Freelance Invoicing: How to Get Paid On Time (and What to Do When You Aren't)

Doing great work is only half the job. Getting paid for it, on time, is the other half. Late payments are one of the most common problems freelancers report, and they ripple into everything else: you cannot pay your own bills or estimated taxes with money that has not arrived. Most payment problems can be prevented with clear terms and a consistent process.

Start before the work: terms in writing

Payment problems often begin with vague agreements. Before you start, put these in your contract or statement of work:

Price and what it covers, including the number of revisions.
Payment schedule: deposit, milestones, final payment.
Payment terms, such as "due within 15 days of invoice."
Accepted payment methods.
Late fee policy, if you have one.
Who approves invoices and where to send them (many companies have an accounts payable inbox and require a purchase order number).

See our guide to freelance contract essentials for the rest of the clauses worth including.

Ask for a deposit

A deposit of 25% to 50% before work begins is common for project work. It filters out clients who are not serious, covers your early time, and makes it much less likely you will be left with nothing. For long projects, use milestone payments tied to deliverables. For ongoing work, a monthly retainer billed in advance is ideal.

What to put on every invoice

Your name or business name, address and contact email.
The client's legal name and billing contact.
A unique invoice number and the invoice date.
The client's purchase order number, if they use one.
A clear description of the work and the period it covers.
Quantity, rate and amount for each line, plus the total due.
The due date (an actual date, not just "Net 30").
Payment instructions and accepted methods.
Your late-fee terms, if any, matching your contract.

Clients will usually ask for a Form W-9 before paying you the first time. Send it with your first invoice to avoid delays.

Payment terms that work

Shorter is better. Net 7 or Net 15 terms get paid faster than Net 30 or Net 60. Large companies may insist on longer terms; price that into your rate.
Make paying easy. Offer bank transfer and at least one card or online option. Processing fees are deductible, and faster cash is often worth the cost.
Invoice immediately. Send the invoice the day you deliver, not at the end of the month.

Late fees

A late fee, for example 1.5% per month on overdue balances or a flat fee, encourages prompt payment. To be enforceable it should be agreed in the contract before work begins, and it must comply with your state's limits on interest and fees. Many freelancers use the late-fee clause mostly as a deterrent and waive it for good clients who pay a little late once.

A polite follow-up sequence

3 days before the due date: a friendly reminder with the invoice attached.
On the due date: "Just a reminder that invoice #1042 is due today."
7 days late: ask whether there is a problem with the invoice and who in accounts payable you should contact.
14–30 days late: a firmer email referencing the contract terms and any late fee, and a phone call.
30+ days late: pause further work until the account is current, and send a formal final notice with a deadline.

Keep messages factual and professional. Many late payments are simply lost invoices or an unfamiliar approval process, and a quick call solves them.

When a client still won't pay

Negotiate a payment plan if the client has cash-flow trouble; get it in writing.
Send a demand letter, either yourself or through an attorney. A letter on legal letterhead often prompts payment.
Small claims court handles disputes up to a limit that varies by state. You usually do not need a lawyer, and filing fees are modest.
Collection agencies typically keep a percentage of what they recover.
Freelancer payment protection laws: some cities and states, including New York State and New York City, have laws that require written contracts and timely payment for freelancers and give them a way to file complaints. Check whether your location has one.

A note on bad debts and taxes

If you use cash-basis accounting, as most freelancers do, you never reported unpaid invoices as income, so there is no bad-debt deduction for your unpaid fees. The upside is that you do not pay tax on money you never received.

Bottom line

Get terms in writing, take a deposit, invoice immediately with a clear due date, and follow up on a schedule. Those four habits prevent most late payments, and the rest can usually be resolved with a firm, polite process.
