Manage Inventory + Invoicing + HR in One Free System

Running a business means juggling software. You track stock in one app, send invoices from another, manage employee leave in a third, and pay for every single one of them. By the time you add up QuickBooks ($35/mo), a separate inventory tool ($50/mo), an HR platform ($5/employee/mo), and a CRM ($20/user/mo), a 10-person company is burning $200+ every month — just to keep the lights on.

ERPNext is a 100% open-source ERP that replaces all of them in one system (GitHub | Official Website). It handles accounting, inventory, sales, purchasing, manufacturing, HR, payroll, CRM, and projects — and it runs on a single $10/month VPS that you fully own. No per-seat pricing. No feature paywalls. No vendor lock-in.

Over 30,000 companies use ERPNext, from small shops to manufacturers with hundreds of employees. The project has 37,500+ GitHub stars and is maintained by Frappe, a company that's been building open-source business software since 2008.

What You're Probably Paying Right Now

Most small businesses cobble together 4–6 paid tools. Here's the typical monthly burn:

ERPNext replaces all of these for $0 in software licensing. Your only cost is the server it runs on.

What You Need

• A VPS — 2 vCPU, 4GB RAM, 40GB SSD ($10–$15/mo from Hetzner, DigitalOcean, or Hostinger)
• Docker & Docker Compose v2 — installed on the server
• git — to clone the official deployment repo
• A domain name — optional but recommended (e.g., erp.yourcompany.com)
• 45 minutes — no coding skills required

Step-by-Step Setup

Step 1: SSH into your VPS

Log into your server as root or a sudo user. Make sure Docker and Docker Compose v2 are installed:

docker --version
# Docker version 27.x or higher
docker compose version
# Docker Compose version v2.x or higher

If Docker isn't installed yet, run:

curl -fsSL https://get.docker.com | sh

Step 2: Clone the Frappe Docker repo

ERPNext's official Docker deployment is maintained in a separate repository. Clone it:

git clone https://github.com/frappe/frappe_docker
cd frappe_docker

Step 3: Start the demo environment (fastest way)

For a quick test or small-team deployment, the single-file demo setup gets you running in minutes:

docker compose -f pwd.yml up -d

Wait 2–3 minutes for the ERPNext site to be created. You can check progress with:

docker compose -f pwd.yml logs -f create-site

Once the create-site container finishes, open your browser at:

http://YOUR_SERVER_IP:8080

Log in with the default credentials:

Username: Administrator
Password: admin

Important: Change the admin password immediately after first login (Settings → Users → Administrator → Set Password).

Step 4: Production setup (recommended for real use)

The demo setup is fine for testing, but for a real business deployment you'll want the production compose file with proper environment variables:

# Copy the example env file
cp example.env .env

# Edit .env and set these variables:
# SITES=yourcompany.com
# DB_PASSWORD=choose_a_strong_password
# ADMIN_PASSWORD=choose_a_strong_admin_password

# Generate a long, random secret for the site
docker compose --profile production up -d

This starts ERPNext with MariaDB, Redis cache, queue workers, and a scheduler — all the components needed for a stable production environment.

Step 5: Create your first site

If you used the production setup, you need to create a site manually:

docker compose exec backend bench new-site yourcompany.com --admin-password 'YourStrongPassword' --db-root-password 'YourDBPassword'

# Install the ERPNext app on the site
docker compose exec backend bench --site yourcompany.com install-app erpnext

Step 6: Set up HTTPS with a domain

Point your domain's A record to your VPS IP, then configure a reverse proxy (Nginx Proxy Manager, Caddy, or Traefik) to terminate SSL. ERPNext runs on port 8080 by default — your reverse proxy forwards 443 → 8080.

With Nginx Proxy Manager (free, includes Let's Encrypt auto-SSL):

# Proxy Host:
# Domain: erp.yourcompany.com
# Forward Hostname: backend
# Forward Port: 8080
# Block common exploits: ON
# Force SSL: ON
# Request a new SSL certificate: ON

Step 7: Complete the setup wizard

Open https://erp.yourcompany.com and walk through the setup wizard:

1. Company details — name, country, currency, fiscal year
2. Chart of accounts — ERPNext auto-generates a standard chart based on your country
3. Brand — upload your logo (appears on invoices and reports)
4. Domain — choose your industry (Manufacturing, Retail, Services, Distribution, Education, Healthcare, etc.)
5. Enable modules — turn on Accounting, Stock, Selling, Buying, HR, Projects, POS as needed

The wizard takes 5 minutes. After it completes, you have a fully functional ERP.

