When should I choose custom software over off-the-shelf?

When you keep working around your current tools, pay for features you do not use, or need systems that talk to each other in a way the market products do not support.

What systems can 3J Effect build?

CRM, ERP, WMS, EMS and LMS systems, plus custom portals, dashboards and integrations.

Why work with a local Sydney team?

You can meet us face to face in Norwest, explain your process in person and see changes quickly, without time-zone delays.

Can you integrate with our existing tools?

Usually yes. We review your current software and data during discovery and plan the integrations.

Who owns the finished system?

Ownership terms are agreed in writing before the project starts.
