How it works

Three steps. Nothing to set up first.

01

Drop in whatever you've got.

Bank statements, credit card statements, PayPal, eBay, Stripe, sales reports and expenses, even photos of paper receipts. A whole year at once is perfect. We'll sort out which months are which.

02

Answer a few plain questions.

Not a form. A short stack of index cards, one obvious question each. Most owners are done in one sitting.

03

Get your books done.

A Profit & Loss that's actually yours, ready to send to your accountant with one click.

It learns your way

Every business files things a little differently. FirmSum picks up on yours.

Did your books by hand last year? Send that year too.

FirmSum learns exactly how you file — vendor by vendor, category by category. This year gets done your way from day one.

Teach it your books

Your statements

Your statements are encrypted and only used to build your books. Nothing is sold, nothing is shared.

  • Every automatic decision comes with a plain-English reason, one tap away.
  • Nothing is ever a percentage or a score you have to interpret.
  • You can see, and change, anything the system decided.

Already have an accountant?

Invite them in. Nothing changes for you.

They see everything you see, can re-file anything, and can ask you a question right here instead of by email. When they mark your year done, you’ll know it.
