ERPNext shines when departments are connected in one end‑to‑end flow. Key modules:

  • Accounting: automated entries, payments, bank reconciliation, cost centers.
  • Sales & CRM: quotations, sales orders, pricing, pipeline tracking.
  • Purchasing: purchase requests, supplier quotes, approvals, vendor performance.
  • Inventory: multi‑warehouse, batches/serials, re‑order, stock counts.
  • Manufacturing: BOM, work orders, MRP, production tracking.
  • HR: attendance, leaves, payroll, expenses.

The biggest win comes from configuring document links and automated accounting, not running each department in isolation.
