FAQ

Common Questions

How long until my application is ready?

It depends on scope. A catalog or simple app can go live in weeks; a full ERP is delivered module by module so you can start using it early.

Yes. Every portfolio piece above was built around a real business need — showrooms, property, retail, trucking and factories.

Is there a usage guide for our staff?

Yes. Every app includes an in-app User Manual so your team gets up to speed quickly.

Can it be used on a phone?

Yes. Every application is cloud-based with no installation — just open it in a browser, and it works comfortably on mobile. Some are also available as Android apps.

How secure is our data?

Role-based login, isolated data per company, locking of critical transactions, plus backup & rollback procedures.

Is there support after launch?

Yes. We support training, fixes and further feature development.
