I Learned This the Expensive Way
Second year freelancing. Big project, new client. Sent the invoice with Net 30 because that's what everyone does, right? Day 30 comes. Nothing. Day 45. Nothing. Day 60, I finally call. "Oh, we're on a Net 60 cycle here."
That $4,800 invoice? Didn't hit my account until day 73. Meanwhile, rent was due in Chiang Mai, my credit card was maxed, and I'm doing math on whether I can stretch a bag of rice for two weeks.
Now I know better.net 30 isn't some universal rule. It's what slow-paying clients want you to think is normal. Your payment terms are negotiable. And picking the wrong ones? Creates cash flow problems you don't need to have.
Common Payment Terms Explained
Due on Receipt
Payment expected immediately upon receiving the invoice. Reality is most clients pay within seven to fourteen days. Best for new clients and small projects and retail or consumer services.
Net Seven or Net Ten
Payment due within seven or ten days. Best for ongoing relationships and smaller invoices and service businesses.
Net Fifteen
Payment due within fifteen days. Best for a balanced approach. Reasonable for clients and good for cash flow. Often a good middle ground for freelancers.
Net Thirty
Payment due within thirty days. Best for established relationships and larger companies and B2B standard. Warning that industry default doesn't mean it's right for you.
Net Forty-Five or Net Sixty or Net Ninety
Extended payment windows of forty-five or sixty or ninety days. Best for large enterprises with accounting cycles. Rarely appropriate for freelancers unless compensated.
Net Thirty vs Net Fifteen Comparison
Choosing between Net thirty and Net fifteen significantly impacts your cash flow.
Net Fifteen Advantages
Faster cash flow since money arrives two weeks sooner. Less financing needed reducing need for credit or savings buffer. Better collection rates since shorter terms often mean better payment behavior. Signals professionalism and shows you run a serious business.
Net Thirty Advantages
Client-friendly with more time to process invoices. Industry expectation that's standard in many B2B relationships. Larger projects where it's reasonable for invoices over five thousand dollars. Enterprise clients where some large companies require it.
Real Impact on Cash Flow
With ten thousand dollars in monthly billings.net fifteen means you typically have around five thousand to seventy-five hundred dollars of receivables outstanding.net thirty means you typically have around ten thousand to fifteen thousand outstanding.net sixty means you might have around twenty thousand plus waiting to come in.
The difference compounds when you have multiple clients on different cycles.
When to Use Due on Receipt
Due on Receipt isn't aggressive. It's appropriate for many situations.
Good Candidates for DOR
New clients until they prove reliable payment behavior. One-time projects with no ongoing relationship to maintain. Small invoices under five hundred to one thousand dollars. Consumer clients meaning individuals versus businesses. Rush work when you prioritized their project.
How to Frame It
Don't apologize for DOR terms. Professional language includes payment is due upon receipt of this invoice. Please remit payment within seven days. We accept payment methods and payment is due immediately.
Most clients won't push back. And those who do may be warning signs.
Early Payment Discounts
Early payment discounts incentivize faster payment with a small price reduction.
Common Discount Structures
Two ten Net thirty means two percent discount if paid within ten days otherwise full amount due in thirty. One ten Net thirty means one percent discount for payment within ten days. Three fifteen Net forty-five means three percent discount if paid within fifteen days with full amount in forty-five.
The Math Behind Discounts
A two ten Net thirty discount means clients save two percent by paying twenty days early. Annualized that's roughly two percent divided by twenty days times three sixty-five days equals about thirty-six point five percent annual return.
Clients with strong cash positions should always take this discount. It's better than any investment return. For you it's paying thirty-six percent interest to get cash twenty days early.
When Discounts Make Sense
You need cash urgently but consider if this is a recurring problem. You're working with slow-paying clients who respond to incentives. Your margins are high enough to absorb the discount.
When to Skip Discounts
Your cash flow is healthy. Clients already pay on time. Margins are thin.
Late Payment Fees
Late fees discourage delayed payment and compensate you for the inconvenience.
Standard Late Fee Structures
Percentage-based at one to one point five percent per month or twelve to eighteen percent annually. Flat fee of twenty-five to fifty dollars per late invoice. Combination of flat fee plus percentage for continued lateness.
How to Implement
Check what's legal where your client is. Some US states cap late fees, and the UK and EU already give you statutory interest. State terms clearly on invoices and contracts and statements of work. Get agreement since client should acknowledge terms before work begins. Apply consistently and don't waive for some and not others. Communicate first and send reminder before applying fee.
Sample Language
Payments not received within X days of invoice date are subject to a late fee of one point five percent per month or eighteen percent annually. We reserve the right to suspend work on ongoing projects until outstanding balances are cleared.
The Psychology of Late Fees
The goal isn't to collect late fees. It's to encourage on-time payment. Many freelancers include late fee language but rarely enforce it. The mere presence of the policy improves payment behavior.
What the Law Says (2026)
Payment terms are mostly between you and the client. Mostly. A few places now back freelancers up with actual law.
New York. The Freelance Isn't Free Act went statewide on August 28, 2024. If a client hires you for eight hundred dollars or more, alone or across several projects in a hundred and twenty days, they owe you a written contract. And they have to pay by the date in it, or within thirty days of you finishing if there's no date. The state has a model contract you can use.
UK. Business clients who pay late owe statutory interest of eight percent plus the Bank of England base rate, unless your contract says something else. You can also claim a fixed forty, seventy or a hundred pounds per invoice depending on its size. Details on GOV.UK.
EU. Same idea. Late B2B payment means interest from the day after the due date, plus a flat forty euro fee for each late invoice. Rates change twice a year, so check Your Europe for the current one.
None of this works on consumers. It's business clients only.

How to Communicate Terms
In Your Contract
Payment terms should appear in every contract. Deposit requirements covering amount and when due. Payment schedule for milestones. Final payment terms. Late fee policy. Accepted payment methods. If you take international clients, say which currency and who pays the fees. Our Wise vs PayPal vs Payoneer breakdown shows how fast those fees add up.

On Your Invoice
Clear invoice language. Payment Terms: Net fifteen. Due Date: Specific Date. Please pay by Date. Late fee policy reminder. Payment instructions and methods.
