What are your go-to steps to collect an unpaid invoice when clients don't respond?

It’s frustrating when clients go quiet on unpaid invoices. I’ve sent multiple reminders over the last couple of months without any feedback.

Not sure if I should escalate my approach or if there’s another tactic I might consider to get through.

Stop any ongoing work if you can. Send a formal demand letter by certified mail. Give them 10 days to pay before taking legal action. Clients often respond to something official. If they’re really unable to pay, you’ll know where you stand instead of chasing them with reminders.

Show up at their place if you know where they work.

Try reaching out through a different contact method if you have one. Sometimes invoices get lost or forgotten in their system.

If that doesn’t work, mention late fees or interest charges in your next communication. Most clients wake up when they realize the bill is growing.

Phone calls work better than emails sometimes. People ignore emails but usually pick up the phone.
