Microsoft 365 consultancy built for growing organisations

Large Microsoft partners are structured around enterprise accounts. Inspizer is structured around organisations with 50 to 500 users — where Microsoft 365 has become complex, the IT team is stretched, and the right specialist engagement makes a measurable difference.

Organisations at this scale have real Microsoft 365 complexity — but don't need an enterprise consultancy. They need a specialist who works at their size.

Who we work with

The organisations that get the most from Inspizer

Inspizer works with professional services, legal, financial, property, and technology businesses that share a common situation: they are using Microsoft 365, it has grown complex, and the organisation needs expert help to bring it back under control — or to get it properly configured for the first time.

Professional services

Consultancies, accountancies, and advisory firms where client data protection, governance, and team collaboration are business-critical. Microsoft 365 is the platform — Inspizer makes it work properly.

Legal practices

Law firms and barristers' chambers where document management, email security, and compliance are non-negotiable. SharePoint, Exchange Online, and Purview configured to meet regulatory requirements.

Financial services

Financial advisory, wealth management, and insurance businesses where data security, access controls, and audit trails matter. Inspizer implements the controls that protect client and regulatory data.

Property & real estate

Estate agencies, property management firms, and developers who need secure collaboration across sites and teams — with document management that doesn't rely on shared drives and email threads.

Healthcare & life sciences

Private clinics, healthcare providers, and life sciences businesses where data sensitivity requires more than default Microsoft 365 security settings — and where compliance evidence matters.

Technology businesses

Software companies, digital agencies, and IT service providers who need their Microsoft 365 environment to work as hard as they do — properly governed, securely configured, and efficiently licensed.

Why size matters

What scaling to 1,000 users actually means for Microsoft 365

Organisations at this scale face Microsoft 365 challenges that are too complex to fix internally but don't require an enterprise-scale partner. This is the space Inspizer works in.

At 50 to 100 users, Microsoft 365 typically works — but it has been configured by whoever set it up first, not by a specialist. Licences are a mix of what salespeople sold and what felt safest. Security defaults are on, but Conditional Access has never been touched. SharePoint is a dumping ground, not an information architecture.

At 100 to 300 users, the problems compound. Teams has proliferated. SharePoint permissions are inconsistent. Guest access has never been audited. The Microsoft Secure Score is low but nobody knows why. Someone mentions Cyber Essentials but nobody has time to deal with it.

At 300 to 500 users, the organisation is large enough that Microsoft 365 governance failures create real risk — but still too small to justify the overhead of a large systems integrator or a full-time Microsoft specialist. This is where Inspizer delivers the most value.

The engagements are right-sized: a fixed scope, a clear outcome, and documentation your IT team can maintain. No enterprise-scale project management, no unnecessary complexity — just the work that needs doing, done properly.

Common situations

When organisations call Inspizer

Making the right choice

Inspizer versus the alternatives

vs. a large Microsoft partner

Large partners are structured for enterprise accounts. They have account managers, project managers, and junior delivery teams. For a 150-user organisation, that structure adds cost and complexity without adding value. Inspizer delivers the same technical depth without the enterprise overhead.

vs. your internal IT team

Internal IT teams are generalists — they keep everything running. Microsoft 365 architecture, governance, and security configuration are specialisms. Inspizer supplements your internal team with deep Microsoft 365 expertise for the engagements that require it.

vs. a managed service provider

MSPs provide ongoing support — Inspizer provides specialist project delivery. If your MSP doesn't have deep Microsoft 365 expertise in-house, Inspizer can work alongside them as the specialist layer for complex migrations, security programmes, and governance projects.

FAQs

Frequently asked questions

Do you work with organisations outside London?

Yes. Most of Inspizer's work is delivered remotely — configuration, migration, security, and governance work does not require on-site presence in most cases. For engagements where on-site work is necessary (complex cutover migrations, Exchange certificate renewals), Inspizer is available across London and the South East and can travel further for the right engagement.

Is there a minimum organisation size?

There is no formal minimum. In practice, the organisations that benefit most from Inspizer's work have between 50 and 500 Microsoft 365 users — enough complexity to make specialist help worthwhile, but not so large that they need an enterprise partner structure. That said, smaller organisations with complex environments are also welcome to enquire.

Do you work with organisations that already have an IT support provider?

Yes — most Inspizer clients already have an IT support company or internal IT function. Inspizer works alongside them as a Microsoft 365 specialist for projects that require deeper expertise than a generalist MSP typically carries. We document everything so your existing IT team can maintain the configuration after the engagement ends.

What sectors do you have most experience in?

Inspizer has delivered engagements across professional services, legal, financial services, property, healthcare, and technology businesses. The Microsoft 365 platform is largely sector-agnostic — the governance, security, and migration challenges are similar across industries. Where sector-specific compliance requirements exist (FCA, GDPR, NHS data handling), Inspizer incorporates those into the scope.
