Root Operational Bottleneck
Customer disputes and credit-memo requests are logged in an AR sheet with no owner, no SLA clock, and no link to the invoice they credit, so the same short-pay is re-argued in email every week.
Control Hazard & Audit Exposure
Disputed invoices age past 90 days with no assigned owner; write-offs happen because the credit memo never issued and the audit trail is a cell comment.
Deterministic Software ReplacementClient-Owned Architecture
AR Dispute Case Manager with Integrated Credit-Memo Issuance and Owner SLA
AR dispute case manager that binds each dispute to an invoice, owner, and SLA, and issues the credit memo from the same case when the resolution posts.
Continuous Assertion Rule
Ownership assertion: a dispute cannot remain open past policy days without an assigned owner, and a credit memo cannot issue unless it references the dispute case and the original invoice.
