Payment terms are one of those things freelancers and small business owners often just copy from a template without thinking. Then, three months in, they're chasing late payments and wondering why clients treat their invoices as optional. Your payment terms are not boilerplate — they're a negotiation strategy baked into every invoice you send.
Here's a practical breakdown of the most common options and how to choose the right one for your situation.
What Are Payment Terms?
Payment terms state when payment is due relative to the invoice date. They protect you legally (if a client pays late and you have clear terms, you can charge interest or take action) and set expectations clearly so clients aren't surprised by deadlines.
The format is usually: a short code followed by the number of days. "Net 30" means the full amount is due within 30 calendar days of the invoice date. "2/10 Net 30" means the client gets a 2% discount if they pay within 10 days, otherwise the full amount is due in 30 days.
Net 30: The Corporate Standard
Net 30 is the default payment term for most B2B (business-to-business) transactions. Large companies almost universally expect Net 30 because their internal payment workflows — involving purchase approvals, accounting sign-off, and payment runs — operate on monthly cycles.
When to use Net 30
- Your client is a medium or large company with a formal procurement process
- You're doing repeat work for an established client with a good payment track record
- The invoice amount is large enough that the client needs time to arrange funds internally
- You've agreed on Net 30 in your contract or Statement of Work
The downside of Net 30
For freelancers and small businesses, Net 30 can strain cash flow significantly. If you send a $2,000 invoice today, you won't receive payment for up to 30 days — and in practice, many companies pay on day 28 or 29. If that client pays late (which happens more often than it should), you could be waiting 45-60 days. When you're managing multiple clients and your own bills, that gap matters.
Net 14: The Freelancer's Sweet Spot
Net 14 has become increasingly popular in the freelance community because it's a reasonable compromise. It's short enough that clients feel a sense of urgency, but long enough that it doesn't feel aggressive. In my experience, Net 14 invoices get paid faster than Net 30 without generating more friction or complaints.
When to use Net 14
- You're working with small businesses or startup clients who can pay quickly
- The project is a discrete deliverable rather than ongoing work
- You've completed the work and delivered it — there's no reason to wait a month
Due on Receipt: For Immediate Payment
Due on Receipt means exactly what it says — the client owes the money as soon as they receive the invoice. This is standard for retail transactions and common in certain service industries like consulting, photography, or event work where payment happens at or immediately after the service.
When Due on Receipt works well
- You're dealing with a consumer client (B2C) rather than a business
- You delivered something digital (design files, written content) that the client already has
- You're working with a new client and want to establish strong payment expectations early
- The amount is small enough that immediate payment is completely reasonable
When to be careful
Sending a large invoice due on receipt to a corporate client will often annoy them — their systems simply can't process payments that quickly. Know your audience. For a $50 logo tweak, due on receipt is fine. For a $15,000 software project, Net 30 is the professional choice.
Milestone-Based Payments: The Safest Option for Large Projects
For any project over $1,000, I strongly recommend splitting payment into milestones rather than billing everything at the end. A typical structure looks like this:
- 50% upfront deposit: Required before you begin any work. This covers your time if the client disappears.
- 25% at midpoint: After delivering a significant milestone (wireframes, first draft, etc.)
- 25% on final delivery: Due on Receipt or Net 7, not Net 30
This structure protects you from non-payment, keeps the client invested in the project, and breaks up large amounts into manageable payments for the client. It's a win for everyone.
Late Payment Fees: Should You Include Them?
Late payment fees are both a deterrent and compensation for the real cost of waiting. In many countries (including the UK under the Late Payment of Commercial Debts Act, and most US states), you have a legal right to charge interest on overdue invoices — whether or not you stated it in advance.
I recommend including a clear late fee clause in your invoice notes: "Invoices unpaid after the due date are subject to a 1.5% monthly late payment charge." This isn't aggressive — it's professional. Most B2B clients will see it and make sure to pay on time. Very few will actually trigger the fee.
How to Set Payment Terms Confidently
The biggest mistake freelancers make is treating payment terms as something to apologise for. You're not being demanding by expecting to be paid within 14 days — you're running a professional business. State your terms clearly in your invoice, in your proposal, and in your contract. When clients know the rules before they agree to work with you, there are no surprises.
In Invoice Pro Lab, you can set custom payment terms as free text in the invoice notes section. The due date field automatically signals to the client exactly when payment is expected. The combination of a specific due date plus a written payment terms note is the most effective way to get paid on time.
