Estimate custom software development cost from business requirements.
Turn a rough CRM, ERP, booking, operations or SaaS idea into an indicative complexity, timeline and investment range before a detailed discovery process.
Move from a number to a reviewable project scope.
Start with the smallest useful version
Separate launch-critical workflows from ideas that can wait for a later phase.
List data and integrations
Document products, users, roles, APIs, payments, migration and reporting needs.
Confirm ownership and support
Clarify source code, credentials, deployment, training, maintenance and response expectations.
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.
Read the detailed guide before finalising a budget.
Understand cost drivers, scope decisions, hidden dependencies, delivery phases and questions to ask a development provider.
