Reminder Email for a Small Unpaid Invoice (Free Templates for Freelancers)

Small invoices are the ones clients forget. A $90 invoice does not trigger anyone's alarm bells, so it sits at the bottom of an inbox for months. You do not need a formal escalation sequence for these. You need a short, friendly email that makes paying take less effort than replying, sent on a predictable schedule.

Make paying effortless

• Keep the email under five lines. Small amount, small email.
• Put a one-click payment link (card or PayPal) at the top, not buried at the bottom.
• Re-attach the invoice so they do not have to search for it.
• Mention the amount in the subject line. "$85" gets opened and paid faster than "Invoice reminder".

Small-invoice habits that help

• Take card payments or require payment upfront for jobs under a set amount.
• Bundle small recurring charges into one monthly invoice.
• Send the first reminder the day after the due date. Small invoices go stale fast.
• Decide your cut-off in advance: after a final note, either pause future work or let it go, rather than chasing for months.
