  • r/Freelancers
  • r/Entrepreneurs
  • r/Invoice
  • r/smallbusinessowner
  • r/EntrepreneurRideAlong
  • r/SaaS

Tools they use today

  • QuickBooks
  • Google Sheets
  • Stripe
  • WhatsApp
  • Claude
  • Excel
  • Wave
  • Gmail

Why those fall short

  • process depends on one person remembering; collapses when they leave
  • repetitive manual entry, no connection between recurring billing and invoice issuance
  • sandbox does not guarantee document emission; auth credentials only for bulk creation
  • accountant promises reminders but sends them late
  • reminders take a lot of time, hard to bill, easy to forget
