Freelance Payment Terms: Net 15 vs. Net 30 vs. Net 60 (What to Put in Your Contract)

Net 15, Net 30, and Net 60 are the three most common payment terms in freelance contracts. Here's the short answer: use Net 15 for new clients and small projects, Net 30 for established relationships and larger invoices, and avoid Net 60 unless you have a signed contract with late-fee protections in place.

Your payment terms are the single most important financial clause in your contract. Get them wrong, and you're effectively giving the client an interest-free loan. Get them right, and you maintain cash flow without straining the relationship.

This guide breaks down exactly what each term means, which one you should use, and how to write it into your freelance contract so you actually get paid on time.

What Do Net 15, Net 30, and Net 60 Actually Mean?

Payment terms define the number of days a client has to pay an invoice after you send it.

Term	Days to Pay	Best For	Risk Level
Net 15	15 days	New clients, small projects, freelancers with thin cash flow	Low
Net 30	30 days	Established clients, monthly retainers, mid-sized projects	Medium
Net 60	60 days	Large enterprise clients, agencies, long-term contracts	High

The clock starts on the invoice date — not when the client approves the invoice, not when they receive it, and not when they feel like paying. Your contract should state this explicitly.

Which Payment Term Should Freelancers Use?

Start with Net 15 for new clients

When you haven't worked with someone before, you have no data on their payment behavior. Net 15 limits your exposure. If they pay late, you find out in two weeks, not two months.

Pro tip: Require a 50% deposit upfront and Net 15 on the balance. This covers your time and materials even if the client drags their feet on the final payment.

Use Net 30 for repeat clients who pay on time

After a client has paid 3-4 invoices on Net 15 without issue, you can offer Net 30 as a relationship-builder. It signals trust. But keep the deposit structure in place for projects over $1,000.

Avoid Net 60 unless you have leverage

Net 60 is standard in agency work and enterprise contracts where the client's own accounting department processes payments on a fixed cycle. If you accept Net 60, your contract must include:

• A late-fee clause (1.5% monthly is standard)
• A suspension-of-work clause for non-payment
• Clear invoice submission requirements so they can't claim they "never got it"

How to Write Payment Terms Into Your Freelance Contract

A vague "payment within 30 days" won't hold up when the client claims they thought the clock started on their approval. Your contract needs specifics.

What a strong payment terms clause looks like

Invoicing and Payment. Contractor shall submit invoices upon completion of each milestone or monthly, as applicable. Client shall pay all undisputed amounts within fifteen (15) days of the invoice date ("Net 15"). Payment shall be made by [bank transfer / credit card / check]. Late payments shall accrue interest at the rate of 1.5% per month or the maximum rate allowed by law, whichever is less. If Client fails to make payment within five (5) days of the due date, Contractor may suspend work until payment is received in full.

Key elements to include

• The trigger date — "invoice date," not "receipt" or "approval"
• Payment method — specify wire, ACH, credit card, or check
• Late fee — 1.5% monthly is standard and enforceable in most states
• Work suspension right — your right to stop work if they don't pay
• Dispute process — they must notify you in writing within 5 days if they dispute an invoice

Common Payment Term Mistakes Freelancers Make

Mistake 1: Using "Upon Receipt" without a definition

"Payment due upon receipt" sounds strict, but it's legally ambiguous. Does "receipt" mean when they open the email? When the invoice hits their inbox? When their accounting team processes it?

Fix: Use Net 15 with a specific trigger date, or use "Payment due within 15 days of invoice date."

Mistake 2: No late fee clause

Without a late fee, there's no financial consequence for late payment. The client's accounts payable department will prioritize vendors who charge interest over those who don't.

Fix: Add a 1.5% monthly late fee. Check your state's usury laws — most allow 1.5% (18% APR), but a few cap it lower.

Mistake 3: Accepting Net 60 without milestone payments

If you agree to Net 60, you might not see a dime for two months. On a $10,000 project, that's two months of unpaid work.

Fix: Break the project into milestones with separate invoices. Invoice 50% upfront, 25% at midpoint (Net 15), and 25% at delivery (Net 15). The overall contract can still be Net 60 on the final balance if needed.

Mistake 4: Not defining "undisputed"

Clients sometimes dispute an entire invoice over a small issue to delay payment.

Fix: Require the client to pay the undisputed portion of any invoice within the payment term. Disputed amounts get resolved separately. This prevents them from holding your entire invoice hostage over a $50 revision.

What Happens When a Client Doesn't Pay?

Your payment terms are only as good as your enforcement plan. Here's the sequence:

1. Day 1 past due — Send a friendly reminder. Use a late payment reminder email template that references the contract terms.
2. Day 7 past due — Send a firmer notice with the late fee amount calculated.
3. Day 15 past due — Send a formal notice of work suspension (if your contract includes this right).
4. Day 30 past due — Send a final demand letter and consider small claims court.

Your contract should also include a termination clause that lets you end the relationship if the client fails to pay within a reasonable period.

How Payment Terms Interact with Other Contract Clauses

Your payment terms don't exist in a vacuum. They work alongside other clauses in your contract.

Scope creep — If you don't have a scope clause, the client can keep adding work while your payment terms stay fixed. See our guide on freelance scope creep prevention.

Work ownership — Your contract should state that you retain ownership of the work until payment is received in full. This is called a "security interest" or "revenue interest" clause. Read more in how to copyright your freelance work.

Late fees — Some states cap late fees. Check your local laws. If you're unsure, use 1.5% monthly — it's enforceable in most jurisdictions and matches what credit card companies charge.

Quick Reference: Payment Term Decision Flow

• New client, project under $2,000 → 50% deposit + Net 15 on balance
• New client, project over $2,000 → 33% deposit + milestone payments + Net 15 per milestone
• Repeat client, good payment history → Net 30, consider keeping deposit for projects over $5,000
• Enterprise client with 60-day payment cycle → Net 60, but require milestone billing and a signed contract with late fees and suspension rights

The Bottom Line

Your payment terms are a negotiation tool, not a fixed rule. Start conservative (Net 15 + deposit) and loosen terms as trust builds. But always put the terms in writing — a verbal agreement on payment timing is just a handshake deal waiting to backfire.

Every freelance contract needs clear, specific payment terms. Without them, you're relying on the client's goodwill — and goodwill doesn't pay your rent.
