Tenant and site review
A written review of your sites, lists, permissions, and retired add-ins, with rebuild priorities in order.
The Problem
Your Intranet Exists, but Nobody Can Find Anything on It
It shows up when a policy can't be found, a form stops working, or IT can't say who has access to which folder. By then the workarounds have their own workarounds.
01 · Lost files
The same document lives in several department libraries.
A hub site with shared navigation gives each document one clear home.
02 · Dead add-in
An old add-in stopped when Microsoft retired the model.
We rebuild it as an SPFx web part on supported code.
03 · Email approvals
Approvals travel by email and get tracked in a spreadsheet.
Power Automate flows route approvals and log every decision on the list.
04 · Unclear access
Permissions were granted one person at a time.
Access is set by group and department, so it's easy to review.
Your intranet was built years ago, and nobody can find the leave policy on it. Each department made its own site, so the same document lives in several libraries. An old add-in that ran your request form stopped working when Microsoft retired the add-in model. Approvals still travel by email, and someone tracks them in a spreadsheet beside a SharePoint list. Permissions were granted one person at a time, so nobody knows who can see what.
We start with a tenant review: your sites, lists, permissions, and anything still running on retired add-ins or workflows. Then we plan a clear site structure, build SPFx web parts for what out-of-box parts can't do, and move approvals into Power Automate. Permissions are set by group, not by person. Your team opens the intranet because the answer is actually there.
SPFx web parts that fit
Custom web parts built with the SharePoint Framework, Microsoft's recommended model for SharePoint Online.
Permissions set by group
Access planned per department and role, so the right people see the right files.
Findable by design
Clear hub navigation, page templates, and metadata, so documents turn up where people look first.
Our SharePoint Development Services Process
From Free Tenant Review to a Live Intranet in Five Steps
You approve the site map and the access model before anything changes in your tenant, then a pilot group from each department tests the result.
We review your sites, lists, permissions, and any add-ins or workflows still in use. You get a plain list of what out-of-box SharePoint covers, what needs SPFx, and what needs rebuilding first.
What's Included
What You Get With SharePoint Intranet Development
A tenant review, a site and permission plan, SPFx web parts, list-based apps with Power Automate, rebuilt add-ins, and admin notes for your IT team.

What Our Clients Say
What Clients Say After Launch
Feedback from teams we have built corporate websites and business apps for.
We had a pretty specific idea of what we wanted our website to become, but I wasn’t sure how easily we could explain all of it to a development team. There were quite a few moving parts, and we were working toward a deadline, so I expected a few things to get lost along the way. That never really happened. They understood what we were trying to achieve, kept us updated throughout the process, and got everything ready within the agreed timeline. The final site feels much easier to navigate, works beautifully on mobile, and is noticeably smoother for our customers. It was a huge relief seeing the original idea actually turn into the website we had in mind.
The mobile experience is probably my favourite part of the new site. We had spent a lot of time making sure the desktop version looked right, and the team kept pushing us to think about how everything would actually feel on a phone too. They were right. The navigation is clean, the interactions feel natural, and everything we’ve tested so far works exactly as it should. They also went through the links, forms, integrations, and other details more than once before launch, which I really appreciated. And even after going live, we could still reach out when something came up. The whole process felt friendly, organised, and surprisingly straightforward.
What I appreciate most is that the website is actually easy for us to manage now. We can update content ourselves instead of sending a developer a message every time we need to change something small. They also paid attention to the technical SEO side, which mattered to us because we didn’t want a new website to create problems for the traffic we already had. I’ve probably asked more questions than I should have since launch, but every question has been handled patiently and without any fuss. The team is easy to work with, they explain things clearly, and when we need something changed, they focus on getting it done rather than making the process complicated.

Work Culture
Why IT Teams Trust Us Inside Their Microsoft 365 Tenant
Custom code in SharePoint runs inside your tenant, next to every file your company owns. These habits keep it supported, secure, and easy for IT to manage.
Out-of-box features first
Modern SharePoint pages, lists, and web parts handle more than most teams expect. If they already cover your case, we'll tell you before we quote.
Supported code only
Microsoft retired SharePoint Add-ins and 2013 workflows on April 2, 2026. Everything we build uses SPFx and Power Automate, the models Microsoft supports today.
Honest about list limits
A list holds up to 30 million items, but views fail past the 5,000-item threshold unless they filter on indexed columns. We design around that or suggest a database.
Least-privilege Graph permissions
SPFx solutions request only the Microsoft Graph permissions they need. Your admin approves each one, so no web part reads more of the tenant than it should.
Code in your repository
Every web part's source code lives in your Git repository with build notes. Your IT team can rebuild and redeploy it without us.
Admin notes for everything
Each site, web part, and flow gets a short admin note: what it does, who owns it, and what to check after Microsoft updates.

