Medical clinic manager cannot stop paying contractors for repeat repairs covered under guarantee because billing department ignores guarantee terms, leading to double payments for identical issues.

Workarounds Described

• Manager manually notifies billing department about guarantee terms but department ignores the warning
• Billing pays invoices without verifying warranty coverage

Implied Software Gaps

• Automated invoice validation that checks for active warranty/guarantee before payment
• Centralized service history database flagging repeat issues within guarantee period

GuaranteeGuard Invoice Validator

An AP automation add-on that cross-references incoming contractor invoices against a database of prior service calls and their guarantee periods. Flags duplicate/same-issue invoices that fall within an active warranty window, prevents payment without review, and provides audit-ready documentation.
