2. Purchasing & SRM: Supplier relations, procurement workflows.
3. Production & Assembly: Bill of Materials (BOM), assembly/disassembly orders.

Built once for Essentials, reused by every vertical (Fleet, Logistic, ContainerHub, GrainElevator).

Кожен модуль проектується за наступним стандартом структури:

2. Transaction Data: Документи, що фіксують факти господарських операцій (Invoices, Orders, Payments).
