Custom Software Development
Bespoke software built around your own idea or the way you work.
Your project or side venture running on spreadsheets only you understand
Platforms deployable in days, customisable to your process, and available as a subscription or a one-time licence with source code.
Browse softwareMost technology problems are not caused by a missing tool. They are caused by layers that were built separately and never designed to work together. Cyntra builds systems across all eight — so strategy, software, automation, infrastructure and support reinforce each other instead of fighting.
Hover the stack to separate the layers

Projects overrun because scope was never defined, not because engineering is slow. This is the sequence we follow, and the reason architecture always precedes build and security review always precedes deployment.
A senior engineer, 45 minutes, no cost. We establish whether technology is the right answer.
We map the process as it actually runs — including the variations nobody documented.
Architecture direction, build-versus-buy analysis and a phased plan with costed confidence ranges.
Design system and interactive prototype validated before engineering commits.
Fortnightly demonstrations of working software against a fixed architecture.
Automated coverage, cross-device verification and user acceptance support.
Authorisation, dependency and configuration review before anything reaches production.
Infrastructure as code, rehearsed cutover and a tested rollback path.
Recorded sessions, operator documentation, repository and account transfer.
Hypercare period, then an optional retainer with reserved engineering capacity.
Where we can define the work precisely upfront, we publish a fixed price. Packages above $5,000 include a written justification of what drives the cost — deliverable count, integrations, architecture, QA and support duration.

Not a values list. These are operating commitments you can hold us to, and several of them cost us revenue.
We start with the commercial problem and the arithmetic behind it, not a technology preference. Several engagements end with us recommending you buy software or keep what you have.
Typed codebases, real test coverage, documented architecture. Built so another team could take it over — because you own it outright on final payment.
Threat modelling during architecture, server-side authorisation on every data path, secrets in a managed vault, and audit logging on sensitive records.
Infrastructure as code from day one, with cost modelled before migration and governed afterwards. Typically 15–30% recoverable on mature estates.
Retrieval grounding, evaluation harnesses and human review gates. We measure accuracy against a baseline rather than asking you to trust a demo.
Our team emails you status, milestone and delivery updates throughout the project. Risks are raised when we see them, not after they land.
Scope, exclusions and payment schedule in writing. Our team emails you invoices and receipts.
Defined response targets, monthly reporting and reserved engineering capacity. No ongoing engagement is required to keep what we built.
A US entity with a real address, real contracts governed by Kentucky law, and documented security practices you can review before you buy.
Practical pieces on automation arithmetic, MVP scope discipline, security prioritisation and migration risk — written by the engineers who do the work.
Talk to a senior engineer, not a sales desk. We will tell you honestly whether technology is the right answer — and what it should cost if it is.
