Quality you can audit. Software you can trust.
We operate under an ISO 9001:2015 certified quality management system that governs how we gather requirements, how we build, how we validate and how we deliver.
Free, with a senior consultant. The plan is yours even if you don't hire us.
What ISO 9001:2015 is — and why it matters for software
ISO 9001:2015 is the international standard for quality management systems. It requires documented processes, defined owners, change control, measurement and continuous improvement, verified by an independent certification body.
In software development that becomes concrete: requirements are documented before code is written, every stage has acceptance criteria, and every delivery is validated with you before moving forward.
It is not a decorative badge. The certification doesn't live in a PDF — it lives in every stage of the project we sign.
What it means for your project
Traceability
Every decision, scope change and delivery is documented. When an audit comes, the file is already complete.
Warranty
If the delivered software doesn't meet the signed specifications, we fix it at no additional cost. It's in the contract, not a verbal promise.
Transparency
At project close you receive the code, database and technical documentation. No recurring licenses, no contractual lock-in.
Risk mitigation
You don't pay for the next phase until you've validated and approved the previous one. If a stage doesn't meet the spec, we fix it at no cost.
How ISO 9001 applies to every project
- Documented diagnosis Analysis of processes, roles, integrations and pain points. A signed requirements matrix before any development.
- Architecture and proposal Technical architecture document + detailed commercial proposal with stages, timelines and investment ranges. The proposal is free of charge.
- Phased development Iterative build with partial deliveries. Each phase is validated with you before the next one starts. Payment per approved stage.
- Structured QA + UAT Internal QA + UAT support with your team. A pre-production environment to validate before going live.
- Deployment + training Formal cutover plan + end-user training (3-5 sessions) + user and administrator manuals delivered.
- Warranty + continuity 6 to 12-month warranty period + optional maintenance plan so your system keeps evolving.
Written correction warranty
6 to 12 months of warranty depending on project scope. If something doesn't work as specified, we fix it at no additional cost. It's in the contract, not a verbal promise.
