Custom SharePoint Development & SPFx Solutions
When out-of-the-box SharePoint is close but not quite there.
We build custom solutions on SharePoint using the SharePoint Framework (SPFx): web parts, page and list extensions, dashboard cards and business apps backed by SharePoint lists, Microsoft Graph and your own APIs. We also replace SharePoint Add-ins, which Microsoft retired in SharePoint Online in April 2026, with supported SPFx and Power Platform solutions.

When standard SharePoint is not enough
“Our add-in stopped working.”
SharePoint Add-ins reached end of life in April 2026, and solutions built on them need replacing.
“We need a view the standard web parts can’t show.”
Project trackers, KPI dashboards and custom forms need more than list views.
“Our process spans SharePoint and three other systems.”
Users switch between apps because nothing brings the data together.
Custom SharePoint solutions
Built with Microsoft’s supported, upgrade-safe development model.
SPFx web parts
Dashboards, trackers, directories and forms as reusable web parts on any page.
Extensions & list customisation
Application customisers, field and command set extensions, and list formatting.
Add-in replacement
Retired SharePoint Add-ins and classic customisations rebuilt with SPFx, Power Apps or Power Automate.
Graph & API integration
Data from Microsoft Graph, Dataverse, Business Central or your APIs shown in SharePoint.
Copilot-ready solutions
Solutions that work with Copilot and agents, using SPFx Copilot UI components where relevant.
Code quality & handover
Source control, automated builds, documentation and admin handover.
The SharePoint developer platform in 2026
Recent changes to the platform affect every custom solution:
- SharePoint Add-ins retired in SharePoint Online on 2 April 2026; SPFx is Microsoft’s recommended replacement
- SPFx 1.24 adds Copilot UX components, React 18 and a modern Heft-based build toolchain
- Hosted workbench retiring in December 2026, replaced by the SPFx debug toolbar, so development practices need updating
- Agents and Copilot can work alongside custom solutions that keep data in well-structured lists and libraries
Some Microsoft features need specific licences or pay-as-you-go billing. We confirm what your plan includes before we design around it.

SharePoint development questions, answered
Plain answers to what business owners ask before they start.
Ask us a questionWhat is SPFx?
The SharePoint Framework is Microsoft’s supported model for custom web parts and extensions in SharePoint Online, Teams and Viva Connections. It replaces older approaches such as add-ins.
Our SharePoint Add-in stopped working. What now?
SharePoint Add-ins are retired in SharePoint Online. We analyse what the add-in did and rebuild it with SPFx, Power Apps or Power Automate, whichever is simplest to maintain.
Should we build custom code or use Power Apps?
Power Apps is faster for many forms and simple apps. SPFx suits richer experiences, performance-sensitive pages and deep integration. We recommend the lighter option where it works.
Who owns the code?
You do. Source code is delivered to your repository with documentation and deployment instructions.
Will the solution survive SharePoint updates?
SPFx solutions use supported APIs and are designed to be upgrade-safe; our support plans include updates for platform changes.
Can it connect to Business Central or Dynamics 365?
Yes. Web parts can display and update data from Business Central, Dataverse and other systems through their APIs.