What This Gives You

• Inventory management — track stock levels across multiple warehouses, set reorder levels, auto-generate purchase orders when stock runs low, batch tracking with expiry dates
• Invoicing & accounting — create GST/VAT-compliant invoices, track receivables and payables, generate trial balance, P&L, and balance sheet with one click
• HR & payroll — manage employee records, leave applications, attendance, expense claims, and run payroll with tax deductions; the Frappe HRMS module handles salary structures and payslips
• CRM — track leads, opportunities, and customer interactions in the same system where invoicing happens
• Manufacturing — production plans, work orders, BOM (bill of materials), job cards, and material requirements planning (MRP)
• Point of Sale — a built-in POS interface for retail, with offline sync support
• Projects & timesheets — manage projects, assign tasks, track billable hours, and auto-generate invoices from timesheets
• Multi-company, multi-currency — run multiple companies from one installation with consolidated reporting
• Email integration — connect your email account so customer replies auto-attach to the right records
• REST API & webhooks — integrate with any other tool (your website, Zapier/n8n, custom apps)

Cost Comparison: ERPNext vs SaaS ERP

The math is brutal in ERPNext's favor. Even comparing to the cheapest commercial alternative (Odoo Enterprise at $24/user/mo), a 10-person team pays $240/mo vs $15/mo — and ERPNext gives you more modules for that price, not fewer.

Too Complex? We Can Set This Up for You

ERPNext is powerful, but the initial setup — Docker, environment variables, reverse proxy, SSL, site creation, and module configuration — isn't everyone's idea of a good Tuesday afternoon. If you'd rather focus on running your business instead of reading Docker logs, we handle the whole thing.

What we do:

• Deploy ERPNext on your VPS with HTTPS, backups, and email configured
• Set up your chart of accounts, warehouses, and initial inventory
• Configure HR, payroll, and invoice templates with your branding
• Train your team on day-to-day operations
• Ongoing updates, security patches, and support

Frequently Asked Questions

Is ERPNext really free? What's the catch?

ERPNext is licensed under GPL-3.0, which means the software is free to use, modify, and even resell. The only costs are your server (a $10/mo VPS is enough for most small businesses) and optional paid services like managed hosting on Frappe Cloud or hiring someone (like us) for setup and support.

How many users can ERPNext handle?

On a 4GB VPS, ERPNext comfortably handles 20–30 concurrent users. For larger teams, upgrade to 8GB RAM and add a separate database server. ERPNext is used by companies with 500+ employees — it scales well with proper infrastructure.

Does ERPNext support GST, VAT, and other tax systems?

Yes. ERPNext includes built-in tax templates for India (GST), EU (VAT), UAE, UK, US, and 100+ other countries. The setup wizard auto-configures the right tax structure based on your country selection. You can also create custom tax rules for multi-state or multi-country operations.

Can I migrate my data from QuickBooks or other systems?

Yes. ERPNext has CSV import tools for customers, suppliers, items, and opening balances. Frappe also offers a paid data migration service. If you're working with us for setup, we include data migration as part of the onboarding.

What's the difference between ERPNext and Odoo?

Both are open-source ERPs, but ERPNext is fully GPL-3.0 with no feature paywalls — every module (HR, manufacturing, POS) is free. Odoo Community Edition is free but omits many modules (HR, payroll, advanced manufacturing) that are only in Odoo Enterprise ($24/user/mo). ERPNext also has a simpler, more consistent UI across modules.

Can I access ERPNext from my phone?

Yes. ERPNext's web interface is responsive and works in mobile browsers. Frappe also offers a native mobile app (Frappe Mobile) for Android and iOS that syncs with your ERPNext instance — you can approve leaves, check stock, and create invoices from your phone.

How do backups work?

ERPNext has built-in backup commands (bench backup) that produce compressed files of your database and uploaded files. In a Docker setup, you can schedule cron jobs to run backups and push them to S3, Backblaze B2, or any object storage. We recommend daily automated backups with 30-day retention.

What happens if the ERPNext project shuts down?

Because ERPNext is GPL-3.0 open source, your copy of the software keeps running regardless. Your data is in your own database (MariaDB or PostgreSQL) in standard SQL format — you can export it anytime. There's no vendor lock-in. The community has 730+ contributors, so even if Frappe (the company) changes direction, the project continues.

Next Steps

If you want to try ERPNext yourself, the demo setup takes 15 minutes and costs nothing beyond a $5 DigitalOcean droplet. If you want it done right — production-grade, with HTTPS, backups, and your business configured — we can set it up for you.

Either way, you're replacing $200–$600/mo in SaaS subscriptions with a single system you fully own. That's the kind of math that makes a difference.
