Most Common UK Seller Questions
Do marketplace deposits equal sales?
No. Amazon, eBay and Shopify payouts usually include deductions such as fees, refunds, ads, chargebacks, shipping labels and reserves, so gross sales must be reconciled separately.
When should I register for VAT?
UK sellers must monitor taxable turnover and register if they go over the current VAT registration threshold. GOV.UK lists the threshold as more than £90,000.
Does MTD apply to ecommerce sellers?
VAT-registered businesses generally need compatible software for VAT records and returns. From 6 April 2026, Making Tax Digital for Income Tax begins for some sole traders and landlords.
How should stock be handled?
Stock purchases, landed costs, packaging, fulfilment costs and cost of goods sold should be reviewed carefully so your gross margin and net profit reports are meaningful.
How often should books be updated?
Monthly bookkeeping is best for most sellers because it keeps VAT checks, stock decisions, cash flow, fee tracking and tax planning under control.
UK Ecommerce Bookkeeping Basics for 2026
Ecommerce bookkeeping is more detailed than simply matching bank transactions. A UK online seller may receive payouts from Amazon, eBay, Shopify, PayPal, Stripe, Klarna, Etsy or other marketplaces, but those payouts are usually net amounts after fees, refunds and adjustments. Good bookkeeping separates the full trading activity so you can see sales, costs, VAT, fees, stock movement and true profit.
For Amazon, eBay and Shopify sellers, accurate books help with Self Assessment, company accounts, VAT returns, Making Tax Digital, cash-flow planning, business loan applications and product-level decisions. The goal is not only tax compliance — it is also better decision-making.

What Records Should UK Ecommerce Sellers Keep?
UK sellers should keep clear records of income, business expenses, marketplace statements, payment processor reports, stock purchases, supplier invoices, courier charges, advertising spend, software subscriptions, bank statements, VAT records if registered, and year-end tax records. A reliable bookkeeping system should allow you to trace a payout back to the underlying sales, refunds and deductions.
- Marketplace settlement reports from Amazon, eBay, Shopify, Etsy and other channels.
- Payment gateway records from PayPal, Stripe, Klarna, Shopify Payments and bank accounts.
- Supplier invoices, import documents, stock purchase records and landed cost details.
- Advertising, software, shipping, packaging, storage, fulfilment and subscription expenses.
- VAT evidence, digital records and Making Tax Digital software records where applicable.
- Monthly profit and loss, balance sheet, aged payables and cash-flow reports.
Why Bank-Only Bookkeeping Can Be Risky
Bank-only bookkeeping records the money that lands in the bank, but ecommerce platforms often deduct many costs before paying you. If only the payout is recorded as sales, your turnover, fees and VAT reporting can be inaccurate. This can also hide which products, platforms or campaigns are actually profitable.
For cleaner reporting, sellers should reconcile marketplace reports and payment gateway reports against deposits. This helps separate gross income from fees, refunds, advertising, shipping labels, reimbursements and reserves.
Amazon, eBay, Shopify and Multi-Channel Bookkeeping FAQs
Each ecommerce platform creates different bookkeeping challenges. Amazon settlement reports are not the same as eBay managed payments or Shopify payout reports, and multi-channel sellers must also prevent duplicate income when data flows through several apps.
Amazon Seller Bookkeeping FAQs UK
Amazon sellers should review settlements, referral fees, FBA fulfilment fees, storage fees, advertising costs, refunds, reimbursements, inventory adjustments and reserve balances. Your accounting software should not simply record Amazon deposits as sales because the deposit is usually a net settlement figure.

eBay Seller Bookkeeping FAQs UK
eBay sellers should track managed payments, promoted listings, seller fees, postage labels, returns, refunds, international sales, VAT records and payment holds. Clean bookkeeping should separate gross eBay sales from fees and refunds so you can understand true product margin.
For more detail, visit eBay seller bookkeeping services.
Shopify Bookkeeping FAQs UK
Shopify bookkeeping often involves multiple payment methods such as Shopify Payments, PayPal, Stripe, Klarna, manual payments and gift cards. Payouts should be matched to orders, fees, refunds, chargebacks, app subscriptions and VAT treatment where relevant.

