Stop chasing invoices.

Automated SMS and email reminders that follow up until your customers pay. Works on its own or connects to QuickBooks.

14-day free trial · No credit card required · For US contractors and freelancers

Getting paid shouldn't be the hardest part.

You did the work. You sent the invoice. Now you're waiting, and deciding whether to follow up again feels awkward.

Most invoice tools send a couple of email reminders and stop there. Nudge keeps going. It texts your customers, escalates in tone automatically, and doesn't stop until the invoice is paid.

No QuickBooks? No problem. Nudge works on its own too. Add invoices manually and let it handle the chasing.

How it works

1 Connect QuickBooks or add invoices manually

→

2 Set your reminder schedule: how often, how many, and what tone

→

3 Nudge texts and emails your customers until they pay. Mark it paid and the reminders stop.

✓ SMS and email reminders, up to 9 per invoice

✓ Works standalone or syncs directly with QuickBooks

✓ Messages escalate in tone: friendly first, firmer later, final notice last. In your exact words.

✓ Per-customer scheduling: different rules for different clients, or exclude someone entirely

✓ Mark paid to stop all reminders instantly

Works with QuickBooks. Or without it.

If you're on QuickBooks, connect your account in one click. Your invoices and customers sync automatically and Nudge adds what QB is missing: SMS reminders, more follow-ups, and messages that get firmer over time.

Not on QuickBooks? Nudge works fine on its own. Add invoices manually and it handles the rest.

What Nudge adds:

✓ QB sends 3 email reminders. Nudge sends up to 9, via SMS and email.
✓ QB uses one schedule for everyone. Nudge lets you set different schedules per client.
✓ QB reminders stay flat in tone. Nudge starts friendly and gets firmer automatically.

Use QuickBooks for the books. Use Nudge to get paid.
