Payment Reminder Agent

Never chase a late payment again. This workflow automatically sends daily reminder emails to clients as their payment due date approaches.

Who Is This For?

  • Freelancers managing multiple clients
  • Small business owners tracking invoices
  • Finance teams automating payment follow-ups

How It Works

  1. Runs on a daily schedule — A scheduled trigger fires once per day at a set time.
  2. Reads client data from a spreadsheet — Pulls rows containing each client's name, email, and payment due date from Google Sheets.
  3. Calculates remaining days — A code node computes how many days remain until each client's due date.
  4. Filters to the 7-day window — Only clients with 1–7 days remaining are kept; everyone else is excluded.
  5. Sends reminder emails — A personalized payment reminder email is sent to each qualifying client via Gmail.

Spreadsheet Format

Your Google Sheet should follow this structure:

Column AColumn BColumn C
NameEmailDue Date
Jane Doejane@example.com2025-02-15
John Smithjohn@example.com2025-02-18
  • Name — The client's display name, used in the email greeting.
  • Email — The recipient address for the reminder.
  • Due Date — The payment due date in a standard date format (e.g., YYYY-MM-DD).
