THE CONTROL GAP“Completed” is a claim.
“Completed” is a claim.
Not evidence.
When a vendor measures the outcome and invoices against its own measurement, finance has no independent answer to one basic question: did the business result actually happen?

HOW IT WORKS
From vendor invoice to verified payable.
Bona sits between the vendor claim and accounts payable. The logic is simple enough to explain in one meeting—and rigorous enough to audit.

EXPOSURE CALCULATOR
How much unverified AI spend could be hiding in your invoices?
This is a scenario calculator—not a savings claim. Use your own assumptions to see why independent reconciliation becomes important as outcome-priced spend scales.
POTENTIAL ANNUAL EXPOSURE$121,680
At 3.9% variance on $260k monthly spend.
See the reconciliation workflow →BUILT AS A FINANCIAL CONTROL
Neutral by architecture.
The same party cannot make the claim, define success, and grade its own work.
Read-only by default
Bona observes authoritative postconditions without modifying operational systems.
Independent evidence
Vendor telemetry is a claim source—not the final authority on whether work succeeded.
Deterministic rules
Approved contract logic produces repeatable verdicts that finance and vendors can inspect.
Tamper-evident receipts
Every verdict preserves source references, timestamps, rule results, and an integrity hash.
No. Billability is decided by deterministic contract rules. AI can help translate contract language into draft rules, but a human approves them before they control a reconciliation.
Bona
Verify the outcome.
Then pay the bill.
