When to Send an Invoice Reminder

The timeline that gets you paid

Send the invoice the day the work is done — not the end of the week, not 'when you get around to it'. Then: a gentle check-in at day 7, a firmer nudge at day 14, a direct call at day 21, and a final notice at day 30 if your terms allow it.

Each step gets slightly more formal. The customers who pay on time barely notice; the ones who needed a push get one before it becomes a problem.

What to write at each stage

Day 7: 'Just making sure you received invoice #104. Happy to answer any questions.' Day 14: 'Invoice #104 is now 14 days past due. A payment of $X brings your account current.' Day 21+: stop apologizing and state facts, terms, and next steps.

Short beats long. Every reminder should take the reader under ten seconds to understand.

Why SMS reminders work

Email reminders get lost in inboxes. An SMS invoice reminder — 'Invoice #104 of $540 is due Friday. Reply STOP to opt out' — is seen within minutes and has dramatically higher response rates. For overdue invoices, text is the fastest lever you have.

Just keep it service-like and compliant: clear sender, clear purpose, working opt-out.

Automate the boring parts

You should never have to remember to chase an invoice. Reminder software sends the day-7, day-14, and day-30 messages automatically, on schedule, and logs every touch. The system nags; you don't.

That's what turns a collection problem into a cash-flow process.
