Plainfield MediaHow to Follow Up on an Overdue Invoice as a Freelancer
Most late invoices are stuck somewhere. One is sitting in an inbox. Another is waiting for a manager to approve it. A third went to someone who doesn't pay the bills. A clear reminder fixes most of them. The rest need a plan, and the sooner you start it, the better your odds.
Set up the invoice to get paid on time
The easiest overdue invoice to collect is the one that never goes overdue. Before you send it, check five things.
- A real due date. Print the date, such as "Due June 15, 2027," and not only "Net 30."
- An invoice number and a one-line description the client's bookkeeper will recognize.
- How to pay. Bank details, a payment link or a mailing address for checks.
- The right recipient. At kickoff, ask who pays invoices and whether they need a purchase order number or a Form W-9 first. Send the invoice to that person and copy your contact.
- Terms agreed in writing. Put the payment terms, and any late fee, in your contract or proposal before the work starts.
A follow-up schedule
There's no official timeline. This is a common one that stays polite and still moves.
| When | What to do |
|---|---|
| 3 days before the due date | Optional heads-up for new clients. Resend the invoice. |
| 1 to 3 days late | First reminder. Short and friendly. |
| 7 days late | Ask for a payment date. Offer to fix anything blocking it. |
| 14 days late | Call. Pause new work if your contract allows it. |
| 30 days late | Final notice with a deadline and the next step you'll take. |
| 45 days and up | Escalate: demand letter, small claims or a collection agency. |
Put every reminder in writing, even after a phone call. Each email should carry the invoice number, the amount, the original due date and the payment details, so nobody has to dig.
Three short emails
1 to 3 days late
Hi Jordan, invoice INV-1014 for $1,600 was due June 15. I've attached it again in case it got buried. Payment details are on the invoice. Thanks!
7 days late
Hi Jordan, following up on INV-1014 for $1,600, due June 15. Can you tell me when it's scheduled to be paid? If something is holding it up, like a missing PO number, let me know and I'll fix it today.
The question "when" asks for a date. It also flushes out the real problem if there is one.
30 days late
Hi Jordan, INV-1014 for $1,600 is now 30 days past due. I sent reminders on June 17 and June 22. Please pay by July 22. If it isn't paid by then, I'll [send a formal demand letter / file in small claims court]. I'd rather settle it simply, and paying the attached invoice does that.
Only name a step you'll actually take.
Pick up the phone
A call at two weeks often solves in five minutes what three emails didn't. You may learn the invoice went to an old address, the client is waiting on its own customer, or your contact left the company. Be friendly and specific. Ask for a date, then confirm it by email.
Offer a payment plan
If the client is short on cash, splitting the balance can beat waiting. Agree on two or three amounts and dates in writing. Send a separate invoice for each part so each one has its own due date.
Late fees
Charge a late fee only if the client agreed to it in writing before the work started. Adding one afterward rarely works and can sour the relationship. States limit interest and late charges in different ways, so check your state's rules before you set a rate.
When reminders don't work
- Demand letter. A formal letter with the amount, the invoice, the reminders you sent and a final deadline. Many small claims courts expect you to ask for payment before you file.
- Small claims court. Dollar limits and filing fees vary by state. Check the court that covers the client's address.
- Collection agency. They usually keep a share of what they recover, so it's a last resort for larger balances.
- Local freelancer laws. Some places have them. In New York City, the Freelance Isn't Free Act requires a written contract for work worth $800 or more, including smaller jobs that add up to $800 in 120 days. If the contract has no payment date, the client must pay within 30 days after you finish the work. Freelancers who aren't paid on time can file a complaint with the city's Department of Consumer and Worker Protection, and a court can award double the unpaid amount.
What an unpaid invoice means for your taxes
Most freelancers use the cash method. IRS Publication 538 says that under the cash method you include income in the year you actually or constructively receive it. An invoice you sent in December 2027 and got paid for in January 2028 counts as 2028 income, unless the money was credited to your account or made available to you in 2027.
The flip side: you generally can't deduct an invoice that never gets paid. IRS Topic 453 says a cash method taxpayer generally can't take a bad debt deduction for unpaid fees, because that money was never included in income. Businesses that use the accrual method follow different rules.
Unpaid invoices also affect your quarterly estimates. Under the cash method, base each estimated payment on money you actually received. Our guide on how to calculate quarterly estimated taxes walks through the math.
Check your list every week
Overdue invoices are easier to collect when you notice them early. Once a week, sort what's unpaid by age: 0 to 30 days, 31 to 60, 61 to 90 and over 90. Send the next message on the schedule for each one. Anything past 60 days gets a call.
Keep every payment in one place
The 2027 Freelancer Client, Invoice & 1099 Tracker marks each invoice Open, Partial, Paid or Overdue, turns overdue rows pink and sorts what's unpaid into 0-30, 31-60, 61-90 and 90+ days. Its Invoice Generator prints a clean invoice from any row. It works in Google Sheets and Excel.
