Overview

What this engagement is

When off-the-shelf apps force you to work around them, the software becomes the constraint. Cyntra designs and builds custom software that encodes how you actually work — your approval rules, your pricing logic, the exceptions you currently handle in spreadsheets. We deliver in phases against a fixed architecture, so you get working software early and a system that stays maintainable after handover.

Problems this solves

  • Your project or side venture running on spreadsheets only you understand
  • Apps you pay for that cannot handle your pricing, approvals or exceptions
  • Re-entering the same information across three or four disconnected tools
  • No single place to see how your venture is actually doing
  • Every new customer adding more manual work for you

What is included

Discovery workshops and documented requirement analysis
Solution architecture and data model design
UI/UX design system and interactive prototype
Full-stack implementation with automated test coverage
Integration with your existing systems and third-party APIs

Security considerations

  • Threat model produced during architecture phase
  • Role-based access control with least-privilege defaults
  • Encryption in transit and at rest, secrets held in a managed vault
  • Dependency and static analysis scanning in CI
  • Full audit logging on sensitive records

Questions about this service

How do you price a custom build?
We run a paid discovery engagement first, then issue a fixed-scope proposal with milestone pricing. You own the discovery output whether or not you proceed with the build.
Who owns the code?
You do. On final milestone payment, all intellectual property, repositories and infrastructure accounts transfer to you.
Can we start smaller?
Yes. Most engagements begin with a Custom Software Discovery Package, which produces the architecture, scope and estimate before any build commitment.
