From two exports to a review-ready answer in about five minutes.

Follow this path to complete your first MSP billing reconciliation without a demo, call, PSA connection, or configuration project.

Run my first audit See a finished audit

Before you start

One vendor/distributor billing CSV
One PSA recurring-billing CSV
No PSA credentials, integration, or writeback
Three own-data audits free; no credit card

Export the two sides of billing

From the vendor or distributor, export what you are paying for. From the PSA, export what each client is being billed for. Leakage Finder never needs PSA credentials or write access.

Vendor CSV: client, product, quantity
PSA CSV: client, product, quantity; unit price is optional
Repeated client/product lines are consolidated automatically

Upload and confirm the columns

Common headings are detected automatically. If your export uses different names, the mapping screen shows the required field beside a preview of your data so you can select the matching column.

No spreadsheet cleanup is required for familiar columns
Your approved mapping is reused on later audits
A privacy-safe receipt confirms field coverage and row counts
Use the public templates below if you want a known-good format

Review the audit, then act

Start with exact matches, review likely matches with their confidence and normalization trail, then work through unbilled, under-billed, quantity-gap, and orphaned items.

Estimated monthly impact is calculated line by line
Nothing is written back to the PSA automatically
Export the findings and correction plan when review is complete

Known-good files

Start from a template or inspect sample data.

Templates contain headings only. Sample files contain synthetic records so you can inspect the structure without exposing client data.

Troubleshooting

If something looks wrong, check this first.

A required column is missing

Choose the matching heading in the column-mapping panel, or copy the data into one of the templates below.

I want to confirm compatibility without sharing client data

Upload the export and use Copy safe report after it passes. The receipt includes field status, row counts, and PSA price coverage, but excludes the filename, client names, product names, and row values.

The PSA export has no unit price

Leave the optional price mapping blank. Quantity matching still works, and Leakage Finder shows the per-license fallback before you run so you can replace it with your own estimate.

The same customer has different names

Review the suggested fuzzy match. The result shows both raw names, normalized names, and a confidence score before you accept the finding.

A product appears more than once

True duplicate client/product lines are consolidated automatically. Negative vendor quantities are treated as credits or adjustments and netted against the matching positive line. A credit-only item whose net quantity stays negative is rejected so it cannot create a false audit result.

The result shows no leakage

That is a valid result. Check the match-rate and unmatched sections, then save the clean audit as evidence for the billing review.
