Our process
How we build an estimate.
01
Technical scoping
One to two weeks billed at our day rate to identify the risks, validate the target architecture and document the decisions.
02
Detailed quote
The quote sets out an itemised estimate, delivery plan and architecture. The engagement begins when it is signed.
03
Build
Code reviews, automated testing, continuous integration, production monitoring and regular demos are matched to the agreed scope.
Daily rate
A public day rate:
€750 excluding VAT.
This rate is the basis for scoping and time-based engagements. The quote sets out the scope, estimated days and any infrastructure or licence costs.
Ongoing maintenance
Our recurring agreements organise the updates, monitoring and changes needed to limit compatibility issues, vulnerabilities and incidents.
