The room where the books get handled

Your documents. Your accountant. One place.

Receipts, statements, and invoices stop living in email threads and shoeboxes. They land in a shared room where both of you see the same pile, month by month, until the month is closed.

I run a business

Your receipts, organized and delivered to your accountant.

Snap a photo or drop the file. It lands sorted by month, your accountant sees it instantly, and when everything is in you mark the month ready. No more "did you get my email?"

Set up your room →

Takes about a minute. Works from your phone.

I'm an accountant

Stop chasing shoeboxes.

Every client's documents in one place, organized by month. Ask for what's missing with one click, and see "March is ready" instead of guessing. Your clients get a link that says send your stuff here, from you.

Free for practices. Always.

For your business

The shoebox, retired.

Drop it in

Photo, PDF, or a whole year

Snap the receipt at the counter, drag in a statement, or drop last year's pile all at once. Every document files itself under the month it happened, not the month you found it.

They see it instantly

No email, no chasing

Your accountant sees the same pile the moment it lands. If they need something, a request shows up in your room, and clears the moment you add it.

Close the month

"March is ready"

When everything is in, one tap tells your accountant the month is complete. They review, ask questions right on the document, and close it. Done means done.

New: where your money is going

It reads your receipts. Then it does the math you never get to.

leak

"Insurance is up 45%." A category jumping against its own history, caught the month it happens instead of at tax time.

leak

"This vendor may have charged you twice." Same vendor, same amount, days apart. Two taps to see both receipts side by side.

watch

"A new subscription started three months ago." The charge you forgot you agreed to, still billing. Intentional? Dismiss it. Forgotten? That is money back.

trends

Spend by month, top categories, top vendors, all built from your own receipts. Load last year tonight and the whole picture exists by morning.

Every flag shows its evidence, and you have the last word: confirm what's real, dismiss what's intentional. Nothing is decided for you.

For accountants & bookkeepers

Clients arrive organized.

clients

Every client's room on one screen: documents by month, what came in this week, and which months are ready for you.

requests

"Still need the March bank statement" becomes one click. Your client gets the message, and the month can't be marked ready until it's cleared.

comments

Questions live on the document or the month they're about, not in an inbox. Both of you see the whole thread, in context.

invites

You get a link that says send your stuff here. Your client taps it, their workspace arrives already connected to you, with their details filled in.

findings

SheetTamer flags where each client's money is leaking: category jumps, vendor price creep, duplicate charges. You walk into the monthly call with the talking points already done.

20%

Your practice earns 20% of every subscription payment from clients you introduce, for as long as they stay. Tracked live on your practice screen, paid monthly.

A practice workspace is free, always, with every client and every feature. We never charge for introductions or seats on your side.

Built in: the spreadsheet check

Meet Tally, the most meticulous person in the room.

Most real spreadsheets contain errors, and the ones that slip through rarely stay small. Every workbook in the room can be checked by Tally: totals that no longer foot, tabs that stopped tying to each other, numbers typed over formulas. Deterministic first, plain English always, and every finding traces to a cell.

Try it right now, free, on the spreadsheet you least trust. Your file is checked in memory and never stored; the findings are all we keep. Two checks run free; the deeper three run inside.
