Earned but not invoiced
Completed work or recurring service changes that may not have reached the relevant invoice period.
Billing leakage screening for MSPs
Verify what you have earned.
RevCerta is designed to help managed service providers identify coded billing differences that warrant internal verification, without presenting every difference as lost revenue.
Discuss your billing review requirements. We agree the scope, engagement terms and secure handling arrangements before payment or record transfer.

Where value can slip
Complex service delivery creates quiet billing gaps.
Recurring agreements, projects, service changes and approved exceptions often live across different records. The screening compares coded fields and identifies the evidence your team should verify internally.
Rate and scope differences
Invoice lines that may not reflect agreed pricing, quantities, dates or approved scope changes.
Authorised exceptions
Discounts, credits and non-billable work are separated from genuine review items instead of being counted as leakage.
Review method
A restrained screening process, designed for verification.
After scope and terms are agreed, every coded item will follow defined checks and human review. RevCerta will not auto-confirm leakage, combine currencies or present unverified differences as recovered revenue.
01
Activate controls
Confirm the contracting parties, terms, appropriate data route and operating controls.

05
Return for verification
Provide coded findings and the specific evidence the client should check internally.
Review options
Start with a defined scope.
Discuss your service line, billing period and record counts first. We confirm fit before requesting records.
Initial screening
A no-cost screening of ten agreed, effectively anonymous coded records, one period and one currency. Original documents and the mapping key stay with your team. Results indicate what needs internal verification. No obligation to buy a further review.
Focused Pilot
£350 for one legal entity, one service line, GBP and one monthly billing cycle. All limits apply together: up to five customer accounts and agreements, 25 invoice or credit documents, 250 billing lines, 500 related service/change records, ten amendments, 60 contract pages and ten source files.
PDF findings report, XLSX findings register, a billing-control action list and one written clarification round requested within ten working days of delivery. Seven working days from confirmation of complete agreed records and receipt of £175; the remaining £175 is due within seven calendar days of final delivery. Working days exclude England and Wales bank holidays. Applicable taxes, settlement currency and bank charges are agreed before invoicing.
Agree handling before transfer
The paid scope is separate from the anonymous screening. Any selected evidence extracts or documents require an approved inventory and appropriate confidentiality and handling arrangements first. No system access is requested. The fee covers the review even if no discrepancies are found; recovery is not guaranteed.
Illustrative method

Our example report shows how possible underbilling, valid exceptions and collections matters are separated, with a clear explanation of the evidence your team should verify.
The example uses fictional records and is not a client result.

Differences are not automatically leakage.
Every flagged item must pass approval, billability, billing-trigger and payment-term checks. Unsupported items remain candidates or are excluded; they are never presented as recovered revenue.
- Human-reviewed classifications
- Coded reason and client check for every candidate
- Collections kept separate from leakage
- Client retains every billing decision
