Trust before upload
Built for the moment your billing team needs proof, not another messy system.
MSP billing exports contain sensitive operational data. The site should make the promise feel obvious: validate the leak, keep control of the correction, and talk to the person building the product when something feels unclear.
CSV-first by design
Use the exports your billing team already has. No PSA integration project is required to validate the gap.
No blind writeback
Leakage Finder creates a review queue. Your team decides what gets corrected in the PSA.
Practical data handling
Saved runs are scoped to the signed-in account, and raw CSV upload storage is not the product model.
Founder accountable
The founder chat is not theater. Questions, bugs, and skeptical buyer notes go straight to Dylan.

Find the gap. Assign the fix. Prove the money came back.
Leakage Finder turns every audit into an operating workflow: see what is still at risk, assign the row, record the correction, and carry a clean recovery record into the next billing cycle.
A fix queue, not a report graveyard
Move each gap from needs review to confirmed, corrected, or ignored so follow-through survives past the first audit.
Owner and notes on every row
Keep billing ownership beside the exact client, product, quantity delta, and monthly dollar impact.
Recovered vs still at risk
See what has been recovered this month and what still needs action before invoices are finalized.
Manager-ready close report
Export a recovery report with status, suggested action, owner, and notes for every flagged row.
The free audit proves the problem. The paid workflow helps your team close it, verify it, and stop the same leakage from compounding next month.

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.
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
Export a correction plan with client, product, quantity, dollar impact, suggested action, and owner-ready blanks so billing knows what to fix before month-end.

How we compare
The fastest way to find billing leakage — at a flat price
Most tools make you wire up integrations and then charge you more as you add clients. Leakage Finder takes two CSV exports you already have and shows your exact number in about two minutes — for one flat price that never scales by client count.

Competitor pricing reflects publicly listed information as of July 2026 and may change. Comparison is for general guidance — check each provider for current terms.
Transparent, flat pricing — no per-seat, per-client, or per-integration surprises. Start free, and upgrade only when reconciliation becomes a monthly habit.
