Most developers build POS, Inventory, and Payroll as separate apps. I build them connected.
Every transaction — whether from the POS, Inventory, or Payroll module — automatically posts a journal entry to the accounting books. No manual encoding. No separate systems. One engine.
To build a real ERP, you need more than coding skills. You need to understand Assets, Liabilities, Equity, and exactly where every debit and credit belongs. That's what separates an ERP developer from a CRUD app developer.
I built Quenta ERP from scratch — a multi-tenant SaaS ERP for Philippine SMEs, live with real clients across bakery, grocery, restaurant, and security agency businesses. Built solo. No team. No shortcuts.
