System Overview — Vertex ERP Manual

1. What it is

Vertex ERP is a modular ERP-style platform for people, money, supply chain, operations, and collaboration. Users work inside permission-gated modules on a shared ABP/.NET + Angular stack.

2. Main highlights

Modular systems — HR, Recruitment, Attendance, Payroll, Evaluation, Finance, Cost Accounting, Sales, Purchasing, Inventory, Manufacturing, Garage, Assets, Communication, plus Identity/tenancy administration
Shared identity — Users, roles, and permissions; HR employees can auto-link to login accounts via PersonId
People lifecycle — Hire and master data in HR/Recruitment → time in Attendance → pay in Payroll → performance in Evaluation
Commercial chain — Purchasing and Sales connect to Inventory and Finance posting paths
Operations — Manufacturing and Cost Accounting for production/cost; Garage for fleet; Assets for fixed assets
Communication — Internal messaging and external email across the tenant
Host tooling — Tenants, monitoring hub, white-label branding, audit logs
