Chase late payments automatically, politely
Late payments kill cash flow. This tool reads your invoices from a Google Sheet, calculates days overdue, and sends a sequence of increasingly firm reminder emails. Day 3: a friendly nudge. Day 14: a firmer reminder with the original invoice attached. Day 30: a final notice. Each email is personalised with the client's name, invoice details, and amount due. You review escalation before it happens, and everything is logged so you know exactly who owes what.
Target audience: Freelancers, agencies, and small businesses with recurring invoicing
