The basics

What is custom ERP software?

ERP (enterprise resource planning) software connects a company's core operations, such as inventory, purchase, sales, production, finance and HR, in one system with one database. A custom ERP is built for one company's processes, so teams stop re-entering data and managers see live numbers.

Ready-made ERPs are powerful but often force you into their way of working, charge per user and need expensive consultants to customise. A custom ERP costs more up front but fits exactly and has no licence fees.

FAQs

ERP software development: common questions

How much does custom ERP software cost in India?

The final price depends on modules, users and integrations. We give a fixed quote after a free consultation.

Custom ERP or ready-made (SAP, Odoo, Zoho)?

Ready-made ERPs suit standard processes and fast starts. A custom ERP suits businesses with unique workflows, many integrations or high per-user licence costs. We'll tell you honestly which fits in the free call.

Can we use the ERP on mobile?

Yes. Our ERPs are web-based and work on phones and tablets; we can also build a mobile app for field or warehouse teams.
