Custom applications, integrations and SPFx web parts for SharePoint Online and Microsoft 365. We design before we build, stay Microsoft-native wherever possible, and deliver everything inside your environment – no external hosting, no third-party dependencies.
Typical contained builds run three to eight weeks.
What we build
SPFx web parts and extensions, custom business applications, integrations with line-of-business systems, and increasingly agents built on Copilot Studio.
How we start
Never with technology. Requirements and process first, workflow mapped, wireframed and signed off before any development begins.
Where it runs
Inside your Microsoft 365 tenant. No external hosting, no third-party dependencies, no data leaving your environment.
How long
Three to eight weeks for a contained build, quoted as a fixed price against an agreed scope.
Three kinds of work, and most projects involve more than one.
Custom themes, mega-menus and layout extensions that take an intranet beyond what site settings allow. This is where SPFx earns its place - the modern page editor is genuinely good now, but it stops short of a navigation model designed around how your organisation actually works.
SharePoint integrations connecting lists and document libraries to the systems your business already runs - CRM, ERP, HR, finance, ITSM. Custom connectors where a standard one does not exist, and Microsoft Graph where the data is already inside Microsoft 365.
Interactive dashboards, resource and room booking, structured approval processes, read-tracking for compliance. The applications that do not exist off the shelf because they are specific to how you work.
Increasingly this work means agent development - Copilot Studio, custom connectors feeding Copilot, and retrieval over your own content so answers come from your material rather than the open web. More on AI & search.
The question worth asking a development partner, and the one most avoid answering.
Power Apps and Power Automate cover a great deal, and where they fit we use them – it keeps the solution inside licensing you already hold and inside a support model your own team can pick up. Three things push a requirement past low-code, and it is usually obvious which one you are hitting.
Power Apps gets you a working interface quickly, within its own interaction patterns, and embedded in a SharePoint page it always reads as a separate application sitting inside one. That is fine for a form somebody completes occasionally.
It is not fine when the experience genuinely matters - a tool used fifty times a day, or something that has to feel like part of the intranet rather than a visitor to it. Where the UX needs designing rather than assembling, SPFx gives us control over layout, interaction and page integration that a canvas app cannot.
SharePoint lists are flat, with lookups. That works well up to a point. Past a certain number of related entities you are working around the platform rather than with it, and the workarounds are what later becomes unmaintainable.
Where the requirement is a real relational database - multiple related tables, referential integrity, joins, volume - that belongs in a SQL database in Azure, with SPFx over the top for the interface.
Dataverse sits between the two and is a reasonable fit for straightforward builds. Our experience is that a requirement which has genuinely outgrown SharePoint lists usually warrants the full step rather than an intermediate one, so in practice we go from lists to SQL.
Power Automate is built for orchestration - move this, notify them, wait for approval. It is not built for computation, and at volume the run limits and timeouts stop being a technicality and start being the reason a process fails at month end.
Where there is high compute or intensive processing involved, that work moves to Azure components and the flow calls out to them rather than attempting it inside the platform.
In practice it is rarely one or the other. Most builds that cross any of these lines end up as a mix of SPFx and Azure – SPFx for the interface and the page integration, Azure for the data or the processing behind it, and Power Platform still doing the parts it does well.
Where the answer is Power Apps or Power Automate rather than custom development, that is a different conversation with a different shape.
Because we build Microsoft-native wherever possible, a good deal of what we deliver can be maintained by the people who own the process rather than by us. Process owners adjusting their own Power Automate flows. A key user managing an app that supports their team’s work.
That is deliberate, and it means less ongoing support is needed than a comparable custom build would demand. Where you do want support, our SharePoint support services cover the solutions we have built.
Handing something over only works if it is governed. Environments, permissions, naming conventions, ownership and a review cycle all need to exist before a maintainable solution becomes somebody else’s problem – and governance is a service we sell, implement and advise on rather than an assumption we leave you to manage.
If your project sits in the right-hand column we will say so early and point you somewhere better.
On the last two
Several firms on this market sell SharePoint developers by the day, and for some organisations that is genuinely the right purchase. It is not what we do. We take responsibility for the outcome rather than for the hours, which means we scope tightly and turn work down when the fit is wrong.
Tell us what is not working and we will tell you whether it needs custom development at all. If configuring what you already own would do it, that is a shorter and cheaper conversation – and we would rather have it now than three months in.
SharePoint development services cover building tailored web parts, extensions, applications and integrations for SharePoint Online, most commonly using the SharePoint Framework – SPFx – with TypeScript, React and REST APIs. The work bridges the gap between what Microsoft 365 does out of the box and what an organisation actually needs: custom branding and navigation beyond site settings, integrations with line-of-business systems, and business applications that do not exist off the shelf. Increasingly it also covers agent development on Copilot Studio and extending Copilot over an organisation’s own content.
The SharePoint Framework is Microsoft’s supported model for building client-side web parts and extensions that run inside modern SharePoint pages. It matters because it is the option that stays inside your tenant and inside Microsoft’s own support boundary – the code runs in SharePoint rather than on infrastructure somebody else owns. Older approaches, and some third-party alternatives, put parts of your intranet outside your environment. We stay as close to SPFx as the requirement allows for exactly that reason.
Three to eight weeks for a contained build – a web part, an integration, or an application supporting a single process. That range assumes the requirement is understood before development starts, which is why we wireframe and get sign-off first. Larger programmes are scoped in phases rather than quoted as one number, and if a supplier gives you a timeline before understanding the process, the timeline is a guess.
Often Power Apps or Power Automate will do it, and where that is true we will say so – it keeps the solution inside licensing you already hold and lets your own team maintain it. Three things push a requirement past low-code. If the user experience has to be designed rather than assembled, that points to SPFx. If the data is genuinely relational – multiple related tables, referential integrity, volume – that points to Azure with SPFx over the top. And if there is high compute or intensive processing involved, Power Automate is the wrong tool because it is built for orchestration rather than computation. Most builds that cross one of those lines end up as a mix of SPFx and Azure. The honest version of this answer costs us work fairly regularly, which is the point of giving it.
Inside your Microsoft 365 tenant. No external hosting, no third-party services in the path, and no data leaving your environment. Where additional processing or AI capability is genuinely required we use Azure components, still within your subscription. This matters more than it sounds: it means your IT and security teams keep control, and there is no supplier-owned infrastructure to unpick if you decide to work with somebody else.
