What's a Good Debtor Days Number for an NZ Small Business?
For most NZ small businesses on standard 30-day terms, debtor days of roughly 30–45 is typical and healthy; wholesale and manufacturing businesses on longer trade terms often run closer to 45–60. What matters most is the gap between your number and your stated terms, not the number in isolation.
The Short Answer
Debtor days within about 15 days of your stated payment terms is generally considered healthy. Offer Net 30 and collect around 30–40 days on average, and your accounts receivable is behaving as designed. Offer Net 30 and sit at 55–60, and the number is telling you collection, not the terms themselves, is the problem. See what debtor days are and how to calculate them if you need the formula first.
Why It Varies by Industry
| Business type | Typical debtor days | Why |
|---|---|---|
| Retail / hospitality | 5–15 | Mostly cash or card at point of sale, little trade credit extended |
| Professional services | 30–45 | Standard Net 30 terms, moderate chasing effort |
| Wholesale / distribution | 40–55 | Longer trade terms, statement accounts, larger average invoice values |
| Manufacturing | 45–60 | Longer production and delivery cycles, buyers often on 60-day terms themselves |
| Construction / building supply | 50–65 | Progress payments, retentions, and month-end trading conventions like the 20th of the month following |
A wholesaler sitting at 50 days isn't automatically doing worse than a services business at 35 — they're simply operating on different underlying terms and a different buyer cash-flow cycle.
How Your Payment Terms Affect This Number
The benchmark only means something relative to what you actually offer. A business that moves from Net 30 to Net 60 should expect debtor days to rise by roughly the same amount, with no change in how well it's collecting. Comparing your debtor days against a generic industry figure without accounting for your own terms will consistently mislead you in one direction or the other.
How to Improve Yours
If your debtor days are running well past your stated terms, the fix is usually process rather than chasing harder. See how to reduce debtor days without damaging customer relationships for the specific tactics, ranked by effort.
Frequently Asked Questions
Is there an official NZ benchmark for debtor days?
There's no single authoritative national figure, but accounting platforms including Xero commonly cite 30 days as the standard reference point for a business on Net 30 terms, with actual figures varying significantly by industry as shown above.
What's a bad debtor days number?
As a rule of thumb, debtor days more than 50% above your stated terms (Net 30 running at 45+, for example) is worth investigating. Isolated large or disputed invoices can distort the figure, so check the underlying aging report before assuming a systemic problem.
Should every customer have the same payment terms?
Not necessarily. Many NZ suppliers vary terms by customer risk and relationship length, which is reasonable — just be aware that mixed terms make a single blended debtor days figure harder to interpret without breaking it down by customer segment.
Does a seasonal business need a different benchmark?
Yes. A business with strong seasonal peaks should expect debtor days to fluctuate through the year and compare the same month or quarter year-on-year rather than against an annual average, which can mask a genuine seasonal pattern as a problem.
Stop Measuring Against Terms You're Not Actually Being Paid On
PaidTerms pays you the full invoice upfront, so your own debtor days on that sale are effectively zero — the customer's repayment schedule is between them and PaidTerms.