Good fit
Teams hit by retired add-ins
Your old SharePoint Add-ins or 2013 workflows stopped working after Microsoft retired them in April 2026, and you need them rebuilt on supported code.
Companies replacing a dated intranet
Your intranet is a maze of old sites nobody updates, and you want SharePoint intranet development that gives each department one clear home.
Ops teams running work in lists
You track requests in SharePoint lists with email approvals, and want SharePoint application development services that turn them into a proper app.
Firms sharing files with clients
You send clients files as email attachments and want SharePoint portal development that gives each client secure access to their own documents.
IT teams without a developer
Your IT team runs Microsoft 365 well but has no developer, so you want to hire SharePoint developers for SPFx work without adding headcount.
Not a fit
Out-of-box sites cover it
Your need fits standard SharePoint pages, lists, and web parts. Microsoft's built-in site templates cover it faster and cheaper than custom code.
Heavy relational data
Your app needs complex relational data at high volume. A real database fits better than lists, and our Supabase Development page covers that build.
Approval flows only
Your main need is approval flows and automation, not custom code. Our Power Automate Development page covers that work on its own.
SharePoint Server on-premises
Your SharePoint still runs on an on-premises server. This page covers SharePoint Online, so plan the move to Microsoft 365 first.

Send a message or book a call with the team.
Our SharePoint work starts at $1,100 for one SPFx web part or extension, tested on a dev site and deployed through your app catalog. An intranet hub with up to 6 department sites and 3 Power Automate flows costs $3,600. Custom portals with Graph integration and an add-in rebuild start at $7,400. Microsoft 365 licenses stay separate.
One web part takes 1 to 3 weeks, including a pilot with your users. An intranet hub with department sites takes 4 to 8 weeks, and custom portals take up to 10. Content cleanup and permission decisions usually set the pace, so we start them in the first week.
No, not for most sites. Modern SharePoint pages, lists, libraries, and out-of-box web parts need no code at all. Coding comes in with SPFx web parts, extensions, Microsoft Graph integrations, and apps that lists and Power Apps can't handle on their own. We'll tell you which side of that line your request falls on.
It's building custom features on SharePoint Online: web parts, extensions, list-based apps, and integrations with Microsoft Graph. Since Microsoft retired the add-in model, this work runs on the SharePoint Framework and the Power Platform. Good projects also cover site structure and permissions, not just code.
SharePoint Framework development means building web parts and extensions with SPFx, Microsoft's recommended model for customizing SharePoint Online. SPFx solutions run in the page, use modern JavaScript tools such as React and TypeScript, and deploy through the app catalog. They can also appear in Microsoft Teams.
A SharePoint developer builds what out-of-box SharePoint can't: custom web parts, extensions, list apps, and connections to Microsoft Graph or other systems. On our projects, the role also covers site architecture, permission planning, and Power Automate flows. Testing with a pilot group before launch is part of the job.
Yes, for moderate data. A SharePoint list holds up to 30 million items, but views and queries fail past the 5,000-item list view threshold unless they filter on indexed columns. For heavy relational data or complex queries, we'll recommend Dataverse or a real database instead.
Usually not, and that's normal. Administrators manage sites, permissions, storage, and tenant settings, while developers write SPFx code and integrations. The skills overlap on lists and Power Automate. We work alongside your admin, so the code we write fits the way they already manage the tenant.
Hire developers when you have steady SharePoint work and someone to manage them. A company suits a defined project, such as an intranet rebuild or replacing retired add-ins, with a fixed scope and a team for testing. We'll tell you which fits after the free tenant review.
You do. Sites, lists, and flows live in your Microsoft 365 tenant, and every web part's source code goes into your repository. For 30 to 90 days after launch, depending on plan, we handle fixes and questions. Admin notes let your IT team maintain everything once support ends.
