Overdue Stripe Invoice Reminders for Service Shops

Chases overdue Stripe invoices for owner-run shops, then lists who to call.

Some owners lose 2 to 4 hours a week tracking who owes them. This tool chases late Stripe invoices in their voice and lists who to call.

In their words

our team spends an extra 8-10 hours every week by following up and tracking clients invoices just for the money we earn by doing their work

I forgot to chase a $400 invoice for 6 weeks — anyone else just completely lose track of this stuff?

r/smallbusiness on Reddit

The frustration isn't the money being late — it's the mental load of tracking who owes what and when you last followed up.

The pain point it solves: Manual Invoice Reminders

Small businesses and freelancers waste time and risk client relationships manually chasing overdue invoices.

Why those fall short

  • notices get lost, no error, no phone or app warning
  • auto-ACH only works if clients agree; no enforcement of late payment
  • clients go silent, ignore reminders, no visibility on payment date
  • clients still don't pay even after reminders
  • Sending step not automated; owner procrastinates on final click
