The bank account is the bookkeeping.
Open the company's account before the first sale, and pay every company cost from it.
Read the full explanation
Every founder who ends up with expensive books did the same thing: paid for the company from a personal card for six months and then tried to reconstruct it. Open the company's account before the first sale, pay every company cost from it, and pay yourself by recorded distribution. Form 5472 then writes itself, the liability protection holds, and the accountant's bill is small.
So the books start at the bank. Mercury and Wise are connected with a token you create in their settings and mark read-only, and Stripe with a restricted key that can only read the balance; each can list movements and cannot move money, and we read them once a day. With Stripe in the books at gross, a payout is the transfer it is, and revenue is counted once, at what the customer paid. Any other bank, including Relay, is a statement you export and drop in, with the same row never counted twice.
Mercury. A token you create in its settings and mark read-only.
Stripe. A restricted key that can only read the balance and movements.
Wise. A read-only token, the same as Mercury's.
Any other bank. Export the CSV or PDF statement and drop it in.
Categorised as it arrives, corrected once.
What happens to a movement between the bank and the year-end pack, read like a ledger.
- Nineteen headingsRevenue, interest, refunds; software, contractors, advertising, processing, bank fees, the state, taxes, shipping, inventory, travel, equipment, other. And three that are neither income nor expense.
- Not forty
- An owner's moneyA deposit from you is a contribution, not revenue; a payment to you is a draw, not an expense; a move to savings is a transfer. This is the error Form 5472 exists to catch, and the books do not make it.
- Kept apart
- A correctionChange Figma from Other to Software once and every Figma movement, past and future, follows. Rules are yours, per company.
- Remembered
- A doubtWhen nothing fits, the movement waits under Needs a category rather than being filed somewhere wrong and quiet.
- Left for you
- Year endOn Operate, a year-end pack: income and expenses by heading, the owner's movements set aside, every line listed. What your accountant and Form 5472 work from.
- Packed
- Your accountantEvery movement with its category, signed, money in and money out in separate columns. Any plan, any time, any accounting software.

No. It is bookkeeping: the record of every movement in the company's accounts, categorised and kept current. Accounting is what your accountant does with that record: the return in your country, any US filing beyond Form 5472, and advice. The books are built so that work is short.
Mercury, Stripe and Wise by read-only token, on every plan. Any other bank, including Relay, by statement import: export the CSV or PDF from the bank and drop it in, and the same row is never counted twice.
The token you create at Mercury or Wise is marked read-only in their settings, and the Stripe key is restricted to reading the balance and movements. None of them can move money. We store them encrypted, read them for minutes a day, and deleting the token at the provider ends the feed at once.
Yes, and it is at its easiest now. Form 5472 reports what moved between you and the company even in a year with no revenue: the money you put in, the fees you paid, anything you took out. A record that starts on day one is a short job at year end; one reconstructed from a personal card is the expensive kind.
Every movement is given one of nineteen headings as it arrives, with your own money kept apart from revenue and expenses. Correct one and the rule is remembered for every movement from that counterparty, past and future. Anything uncertain waits under Needs a category rather than being filed wrong. It is included on Operate, and quoted on Launch.
Yes, on any plan. Export a CSV at any time: every movement with its date, counterparty, category and sign, money in and money out in separate columns. It opens in any accounting software, and on Operate the year-end pack goes with it.
