Reconstruction
Most businesses facing an audit don’t have clean books. They have bank statements in one place, receipts in a drawer, exports from a system nobody uses any more and a trail of emails no one has read twice. Jetbooks takes all of it, matches every payment to the invoice behind it, fills the gaps from public records and rebuilds a ledger you can stand behind, every figure traced to the document it came from. Those are the books TaxOS and Protas then work from, so every return starts from accounts that already reconcile. Already running clean books? Run Jetbooks before an audit to find the gaps first.
Two ways in
A one-off job, used at two different moments.
Onboarding
Getting your books in order
For businesses whose records aren’t yet structured enough to run tax operations on.
- Bank statements, receipts and exports in different places
- Gaps from past years, or filings nobody kept
- Once rebuilt, the books load into TaxOS
Health check
Checking books you already run
For enterprises with clean books that want proof before an audit, a financing round or an acquisition.
- Re-runs the reconciliation against source documents
- Flags gaps and entries without evidence
- A findings report before an auditor asks
How it works
Four steps from a drawer of loose records to books that hold up in a forensic review or a tax audit.
Upload bank statements, spreadsheets, scans and exports, or connect by API. Jetbooks takes records in whatever state they are in.
Every payment is matched to its invoice, receipt or contract. Gaps are filled from public records, and anything without evidence is flagged, not guessed.
Jetbooks produces the general ledger, trial balance and statements for each period, every entry traced to the document behind it.
Hand auditors a set of books with an evidence trail behind every figure, ready for a forensic review or a tax audit.
What you get

The outcomes clean books make possible: monthly returns, corporate tax, customs taxes, transfer pricing, audited accounts (soon) and tax audit.
Once rebuilt, the books load into TaxOS, where your team or Protas agents run each outcome.

What is Jetbooks?
Jetbooks is Setoff’s books reconstruction job. It rebuilds incomplete or messy financial records into traced books for tax and forensic audits, and runs as a health check on books you already keep.
Who is Jetbooks for?

What do you need from us?
Whatever records exist: bank statements, spreadsheets, scans, ERP exports or API access. Jetbooks works with records in whatever state they are in.
Our books are already clean. Why use Jetbooks?
As a health check. Run it before a year-end, a tax audit, a financing round or an acquisition to find gaps before someone else does.
What happens after the job?
