Net-30 Invoice Still Unpaid: Free Follow-Up Email

Net-30 means payment is due 30 days after the invoice date. When that window closes with no payment and no reply, send a short, dated follow-up that restates the terms, attaches the invoice again, and asks for one payment date.

Free template: net-30 just expired

Send this on day 31 (or the first business day after), not weeks later. Replace every [bracket] before sending.

Hi [Client Name],

Invoice [Invoice #] for [Amount] ([Project / Deliverable]) was issued on [Invoice Date] with Net-30 terms, so it was due [Due Date]. I have not received payment yet.

Could you confirm the date payment will go out? If anything on the invoice needs correcting, or it should go to a different contact, tell me and I will fix it today.

Pay here: [Payment Link]
Invoice attached again.

Thanks,
[Your Name]
[Your Business]

Naming “Net-30” and the original invoice date makes the ask factual, not emotional. One clear question beats a paragraph of frustration.

What to check first

• Confirm the invoice date and that Net-30 (or Net-15 / Net-45) is what you actually agreed to in the quote or contract.
• Verify the email reached the right person—many freelancers invoice a project contact while payment sits with AP.
• Resend the PDF and payment link; attachments get stripped more often than clients admit.
• If they already promised a date that slipped, ask for the new date and a transaction reference instead of restarting from zero.

Timing after Net-30

1. Day 31: this email—facts, attachment, one payment date.
2. ~7 days later: a second reminder that cites this send date if still silent.
3. ~14–30 days late: move to a firmer past-due or 30-days-overdue script, then a final notice if needed.

Space messages a few business days apart. Log each send. Escalate specificity, not volume.

What not to do

• Do not add late fees unless your written agreement already allows them.
• Do not threaten collections or small claims in the first Net-30 follow-up.
• Do not bury the due date or payment link in a long story about cash flow.
• Do not keep delivering new work on credit if your contract lets you pause—decide deliberately.
