Dynamics 365 developers who speak .NET
Plugins, integrations and clean-up of Dynamics 365 CRM, by engineers who know both the platform and the C# code behind it. For Privalgo we cut 159 unmanaged solution components down to 7 managed ones, and we’re still with them 2.5 years later.
Case study · Privalgo · United Kingdom
From a CRM nobody wanted to touch to one the team can trust
Privalgo’s Dynamics 365 had grown complex and fragile. A team of 3 audited it, cleaned up the solutions, fixed plugins and integrations, and recovered production when it broke.

When Dynamics 365 slows your team down
Most Dynamics 365 environments we see grew for years without a clear structure. That is fixable, step by step, without stopping the business.
- Every deployment to production feels risky.
- UAT and production no longer match, so tests do not tell you much.
- Plugins run on outdated .NET versions and nobody wants to touch them.
- Duplicate records and broken automations erode trust in the data.
- Your internal team spends more time firefighting than improving the CRM.

Yes. We regularly take over environments with years of unmanaged customisations and bring them into a clean, managed solution structure.

How do you charge?
Team Extension is billed monthly on Time & Material. Clearly scoped work, such as a clean-up or an upgrade, can be done for a fixed fee.
How do you use AI?
Our engineers work with Claude and Cursor in practically every project. It roughly doubles their output and shortens delivery by up to 40%, with the same savings on cost. Senior engineers stay in charge of architecture and review every AI-assisted change, and we agree with you up front which tools and models may be used on your code and data.
How much does it cost to work with you?
It depends on the seniority and the number of people you need. Team Extension and dedicated teams are billed monthly on Time & Material, with no recruitment fees, and most clients start with one or two engineers. Proofs of concept and clearly scoped projects can be done for a fixed fee. After a 30-minute call you get a concrete proposal with rates for the profiles you need.
