Invoice Reminder Service for Tradespeople

Plumbers, electricians, and other tradespeople lose money when invoices go unpaid or unpaid longer than necessary. A simple automated service sends invoice reminders on a schedule (daily, weekly, etc.) and tracks payment status. Target users are small trade businesses with 1-10 employees who don't use accounting software.

Late payments are a chronic problem in the trades, and the post-COVID squeeze on small contractors — slower client payments, tighter margins — has made cash flow management more urgent than ever for one-person and small-crew operations. FreshBooks and QuickBooks both handle invoice reminders, but they require buy-in to a full accounting workflow that most tradespeople actively resist; the real competitor here is a whiteboard and a forgotten phone call. At $1k–5k/month, the math works if churn is low and acquisition is cheap — tradespeople talk to each other, so word-of-mouth in a single trade community or region can sustain early growth without paid spend. The biggest risk is that the problem is just easy enough to solve with a free tool (Wave, even Excel) that paying $20–30/month feels unnecessary, meaning conversion from trial to paid will be the number that makes or breaks it.
