The accounting tips for startups that matter are the ones a founder can act on this month, and the accounting advice for startups that arrives too late is nearly always the same: the payroll was booked as salaries, the month was never closed, and the runway the board was told was longer than the bank agreed. The habits below fix that. The free payroll for startups calculator on this site does the runway arithmetic, and the rest is a ledger fed from the bank and closed on time.
Separate the money and feed the ledger from the bank
One company bank account, one company card, no founder's personal card for company spend, and accounting software connected to both from the first week. Every transaction then has a place to land and the year-end reconstruction never happens. Categorise weekly; the memory of what a charge was fades in a fortnight.
Book payroll as the loaded cost and close every month
The payroll provider's journal carries the salaries, the employer taxes, the benefits and the fee; book them as separate lines rather than one salary figure, and the burn reads true. Close the month when the bank agrees with the ledger and the payroll and the invoices are in, and do it every month; a closed month is the only kind the board should be shown.
Read the runway from the close, and keep the reading
Cash over net burn, from the closed month's figures, is the runway; it moves with every hire and every dollar of revenue collected. Work it with the calculator on this site and keep each month's reading, which is what Pro does, so the trend is visible before it is a problem. Hand the tax return, the R&D credit and the entity questions to a firm; those are signatures and judgement, not habits.
Questions people ask about accounting tips for startups
What is the single most useful accounting habit for a startup?
Closing the month: bank agreed to the ledger, payroll and invoices in, a profit and loss that is a number. Everything else, including the runway, is read from it.
Should founders do the bookkeeping themselves?
For the first months, with software connected to the bank, yes; hand it to a bookkeeping service when the transactions outrun the founder's evenings, and to a firm for the filings from the first return.
How do I know my runway figure is right?
When it is worked from a closed month's net burn with payroll at the loaded cost and the bank balance on the same date; the calculator on this site takes exactly those inputs.
