Trades Invoice Reminder SaaS

Small trades businesses — plumbers, electricians, HVAC techs — lose thousands each year to late invoices. The average tradesperson is chasing over £6,000 in overdue payments at any given time, and 82% of small business failures trace back to cash flow problems. Yet most tradespeople don't have the discipline or bandwidth to follow up consistently. Existing tools either bundle reminder features into expensive field-service platforms starting at $49/month, or offer generic invoicing with no automated chase logic. This SaaS fills that gap: it connects to QuickBooks or Xero, detects overdue invoices, and sends timed email and SMS reminders with payment links on a schedule the user configures once and forgets. At $19–$49/month based on invoice volume, it costs a fraction of full platform alternatives. A comparable micro-SaaS has proven $14K MRR is achievable. With 55% of B2B invoices paid late, the demand is real and persistent. The build is straightforward — a 4–6 week MVP using SendGrid, Twilio, and standard accounting API integrations — making this a low-risk, fast-revenue opportunity in a segment nobody is serving with a focused product.
