ConnectWise or Autotask doesn't match the RMM, which doesn't match IT Glue, which doesn't match what you're billing. We make the stack agree with itself, with drift flagged automatically.

The agreement says 200 endpoints. The RMM sees 217. Nobody knows which is right without an afternoon of checking.
IT Glue describes the client you had a year ago. Techs trust it less every month.
What you invoice is what the PSA thinks, not what's deployed. The gap compounds quietly.
PSA, RMM, documentation, and billing agreeing with each other, drift flagged the day it appears.
Where a vendor integration exists and works, we use it. Where it's a checkbox that half-works, we build the real one. This takes cost out and recovers unbilled endpoints: the stack reconciles itself, and your techs trust the docs again.
A scheduled job compares every source overnight, fixes what has a rule, and files what does not for a person, with the difference already explained. Where it matters we build the checks in too: a daily job that tests the system and flags drift before you find it at month end.
