For accounting & tax firms

Every client's file, doc-checked by 9 a.m.

NineSweep works your doc portal and inbox overnight — read-only — checks what's in, what's missing, and who's actually ready to prep, then hands you a verdict table with a chase email drafted for every gap. Drafted, never sent. You make the calls.

Not ready to share logins? Email one drafted return plus its source docs and get a tie-out table back.

We do the legwork. You make the call.

You point NineSweep at the list

The extension list, this week's onboarding, the whole backlog — every client whose file someone would otherwise check by hand.

2:17 AM

It does the legwork

Signs in read-only, works TaxDome, Canopy, ShareFile, and the inbox doc by doc, and reconciles what arrived against each client's checklist.

8:47 AM

Verdicts, with receipts

Who's ready to prep, who's missing what, and a drafted chase email per gap — each row citing the doc it found or the one it didn't.

9:00 AMYou make the calls.

Built for owners burned by “AI”

Trust is the product.

Read-only by design

Nothing in your systems changes. NineSweep gathers and judges; anything outgoing — an email, a submission — is drafted for your signature, never sent.

Verdicts with evidence

No chatbot prose. Every recommendation is a row in a table, and every row cites the documents and portal screens it was read from.

Correct it once

When a judgment call is off, say so in plain English. NineSweep revises its own playbook, re-decides the case, and never makes that mistake again.

“But our rules are special.”

Good. Teach it yours — in a sentence.

Your quirks, your carve-outs, your definition of “worth a second look” — typed as feedback, kept forever, applied to every run after. No tickets, no retraining projects. Watch:

See it on your own files first

Email one drafted return plus the source docs behind it. You'll get back a tie-out table — every number traced to its W-2, 1099, or K-1, discrepancies over threshold flagged, release or hold. No system access, no setup.

From the founder
“NineSweep grew out of production agent automation for university ERP workflows — the same gather-across-screens, judge-by-the-rules work an agency runs every renewal cycle. I build it, I run your pilot personally, and every verdict shows its work. If it can't earn your trust on your own book, it shouldn't have it.”
