Payminder: payment reminders for small businesses

Small service businesses chase unpaid invoices manually, whenever someone remembers. They worry about damaging customer relationships, so they write too late or too softly.

The app sends polite reminders by email and SMS on a set schedule, and the business owner can see in advance what will go to each customer and when. Free tools on the product site include an interest calculator and a payment demand generator using current NBP rates.