Multi-Channel Ecommerce Bookkeeping
Multi-channel sellers need a workflow that prevents duplicate sales, keeps each platform separate, reconciles each payment gateway and produces consolidated reports. The most useful monthly reports show platform-by-platform sales, fee percentage, advertising spend, gross margin, stock cash tied up and net profit.
VAT, Tax and Making Tax Digital FAQs for Ecommerce Sellers
VAT, Self Assessment and Making Tax Digital are common sources of confusion for ecommerce sellers. The right answer depends on your business structure, taxable turnover, VAT status, sales channels, locations, goods sold and accounting records. The points below are general guidance and should be checked against your exact circumstances.
VAT Registration Threshold for UK Ecommerce Sellers
GOV.UK says you must register for VAT if your total taxable turnover for the last 12 months goes over £90,000. GOV.UK also lists the deregistration threshold as £88,000. Ecommerce sellers should monitor rolling 12-month taxable turnover rather than waiting until the financial year ends.
Official guidance: Register for VAT and VAT thresholds.
Making Tax Digital for VAT
GOV.UK states that VAT-registered businesses should keep VAT records and submit VAT Returns using compatible software under Making Tax Digital for VAT, unless exempt. This means VAT bookkeeping should be digital, organised and capable of supporting return preparation.
Official guidance: Making Tax Digital for VAT and compatible VAT software.
Making Tax Digital for Income Tax from April 2026
GOV.UK says that from 6 April 2026, sole traders and landlords must use Making Tax Digital for Income Tax if their total annual income from self-employment and property is over £50,000. Some ecommerce sole traders may therefore need to prepare their systems before the start date.
Official guidance: Making Tax Digital for Income Tax and choose MTD Income Tax software.
Self Assessment Deadlines
GOV.UK explains that you must tell HMRC by 5 October if you need to complete a tax return for the previous year and meet the relevant conditions. For 2025 to 2026 returns, GOV.UK lists 31 October 2026 as the paper filing deadline and 31 January 2027 as the online filing deadline.
Official guidance: Self Assessment overview and Self Assessment deadlines.

Monthly Ecommerce Bookkeeping Process
1
Collect Platform and Payment Data
Download or connect Amazon, eBay, Shopify, PayPal, Stripe, bank, supplier and expense records so the month has complete data.
2
Reconcile Payouts and Fees
Match each payout to gross sales, refunds, marketplace fees, advertising deductions, shipping charges, reserves and payment gateway fees.
3
Review VAT, Stock and Profit
Check VAT coding, stock costs, cost of goods sold, gross margin, net profit, cash flow and any unusual balances before finalising reports.
Bookkeeping Software, Digital Records and Compliance FAQs
The best bookkeeping software depends on transaction volume, sales channels, VAT status, reporting needs and whether you sell through one platform or multiple marketplaces. Software can help, but it still needs the right setup, chart of accounts, integrations and monthly review process.
Should Ecommerce Sellers Use Xero, QuickBooks or Spreadsheets?
Spreadsheets may work for very small sellers with low transaction volumes, but growing ecommerce businesses usually benefit from accounting software such as Xero or QuickBooks plus appropriate marketplace connector apps. VAT-registered sellers and sellers preparing for Making Tax Digital should be especially careful about digital record-keeping and compatible software.
Which Reports Should Sellers Review Monthly?
A useful ecommerce month-end pack should include a profit and loss report, balance sheet, cash-flow view, marketplace fee report, advertising spend report, stock and cost of goods sold review, VAT liability check if registered, and platform-by-platform sales summary.
Common Bookkeeping Mistakes to Avoid
- Recording marketplace deposits as gross sales without separating fees and refunds.
- Importing the same sales twice through both platform apps and bank feeds.
- Ignoring PayPal, Stripe or Shopify Payments clearing account balances.
- Posting stock purchases as ordinary expenses without reviewing cost of goods sold.
- Forgetting advertising, storage, fulfilment, packaging and shipping costs.
- Leaving VAT coding until the return deadline instead of reviewing monthly.
- Not checking whether reports match marketplace statements and bank deposits.
Stock, Marketplace Fees, Expenses and Profit Reporting FAQs
Many ecommerce sellers focus on revenue, but profit depends on gross margin, marketplace fees, shipping, fulfilment, payment processing, stock holding, advertising and returns. Good bookkeeping helps sellers understand whether growth is actually producing cash and profit.
What Ecommerce Expenses Can Be Tracked?
Common ecommerce expenses include platform fees, payment processor fees, promoted listings, Amazon advertising, Google Ads, Meta Ads, packaging, shipping labels, courier accounts, storage, FBA fees, software subscriptions, accountancy fees, office costs, bank charges and supplier costs. Exact tax treatment depends on your situation, so keep evidence and ask for personalised advice when needed.
How Do Marketplace Fees Affect Profit?
Marketplace fees can vary by platform, category, fulfilment method, advertising strategy and return rate. A seller can have strong sales but weak profit if fees, advertising and shipping costs are not monitored. Monthly bookkeeping should show fee percentage and contribution margin so sellers can make pricing decisions.
How Should Stock Be Reflected in Bookkeeping?
Stock bookkeeping should help you understand what has been purchased, what remains unsold, what has been sold, and how stock costs affect gross profit. Growing sellers often need a more structured stock process so profit reports do not swing wildly from month to month.

