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
  • A recovery workspace with status, owner, notes, manager summary, and exportable follow-through

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.

How it works

Two exports in. A prioritized fix list out.

Validate the billing gap without an integration project or a spreadsheet rebuild. Leakage Finder compares what you pay for with what your PSA is billing.

Step 1

Upload the two files that should agree

Bring the vendor or distributor export and the PSA billing export your team uses for recurring invoices.

Step 2

See every line that needs attention

Leakage Finder handles naming drift and flags quantity gaps, unbilled items, fuzzy matches, and orphaned records.

Step 3

Review and export the fix list

Prioritize the monthly impact, assign the correction, and verify the gap is closed before invoices go out.
