the right service package and give you an honest assessment of what we can improve. There are no setup fees and no long-term contracts. Use the form below to book your free consultation today.
Ecommerce bookkeeping has to reconcile marketplace settlements, payment gateways, refunds, returns, platform fees, stock movements, advertising spend, VAT, import costs and multi-channel sales. A normal bank-feed approach often posts deposits as income and misses the deductions already taken by Amazon, Shopify, eBay, Etsy, TikTok Shop, PayPal or Stripe. Specialist ecommerce bookkeeping separates each component so your profit and VAT reports are accurate.
Yes. We review your current accounting file, platform feeds, chart of accounts, VAT codes, bank reconciliation, payment gateways, inventory balances and historical settlement postings. Then we correct errors, remove duplicates, rebuild mappings and set up a reliable monthly close process. Cleanup is especially useful when Amazon deposits have been posted as sales, Shopify payouts are duplicated, PayPal is unreconciled, or stock purchases have been mixed with general expenses.
Yes. We can track inventory using FIFO, weighted average cost, landed cost allocation or a practical method agreed with your accountant. For Amazon FBA sellers, we review FBA stock movements, reimbursements, removals and damaged inventory. For Shopify and multi-channel sellers, we help connect inventory software, stock reports and accounting software so cost of goods sold is matched to actual sales instead of guessed at year end.
Monthly is the best rhythm for most ecommerce sellers. A monthly review catches VAT threshold issues, low-margin products, rising advertising costs, refund spikes, stock cash problems and missing platform data before they become expensive. Fast-growing sellers, VAT-registered businesses and multi-channel brands should not wait until year end because the data will be too old to support pricing, stock and tax decisions.
Yes. If you are a sole trader ecommerce seller and your qualifying income brings you into Making Tax Digital for Income Tax, we can help you move from spreadsheets or manual records to compatible digital software. The workflow includes digital record keeping, income and expense categorisation, quarterly update preparation and a final tax return process that matches HMRC requirements.
Yes. We can design your chart of accounts and reporting setup to show profit by channel. This means sales, refunds, fees, advertising and fulfilment costs are separated where possible. Channel-level reporting helps you see whether Amazon FBA, Shopify direct sales, eBay, Etsy, TikTok Shop or wholesale is producing the strongest contribution margin after costs.