Ecommerce Bookkeeping FAQs UK 2026
What is ecommerce bookkeeping?
Ecommerce bookkeeping is the process of recording and reconciling online sales, refunds, marketplace fees, payment gateway fees, shipping, stock purchases, advertising costs, VAT records and business expenses. It gives sellers accurate records for tax, compliance and profit reporting.
How is ecommerce bookkeeping different from normal bookkeeping?
Normal bookkeeping may focus mainly on bank transactions. Ecommerce bookkeeping also needs marketplace reports, payment gateway reconciliation, settlement deductions, fees, refunds, VAT coding, stock costs and platform-by-platform profit tracking.
Do Amazon, eBay and Shopify deposits count as gross sales?
Usually no. Marketplace deposits are commonly net payouts after deductions. Gross sales, refunds, platform fees, advertising charges, shipping adjustments and reserves should be separated so reports are accurate.
How often should ecommerce bookkeeping be done?
Monthly bookkeeping is recommended for most ecommerce sellers. It keeps marketplace reconciliation, VAT checks, fee tracking, stock records and profit reporting up to date before problems build up.
What records should a UK ecommerce seller keep?
Keep marketplace statements, payment gateway reports, bank statements, supplier invoices, stock purchase records, shipping and courier invoices, advertising receipts, software subscriptions, VAT records if registered, and accounting software reports.
What is marketplace reconciliation?
Marketplace reconciliation means matching platform activity to accounting records and bank deposits. It checks that sales, fees, refunds, reserves, advertising deductions and payouts are recorded correctly.
Why does my Amazon payout not match my Amazon sales?
Amazon payouts can include referral fees, FBA fees, storage fees, refunds, reimbursements, advertising, reserves and other adjustments. These deductions mean the bank deposit will usually differ from gross sales.
Why does my eBay payout not match my eBay sales?
eBay managed payments can include seller fees, promoted listings, refunds, postage labels, holds and other deductions. Bookkeeping should separate these items instead of treating the payout as the full sale.
Why does my Shopify payout not match my Shopify orders?
Shopify payouts may be affected by payment processor fees, refunds, chargebacks, payment timing, Klarna or PayPal payments, manual payments and app charges. Payout matching is needed for accurate books.
What is the VAT registration threshold for UK sellers in 2026?
GOV.UK lists the VAT registration threshold as more than £90,000 of taxable turnover. Sellers should monitor taxable turnover on a rolling 12-month basis and seek advice if they are approaching the threshold.
Do I need Making Tax Digital software for VAT?
VAT-registered businesses generally need to keep digital VAT records and submit VAT Returns using compatible software unless exempt. Ecommerce sellers should ensure their software and records support this process.
Does Making Tax Digital for Income Tax start in 2026?
GOV.UK says Making Tax Digital for Income Tax starts from 6 April 2026 for sole traders and landlords whose total annual income from self-employment and property is over £50,000. Some ecommerce sole traders may be affected.
What Self Assessment dates should ecommerce sellers know?
GOV.UK says you must tell HMRC by 5 October if you need to complete a tax return for the previous year and meet the relevant conditions. For 2025 to 2026 returns, GOV.UK lists 31 October 2026 for paper returns and 31 January 2027 for online returns.
Can I use spreadsheets for ecommerce bookkeeping?
Spreadsheets may be suitable for very small sellers, but they become risky as transaction volume grows. VAT-registered sellers and sellers with multiple platforms usually benefit from accounting software and structured monthly reconciliation.
Which software is best for ecommerce bookkeeping?
The best software depends on your platforms, transaction volume, VAT status and reporting needs. Many UK sellers use Xero or QuickBooks with carefully configured marketplace and payment gateway integrations.
Should I connect marketplace apps to my accounting software?
Apps can save time, but they must be configured properly. Poor setup can duplicate sales, miscode VAT, ignore fees or leave clearing accounts unreconciled. A monthly review is still needed.
How should stock purchases be recorded?
Stock purchases should be tracked in a way that supports gross margin reporting. Depending on your setup, stock may need to be treated differently from ordinary expenses so cost of goods sold is meaningful.
What reports should an ecommerce seller review every month?
Useful monthly reports include profit and loss, balance sheet, cash-flow summary, platform sales, marketplace fees, advertising spend, stock and cost of goods sold, VAT liability if registered, and bank reconciliation reports.
What are common ecommerce bookkeeping mistakes?
Common mistakes include recording deposits as sales, duplicating income, ignoring fees and refunds, leaving payment gateway balances unreconciled, misclassifying stock, missing VAT coding and not reviewing reports monthly.
When should I hire an ecommerce bookkeeper?
Consider hiring specialist support when monthly transactions grow, you sell across multiple platforms, VAT becomes relevant, bookkeeping takes too much time, reports feel unreliable, or you need clearer profit and cash-flow visibility.
