Spreadsheet Failure ModeManual Workflow
Root Operational Bottleneck
Early-termination payoffs are computed in a lease-return spreadsheet from a typed remaining-term extract, so the fee billed is not the contract formula.
Control Hazard & Audit Exposure
Contractual termination charges on returned enterprise hardware are under-recovered because the payoff ignored remaining non-cancellable payments.
Deterministic Software ReplacementClient-Owned Architecture
Contract Termination Engine with Instant Payoff and Remaining-Obligation Billing
Termination engine that reads remaining payments and notice terms from the executed schedule and produces the payoff invoice from that formula.
Continuous Assertion Rule
Payoff assertion: a termination invoice must equal remaining non-cancellable consideration under the stored schedule, or a written waiver with an approver is required.
