Yes, you can implement an ERP in less than an hour on a Raspberry Pi — and it won't cost you anything

The persistent myth of overpriced ERPs

If you own a small business, you have probably heard this phrase a thousand times:

"An ERP is complicated, expensive, and reserved for large companies."

At ZEDM Solutions, we love to break myths.

So we asked ourselves:

💭 What if we could install a real ERP — the same one used in factories or restaurant chains — on a $100 mini-computer?

Spoiler:we can.

All you need is a Raspberry Pi 4, amicroSD card, and a good dose of curiosity.

(Bonus: a strong coffee helps too.)

Why this trial is not just for geeks

Many small businesses delay their digital transformation because:

• licenses cost a fortune,

• the infrastructure looks like it came out of a science fiction movie,

• and the timelines scare your accountant.

But with open source solutions like ERPNext or Odoo, and a little Linux hard work, you can:

• test a complete ERP for free,

• manage your sales, purchases, inventory, and finances,

• show your team that an ERP,is not a three-headed monster.

It’s literally like taking a Tesla for a test drive… but in your living room, with no monthly payments.

Required hardware 

In 1 hour flat: your ERP runs like a charm

1️⃣ Flash your SD card

DownloadRaspberry Pi Imager, selectRaspberry Pi OS Lite (64-bit) and enable SSH.

2️⃣ Connect and update

sudo apt update && sudo apt upgrade -y

3️⃣ Add a bit of swap (virtual memory)

sudo fallocate -l 2G /swapfile
sudo chmod 600 /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile

4️⃣ Install the prerequisites

sudo apt install -y git python3-pip python3-venv mariadb-server redis-server
curl -fsSL https://deb.nodesource.com/setup_18.x | sudo -E bash -
sudo apt install -y nodejs
sudo npm install -g yarn

5️⃣ Install Bench (the ERPNext manager)

mkdir ~/frappe-env && cd ~/frappe-env
python3 -m venv venv
source venv/bin/activate
pip install frappe-bench

6️⃣ Create your ERPNext site

mkdir ~/frappe-bench && cd ~/frappe-bench
bench init --frappe-branch version-15 frappe
cd frappe
bench new-site erp.local
bench get-app --branch version-15 erpnext
bench --site erp.local install-app erpnext
bench start

And there you go.

🎉 Congratulations! You just set up a free ERP in one hour.

In one hour, you get…

✅ A complete CRM

✅ Sales, purchases, and inventory management

✅ An accounting module

✅ HR, payroll, and even production

✅ A platform accessible from your laptop or phone

All of this on a small box the size of a deck of cards.

A few sarcastic truths

• The Pi's "Desktop" mode? Forget it. It's cute but slow.

• Without swap, your ERP will crash faster than a Windows server without a backup.

• Wi-Fi is good. Ethernet is better.

• An SD card lasts 6 months. An SSD lives happily.

• And no, it's not magic: if you break everything, you'll have to start over. But that's learning.
