Records needed for this question
Dated rate terms, category-level usage and invoice charges.
How to investigate
Recalculate input and output components separately and explain any discounted or cached category.
An illustrative review decision
If cached input receives different treatment from ordinary input, preserve that category through the calculation. Applying the published standard rate to all tokens could create an apparent variance with no billing error.
What can lead to the wrong conclusion?
A blended average can conceal a category error or a legitimate mix change.
The result to retain
A category-by-category calculation with rate provenance.
Apply the review in context
Technology Spend currently provides an evidence-first demo workspace with synthetic demonstration records. Production sources, tenant integrations and external actions remain disabled until explicitly connected and validated. Keep identified, reviewed, approved, implemented and confirmed savings distinct. Capability overlap is a review signal, not an automatic removal recommendation. Production evidence must remain separate from synthetic/demo records.
