ERPNext vs Heimdyn for Small Factories
The ERPNext question is never really about features. It is about who maintains it.
Status: Heimdyn is in pre-launch. Five modules — quotations, sales orders, manufacturing, purchase orders and inventory — are built and shown on seeded demonstration data. General ledger accounting, GST e-invoicing and statutory filing are not part of the product. Join the waitlist.
What ERPNext gets right
ERPNext, built on the Frappe framework, is the strongest open-source ERP for Indian manufacturing, and it is not close. It covers manufacturing, stock, buying, selling and accounting. It has genuine Indian localisation. You can self-host it for the cost of a server, read every line of the source, and change anything.
For a company with technical capacity, that combination is very hard to beat. No per-user pricing, no vendor between you and your data, and a large community.
The part that decides it
Self-hosting an ERP is owning an ERP. Somebody has to:
- run and secure the server, the database and the queue workers
- apply version upgrades and test that your customisations survived them
- restore from backup the day something goes wrong, under time pressure
- write the customisations in the first place, in Python and JavaScript
If your answer to “who does that?” is a named person with the time, ERPNext is excellent. If the answer is “the founder, on Sunday”, the licence being free is not the number that matters.
The hosted Frappe Cloud option removes much of the operational burden and adds a monthly cost — at which point the honest comparison is against other hosted tools, not against zero.
The comparison
| ERPNext | Heimdyn | |
|---|---|---|
| Licence | Open source, self-hostable | Hosted product |
| Scope | Manufacturing, stock, buying, selling, accounting, HR, CRM | Quotation → dispatch operations only |
| Accounting / GL | Included | Not offered — keep your existing accounting |
| GST support | Yes, via India localisation | Not offered |
| Who runs the infrastructure | You, or Frappe Cloud | Us |
| Customisation | Source-level, Python / JS | Deliberately limited |
| Skills needed in-house | Real technical capacity | None intended |
| Best fit | Teams with an owner for the system | Factories that want the order flow to stop leaking |
Where they actually differ in intent
ERPNext is trying to be your whole system of record — books included. Heimdyn is trying to be the operating layer only, and to be simple enough that a plant supervisor raises a manufacturing order without training.
That narrowness is the entire design constraint. Five modules on three masters — product, raw material, BOM. A quotation becomes a sales order; the sales order raises a manufacturing order; shortfalls become purchase orders; goods receipts clear a three-way match; stock moves as the documents move. Accounting stays wherever it already is.
If you want one system for everything, that narrowness is a limitation and ERPNext is the better answer. If your books are fine and your floor is the problem, the narrowness is the point.
A fair way to test it
Do not compare feature lists. Pick the two or three things that currently go wrong every month — the shortage discovered too late, the cost rebuilt in Excel, the invoice paid for material that arrived short — and ask each option to walk that exact path end to end.
Then ask the second question, which is the one that actually decides it: after this is live, who upgrades it?
