What RevCerta reviews
RevCerta is designed to screen a small, controlled set of billing records for coded differences that may indicate missed billing, an incomplete billing trigger, an approval issue or a collections matter. It returns a concise list of records for the client to verify internally. It does not make customer contact, change accounting records or declare revenue recoverable.

An illustrative demonstration of the screening method and report structure.
The initial anonymous-screening workbook and the separate paid-pilot scope.
Draft pilot terms, privacy information, security controls and incident procedure.
A process discussion that does not disclose client records, confidential documents or personal data.
Fictional method example
The worked example shows how coded differences become candidates for internal client checks. It is not a client result, independent certification, verified real-world accuracy claim or guarantee of recovery.
RevCerta screens coded fields. The client retains and verifies source documents and controls every billing decision.
Billing field definitions
Work approval records approval of the work. Variance approval records authorisation of a discount or billing difference. Billing trigger describes whether the work is due to be invoiced. Payment due status describes collection timing for an existing invoice. Each field is checked separately.
Two review scopes
The optional initial screening is free and limited to ten effectively anonymous coded records. The separate Focused Pilot costs £350 for the bounded monthly scope described on the main page and in the commercial offer. Its selected evidence is agreed before transfer. Neither service guarantees recovery.
Initial screening workflow
| Stage | Control |
|---|
| 1 Data acceptance | After the contracting party, terms, data route and operating controls are confirmed, accept up to ten effectively anonymous coded records. |
| 2 Boundary check | Reject names, contact details, system identifiers, credentials, links, free text, invoices, contracts and re-identifiable data. |
| 3 Rule screening | Compare coded amounts, work approval, variance approval, billing trigger, billability, invoice, payment due and recurring status. |
| 4 Quality review | Separate candidates, explained items, collections-only items and clear records. |
| 5 Client verification | Return coded findings and the specific evidence the client should check internally. The client decides and acts only after internal verification. |
| 6 Deletion | Follow the agreed retention schedule. Proposed default: delete working copies within 30 days after the final report, or earlier where lawful; record backup expiry and any required retention separately. |
Security and data boundaries
Published examples are illustrative and are not client results. Agree scope, engagement terms and handling arrangements before payment or operational record transfer.
For a live pilot, the client creates neutral codes and keeps the only mapping key inside its organisation.
Transfer uses an agreed restricted-access channel. Access is limited to the minimum people needed for delivery and quality review.
Client information is not used to train public or third-party artificial intelligence systems.
If information may identify a person, processing stops, access is restricted and the client is notified without undue delay.
Security controls reduce risk but do not claim certification or absolute security.
Before an engagement starts
| Required condition | Evidence before transfer |

Service boundaries
RevCerta provides a limited billing screening service. It is not a statutory audit, assurance engagement, legal or tax opinion, penetration test, debt collection service or guarantee of recovery. Findings remain candidates until the client validates the underlying contract, delivery, approval, invoice, credit and payment evidence.
