What this audit is showing
Vendor vs PSA comparison
Each row compares the vendor quantity against the PSA quantity actually being billed to the client, which is the gap most MSP teams are trying to prove.
Billing mismatch review with confidence signals
Exact matches clear quickly, fuzzy matches stay visible with confidence context, and unmatched rows stay visible so the team can review them instead of guessing.
Revenue impact visibility
Leakage Finder turns quantity deltas into dollar impact so operators know what to fix first and what may need a client conversation.
Why this is operationally useful
- Vendor vs PSA comparison with exact and fuzzy match status
- Quantity drift, agreement drift, and orphaned recurring items surfaced line by line
- Monthly and annualized dollar impact so the biggest gaps stand out first
- Export-ready findings your billing team can work from without blind writeback
Next step
Run the same check on your own billing data.
Review the flagged rows and confirm which mismatches need human attention.
Correct the billing lines in your PSA, agreement, or recurring invoice records.
Rerun the audit to verify the gap is closed before invoices are finalized.
Need a calmer handoff after the findings? Review the billing correction playbook before you change anything.

How it works
Compare the two exports that never stay aligned for long
The workflow is simple on purpose: upload the files your team already has, let Leakage Finder isolate the gaps, and move from monthly billing hassle to a review-and-approve fix list.
Step 1
Upload the two files that are supposed to agree
Bring in the vendor or distributor export and the PSA billing export your team is actually using to bill recurring work.
Step 2
Leakage Finder shows where things are slipping through
It lines up client and product records, handles naming drift, and flags quantity mismatches, unbilled recurring items, orphaned lines, and agreement drift for review.
Step 3
Review the gaps before the invoice goes out
Get a fix list with client, product, quantity, and dollar impact so the billing team knows what to correct before month-end.
