Firstbase?
BUILD FIRST
- A non-sensitive or read-only version of the core experience
- A manual review step wherever correctness or trust matters
- A narrow companion tool that removes a real piece of work
LEAVE FOR LATER
- Regulated decisions, payments, or irreversible actions
- Claims of correctness, compliance, or uptime that the MVP cannot support
- Sensitive integrations until security, support, and auditability are ready
RESEARCH NOTES
What this tool actually does.
Firstbase (firstbase.io) is a startup back-office automation platform, not a traditional legal tool. It forms US LLCs/C-Corps (Delaware or Wyoming) via Firstbase Start ($399 one-time) and provides ongoing services through Firstbase One. One bundles Agent Autopilot (registered agent, franchise tax, annual report reminders/filings), Mailroom Premium (physical US address/virtual mailbox), full-service accrual bookkeeping producing tax-ready financials, and state/federal tax filing for corporate and personal returns. It targets both US-based and international founders, advertises 24/7 global support, and includes legal-service credits via partnerships such as DLA Piper. Core value is managed compliance: the platform tells users what filings are due and completes them, rather than merely generating documents.
RESEARCHED BUILD PROMPT
Give this to your coding agent.
Build 'IncorporationOS' — a web app that recreates the Firstbase workflow for founders forming and running a US small business. Core flow: (1) onboarding questionnaire capturing business name, owner details, entity type (LLC/C-Corp), and state (Delaware or Wyoming); (2) one-time payment for formation; (3) automated generation of formation documents with a manual-review fallback queue; (4) post-formation dashboard showing compliance deadlines, registered-agent status, and annual-report dates; optional modules for virtual mailbox, bookkeeping ledger import, and tax-filing checklists. User-facing requirements: multistep wizard, entity comparison page, pricing page, admin dashboard with task queues, per-entity compliance calendar, document viewer (PDF/HTML), email notifications for due filings, and a public status page for filing progress. Technical requirements: Next.js + Tailwind front end, Node/Python API, Postgres with per-tenant schemas, Stripe subscriptions/one-time payments, S3 or equivalent for document storage, BullMQ/Redis for async filing pipeline, and JWT + role-based access (founder, accountant, admin). Implementation approaches: use react-hook-form with Zod for the wizard, a singleton compliance-engine service that computes filing deadlines from state rules, and serverless functions for PDF generation via Puppeteer. Integrate with a real formation API or emulate with a staging sandbox behind an interface. Do not copy Firstbase branding, copy, or visual design; invent your own name, layout, and content. Explicitly out of scope: providing legal advice, live state-filing integrations, actual CPA review, multi-state registered-agent networks, and tax filing engines — build stubs/interfaces with mock data instead. Include a README covering setup (env vars, seeding demo data), architecture decisions, and known limitations (e.g., jurisdiction rules are hardcoded example data).
