# How to Vibe Code Your Own Bonsai (and Stop Paying for It)

> All-in-one business management and operations platform for freelancers and agencies

- Site: https://hellobonsai.com
- Category: Business Management & Operations SaaS
- Platforms: Web app
- Verdict: **Serious undertaking** (45/100 vibecodeable)
- Estimated effort: 4-6 weeks of intensive solo development

## Verdict

Build a personal subset covering timesheets, client invoices, and Kanban boards, or keep paying if you rely on production accounting syncs.

Replicating Bonsai means building six distinct SaaS apps under one roof: a CRM, an e-signing contract maker, a Gantt project manager, a time tracker, an invoicing generator, and an accounting ledger. While AI coding tools will scaffold individual models and UI views rapidly, handling edge cases in billable time calculation, recurring retainer billing logic, and document rendering pipelines will require extensive debugging over multiple weeks.

### What you can't replicate

- The massive library of jurisdiction-vetted legal contract and proposal templates
- Deep native accounting integrations with QuickBooks and Xero
- Zoom enterprise backing, compliance guarantees, and ongoing platform maintenance

## What it does

Consolidate your CRM, client proposals, contracts, project task boards, time tracking, expense tracking, and invoicing into one integrated workflow.

### Core features

- CRM & Deals Pipeline
- Estimates, Proposals & Legally Vetted Contracts
- Interactive Client Portal & Forms
- Project Kanban & Gantt Task Management
- Billable and Non-Billable Time Tracking with Timesheets
- Invoicing & Recurring Retainer Billing
- Expense Tracking & Basic Bookkeeping Ledger
- Productivity & Profitability Reporting

## The business

### Pricing

- Basic: $15/mo — Solo freelancers needing basic time tracking, task management, and CRM.
- Essentials: $25/mo — Active freelancers adding invoicing, client portals, and contracts.
- Premium: $39/mo — Most Popular: Established freelancers needing Gantt charts and workload management.
- Elite: $59/mo — Small agencies requiring custom roles, timesheet locking, and accounting sync.

### Funding

unknown raised.
Investors: Zoom Video Communications (Acquirer)

Founded 2016.
Team size: 20-50+ employees.

## The hard parts

- Generating legally binding document workflows with dynamic signature overlays
- Synchronizing concurrent timer states with billable hours aggregation across multiple users
- Building robust double-entry financial ledgers for invoicing, retainers, and tax compliance
- Designing complex multi-view project boards supporting both Kanban boards and interactive Gantt charts

## How to vibe code Bonsai

### Prerequisites

- Node.js (free): Required runtime for executing the Next.js framework and build toolchain.
- GitHub (free): Version control repository hosting and continuous deployment pipeline connection.

### Recommended AI tools

- Claude Code: Best-in-class agentic coding tool for scaffolding full-stack database models, API routes, and complex dashboard UIs across multi-file structures.
- Cursor: AI-native code editor ideal for reviewing diffs and making rapid iterative tweaks to complex form builders and kanban views.

### Stack

- Frontend: Next.js (App Router) with Tailwind CSS and shadcn/ui components
- Backend: Next.js Server Actions and API Routes
- Database: Neon (Serverless Postgres)
- Auth: better-auth
- Payments: Stripe (skipped for personal-use scope)
- Other: Resend for transactional client notifications, PostHog for product analytics

### Hosting

- Vercel (Zero-config deployment for the Next.js full-stack frontend and serverless API endpoints.): $0-20/mo
- Neon (Serverless Postgres database storing clients, projects, time entries, and invoices.): $0/mo

### Build guide

1. **Project Scaffolding & Database Schema** — Initialize the Next.js project with Tailwind CSS, configure better-auth with Postgres via Neon, and establish core database models for users, clients, projects, tasks, time entries, and invoices.

```
Scaffold a new Next.js 16 app with TypeScript, Tailwind CSS, and App Router. Set up better-auth connected to a Neon Postgres database using Drizzle ORM. Define database schemas for users, clients (name, email, company, address), projects (title, client_id, budget, status), tasks (title, status, due_date, project_id), time_entries (user_id, project_id, duration, billable, date), and invoices (invoice_number, client_id, total_amount, status, due_date). Create initial migration scripts and verify database connection.
```

2. **CRM & Client Management Dashboard** — Build the client management front office, enabling users to create, view, update, and delete client profiles along with a deal pipeline view.

```
Create a dashboard layout with a sidebar navigation for 'Clients', 'Projects', 'Time', 'Invoices', and 'Settings'. Build the Clients page with a data table listing all clients, a modal form to add/edit client details, and a detail view showing associated projects and invoices. Implement Server Actions to handle CRUD operations on the clients table with Zod validation. Use shadcn/ui table, dialog, and form components.
```

3. **Project Management & Task Board** — Implement project creation, kanban task boards, and task status updates linked to specific clients.

```
Build a Project Management view in Next.js. Create a projects list page and a dynamic project detail page (`/projects/[id]`). Inside the project detail view, implement a Kanban board with columns: 'To Do', 'In Progress', 'In Review', and 'Completed'. Allow users to create tasks, drag or move tasks between columns, assign them to phases, and set estimated hours. Store task states in the database via Server Actions and render real-time UI updates.
```

4. **Billable Time Tracking & Timesheets** — Develop a live timer widget and manual time-entry ledger distinguishing between billable and non-billable hours.

```
Build a Time Tracking module featuring an active timer widget in the app header (start, pause, stop) linked to selectable projects and tasks. Create a Timesheets page showing a weekly grid of logged hours, flagging entries as billable or non-billable. Implement backend logic to calculate total billable amounts per project based on hourly rate cards, storing entries in the time_entries table.
```

5. **Invoicing & Financial Ledger** — Create an invoice generator that aggregates unbilled time entries and expenses into clean, itemized invoices.

```
Build an Invoicing module at `/invoices`. Allow users to create a new invoice by selecting a client, pulling in unbilled time entries and custom line items automatically. Calculate subtotal, taxes, and total amounts. Render a clean printable invoice layout with a PDF download option using client-side printing styles. Add status management ('Draft', 'Sent', 'Paid', 'Overdue') and Server Actions to update payment status.
```

6. **Contracts, Proposals & Polish** — Add basic document generation templates for client proposals and contracts with signature placeholders.

```
Implement a Documents module supporting Proposals and Contracts templates. Create a dynamic template editor where users can select standard contract templates (e.g., Freelance Service Agreement), populate client variables, and generate a shareable public link for client review and digital signature confirmation. Polish the application UI, add error boundaries, loading skeletons, and ensure responsive mobile formatting.
```
