Factorial factorialhr.comCan AI replace Factorial?
A consolation build is possible, but the paid product's decisive value sits outside a solo rebuild. For Factorial, track documents, leave, schedules, and onboarding without payroll calculations. The hard boundary is hr workflows, time, payroll integrations, compliance, analytics, and support, plus compliance, payroll, and regulated integrations.
01What it costs
Checked Aug 10, 2026 · source: factorialhr.com.
| Plan | Monthly | Billed yearly | What you get |
|---|---|---|---|
| Factorial Core | $8 | — | Starts at $8/user/month; employee directory, onboarding/offboarding, payslips, bulk documents, e-signatures, notifications, and fillable PDFs |
| Custom module bundle | — | — | Quote-selected modules can include Time Off, Time Tracking, Performance, Shift Management, Recruitment, Engagement, Projects, Expenses, and Training |
Hidden costs: The $8/user/month figure is a starting price for Core, not a complete bundle. Operational modules are separately selected and quote-priced, so the final per-user cost is not public.
02Could AI build it for you?
The core job: Track documents, leave, schedules, and onboarding, maintain approvals and records, and export data without calculating payroll or making employment decisions.
What a working version needs:
- PostgreSQL
- private self-hosted deployment
- strict admin access
- documented retention policy
Editorial comparison targets the Business plan and a internal records tracker without payroll DIY substitute. Recheck price before merge.
03What you'd give up
- HR workflows, time, payroll integrations, compliance, analytics, and support
- payroll rails
- tax and labor-law compliance
- benefits integrations
- identity checks and global employment infrastructure
People still pay for Factorial because HR platforms survive because mistakes affect pay, benefits, immigration, and legal obligations, not because forms are difficult to render. The recurring cost buys sensitive data, access, retention, audit, payroll calculations, filings, benefits, employment law, incident response, and support, not just the visible interface.
04Free and cheaper alternatives
Documents, leave, schedules and onboarding for ten people; user eleven starts the subscription.
Versus paying: The free plan stops at ten total users and has less HR-record and approval depth than Factorial.
connecteam.com →Documents, onboarding, leave and rotating shifts in Docker; administration is the free-plan limit.
Versus paying: Its administration, integrations and polish lag Factorial, and deployment, security, backups and upgrades are yours.
horilla.com →Employee documents, onboarding, leave and shifts in one full HR stack; you operate the stack.
Versus paying: It replaces Factorial's managed simplicity with a large ERP-adjacent stack whose operations and upgrades are your responsibility.
frappe.io →05The build prompt
Paste this into an AI coding tool (such as Claude, ChatGPT, Lovable or Replit) to build your own version. Read the verdict first: this one is hard to get right.
Build a closest honest personal substitute for Factorial in an empty repository. Use Next.js 15, TypeScript, PostgreSQL, Drizzle ORM, and Docker Compose; do not offer alternative stacks. The core loop is: track documents, leave, schedules, and onboarding, maintain approvals and records, and export data without calculating payroll or making employment decisions. Make the first run work locally with one documented command. Store all user data locally by default and make export straightforward. Put secrets in .env, ship .env.example, and never commit credentials. Implement employees, teams, roles, documents, leave requests, equipment, onboarding tasks, and acknowledgements. Use least-privilege roles and log every read or change to sensitive records. Add approval workflows, expiry reminders, export, retention, deletion holds, and encrypted backups. Keep compensation fields optional and never calculate payroll, taxes, benefits, or statutory filings. Provide a data dictionary and explain which fields should not be stored without legal review. Ship Docker Compose, health checks, disaster recovery, and an emergency-access procedure. Include clear empty, loading, success, and recoverable error states. Add input validation, safe filenames, and graceful handling of unavailable APIs. Write focused tests for the core transformation and one end-to-end happy path. Create a README with setup, architecture, permissions, data location, and backup steps. Do not add accounts, billing, telemetry, analytics, or a hosted control plane. Do not claim to reproduce proprietary data, network liquidity, regulated access, or frontier infrastructure. Deliberately leave out payroll calculation or money movement. Deliberately leave out automated hiring decisions or applicant scoring. Deliberately leave out tax, benefits, immigration, identity, and global-employment compliance. Finish by running the tests and listing the exact commands used.
