# What is ATUM?

## The Modular Backbone for Custom Enterprise Platforms

Built for customization, composability, and domain precision, ATUM replaces the rigid “one-size-fits-all” ERP model with an agile, modular system you can tailor to any operation.

Inventory microservice tracks part usage across jobs.

### How it works?

ATUM uses a two-layer architecture to separate reusable business logic from customized workflows:

- Ledger
- Inventory
- AtenRP
- Procurement
- CRM

Project-specific rules, fields, print templates, and process flows — all defined declaratively for each implementation. This lets you adapt without rewriting logic, and scale without bloated systems.

ATUM is not another ERP. It’s the engine to build your own — faster, smarter, and purpose-built.

### Two Layer Architecture

- **Workflow Layer**  
  Pre-Project customization logic  
  - Document Ledger  
  - Custom Business Rules  
  - Document Templates (Via AtenRP)
- **Procurement**
