Debtor management is the end-to-end process of controlling customer credit risk: credit limits, invoicing, dunning, collections, and write-offs. Good debtor management holds days sales outstanding at 45 days or less for B2B trade and captures over 95 percent of receivables within 120 days of invoice.
Debtor management is how a commercial creditor controls the risk and cost of extending payment terms to customers. It covers credit assessment before sale, invoicing and dunning during the credit period, collection when payment is late, and write-off when recovery is exhausted. The core metric is days sales outstanding. The core discipline is disciplined escalation: every account has a clock, every overdue threshold has a defined action, and no overdue invoice waits for someone to remember it.
| Stage | Time window | Primary action | KPI |
|---|---|---|---|
| Credit assessment | Pre-sale | Run the 5 Cs on every new account | 100% credit-checked |
| Invoicing | Day 0 | Issue invoice within 24 hours of fulfilment | First-invoice accuracy >98% |
| Active receivable | Day 1–30 | Monitor; no action unless red flag | Clean aging report |
| Early overdue | Day 31–60 | First reminder, phone follow-up | >70% resolve at this stage |
| Mid overdue | Day 61–90 | Second demand, escalation flag | Dispute rate <5% |
| Late overdue | Day 91–120 | Final demand, pre-legal position | Agency placement trigger |
| Post-agency | Day 121+ | Solicitor referral or write-off | Net recovery >70% of placed value |
A full 5 Cs analysis takes 30 to 90 minutes per new account for a mid-sized B2B credit line. Short-circuiting the process — typically by skipping capacity or collateral analysis — produces the accounts that blow up six months later. Automated credit scoring engines from D&B, Experian, and Equifax compress this to minutes for standard debtor profiles. For high-value accounts above $100,000 in exposure, manual review remains the right approach.
Type 1: Process debtors. The invoice got lost in their accounts payable system, a PO number was wrong, or the approver was on leave. These are the majority of overdue accounts at the 30-45 day mark. A single reminder call that surfaces the process issue resolves them. Resolution rate above 80 percent.
Type 2: Cash-flow debtors. The debtor has the intention to pay but not the immediate liquidity. The correct response is a structured payment plan with defined milestones. Resolution rate 50 to 70 percent on accounts that engage.
Type 3: Dispute debtors. The debtor has a substantive reason to withhold payment: goods defective, service not rendered as specified, an offset claimed. The correct response is dispute escalation to the creditor's commercial team, not collection pressure. A debtor management system that treats all three types the same wastes effort on Type 1 and loses recovery on Type 3.
Disciplined escalation runs on ageing triggers, not on human memory. A workable matrix for B2B trade receivables:
| Age (days past due) | Automatic action | Manual review |
|---|---|---|
| 1–15 | Statement reminder, no action | None |
| 16–30 | Email reminder with ageing notice | None |
| 31–45 | First phone call from credit team | Credit team flags repeat offenders |
| 46–60 | Written demand letter | Credit manager reviews >$10,000 accounts |
| 61–90 | Second demand, interest calculation | Escalation committee reviews >$50,000 accounts |
| 91–120 | Final demand, legal warning | Legal counsel consulted on >$100,000 accounts |
| 121–180 | Placement with collection agency | Credit manager approves placement |
| 180+ | Legal action or write-off decision | CFO approves write-off |
The matrix is declarative. A credit team that operates it does not need to decide, at day 45, what to do with account X. Humans intervene only at defined review thresholds.
Days sales outstanding measures how long on average a receivables dollar takes to collect. Computed as: (Accounts receivable / Total credit sales) × Number of days in the period. A DSO of 45 on 60-day payment terms implies that most invoices are collected within 15 days of due date. Industry-specific DSO benchmarks: industrial manufacturing 45–65 days, professional services 60–80 days, retail wholesale 30–45 days, international B2B export 60–90 days (jurisdiction-dependent).
Across US and UK B2B commercial receivables portfolios reviewed over the last 18 months, the single largest source of avoidable write-offs was the failure to transition accounts from the 90-day to the 120-day escalation band. The pattern: an account enters the 61–90 day band, receives a second demand letter, then loses momentum because the credit controller is chasing other problems. By day 105, the debtor's situation has deteriorated or a tax authority has filed a lien that takes priority over the unsecured trade receivable. Accounts that crossed into the 121–180 day band without a pre-action letter or agency placement had recovery rates of around 30 to 45 percent, compared to 65 to 80 percent for accounts placed by day 120.
Debtor management is the end-to-end process a commercial creditor uses to control credit risk and collect receivables. It covers credit assessment before sale, invoicing, dunning, collection when payment is overdue, and escalation to legal action or write-off when internal recovery exhausts.
Character (reputation and track record), Capacity (ability to pay), Capital (financial cushion), Collateral (security for the debt), and Conditions (external factors affecting the industry). The framework structures pre-sale credit assessment and remains the standard template for B2B credit decisions.
Industry-dependent. Industrial manufacturing typically runs 45 to 65 days, professional services 60 to 80, retail wholesale 30 to 45, international B2B export 60 to 90 days. A DSO materially above the industry benchmark indicates either systemic overdue receivables or an unrealistic payment term offered to customers.
The industry standard threshold is 121 days past due. Earlier placement at 60 to 90 days is appropriate when the debtor has entered a disputed or evasive posture, when the claim is time-sensitive under a statute of limitations, or when industry norms support earlier escalation. Waiting past 180 days materially reduces recovery probability.
An account over 90 days past due is losing value every week. Place a case for a placement assessment within one business day.
