Watch Fintra verify a real payroll — line by line.
Hand Fintra a completed payroll and it independently recomputes every figure from source, flags each discrepancy with its cause and the exact rule it applied, and seals the result as a tamper-evident evidence package. Everything below is the actual output of that engine — not a mockup, not a slide.
Representative, deterministic dataset for demonstration — not a customer’s data. The same engine runs on your own prior payroll.
The same payroll with a few prior-provider mistakes seeded in. Watch Fintra catch and explain each one.
The payroll, as submitted
What the prior provider reported. Fintra treats none of it as ground truth — it rebuilds every number itself.

Fintra recomputes every figure from source
Independently, using published, versioned tax rules — 246 lines across 20 employees. It never trusts the provider’s number; it derives its own and compares.

Deterministic and tamper-evident: run the same payroll through the same rule-sets and you get the identical package hash — anyone can reproduce it. Alter a single cent in any figure and the package’s ownverify()returns false. Every paycheck also carries its own hash, independent of the roll-up.
What this proves
Every number here came out of the verification engine on a real run — reports, hashes, and all.
Fintra derives each figure from source with published, versioned rules; it never trusts the provider’s value.
All 7 findings are places the prior provider’s number was wrong, each with a cause and the rule it broke.
Every cent of difference is accounted for; nothing is left as an open question.
The whole result is hashed; the same inputs always seal to the same hash, and changing anything breaks it. An auditor can re-run it and get the same package.
Point it at your last real payroll (import by CSV today) and it produces this same package for you.
Honest scope: the dataset above is a representative, deterministic demonstration — not a customer’s payroll. Today Fintra verifies payroll you run on your existing provider (Gusto, ADP, QuickBooks Payroll, Rippling, Paychex), importing by CSV; native Fintra payroll is in controlled development (Texas first). Verification complements your provider and your auditor; it does not file taxes or move money.
Bring your last payroll. We’ll verify it.
Send us a recent pay run and we’ll return this exact package — the reconciliation, the findings, and the sealed evidence — for your own numbers.
