Custom Software Development

Turn one business or personal workflow into a clear plan or a focused web tool. Software Blueprint provides requirements and a clickable sample-data prototype, not a working app. Focused Web Tool builds one responsive workflow with one user role and private records. Both are available worldwide, using one agreed language and your supplied inputs. Shared portals, admin features, payments, integrations, and larger systems are quoted separately.

Package scope and handover

A useful boundary around one workflow.

Planning and building are separate
Software Blueprint delivers documents and a sample-data prototype. It includes no functional app, production data connection, or deployment. A later implementation needs its own agreed quote.
Personal records in the web tool
Focused Web Tool covers one role and independent records owned by each user. Shared records, admin dashboards, invitations, complex relationships, payments, integrations, and imports are outside the package.
Your inputs and accounts
We confirm fit, scope, one language, and required access before work. You supply final content, branding, approved policies, and suitable provider accounts. Accounts and licenses stay in your name.
Two payment milestones
50% at kickoff. The remaining 50% is due after you approve the preview, before any agreed activation and handover.
A schedule we agree together
Estimates begin after we receive the deposit, complete inputs, and access. Timing depends on compatibility, provider approvals where needed, and timely, consolidated feedback.
Handover and agreed-scope fixes
The agreed deliverables and any included walkthrough follow final payment. For 14 days after handover, corrections for failures against the agreed scope are included. New requirements and ongoing maintenance are quoted separately.
Agreed acceptance checks
We agree acceptance checks before work and review the deliverables against them before handover. Prototypes and review reports are checked against their agreed questions and scope.
