Still Due / Invoice 30 days past due
Thirty days late
Invoice 30 days past due. Polite and firm.
The invoice is a month late. You still want to be paid. Send a complete note: number, due date, 30 days, amount, how to pay. Not a collections desk. Not a legal threat.
Steal this
Subject: Invoice [number] for [Project] is 30 days past due Hi [Client], Invoice [number] for [Project] was due [due date] and is now 30 days past due. Amount due: $[amount]. Please pay by [the original invoice / ACH / the link you already have]. I can resend the invoice if someone else needs it. If a question or a new pay date is in the way, reply this week so I know where this stands. Thank you, [Your name]
Why 30 days is its own note
Thirty days past due is a calendar fact, not a mood. Accounting software flags it. Your own books flag it. Independent designers, developers, and consultants often go quiet here, or jump to language they cannot stand behind. Quiet does not get you paid. A threat is not this product. A complete, polite, firm email is the middle path.
This is not automatically a "last" reminder. Last is a sequence after a first note and a second note. Thirty days is the date. If you already sent a polite first note and a two-week note, this can be the next check-in. If you only sent one earlier note, this can still be the 30-day email. Name the 30 days in the subject so they do not think this is a first ping.
What polite and firm means at 30 days
Firm is not loud. Firm is the facts without padding. Invoice number. Job. Due date. Thirty days late. Amount. How to pay. A door if a question or a new date is in the way. Then you stop.
Polite is not an apology. You delivered the work. Asking to be paid at 30 days is still the job after the job. Do not write "sorry to chase." Do not write "final notice." Do not write courts, liens, credit, collections, or "we will be forced to." That is collections language. You are not a collections agency. Still Due is not a collections agency. This is not legal advice.
What to put in the 30-day email
- Subject with the invoice number and "30 days past due." They should not hunt, and they should not think this is day two.
- The due date, the 30 days, and the amount, exactly as on the invoice. Do not add a late fee you did not agree in writing.
- How to pay, in the same words they already have. New payment paths create new delays.
- A door: resend the invoice, or name a pay date this week. Then stop.
If you already wrote once or twice, you can add those dates in one line. Proof you already asked, not a lecture. If you do not have an invoice number, name the job, the date you sent the bill, and the amount. Attach the invoice again. Accounting is often someone else. A one-page PDF they can forward is more useful than a longer thread.
If they already said "we will pay Friday," do not send this. Confirm Friday in writing and wait. If Friday passes, then send it with the true day count. If they asked a question about the work, answer the question first. A 30-day note on top of an open question reads like you did not read them.
What a 30-day note is not
- "Final notice" dressed as a court or an agency. You are not either.
- Surprise late fees, interest, or "collections will begin." If it was not in the agreement, do not invent it here.
- A CC storm, a public post, or a note to their whole team. Stay in the thread that has the invoice.
- A same-day pile-on after a note you sent yesterday. Give the last note time to land.
If they still do not reply
This page is the 30-day calendar note. It is not the whole cadence. Read invoice follow-up for freelancers for the sequence. If you already sent first and second notes, the last polite reminder is a different email. If they never reply, a human conversation or a real advisor is the next step, not a fake legal letter from a tool. Still Due will not write that letter. Still Due is not a collections agency.
