The product
Your books, running themselves.
Connect once. Every order, fee, refund and payout lands in double-entry books the same day — to audit standard, in pence.
Live books, not quarterly archaeology
Marketplace settlements get split properly — sales, fees, refunds, reserves, advertising — across an ecommerce-specific chart of accounts. Your cash position, real margin and channel P&L are always today's numbers, not three months ago's.
- Settlements reconciled to the penny
- Multi-currency handled natively
- 40+ monitoring rules watching for trouble
Your accountant lives in WhatsApp
Snap a receipt and it files itself — matched to the card payment, VAT reclaimed, stored for seven years. Got a question at 9pm? Ask it where you already are. No portals, no PDFs attached to emails.

Matched to your card payment from today and filed under subsistence. VAT claimed: £6.40.
One tap on the calls only you can make
Most months you'll hear from us a handful of times — only when a transaction genuinely needs the owner's judgment. The AI pre-selects its best answer, you tap to confirm, and a regulated accountant signs off anything with tax consequences. That's the whole job.

How it works
Live in an afternoon.
Connect your channels
Amazon, Shopify, your bank — read-only OAuth, about ten minutes. We pull in up to 24 months of history and build your books from scratch.
We take the books over
Switching accountants is our job, not yours: clearance letter, records, opening balances. From day one your books update daily, automatically.
You answer the odd question
A few one-tap judgment calls a month. VAT, accounts and filings arrive prepared, reviewed and signed by your named accountant.
Why it's different
Software can't sign your accounts. We can.
Every "AI bookkeeping" tool ends the same way: a pile of suggestions you still have to check, and an accountant you still have to hire. Comma is the firm itself. The AI does the work humans shouldn't have to; a named, qualified accountant carries the professional responsibility — reviews the judgment calls, signs the filings, answers for the numbers.
- A named accountant responsible for your engagement
- Every regulated output human-reviewed before filing
- Immutable audit trail on every number in your books
- Professional-body oversight, professional indemnity

FAQ
Fair questions.
Is Comma a real accounting firm?+
Yes. Comma is an accounting practice with a named, qualified accountant responsible for your engagement — not a software tool you operate yourself. AI does the daily work; every regulated output (VAT returns, statutory accounts, tax filings) is reviewed and signed off by a human accountant before it goes anywhere.
Which platforms do you support?+
Amazon (UK/EU/US), Shopify, eBay, Etsy, TikTok Shop, Walmart, Stripe, PayPal and UK bank feeds. Settlements, fees, refunds, reserves and multi-currency are handled properly — not dumped into one lump.
How is this different from Xero plus a bookkeeper?+
Xero gives you software and leaves the work to you. Traditional firms batch your books quarterly. Comma keeps your books current every day, asks you only the questions that genuinely need your judgment (typically a few per month, answerable in one tap), and a regulated accountant signs the output. You get your evenings back and numbers you can actually run the business on.
What does switching from my current accountant involve?+
Almost nothing on your side. You connect your channels and bank, and we handle the professional clearance letter, records transfer and opening balances — switching accountants is a routine, protected process in the UK. Mid-year switches are fine.
Is my data safe?+
Your data lives encrypted in UK/EU data centres, platform connections use read-only OAuth (we never see your passwords), and every change to your books is on an immutable audit trail. We never sell or share your data.
What does the AI actually do — and what does it not do?+
It categorises transactions against an ecommerce-specific chart of accounts, reconciles settlements, matches receipts, watches 40+ monitoring rules (VAT thresholds, deadlines, cash runway, margin shifts) and drafts returns. It does not sign anything, file anything, or make judgment calls that are legally yours or your accountant's — those always go through a human.
Spend your evenings on the business, not the books.
Set-up takes an afternoon. The first month will feel like hiring a finance team.
