How long does ERP development take?

ERP development typically takes 12-24 weeks depending on the complexity and number of modules. A basic ERP with 2-3 modules can be completed in 12-16 weeks, while enterprise solutions with multiple modules may take 24+ weeks.

Can you integrate with our existing systems?

Yes, we specialize in integrating custom ERP systems with existing software, third-party applications, cloud services, and legacy systems through APIs, webhooks, and custom connectors.

What modules can be included in a custom ERP?

Common ERP modules include Financial Management, Inventory Management, HR Management, Supply Chain Management, Manufacturing, CRM, and more. We can develop any module based on your business needs.

Is cloud-based or on-premise ERP better?
