The verdict: can you vibe code Factorial?
Building a functional personal clone of Factorial is a serious undertaking; keeping pace with multi-jurisdiction compliance and expansive modules requires months of dedicated engineering.
Factorial is a massive enterprise platform comprising HR, payroll, IT device management, expenses, and AI agents. While you can build a clean single-tenant web dashboard containing an employee directory, time-off tracker, and simple document store in a few weeks using modern AI tools, you will inevitably hit walls around complex role-based permissions, multi-step approval state machines, and legal e-signature audit trails. The software's real value lies in its regulatory compliance engine and extensive integrations—areas where an AI coding agent will scaffold the CRUD wrappers but leave you to manually implement brittle business logic.

Build guide
01Project Scaffolding & Database Schema
Initialize the Next.js project with Tailwind CSS and define the comprehensive relational schema for employees, departments, time-off policies, time logs, and documents in Supabase.
Create a new Next.js 16 app with TypeScript and Tailwind CSS. Configure Supabase client bindings and write SQL migration files for a multi-tenant HR platform. Define tables for 'organizations', 'users', 'departments', 'time_off_requests', 'time_logs', 'documents', and 'expenses'. Include foreign key relationships, cascading deletes where appropriate, and indexes for lookup performance on organization_id and user_id.02Authentication & Organizational RBAC
Implement authentication using better-auth coupled with role-based access control (Admin, Manager, Employee) and organization scoping.
Set up better-auth in the Next.js application supporting email/password login and organization creation. Implement middleware and database schemas for Role-Based Access Control (RBAC) with roles: 'admin', 'manager', and 'employee'. Ensure that API routes enforce permissions so employees can only view their own records, managers can approve team requests, and admins have full system control.03Employee Directory & Org Chart
Build the employee directory interface, profile management views, and a hierarchical organization chart visualization.
Build an employee directory page featuring searchable data tables, filtering by department, and a detailed profile view for each employee showing personal info, contracts, and assigned manager. Also create an interactive organizational chart component using React Flow or Tailwind tree layouts that dynamically visualizes reporting lines based on the supervisor_id field in the users table.04Time Tracking & Absence Management
Develop the time-off request workflow, calendar view, and daily clock-in/clock-out tracking module.
Implement a time and absence management module. Create a calendar view using FullCalendar or custom React grids displaying team time-off. Build a request submission form for vacation/sick leave with multi-step approval routing. Add a daily clock-in and clock-out widget that records timestamps, break durations, and computes weekly total hours worked for payroll reporting.05Document Manager & E-Signatures
Create a secure document repository with file storage in Supabase buckets and a signature logging interface.
Build a document management section allowing administrators to upload company policies and contracts into Supabase storage buckets, attaching metadata to specific employees or entire departments. Implement a digital signature workflow where users can review a document and click 'Sign', recording a tamper-evident audit log entry with timestamp, user ID, and IP address.06AI Assistant 'One' Integration
Integrate an LLM-powered natural language chat interface that queries organizational tables to answer operational questions.
Build an AI chat interface named 'One' integrated with the Anthropic API. Implement tool-calling functions that allow the model to query internal database tables (e.g., fetching team headcount, summarizing pending time-off requests, or generating absenteeism reports based on company data). Ensure tenant isolation so queries are strictly scoped to the user's organization.
