The back office, run by AI · signed by you
The work disappears.
Who are you here as?
Poof runs the back office: the books, the invoices, the cash plan, the month-end close, and for shops the phone and the field. The AI does all of it up to one line: nothing lands until a person has seen it.


Press the button. Nothing gets written; that is the point.
Step 2 · The inbox
Every entry waits for you, with its reasons.
Approve it, approve part of it, or say why not. Then grant a rule from work you just read, and watch it stop itself the first time you contradict it.
- 08/03 · FERGUSON ENT · job #2026-078$612.40
- 08/09 · FERGUSON ENT · job #2026-081$1,214.60
- 08/14 · FERGUSON ENT · job #2026-083$388.00
- 08/21 · FERGUSON ENT · job #2026-085$1,691.20
- 08/28 · FERGUSON ENT · no job yet$412.00

Step 3 · The reconciliation
One figure. It ties or it doesn't.
Statement ending, less the books at period end, less what is still outstanding. The screen reads it from the server; completion stores the same number; the close reads that. There is no second figure.
| Statement ending balance · Aug 31 | 48,212.19 |
| Less: books at period end | 46,072.19 |
| Unexplained difference | 2,140.00 |
A first reconciliation lists what was still open from before it, never the opening balance, which both sides already agree on. A row you add during the reconciliation counts even though auto-match never saw it. Cleared rows stay cleared when someone later fixes a memo.
Step 4 · The close
The close is a record, and you are the signature.
Seventeen tasks with due dates. Thirteen tick themselves when the books prove them and cannot be ticked by hand; each open one says why in a sentence. The rest are a person's tick, recorded with who and when. This page has been keeping score since you arrived.

Built by a former controller
The person who wrote this signed closes for a living first.
Austin Semple, former controller
Three years as an auditor, then seven as a controller for small businesses, then Poof. He closes his own books on it, from a phone, and fixes what that turns up before anyone else sees it.
Every figure on this page is either a demo, marked as one, or a screenshot of the founder's own books. Prices were checked against QuickBooks on 23 Aug 2026.

What Poof is
The back office, run by AI. Signed by you.
Poof is software that runs the back office for a small business. It keeps the books, sends the invoices, plans the cash, and closes the month — and for service shops it answers the phone, books the job, and carries it out to the truck and back. Every write an AI proposes waits on a card with the evidence it found, and nothing lands until a person has seen it. One plan, every feature, $79 a month.
Run a service shop? Poof for shops adds the phone, the dispatch board, and the technician's field link to the same account.
The rest of the back office
Payroll, sales tax, 1099s, the trucks and what's on them. In the same books.
Each one lands as a card with its evidence, like everything else Poof does, and waits for you.
Rules
Approve it twice, and Poof offers to do it for you.
Approve the same change on a few cards and Poof offers a rule. You say yes, you set its ceiling, and a page shows everything it did on its own, with Undo on each change.
See the featuresPayroll
Your payroll provider pays them. Poof makes the books and the 941 agree.
Forward your provider’s payroll report and it becomes one entry, matched to the bank withdrawals, with wages accrued into the month they were earned and the 941s, W-2s and state returns tied to the pay runs. You turn it on when you’re ready.
See the featuresSales tax
Sales tax by city, exemptions on file, and a return that ties.
Rates by city on every invoice, exempt customers with their certificates, a report by jurisdiction, and the return you file recorded and matched to its payment, so the close ties it out.
See the featuresAssets & loans
The van, its loan and its depreciation, on the books without a spreadsheet.
An asset register with the month’s depreciation approved as one card, loan payments split into principal and interest, and a trade-in (old van out, loan paid off, new van and loan in) as one entry you see before it posts.
See the features1099s
January’s 1099s, prepared from the year’s payments. W-9s collected by link.
Every contractor’s year against the $2,000 threshold, W-9s filled in online, each contractor’s copy and a summary for your CPA, and a checklist for whoever uploads them to the IRS.
See the featuresTruck stock
Count the van from your phone. Poof knows what went on jobs and what went missing.
Each truck is a stock location. Post a count and the parts used on jobs go to those jobs, the rest shows as shrinkage, and the close knows when each van was last counted.
See the featuresThe five-day close guarantee
Closed within five business days of month end, or the next month is free.
The close is a checklist with due dates, and the books tick most of it off themselves. If yours is not ready to sign by the fifth business day, you do not pay for the month after it.
It starts with your first full month. The guarantee covers the first close after a complete calendar month with your bank and card feeds connected, and every month after that. The partial month you joined in is not covered.
Cleanup is a separate job. Historical books that need rebuilding, migrations from another system, and untangling prior months are scoped with you first and have their own timeline. The guarantee applies once the current month is on Poof.
Ready to sign means ready. Feeds reviewed, the bank reconciled to one figure, and every card in Approvals decided by you or a rule you granted. Cards you leave waiting past day five pause the clock, because a close cannot sign around a decision nobody made.
The remedy is the next month free, applied to your subscription, not a refund. If a late close is our fault two months running, you can cancel with the second month refunded.
