E-commerce accountants in South Twickenham
If your South Twickenham business sells through marketplaces, your own store or both, the hard part is not the bookkeeping, it is the VAT: when the marketplace accounts for it, when you do, how imports are treated, what happens with EU customers. We handle this for sellers across South West London and the £149 health check finds the errors before HMRC does.

Worth knowing
Rules that come up in this work
Switching accountants
The main reasons people switch accountant are surprise invoices, missed deadlines and not understanding what they are being told. Switching involves a clearance letter between the firms, a transfer of records and agent authorisations, and a short handover of the current position. It takes about two weeks and should cost nothing extra.
Closing a company
Voluntary strike-off is available only to solvent companies. One that owes money it cannot pay needs a creditors' voluntary liquidation through a licensed insolvency practitioner, and directors who dissolve an insolvent company face personal consequences. For a solvent company the process takes three to four months from filing the DS01, with notice to creditors and shareholders within seven days.
Crypto records and reporting
Crypto tax splits into capital gains on disposals and income on rewards, with different rates and different reporting. The £3,000 annual exempt amount and the 18% and 24% rates apply to gains; staking, mining and airdrop income is taxed at marginal income tax rates. HMRC's nudge letters to holders have increased sharply, and a voluntary disclosure before one arrives is treated far more leniently.
The 60-day property CGT return
The 60-day Capital Gains Tax return on residential property is the deadline landlords most often miss, because it falls outside the Self Assessment cycle and runs from completion, not exchange. Private residence relief for periods you lived in the property, plus the final nine months, reduces the gain. Penalties for a late return mirror Self Assessment, starting at £100.
Record keeping
Good records are the difference between a quick enquiry and a long one. For the self-employed, five years after the filing deadline; for companies, six years from the year end; for VAT, six years. Photographs of receipts, PDF statements and software exports all count. The requirement is to keep records, not paper, and a well-organised cloud folder satisfies it.
Allowable expenses
An expense is allowable against trading profit if it is incurred wholly and exclusively for the business. Materials, business travel other than ordinary commuting, a proportion of home running costs, software, insurance, professional fees, bank charges and protective clothing qualify. Client entertainment, ordinary clothing, fines and the private share of mixed-use costs do not.
Employer National Insurance
Since April 2025 employer National Insurance has been 15% on earnings above a £5,000 secondary threshold, a substantial increase for small employers. The Employment Allowance rose to £10,500 at the same time to soften it for the smallest businesses. Directors deciding their own salary weigh this cost against the Corporation Tax deduction a salary provides.
Questions
E-commerce Accountants questions from South Twickenham
Can you handle multiple currencies?
Yes. Sales in foreign currencies are converted at the rate on the transaction date for the accounts and at HMRC's published rates for VAT, and the difference between those and what actually lands in your bank is recorded as exchange gain or loss. The software handles this once configured correctly.
How do refunds and returns affect my VAT and accounts?
A refund reverses the sale and the VAT on it in the period the refund is made, not the original sale. Returned stock goes back into inventory at cost. Marketplace reports show these separately and we reconcile them so that both the VAT return and the profit figure reflect actual net sales.
Do I need to register for VAT if the marketplace collects it?
Marketplace-collected VAT does not count towards your registration threshold, but your other sales do. Many sellers have a mix and cross the £90,000 threshold without realising. We monitor your rolling 12-month taxable turnover monthly and tell you when registration is approaching.
Should I trade as a sole trader or a company?
Many sellers start as sole traders and incorporate as profits grow. A company protects personal assets from supplier and platform disputes, and can be more tax efficient at higher profits, but adds compliance. Marketplaces also treat business accounts differently. We run the comparison for your numbers.
What is the marketplace VAT health check?
A one-off £149 review of your VAT registration, your marketplace tax settings, your treatment of imports and overseas sales, and a sample of recent returns against the rules. It produces a written report of errors found and what to do about them. Most sellers who have set things up themselves have at least one.
Can you reconcile my payment processor as well as the marketplace?
Yes. Card processors and payment gateways on your own store are integrated so that gross sales, fees and payouts post and reconcile automatically. The fee treatment, including VAT on processor fees, is configured at setup, which is where most self-built integrations go wrong.
Do you have an office in South Twickenham?
No. IGI Accounting is an online-only firm. We serve South Twickenham and every other UK postcode remotely, with records sent by WhatsApp or email and everything filed electronically. The absence of local premises is why the fee for e-commerce accountants is the same in South Twickenham as anywhere else in the country, and why there is nothing to visit and nothing to print.
Is e-commerce accountants in South Twickenham really the same price as elsewhere?
Yes. The fee published on this page is what a client in South Twickenham pays and what a client in any other part of England pays. It is confirmed in writing before work starts and the invoice matches the quote. Where a higher package applies because your situation is more complex, we say so at the quote stage, never afterwards.
