Payment Terms by Industry
What's normal in your industry. Net 30, Net 15, due-on-receipt, milestone billing, retainers, factoring — standards vary widely between industries, and using the right pattern for your work is the difference between getting paid in 12 days or 60.
| Industry | Default Term | Distinctive Feature |
|---|---|---|
| Freelance & Creative | Net 15 / Net 30 | 25–50% deposit standard |
| Consulting & Professional Services | Net 30 | 25% retainer + SOW reference |
| Construction & Trades | Milestone billing | Mechanic's lien + retention |
| Manufacturing & Wholesale | Net 30 / Net 60 | 2/10 net 30 discounts |
| Transportation & Logistics | Net 30 | Factoring + quick pay |
| Healthcare Billing | 30–120 days | Insurance adjudication |
| Legal Services | Trust + Net 15 | IOLTA + ABA Model Rules |
| E-commerce & SaaS | Due on receipt | Auto-renewal disclosure |
How to read these guides
Each industry guide answers the same five questions: what's the default payment term, why is it that way, when do you deviate, what are the deposit / milestone / late-fee conventions, and how does this industry differ from adjacent ones. The point isn't to memorize percentages — it's to know what's normal so you can spot when a client is asking for something unusual (in either direction).
Why payment terms vary so much by industry
Payment terms reflect three underlying realities of an industry: how working capital flows, how big a transaction tends to be, and what collection tools exist when something goes wrong. Construction has milestone billing and lien rights because the cost of materials is high and the legal framework gives contractors a forcing function. Trucking has factoring because the cycle from delivery to broker payment is too long for owner-operators to absorb. Legal services have trust accounting because the ABA Model Rules require it. Each industry's payment terms emerged in response to its specific economics; trying to apply freelance Net 15 to a manufacturing wholesale relationship is a category error.
The most common mistakes by industry outsiders
People entering an industry from outside frequently get payment terms wrong in predictable ways. The patterns we see most often:
- Freelancers accepting Net 60 from corporate clients without raising rates to cover the float. The 60-day cycle is roughly an 8% annualized cost on the receivable; not adjusting for it is real margin lost.
- Consultants invoicing without an SOW reference and then wondering why the invoice sat in AP for 3 weeks. The SOW number is what gets the invoice out of manual review.
- New contractors skipping deposits on residential remodel work and trying to recover their material costs from the final payment. When the project goes sideways, they eat $20K+ of materials.
- Manufacturing suppliers under-investing in PO/invoice match accuracy, producing a 30–60% rate of invoices that go to manual AP review. Each manual-review invoice adds a week or more to payment.
- SaaS founders skipping auto-renewal disclosure, which is technically illegal in California (and several other states) and produces chargebacks at 3–5% rates instead of the <1% normal range.
