Why the aging buckets are an input, not an answer
Aging buckets sort balances by how far past due they are. That is a useful shape of the problem — a business with most of its money in 61–90 has a different disease from one with everything in 1–30. But two balances in the same bucket can need completely different treatment.
Before working a list, add three columns to it in your head: how much, why it is unpaid, and whether the customer is reachable. Age plus those three is a priority order.
Triage by cause, because the fix differs
- Never received the invoice — resend and confirm delivery. Cheap and often instant.
- Waiting on paperwork — the customer needs a receipt, a W-9, a lien release or a PO number.
- Disputed — route to whoever owns the scope conversation, not to a collector.
- Forgotten — a reminder works; this is the bulk of most lists.
- Cannot pay right now — negotiate a promise or a schedule and record it.
- Will not pay — escalate as a business decision, with your own advisers.
Concentration and the number nobody looks at
Total outstanding hides how it is distributed. If a single customer is a large share of AR, your exposure is not a receivables problem, it is a customer-risk problem, and the response belongs with whoever sets credit terms and deposit requirements.
Reviewing balance by customer alongside balance by age is the cheapest habit in this whole cluster.
