Microsoft 365 comes out of the box with more tools than most staff will ever touch. The gap between owning the licence and actually running a digital workplace that people enjoy using is where a good consultancy earns its fee.
That gap looks different for every business. Some need someone to untangle a messy SharePoint migration. Others want automation built around Teams and Power Platform, or a partner who can wire up Copilot without breaking existing workflows. Below are six firms working in this space, each with a different focus worth knowing about before you shortlist anyone.

Best for SharePoint-Led Digital Workplaces – Silicon Reef
Silicon Reef is a Microsoft Solutions Partner for Modern Work, working across the Microsoft 365 ecosystem with SharePoint as the base layer. That includes Viva for engagement, Power Platform for automation and Copilot for AI-driven productivity, all built around the idea that a digital workplace only works if people actually use it.
The firm specialises in SharePoint design, SharePoint intranets and workflow automation. Its work includes intranets, employee portals, document management systems, web apps and event management platforms, combining Microsoft 365 expertise with solutions designed around how employees work day to day.
Custom AI assistants built with Copilot Agents can automate tasks and connect systems, with Silicon Reef positioning them as a practical way to deliver measurable impact quickly rather than focusing only on proof-of-concept experimentation.
The firm’s own framing is people-first, connecting technical delivery with business goals so Microsoft 365 solutions improve adoption, engagement and everyday processes. That makes Silicon Reef particularly relevant for organisations focused on improving adoption, modernising an underused intranet or making document management easier and more trusted across the business.
Best for Broad Digital Transformation Support – Intelogy
Intelogy positions itself as a UK Microsoft Consultancy and Digital Transformation partner, covering Microsoft 365, Copilot, Power Platform and Azure under one roof. Its service lines run from Teamwork and Employee Experience through Knowledge and Information Management, Business Applications and Insights, Cloud Platform and Security, Cloud Managed Services and Microsoft 365 Migrations.
That breadth is the appeal for a business that wants one partner covering everything from a Microsoft 365 migration to ongoing Azure security, rather than juggling several specialists. Intelogy carries a rating of 4.9 on Cloudtango, a solid signal for a consultancy of its size. The trade-off with a generalist scope this wide is that a deep, SharePoint-specific intranet build may get less dedicated focus than it would from a narrower specialist.
Best for General Technology Consulting – GraVoc
GraVoc is a technology consulting company built around finding technology solutions for a business, without pinning itself to one platform or product line. That generalist stance suits a company that isn’t sure yet whether its problem is a Microsoft 365 issue, an infrastructure issue or something else entirely and wants a consultant to diagnose first.
The catch is that broad positioning cuts both ways. A firm built for finding solutions in general terms won’t carry the platform-specific depth that a Microsoft 365 specialist brings to a SharePoint or Copilot rollout, so it suits early-stage diagnosis better than a deep, single-platform build.
Best for Everyday IT Support – Plow Networks
Plow Networks delivers customised IT solutions for businesses, with network support, cloud support and technical support under one service umbrella. It reads as an IT services partner first, useful for a business that wants its network, cloud and day-to-day technical support handled by a single provider rather than split across vendors.
Because the offer centres on general IT and network support rather than a named collaboration platform, it fits a business looking for infrastructure and helpdesk continuity more than one hunting for deep SharePoint or Teams design work.
Best for Dynamics 365 Automation – Avantiico
Avantiico is a Microsoft Solutions Partner and consulting firm built around ERP, consulting and automation integrations native to Dynamics 365. That focus makes it a sensible call for a business whose priority is connecting Dynamics 365 to wider automation, rather than building out a SharePoint intranet or employee portal.
Its scope leans toward Dynamics 365 and ERP-adjacent automation specifically, so a business hunting for a broader Microsoft 365 workplace overhaul will find the fit narrower than what a Microsoft 365-wide consultancy offers.
Best for Managed Cloud Communications – Fusion Connect
Fusion Connect describes its core business as cloud communications and managed services, covering business communications, secure networks and hosted collaboration tools. It’s built for a company whose main need is reliable phone systems, networking and hosted collaboration infrastructure rather than a Microsoft 365 or SharePoint project specifically.
That communications-first focus means it suits a business prioritising uptime on calls and networks, with less emphasis on the kind of intranet or workflow design work a SharePoint specialist handles.
What to Compare Before You Commit
Not every consultancy on this kind of list solves the same problem, so the comparison isn’t really about picking a winner. It’s about matching the firm’s actual specialism to the problem sitting in front of you.
Start with scope. A generalist IT provider and a platform specialist both call themselves Microsoft partners, but one is set up to fix a broken laptop fleet and the other is set up to redesign how three hundred people find a document. Ask what the engagement actually covers: is it a one-off migration, an ongoing managed service, or a build-and-adoption project that needs someone in the room for months after go-live?
Adoption is the part businesses underestimate. A technically flawless SharePoint site that nobody logs into has delivered nothing. Firms that talk about employee experience and usability alongside the technical build, rather than the technical build alone, tend to plan for that problem rather than discovering it six months post-launch. If your organisation is exploring how AI agents fit into a modern operations stack, the same logic applies: the tooling matters less than whether staff actually adopt it.
Finally, check where automation sits in the pitch. Some consultancies bolt Power Automate flows on as an afterthought. Others, working with the fuller Power Platform toolset, treat automation and AI assistants as core to the build from day one. That distinction tends to predict how much value you see in the first year versus the third.
Which One Is Right for You
The right partner depends on what’s actually broken. If the problem is general IT infrastructure, Plow Networks or GraVoc cover that ground. If it’s Dynamics 365 automation specifically, Avantiico is the narrower, more relevant fit. If communications and hosted collaboration are the pain point, Fusion Connect is built for that. And if you want one partner spanning the full Microsoft 365 and Azure stack with a strong review track record, Intelogy’s breadth and its 4.9 rating on Cloudtango make a solid case.
For a business whose real challenge is getting people to actually use SharePoint, Viva and Copilot together, rather than just having them switched on, Silicon Reef’s SharePoint specialism and its focus on adoption and usability edge it out as the strongest match. It’s the pick for an organisation that already knows the technology isn’t the hard part. Getting people to change how they work is.
