A collections department is the internal function of a B2B company that manages overdue customer receivables. Typical structure includes credit managers, collectors, dispute resolvers, and cash application specialists. The department's outputs are DSO, CEI, and recovery rates; scaling decisions hinge on ledger size and complexity.
A collections department is the organizational unit within a B2B company responsible for recovering payment from customers who have not paid by the due date. It sits at the intersection of credit management, customer relationship management, and legal escalation. In companies with significant B2B revenue, the collections department is a profit-center function: every percentage point of improvement in Days Sales Outstanding releases working capital equivalent to roughly one day of annual revenue.
| Role | Primary responsibility | Typical ledger size |
|---|---|---|
| Credit Manager | Policy, strategy, escalation decisions, agency placement | Full portfolio oversight |
| Senior Collector | High-value accounts, complex disputes, relationship management | 50–150 accounts |
| Collector | Routine follow-up, demand calls, email campaigns | 150–400 accounts |
| Dispute Resolver | Invoice disputes, deductions, credit note processing | Cross-portfolio |
| Cash Application Specialist | Matching payments to invoices, unallocated cash clearance | Transaction-based |
Days Sales Outstanding (DSO). The average number of days it takes to collect payment after a sale. Calculated as (Accounts Receivable ÷ Total Credit Sales) × Days in Period. A DSO of 45 on 30-day payment terms means most invoices are being collected 15 days late. Industry benchmarks vary: manufacturing 45–65 days, professional services 60–80 days, wholesale distribution 30–45 days.
Collections Effectiveness Index (CEI). A more precise metric than DSO that measures how much of the collectible receivables were actually collected in a period. CEI = (Beginning AR + Credit Sales − Ending Total AR) ÷ (Beginning AR + Credit Sales − Ending Current AR) × 100. A CEI of 95 percent or above indicates a high-performing collections function.
Recovery rate. The percentage of overdue receivables that are ultimately collected (including those handled by external agencies). A recovery rate below 85 percent on the total ledger indicates either a credit quality problem or a collections process failure.
The build-vs-outsource decision hinges on three variables: ledger volume (number of open invoices), average claim value, and debtor concentration. A general framework: under 200 active accounts and average invoice under $5,000 — outsource to agency from the start; 200–500 accounts — hybrid model with internal team and agency partner; over 500 accounts with complex dispute patterns — dedicated internal function with agency support for escalation and cross-border claims.
A collections department manages the recovery of overdue B2B receivables. It contacts customers with unpaid invoices, negotiates payment plans, resolves disputes, escalates to legal counsel or collection agencies when needed, and tracks performance through DSO, CEI, and recovery rate metrics.
Accounts receivable (AR) is the full function of managing money owed to the business, including invoicing, credit limit management, cash application, and reporting. Collections is the subset of AR that deals specifically with overdue accounts — where payment is past due and active recovery work is required.
