When to send each reminder
Each tone fits a point in the timeline. The due date options in the generator run from today to 30 days ago, so you can match the message to how late the invoice is.
- Friendly nudge: on the due date or a day or two after. A late invoice is often just a missed one, so start friendly.
- Firm follow-up: inside the first week. It says the invoice is still open and asks when to expect payment.
- Final notice: around two weeks late. It asks for payment or a plan, and says what happens next.
- After the final notice, call: a conversation can settle what a fourth email may not.
What each message says
Every version names the invoice number and the amount and includes the payment link, and all but the final-notice text also name the due date. The client should never have to look anything up to pay.
The friendly email offers to answer questions. The firm follow-up asks the client to say when payment will arrive. The final notice asks them to pay or agree a plan; the email version also says further work pauses until the balance is settled.
Only keep that last line if your contract or terms say work can pause for non-payment. If they do not, take it out before you send.
Before you send it
- Replace [payment link] with the link that opens the invoice and takes payment.
- Check the payment has not already arrived. A reminder for a paid invoice costs more goodwill than a late one.
- Send it to the person who pays the invoices, not only the person you work with.
- Reply in the same email thread as the invoice, so the history is in one place.
Email or SMS
Email suits invoices with several people involved and anything you may need to point back to later; the email version adds a subject line. SMS suits small invoices and clients who already text you, and the SMS versions are shorter. Only text clients who have agreed to get texts from you.
If the invoice still is not paid
Call and ask what is in the way. Offer a payment plan if the amount is the problem, and agree the dates in writing. If your terms include a late fee, work it out and tell the client before you add it. For anything beyond that, get advice from someone qualified where you work.
Payment reminders in Workspace369
Late-payment reminders are on every plan. Workflow automations send them by email on every plan and by text from Voyager, wait between steps, stop when the invoice is paid, and can create a task when it is time to call. Payment plans start on Specialist, and automatic late fees on Commander.
Payment reminder FAQ
How many reminders should I send?
A common rhythm is a friendly nudge before or just after the due date, a firm follow-up inside the first week, and a final notice around two weeks — each shorter and more direct than the last.
Should I include the payment link every time?
Yes. Every extra step between the reminder and paying costs days. Include the same direct payment link in every message, email or SMS.
Is it rude to send a payment reminder on the due date?
No. A short, friendly note on the due date is normal and expected. Keep it to the facts: the invoice, the amount and the link. Save firmer wording for later messages.
What subject line should a payment reminder email have?
Put the invoice number in it so the client can find the invoice. The generator uses “Quick note on invoice [number]” for the friendly nudge, “Invoice [number] — now past due” for the firm follow-up and “Final note on invoice [number]” for the final notice.
Can reminders be automated?
Yes. Workspace369 workflow automations send invoice follow-up emails on every plan, and SMS from Voyager, on a schedule, branch on whether the invoice is still unpaid, and create a task for a person when it is time to call.
