Automatically chase unpaid invoices via WhatsApp and email without the awkwardness

Problem: Small businesses and freelancers often struggle with late-paying clients. Manually sending reminder emails is both awkward and inefficient, and many owners complain about clients not paying on time without wanting to damage relationships.
Solution: Connect Stripe or manually enter invoices, then automatically send personalized reminders before and after due dates via WhatsApp and email. Set escalating tones and track all reminders in one dashboard.
Users: Freelancers and small service businesses (design, consulting, contracting, etc.)
MVP: Manually add invoices and client contacts; auto-send email templates 3 days before and 1, 3, 7 days after due date; support WhatsApp Business API; dashboard showing reminder status; simple recovery analytics.
Revenue: Monthly subscription $9–$29 with tiered pricing by client count; or percentage fee on successfully recovered payments.
Why now: WhatsApp Business API and email automation tools are mature, allowing indie developers to integrate quickly; remote work increases need for lightweight tools.
