When invoice amounts diverge from contracted cloud rates

Contracted cloud rates rarely match the invoice line for line. Usage tiers, currency conversion, taxes, and mid-term seat additions all create legitimate variance. The auditor’s job is to separate those from true overbilling.

We extract unit prices and volume commitments from the contract, then rebuild the expected invoice. Anything unexplained goes into a variance schedule with a confidence note: high confidence for clear rate mismatches, lower confidence when usage data is incomplete.

Clients sometimes discover that an auto-renewal clause locked in a higher tier after a temporary spike. That finding is commercial, not merely accounting—and it belongs in the recovery conversation with the vendor.

Keep the tone factual. Vendors respond better to a clean schedule than to accusations. A well-prepared reconciliation often recovers money and resets the renewal conversation for the next cycle.
