Questions, answered

Will it send emails to customers without my approval?

No. Every reminder is saved as a Gmail draft and left unsent. You review and send each one manually. Nothing goes to a customer automatically.

What does the reminder email say?

A short, polite note with the invoice number, amount due, and a reminder that payment is overdue. Provide a tone example and WebRun will match your voice.

What about customers already on a payment plan?

It skips any invoice you have flagged as in dispute or on a payment arrangement, so those customers are never incorrectly chased.

Put this on autopilot.
