Open means control

Own the code, the data
and the way your ERP evolves.

No stripped-down community edition and no critical modules behind a paywall. The public repository contains the complete product.

Inspect and change anything

Study the real implementation, audit business rules, build integrations, or change the product itself. You are never limited to what an API happens to expose.

Keep data where you choose

Self-host on Linux, Windows or Docker. Your operational history stays in a standard PostgreSQL database under your own access and backup policies.

Leave vendor lock-in behind

No per-user contract controls your roadmap. The software, your extensions and your data remain usable even if you never buy a service from us.

Customization without a permanent fork

Extend the ERP.
Keep the core clean.

MyCompany is built on the open-source lsFusion platform. Add a small module that requires MyCompany, then extend or override the data model, forms and business logic. Product updates stay separate from your company-specific work.

  • ✓ Declarative business logic in plain .lsf files
  • ✓ IDE based on IntelliJ IDEA
  • ✓ No source rebuild for normal extensions

Supplier orders, receipts, invoices and automatic replenishment.

MFG

Manufacturing

BOMs, production orders, work centers, material use and actual cost.

POS

CRM

CRM & projects

Leads, activities, project tasks, time entries and customer work.

HR

∞
One shared data model. Sales, stock, production, finance and CRM update the same system instead of exchanging fragile spreadsheets.

One system, not a patchwork

Every workflow can cross module boundaries.

A sales order can reserve stock, create production demand, trigger purchasing and post revenue without duplicate entry. Because the platform owns the whole data model, your custom logic can do the same.

  • ACID transactions keep multi-step operations consistent
  • Role-based access applies across the application
  • Reports work directly with live operational data

Questions, answered

Before you deploy

Need to discuss an unusual workflow? Talk to our team.

Is the complete ERP really open source?

Yes. MyCompany is published in a public GitHub repository under the Apache 2.0 license. There is no reduced community edition; the same modules shown here are in the repository.

Can I use it commercially without a license fee?

Yes. Apache 2.0 permits commercial use, modification and redistribution. You may pay for infrastructure, implementation or support, but the software license itself is free.

Do customizations require a permanent source-code fork?

No. Normal customizations live in a separate lsFusion module that requires MyCompany and extends its model, forms and logic. That keeps product updates separate from your own work.

Where is business data stored?

In PostgreSQL on the infrastructure you choose. You control database access, backups, retention and the application server itself.

Which business modules are included?

Master Data, Accounting, Inventory, Invoicing, Purchase, Manufacturing, Sales, Retail/POS, CRM, Projects, HR, Fleet and Administration are included.

Can your team help with implementation?

Yes. Paid implementation, customization and support are available if you need them, while the source code and self-hosted product remain free to use independently.
