Contract amendment file and recurring accounts payable invoice review — "Paying 15% annual indexing price escalators never validated against master service agreement"
Why the manual spreadsheet breaks financial controls and how a deterministic workflow replaces it.
Contract price escalators live in the executed agreement; AP reviews recurring invoices against last month's amount, not the contracted rate.
Annual indexing increases are paid without validation against the master service agreement, compounding overpayment year over year.
Contract rate extraction that stores pricing terms as structured data and validates every recurring invoice line against them.
Rate assertion: invoice unit price must equal the contracted rate for the service period, including any indexed escalator, or the line is held.
Three-stage comparison between manual workbook reconciliation and automated rule-based execution.
Recurring SaaS invoices approved against the prior amount, not the contract.
Escalators are paid without validation against the master service agreement.
Pricing terms stored as data and enforced on every recurring invoice line.
Invoice unit price must equal the contracted rate for the period, including indexed escalators, or the line is held.
