Reviewers say Puzzle makes startup accounting far easier to understand and manage, especially for founders without deep finance experience. They repeatedly praise its intuitive interface, real-time visibility into cash, burn, runway, and reports, plus integrations and automation that reduce spreadsheet work and month-end admin. Several users say it compares favorably with QuickBooks or Pilot and highlight helpful onboarding and support. Weaknesses are barely discussed; the only real caution is that some users are still early in setup or unsure how useful newer AI features will be.
