One ledger, every channel
Whether you sell on Amazon, eBay, Etsy, Shopify, TikTok Shop or all of them, the accounts should show each channel's revenue, fees and margin separately and then total cleanly. That comparison is what tells you where to put the next thousand pounds of stock or advertising.
The compliance calendar
Quarterly VAT under Making Tax Digital, monthly payroll RTI submissions if you pay yourself, an annual confirmation statement, accounts nine months after your year end, and corporation tax payable nine months and a day after it. We run the calendar; you get reminders well before anything is due.
Free basic advice, quoted technical work
Ask us whether a cost is deductible, whether to register for VAT or how to pay yourself, and there is no charge. Anything technical, such as an overseas registration or a restructuring, is priced before we start so there are no surprise invoices.
Before you act
Rates, thresholds and deadlines quoted here reflect the current UK position and current HMRC and Companies House guidance. Check GOV.UK, or ask us, before relying on them for your own business.

Frequently asked
Accountant for online sellers: questions directors ask
I sell on three platforms. Is that extra?
There is a small increment per channel because each needs reconciling, and it is in your quote up front.
Can you sort out a messy previous year?
Yes. Clean up is quoted separately from the monthly fee.
Do you work with sole traders?
Yes, though most of our online sellers trade through limited companies.
How should marketplace payouts be reconciled for accountant for online sellers?
Start with gross orders and reconcile through refunds, marketplace taxes, selling fees, advertising, fulfilment charges, reserves and currency differences to the net bank deposit. The settlement report, not the bank receipt alone, is the accounting source.
How do marketplace fees affect profit for accountant for online sellers?
Selling, payment, fulfilment and advertising fees should be separated so contribution margin is visible by channel. This helps distinguish high revenue from profitable revenue and supports better pricing, stock and advertising decisions.

Keep bank statements, sales and platform reports, purchase invoices, payroll records, VAT workings, finance agreements and Companies House correspondence. We confirm the exact list at onboarding and identify gaps before a filing deadline becomes urgent.
How much does help with accountant for online sellers cost?
The fee depends on transaction volume, record quality, VAT and payroll requirements, historic catch-up and the level of reporting needed. We agree a fixed scope and price before technical work starts, with published packages available on our fees page.
Can you take over accountant for online sellers from another accountant?
Yes. We request professional clearance, collect the prior records and authorities, check the next Companies House and HMRC deadlines, and give you one clear handover list. The process is normally completed remotely.

Yes. We work through secure cloud records, scheduled reviews and digital approvals, while keeping a named team available by phone, video call and email. Clients can also visit our Morden office by appointment.

We regularly work with Xero, QuickBooks, FreeAgent, Sage and connected sales or expense apps. The right setup depends on transaction volume, integrations and the reports you need, not simply the software brand.

What Our Clients Say
“I've been working with Accotax since January 2024, and their support has grown alongside my business needs. My personal allocated manager, Umer, provides tailored services for both of my companies, adapting as I expand and ensuring everything runs smoothly. They are responsive, knowledgeable, and always clear in their communication. Their help with accounts, VAT, payrolls, pensions and compliance gives me real confidence and peace of mind.”
“We worked with a few different accountants before finally settling with Accotax, and we're really glad we did. They take the time to understand how our business works and what our needs are. Anum, who looks after our account on a day-to-day basis, including reconciling invoices and preparing the annual accounts, is amazing, professional, efficient, and follows the processes we have put in place together. Accotax has made our accounting experience much smoother and easier. We see them as a long-term partner as our business continues to grow. I would 100% recommend them.”
“Accotax have been our accountants for many years now. We maintained them because of their professionalism. In the last couple of years I have been working with Imran, who has been very professional and helpful in guiding us through the whole process, explaining and clarifying every aspect of it. Very prompt in responding to questions and patient with us even when we seem to be slow.”
