# Ready-Made Modules Not Enough? We'll Build It Custom

Generated core + hand-written overrides — customize your logic while still getting core updates.

## How It Works

1

Tell us the specific logic, report, or integration you need

2

We build it in the overrides layer — the core stays untouched

3

The core keeps updating; your customizations are never overwritten
