Reviews and customer experiences

How do customers experience our services?

Rijnland District Water Authority

"In July 2017, the Audit Committee of the Rijnland District Water Authority asked DongIT to conduct a study within two months into the policy and practice of information security at the Water Authority. In the selection of research agencies, DongIT stood out because they asked striking questions and adapted their approach to previous actions that Rijnland had taken in the field of information security. The assignment was carried out according to plan and with integrity. The result exceeded our expectations. The report was clear and presented transparently to the Audit Committee."

DongIT has taken over technical management and maintenance for some of our platforms after the collaboration ended with the party that had built those platforms for us.

With little documentation and much research, DongIT supported us very well so that these business-critical platforms continued to run, and even strongly improved on several components.

DongIT is a professional but accessible club. For us it has been crucial that they are developers with whom you can have a good conversation, who think along and provide excellent advice during the entire design and development process.

Since 2011, DongIT is the party that, in addition to building well-functioning websites, also realizes the links with our CRM systems and email applications. For several projects, including the migration to a new CRM system, we cooperated pleasantly and were very satisfied with the result. The most important plus points for us are the level of knowledge, flexibility ("Everything is possible"), short lines of communication and active thinking.

Due to the rapid growth and development of the market, rapid, expert and scalable development of our environment is very important.

DongIT knows how to respond well to our wishes in a professional and flexible way, and has developed great solutions to some custom requests, such as:

  • Multiple countries and languages possibilities in the webshop.
  • Responsive technology development for all devices.
  • Custom linkage with warehouse management system.
  • Custom linkage with shipping software.
  • Custom linkage with marketplaces.
  • Various promotional functionalities.
  • Various legislation-related techniques (including GDPR, cookie legislation).

We are 100% dependent on our IT environment. We must be able to rely on a reliable and safe environment. In addition, we want to be able to focus on our core activities and we want to be relieved in terms of IT.

DongIT succeeds very well in delivering excellent services to small and medium-sized companies with an involved attitude.
