Before You Decide
Questions to Settle Before Starting Web Apps
Single or multi-tenant?
We explain the cost and risk of each so you choose with eyes open.

What about data security?
Encryption, access control, backups and audit logs are in scope.
Can we start small?
Yes. A focused first release with a clear roadmap beats a big-bang launch.

Yes, as a PWA with local caching and background sync.
Do you provide hosting?
We deploy to your cloud account or manage hosting for you.
How much does Web Apps development cost?
Cost depends on scope, integrations, compliance needs and the number of users or pages. After a short discovery we give a fixed or phased quote with clear milestones, so you can compare it with other options.
How long does Web Apps development take?
A first release usually takes 10 to 16 weeks, then continues in sprints.
What support do you provide after Web Apps development goes live?
We offer support retainers covering fixes, updates, monitoring and enhancements, plus a handover with documentation and training so your team is never locked in.
