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

We serve Syon remotely by design: records by WhatsApp or email, drafts back for approval, filing electronic. The saving on premises is passed to you in the fee for e-commerce accountants.
A named person handles your e-commerce accountants from Syon and knows the file, so you are not re-explaining your business to a different helpdesk each time.
We explain e-commerce accountants in the words Syon business owners use, not in accountant's shorthand, and we show our working so you can check it.
Nothing is filed for Syon until you have reviewed and approved it. You see the draft, you ask questions, you sign off, then we submit and send you the receipt.

Worth knowing
Rules that come up in this work
Employer National Insurance
The cost of an employee is more than the salary. Employer National Insurance at 15% above £5,000 a year, the 3% minimum pension contribution, holiday pay, equipment and management time all come on top. The Employment Allowance of £10,500 reduces the National Insurance for most employers with more than one person on the payroll.
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
Not every small income needs a tax return. The trading allowance exempts the first £1,000 of self-employment or casual income and the property allowance does the same for rental income, each measured on gross receipts. They cannot be combined with rent-a-room relief on the same income, and claiming the allowance means giving up the expense deduction for that source.
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.
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
Record keeping is a legal obligation with a penalty of up to £3,000 for failure, but its real value is in making every other filing cheaper and more defensible. Keep invoices, receipts, bank statements, mileage logs and any HMRC correspondence, digitally if you like, for five years after the relevant filing deadline for individuals and six years for companies and VAT.
Questions
E-commerce Accountants questions from Syon
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.
What is in the £79 single-channel package?
Monthly bookkeeping reconciled to one marketplace or store's reports, software integration, and the annual accounts and tax return (Corporation Tax for a company or Self Assessment for a sole trader). It is for sellers under the £90,000 VAT threshold; once VAT registration is needed the £129 package applies.
Why does e-commerce bookkeeping cost more than ordinary bookkeeping?
Because a single payout from a marketplace bundles hundreds of sales, fees, refunds, advertising charges and reserves, and each has a different VAT treatment. Reconciling the payout to the underlying report is the job. Our fee is fixed by channels and VAT status rather than by transaction count for exactly this reason.
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 Syon?
No. IGI Accounting is an online-only firm. We serve Syon 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 Syon as anywhere else in the country, and why there is nothing to visit and nothing to print.
Is e-commerce accountants in Syon really the same price as elsewhere?
Yes. The fee published on this page is what a client in Syon 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.
