Every invoice has an expiration date. What happens as that date approaches depends on your plan.
Expiration applies to every plan
Every invoice gets an expiration date — 30 days after sending, by default, though you can set your own when creating it. If that date passes without payment, the invoice’s status automatically changes to Expired. This applies on Free, Solo, and Team alike.
Automatic reminder emails — Solo and Team
On Solo and Team plans, SimplePayment can automatically email your client before an invoice expires, on a schedule you set (for example, 7, 3, and 1 days before expiration). You can adjust this schedule under Settings → Invoices.
The Free plan doesn’t include automatic reminders — Free-plan invoices still expire on schedule, but no reminder email is sent automatically.
What happens after expiration
An expired invoice can no longer be paid through its original link. It stays visible in your invoice list with an Expired status, and you can still reference it if you follow up with your client manually.
Important behavior and limitations
- Automatic reminders only apply to invoices in sent or opened status — not drafts.
- Expiration and reminders are separate: every plan gets expiration; only Solo and Team get automatic reminder emails.
- You can still manually resend or follow up on an invoice regardless of plan.
