ar-credit-control

Run the AR aging sweep workflow, which calls acct_get_aging_report for receivables, buckets invoices into 0-30, 31-60, 61-90, and 90+ day tiers, then assigns each overdue invoice a Reminder, Escalation, or Legal dunning tier sorted by days overdue.

The credit limit review workflow pulls customer profiles via acct_list_contacts and 12 months of sales history via acct_list_sales_invoices, then compares the proposed limit against payment history and aging risk to recommend approve, reduce, or hold with rationale.

It requires the existing acct_* MCP contract tools (acct_list_sales_invoices, acct_get_aging_report, acct_list_contacts), the finance-manager owning profile, and a gbrain finance source containing credit-limit policy and dunning message templates.

Aging bucket drift happens when invoice date is used instead of the contractual due date as day-0. Always age invoices from the due date, and flag partial-payment residuals by outstanding balance rather than original invoice amount.

Do not use it for supplier invoice processing, which belongs to ap-vendor-management, or for bank and gateway settlement, which belongs to bank-payment-reconciliation. It also does not enforce credit limits at order entry; that handoff must be documented separately.
