THE FINANCIAL CONTROL LAYER FOR

FINANCE PROCUREMENT AI OPERATIONS VENDOR MANAGEMENT

“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?

01VENDOR CLAIM

“82,194 issues resolved”

A successful response or API call is submitted as a billable outcome.

Each claim receives an explainable, contract-based verdict and receipt.

Verified$79,812−$2,382

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.

STEP 01

Ingest the claim

Upload the invoice or connect the vendor’s outcome feed. Every claimed unit gets a stable ID.

Deterministic rules classify every outcome as verified, flagged, pending, or unverifiable.

No escalation No reopen in 72h ×NOT BILLABLE

Every verdict comes with the receipt.

No black-box confidence percentage. Each outcome carries its vendor claim, independent evidence, contract version, rule results, timestamps, and final billability.

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.

At 3.9% variance on $260k monthly spend.

See the reconciliation workflow

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.

Built for the questions finance will ask.

Explore the product

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.

Verify the outcome.
Then pay the bill.
