Buyer's guide
Solopreneurs run one-person businesses with software needs different from freelancers (project-based) and small businesses (employees). The core stack: payment + invoicing (Stripe + Bonsai or HoneyBook or Wave), accounting (QuickBooks Solopreneur, FreshBooks, Wave), email + CRM (lightweight: Streak, Folk, Notion CRM or ConvertKit/Beehiiv if newsletter-driven), automation (Zapier, Make, n8n), and an audience platform if relevant (Twitter/LinkedIn for B2B, Instagram/TikTok for B2C, podcast or newsletter).
The financial reality: solopreneur revenue typically caps at $100k-$500k without leverage (tools, contractors, products). The leverage is automation + productized offerings (replacing custom 1-on-1 work with packaged offerings). Tools that support productization (Gumroad, Lemon Squeezy for digital products; Calendly + Stripe for paid bookings; Circle/Mighty for community-as-product) move solopreneurs past the time-for-money ceiling.
