Payment Reminder Engine

A daily engine that chases unpaid invoices with escalating, polite reminders — get paid faster without the awkward manual follow-ups.

The starting problem

Chasing payments is awkward and time-consuming, and late invoices quietly strangle a small business's cash flow.

1. 1.

   The workflow

   

   It reads the invoices, skips the paid ones, and chases the rest with an escalating tone.

2. 2.

   The reminder received

   

   A polite reminder with the invoice and amount, friendly, firm, or urgent depending on the delay, in the client's language.

3. 3.

   The invoices source

   

   Invoice tracking drives the tone automatically: you get paid faster without the awkward chasing.

How it works

What we built

1. 1

   A daily scheduler reads the invoices sheet and finds what's unpaid.

2. 2

   It reminds 3 days before the due date and again while overdue, with a tone that escalates politely as the delay grows.

3. 3

   Each reminder is timestamped so customers are never spammed, and the flow stops the moment an invoice is marked paid.

Highlights

• Get paid faster with zero awkward manual chasing.
• Escalating tone matched to how overdue the invoice is.
• Spam-safe: one reminder per invoice per day, max.
