Accounting Cleanup Software

Accounting cleanup software for messy books

Accounting cleanup software helps you turn scattered, incomplete, or out-of-date financial records into structured, reconciled, reviewable books. ZeroFin is built specifically for this: upload your bank statements, invoices, bills, receipts, and old accounting exports, and it reconstructs the transactions, maps them to a chart of accounts, flags exceptions for review, and produces real financial reports. AI does the heavy lifting; you and your accountant review and approve before anything posts — so the cleaned-up books are ones you can actually trust.

Who it's for

  • Founders whose books are months or years behind
  • Companies preparing for tax season, an audit, or fundraising
  • Accountants and bookkeepers handling client cleanup projects
  • Businesses switching accounting systems and needing a clean opening balance

The problem this solves

Years of backlog

Transactions sit unrecorded across statements, exports, and spreadsheets.

Missing context

You have the numbers but not the story — what each transaction actually was.

Unreconciled accounts

Bank balances don't tie out and nobody's sure which records are right.

A deadline looming

Tax, a raise, or a board meeting is forcing the issue now.

Frequently asked questions

What is accounting cleanup?

Accounting cleanup is the process of gathering scattered records, reconstructing transactions, mapping them to a chart of accounts, reconciling balances, setting opening balances, and producing trusted reports. ZeroFin supports this end to end.

My books are 2 years behind — can ZeroFin help?

Yes. That's exactly the use case. Reconstruction add-ons cover up to 3, 5, or 10 years of history depending on volume.

Do I still need an accountant?

ZeroFin works great with your accountant. AI structures the cleanup; your accountant reviews, approves, and advises — faster than doing it all by hand.

What files can I upload?

Bank statements and exports in PDF, Excel, CSV, JSON, XML, QBO, QBX, and IIF, plus receipts and documents as images.
