Microsoft Dynamics 365 Development in Derry
Plug-in and custom development on Dynamics 365 for Derry organisations. Code registers into an execution pipeline with defined stages, and anything running synchronously sits inside the user's transaction with a hard time limit — so where you register a plug-in matters as much as what it does.
Why this comes up
The problem
A plug-in calls an external service on save, the service is slow one morning, and users cannot save records at all.
What you get
What we deliver
- Plug-ins registered at the stage that matches what they need to do
- External calls kept out of synchronous steps, where a slow response blocks users
- Asynchronous processing used for work that need not complete before the save
- Infinite loops prevented, since a plug-in updating its own table re-triggers itself
- Errors handled so a failure produces a useful message rather than a stack trace
- Code kept minimal, with configuration and Power Platform used where they suffice

Microsoft Dynamics 365 Development in Derry — common questions
- Why does registration stage matter?
- Because it determines what data you can see and change. Running before the operation lets you modify values as part of the same save; running after means the record is already written and changing it requires a second update — with different performance and different failure behaviour.
- What is wrong with calling an API synchronously?
- Your form now depends on someone else's uptime. A synchronous step waits inside the transaction with a limited window, so any slowness in the external service becomes users unable to save. Queue the work and let the save complete.
- How do plug-ins cause loops?
- By updating the table they are registered on, which fires the plug-in again. The platform will stop runaway depth, but the symptom is confusing and the correct fix is checking the depth or filtering on the specific attributes that should trigger the logic.
- When should we use Azure instead?
- For anything long-running, heavy or genuinely external. Pushing work to a function or queue keeps the platform responsive and puts the logic somewhere you can scale and monitor properly — plug-ins are best kept small and close to the record.
- Do you work with businesses across County Londonderry?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout Northern Ireland, including Derry and the surrounding County Londonderry area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Derry businesses do you usually work with?
- Cross-border trading systems for businesses working into Donegal, and manufacturing tooling for the north west. Beyond that we work across Manufacturing, Healthcare, Higher Education, Digital and Tourism.
- Do you cover the areas around Derry?
- Yes — we work throughout Northern Ireland, including Belfast, Lisburn. Derry is an urban area of roughly 85,000+, and we take on work across the wider County Londonderry region rather than the city boundary alone.
