Contract modification and proration audit
Examining how upgrades, downgrades, seat changes, and mid-term discounts are priced, invoiced, and recognised.
Proration is where billing applications quietly disagree with the contract. A vendor default of “charge the new price from tomorrow” may not match a term that says “charge the new price from the next anniversary”. Finance often discovers this only when a customer disputes an invoice.
We rebuild a sample of modifications from the contract addendum, through the application event log, to the invoice line and the revenue entry. Differences are classified as customer-facing billing errors or as recognition-only differences.
Where the application cannot be configured to match the terms, we document a compensating calculation that finance can run until the configuration is changed.
Who it is for
Businesses whose subscribers change plans often enough that proration is material to revenue.
Typical fee note
From RM 16,000 when a single proration rule applies. Multiple products with different rules are quoted after scoping. Fees are quoted in writing after scoping. This page is not a checkout.
Scope we usually test
- Proration formulae versus the published terms
- Credit-then-rebill versus net-delta invoicing
- Seat expansions and contractions within a billing period
- Promotional overlays on already-discounted contracts
- Effect of modifications on remaining performance obligations
