E-commerce accountants in Thamesmead
If your Thamesmead 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 East London and the £149 health check finds the errors before HMRC does.

Worth knowing
Rules that come up in this work
Switching accountants
You can switch accountant at any point in the year. The new firm requests clearance and your records from the old one, which cannot withhold your own documents though it may hold its own working papers until its fees are settled. Agent authorisations with HMRC and Companies House are transferred, and the next deadline is picked up without a gap.
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.
Employer National Insurance
Employers pay National Insurance at 15% on each employee's earnings above the £5,000 secondary threshold, following the April 2025 changes. The Employment Allowance offsets up to £10,500 of this for eligible employers, which for a small team often removes the liability entirely, but companies where the director is the only employee do not qualify.
Workplace pensions and auto-enrolment
Auto-enrolment duties begin the day you take on your first employee, not when the Pensions Regulator writes to you. Eligible staff must be enrolled, contributions paid every pay period and re-enrolment carried out every three years. Director-only companies without employment contracts are usually exempt. Fines for non-compliance are fixed and escalating.
Dormant companies
Dormancy is a status that is easy to lose. The strict rule is no accounting transactions other than share capital and Companies House fees, which means no bank account activity at all in practice. Fees should be paid personally by the director. A company that traded and has stopped becomes dormant only after its final trading accounts and tax return are filed and HMRC is told.
The trading and property allowances
The first £1,000 of trading income and, separately, the first £1,000 of property income each year is tax free under the trading and property allowances. Below those figures no return is needed for that income. Above them you can deduct the £1,000 allowance instead of actual expenses if that is better, which suits side businesses and single-room lets with few costs.
Crypto records and reporting
HMRC treats cryptoassets as property. Swapping one token for another, spending crypto or gifting it are all disposals for Capital Gains Tax, and staking and lending rewards are income. Gains are computed under pooling rules with same-day and 30-day matching. From 2026 HMRC receives data from exchanges worldwide under the Cryptoasset Reporting Framework, so unreported activity is increasingly visible.
Questions
E-commerce Accountants questions from Thamesmead
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.
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.
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.
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.
Who accounts for VAT on marketplace sales?
For goods sold to UK consumers through an online marketplace, the marketplace accounts for the VAT if the seller is overseas or the goods are imported in consignments up to £135. A UK seller selling UK-held goods to UK customers accounts for their own VAT. Mixed situations are common and we separate them on every return.
How are imports treated?
Import VAT is charged when goods enter the UK and can be reclaimed as input VAT if you are registered, using postponed VAT accounting so nothing is paid at the border. Customs duty depends on the goods and origin and is a cost, not reclaimable. We make sure the C79 or postponed accounting statements are matched to the return.
Do you have an office in Thamesmead?
No. IGI Accounting is an online-only firm. We serve Thamesmead 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 Thamesmead as anywhere else in the country, and why there is nothing to visit and nothing to print.
Is e-commerce accountants in Thamesmead really the same price as elsewhere?
Yes. The fee published on this page is what a client in Thamesmead 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.
