Developer (X++ / .NET) Market Overview

Dynamics 365 developers turn functional designs into working software across Microsoft's business application stack. Work splits broadly into three technical streams: Finance & Operations (F&O), which is built primarily in X++; Customer Engagement (CE/CRM) and the Power Platform, which rely on C#/.NET plug-ins, the Dataverse Web API, JavaScript and low-code configuration; and Business Central, the SME ERP descended from Dynamics NAV, developed in AL. Many roles also touch Azure services, Power Automate, custom connectors and integration tooling.

UK demand is strong and steady, driven by ongoing migrations from legacy on-premises Dynamics AX and NAV to cloud Dynamics 365, plus a wide partner ecosystem of Microsoft implementation specialists. Permanent salaries vary by stream and seniority, with experienced developers commonly in the £50,000–£75,000 range and the median Dynamics 365 developer salary around £62,500. Contract demand is healthy, with CE/CRM developer day rates frequently quoted in the £450–£600 region depending on IR35 status and clearance requirements.

Specialisation matters. X++/F&O developers are comparatively scarce and tend to command a premium, while CE and Power Platform skills overlap with the broader low-code market and are in high volume demand. Business Central/AL developers are sought by Microsoft partners serving the SME market. Security-cleared (SC/DV) roles in government and defence typically pay above market.

The category spans Microsoft partners (consultancies and ISVs), in-house teams at end-user organisations, and independent contractors. Hybrid and fully remote working are both common, and a portion of work is delivered to global clients, so day-rate and salary benchmarks are often discussed alongside USD equivalents.

Frequently asked questions

What is the difference between an F&O developer and a CE developer?
F&O (Finance & Operations) developers work mainly in X++ on Microsoft's enterprise ERP, using the extension framework and Chain of Command. CE (Customer Engagement) developers work on the CRM apps and Power Platform, primarily writing C#/.NET plug-ins, JavaScript and Dataverse integrations. The two use different languages and tooling, so most developers specialise in one stream.
Which certification should a Dynamics 365 developer get first?
It depends on your stream. For Power Platform and CE, PL-400 (Power Platform Developer Associate) is the core developer certification; PL-200 is a useful functional complement. For F&O, MB-500 (Finance and Operations Apps Developer Associate) is the primary exam. Business Central developers focus on AL development rather than a single developer-specific exam.
Do I need to know X++ to work as a Dynamics 365 developer?
Only for Finance & Operations roles. X++ is specific to F&O (and legacy Dynamics AX). CE/Power Platform and Business Central roles use C#/.NET, JavaScript and AL instead. X++ skills are relatively scarce, which can make F&O developers well paid.
What salary can a Dynamics 365 developer expect in the UK?
Experienced developers commonly earn between £50,000 and £75,000, with the median Dynamics 365 developer salary around £62,500. Juniors typically start in the high £20,000s to £40,000, while technical leads can reach £85,000–£95,000+. Specialism, certifications and security clearance all affect pay.
What are typical contract day rates?
Day rates vary by stream and IR35 status, but Dynamics CE/CRM developer contracts are commonly advertised in the £450–£600 range, with the median CRM developer rate around £519/day. F&O and senior/lead contractors can command more, and security-cleared roles pay a premium.
Is Business Central (NAV) development a separate career path?
It overlaps but is distinct. Business Central is developed in AL using Visual Studio Code (with legacy C/AL for NAV upgrades), and is most in demand among Microsoft partners serving small and mid-sized businesses. Many developers stay within the BC/NAV ecosystem throughout their careers.
Can Dynamics 365 development be done remotely?
Yes. Hybrid and fully remote roles are both common, and a portion of work is delivered to global clients. Some UK public-sector and defence roles require on-site presence and security clearance, which limits remote options but often increases pay.
