A founder in Mumbai got tired of paying SAP.

So in 2011 he wrote his own ERP.

15 years later, that ERP runs accounting, inventory, HR, payroll, manufacturing, CRM, and projects for thousands of companies.

It is called ERPNext.

It is free. GPL-3.0. 36,178 stars. Pushed today.

The math is the part that feels illegal.

SAP S/4HANA Public Cloud lists at $200 to $300 per Advanced user per month.
NetSuite starts at $999 a month plus $129 to $199 per user.
Microsoft Dynamics 365 Business Central is $80 to $110 per user per month.

A 50-user NetSuite deal lands around $77,400 a year in licenses plus $75k to $125k in implementation.

A 500-user SAP RISE contract sits between $800k and $1.2M a year.

ERPNext does the same modules. Accounting. Inventory. Payroll. Manufacturing. CRM. Projects. Sales. Purchase. Assets.

SAP implementations take 6 to 18 months.

ERPNext is one docker command. Minutes.

Rushabh Mehta started it because he could not afford SAP for his family business. He built it on Frappe, the MIT-licensed Python framework that powers it. 278 contributors. 11,873 forks. v16.25.0 shipped last week.

The whole stack is yours. Self-host it. Fork it. Strip the branding. Ship it to a client.

The ERP every Fortune 500 pays millions for is sitting in a public repo, written by a guy in Mumbai, and you can run it on a $5 VPS tonight.

As a SOFTWARE ENGINEER, are you scared of BACKEND DEVELOPMENT?

I promise you'll enjoy it after going through this thread:

[ result after 30 days: ]

operating costs dropped 87%, output quality dropped 4% on average, revenue unchanged

the most important that these models will be not banned in a month and i can run them locally

nobody will steal my data and i can learn them as i need

full article drops tomorrow with:
> exact routing logic per task type
> the 2 cases where I still pay for American
> the migration playbook anyone can copy in a weekend

VERY IMPORTANT to get migrated now, while it's not too late

Made a set of “Summer Sky Low-Angle Portraits” with ChatGPT-Image2.

Low angle, blue sky, full-body framing.
Hair flying, skirt moving, real skin tones.

It feels like the exact second when the wind gets stronger and the camera catches it.
