What is an ERP system?
ERP (Enterprise Resource Planning) is software that combines all business processes of a company into a single platform. Accounting, inventory, sales, HR, customer relations — everything in one interface, one database.
Core ERP modules
- Finance & accounting — payments, cash, invoices, reports
- Inventory management — stock in/out, real-time tracking
- Sales & CRM — customers, orders, leads
- Purchasing & suppliers — POs, contracts, invoices
- Human Resources (HR) — timesheet, salary, leave
- Production (if applicable) — BOMs, planning, costing
- Reports & analytics — KPI dashboards, real-time data
Which businesses need ERP?

- Restaurants & cafes — menu, inventory, POS, delivery
- Retail — POS, real-time stock, pricing, loyalty
- Clinics — patient registration, scheduling, drug stock

- Logistics — warehouse, barcode, delivery routes
Benefits

How much does ERP cost?
Three main factors: number of modules, user count, integrations. Out-of-box SaaS solutions start cheaper but offer standard features. Custom ERP captures your specific business logic — 166 Tech specializes in this.
Custom ERP vs SaaS
SaaS = monthly subscription, fast deployment, limited customization. Custom = one-time investment, 2-6 months, full ownership and customization.
