Describe the requirement.

Change the inputs to create a planning scenario. Use realistic values and verify the output before making a budget decision.

How to use the result

Move from a number to a reviewable project scope.

01

Start with the smallest useful version

Separate launch-critical workflows from ideas that can wait for a later phase.

02

List data and integrations

Document products, users, roles, APIs, payments, migration and reporting needs.

03

Confirm ownership and support

Clarify source code, credentials, deployment, training, maintenance and response expectations.

Common questions

Understand what the calculator can and cannot decide.

No. It creates an indicative planning range from selected inputs. A fixed proposal requires confirmed workflows, content, integrations, acceptance criteria and delivery responsibilities.

The calculation is designed to run in your browser. Kailvex does not intentionally receive the values unless you separately submit an enquiry.

Final cost can change with scope detail, design quality, data readiness, integrations, testing, security, hosting, store accounts, taxes and post-launch support.

Yes. Share the generated summary with Kailvex for a requirement review and a scope-based proposal.
