Frequently asked questions about Startup financial planning

Real answers from real users, pulled straight from launch discussions, forums, and reviews.

  • Puzzle can auto-draft tax‑ready financial statements and connects you to partner tax/accounting firms—helpful when preparing R&D credit documentation, though it doesn’t claim end‑to‑end R&D credit filing.

    • R&D tax credits: none of the listed replies explicitly advertise fully automated R&D credit filings. Puzzle prepares the financials and can help you find a tax specialist to file credits.
    • Payroll tax filings: users point to established payroll providers—Gusto, TriNet, ADP, BambooHR—for payroll + tax handling.
    • Central offers HR/payroll automation (government mail monitoring and taking action), which may cover filings depending on your situation.

    Ask each provider whether they automate R&D credit workflows and federal/state payroll tax filings for your jurisdiction.

  • Puzzle and Gilion focus on accounting, growth metrics, and fundraising prep — they don’t explicitly advertise cap table editing or equity management.

    • Puzzle: offers a Stripe-like general ledger API, one‑click accounting setup with Brex, and automatically drafts tax- and fundraise‑ready financials. No mention of native cap table tools.
    • Gilion: tracks growth metrics, builds investor-ready Decks and offers growth financing; it surfaces investor metrics but doesn’t state cap table management.

    If you need cap table workflows, check each product’s docs or integrations, or ask their support/partners for dedicated equity tools.
