FAQ

Frequently asked questions

Can you integrate an application with our existing tools?

Often, yes. We first confirm that the required systems expose suitable APIs, permissions and documentation before including an integration in the proposal.

Can the product support different user roles?

Yes. Authentication, permissions and role-specific experiences can be designed around the project's security and workflow requirements.

Can we begin with a smaller first version?

Yes. We can identify the smallest useful scope, while keeping later integrations and features visible in the technical plan.
