The field guide · free · no signup

Run a free QC on a real file.

Drop a set of draft financials, a trial balance, or a working paper. Lejjor casts it, ties it back to last year, traces every figure to its source, and flags what it can’t stand behind — then hands you a glass-box report you can read line by line. Nothing is asserted. Nothing is final until a CPA signs.

Drop a file to check it.

PDF, Excel or CSV — draft financials, a trial balance, or a lead schedule. The file stays in your browser; nothing is uploaded, stored, or used to train anything.

What the free QC checks

Five things, out loud.

  • Casts & cross-casts. Every subtotal and total re-added, down and across — so a column that doesn’t foot can’t hide.
  • Prior-year continuity. Opening balances are tied back to last year’s close. A retained-earnings roll-forward that doesn’t reconcile gets surfaced, not smoothed.
  • Every figure traced. Each number is walked back to a source — a bank confirmation, a filed return, a supporting schedule — never asserted on faith.
  • Doubts flagged, not buried. Where the evidence is thin or contradictory, it’s marked for review with the confidence stated plainly.
  • A governance receipt. You get a record of who checked what, at what confidence, and the fact that it’s an unsigned draft until a CPA puts a name to it.
Live example

This is what you get back.

A glass box, not a black box. Watch a governed QC read a set of draft financials — each figure with its badge, the partner who traced it, the reason, and the source. It closes with a receipt and a signature line that stays empty until a human signs.

Read the glass-box report

you

You get the full line-by-line report — every badge, reason and source — plus a governance receipt you can share. It stays an unsigned draft until a CPA signs.

Yours to share
Safe to share

A status you can put your name next to.

The free QC doesn’t hand you a guarantee — it hands you diligence. Every figure traced, every doubt on the record, and a plain statement that nothing is final until a licensed CPA signs. That’s a status you can post to a client or a partner without over-promising, because it describes the work, not a warranty.

It’s the difference between “the AI said it’s fine” and “here’s exactly what was checked, and here’s who signs.” One is a black box. The other you can defend.
