Not all overdue is overdue: split the ledger before you chase it

Open a client's aged receivables and you get a single confident number: overdue, $412,900. It looks like a to-do list. It reads like one number with one action attached.

It isn't. On a lot of ledgers, particularly in industries that bill progressively, that total is four completely different things sharing one label. Three of them should never receive a chase call. The aged report doesn't distinguish between them, which means somebody has to, and if nobody does, the chasing gets pointed at the wrong invoices.

The four bands

Construction is the clearest example, so start there, then we'll generalise it.

1. Statutory claims. In construction, work is billed progressively and each bill is a progress claim. Frequently that claim is a payment claim under the relevant state Security of Payment Act, which carries a statutory response clock and a fast adjudication path. A chase call into that process isn't just unhelpful, it can interfere with a legal timeline that your client is relying on.
2. Contested amounts. Money that was certified down rather than forgotten. Somebody looked at the claim, disagreed with part of it, and the difference is now sitting in the overdue column. Ringing about it as though it were an oversight tells the customer you haven't read your own file.
3. Retention. A percentage of each payment, commonly 5%, deliberately withheld until practical completion and the end of the defects liability period. This money is not late. Under the contract it is not yet payable at all. It appears overdue only because the invoice date has passed.
4. Ordinary overdue invoices. Work done, invoice issued, terms passed, nobody disputing anything. This is the slice worth working, and on many ledgers nobody has ever separated it out.

This is not just a construction problem

Any industry where work is billed in stages, certified by a third party, or subject to a contractual holdback has some version of the same split. Freight and logistics, labour hire, medical billing, civil and infrastructure, and professional services working to milestones all produce debtor ledgers where a meaningful share of the overdue column is contested, withheld, or procedurally in-flight rather than simply unpaid.

It matters more than it used to, because these are also the industries under the most payment stress. CreditorWatch's May 2026 risk data put late payments at a six-year high, with arrears more than 60 days overdue running at 7.15% in construction and 7.09% in transport, postal and warehousing, against 11.37% in food and beverage services. The sectors with the messiest ledgers are the ones where the chasing matters most.

How to actually do the split

You can't derive this from the accounting data alone, and any tool that claims to classify it automatically is guessing. It takes one conversation with the client, and then it mostly stays true.

• Ask which customers are billed progressively. That one question isolates most of the risk, because statutory claims and retention cluster by customer and contract, not by invoice.
• Ask what retention percentage applies and when it's released. Then treat those amounts as not-yet-due rather than overdue, whatever the report says.
• Ask which invoices are in dispute right now. Your client knows. It is rarely written down anywhere you can read.
• Chase what's left, properly and consistently. The residue is usually a real and worthwhile number, and it is the part that responds to being asked.

We don't publish a figure for how large that residue typically is, because we genuinely don't know yet and neither does anyone else. It varies enormously by contract structure. What we can say is that it is never the whole overdue column, and treating it as though it were is how automated chasing earns a bad name.

What this means for automating the chase

If you're putting any kind of automated chasing over a client's ledger, whether that's email reminders, SMS, or voice calls, the split is the setup work that determines whether it helps or embarrasses you. In Office Voice, that's done with per-customer exclusions and holds: named customers or invoices are taken out of the calling cadence entirely, or paused with a resume date that matches a retention release or an adjudication timeline. They can still receive written contact if that's appropriate, or nothing at all.

The point isn't that the software solves the classification. It's that the classification has to exist somewhere before you switch anything on, and the practice is the only party with enough context to do it.

Once the split is done, the question becomes how to work the chaseable slice without spending your week on the phone. That's AR for accounting and bookkeeping practices, and the sequence itself is in the 60-day chase ladder.
