Expert developers,
Always available.

As soon as your software is live, we jointly assess the future plans. Do these consist of the necessary security updates or will there also be new features? A fixed amount of "SLA hours" provides certainty in availability and budget.

Always development hours

Guaranteed development capacity.

We often develop software based on our Service Level Agreement (SLA). With this we reserve a fixed development capacity, to ensure that future development can be done. The level of the SLA is determined by the expected work and associated "release roadmap" (with all future updates). This way we are always "agile" and we can deal with different types of challenges, such as:

  • Urgent problems and critical bugs.

  • Updates necessary for software security.

  • Innovative features or small optimizations.

  • Testing and launching of releases.



Solid processes save time and money.

The content and priorities of the roadmap are coordinated in consultation. This lays the foundation for estimating what weekly SLA development capacity is required. This capacity ensures that we can plan all future releases (usually 1 to 6 per year).

Because we actively work together, we can also be flexible in terms of prioritization in the roadmap. There is weekly contact regarding progress and objectives. We are 100% transparent in the hour usage so that we can transfer any unused SLA hours to the next month.

In this way we work on an optimal functioning of your software and we offer certainty in terms of capacity and budget.
