Microsoft 365 vs HaloPSA for MSP billing reconciliation
Microsoft 365 vs HaloPSA mismatches usually come from a gap between vendor billing and the way recurring services are maintained inside HaloPSA. Leakage Finder compares those exports so MSPs can spot unbilled items, quantity differences, and under-billing before the mismatch turns into normalized revenue leakage.
Why mismatches happen
Where Microsoft 365 and HaloPSA billing drift apart
HaloPSA billing gaps often look small at the row level but show up repeatedly when service names drift, quantities stay stale, or billing updates lag behind licensing changes.
What Leakage Finder surfaces
What the audit actually shows on this comparison
Leakage Finder is useful here because it handles the kind of naming and quantity drift that usually turns HaloPSA billing reviews into spreadsheet cleanup work.
HaloPSA billing rows missing compared with the vendor export.
Seat-count mismatches between Microsoft 365 billing and HaloPSA recurring billing.

FAQ
Why do Microsoft 365 vs HaloPSA mismatches happen in the first place?
They usually appear when Microsoft 365 vendor billing changes before the HaloPSA billing record is updated. Seat adds, SKU renames, client-name drift, and manual billing maintenance all create gaps between what the MSP pays and what the client invoice reflects.
Do I need a direct HaloPSA integration before I can audit billing?
No. Leakage Finder is designed to start with vendor exports and HaloPSA billing exports, which makes it practical for MSPs that want reconciliation results now rather than waiting on a deeper integration project.
What should I do after Leakage Finder flags a mismatch in HaloPSA?
Review the client, product, quantity, and leakage amount, correct the billing record inside HaloPSA, and rerun the comparison so your team has proof that the underbilling or missing billing issue is closed before month-end.
