Virtual Cabinet has been a staple of UK accounting for over 20 years. Based in Cambridge, trusted by thousands of firms, and deeply embedded in the market. If you’ve worked in UK practice, chances are you’ve encountered it.

But the way UK firms work is changing. MTD for Income Tax is going live in April 2026. Firms are modernising their tech stacks, moving to the cloud, and rethinking whether their existing tools are built for what’s ahead.

If you’re evaluating your document management options, here’s an honest comparison.

The Short Version

Virtual Cabinet was built for how UK firms worked a decade ago. SuiteFiles is built for how they work today.

SuiteFiles is a modern, cloud-native workspace built on Microsoft 365. It brings document management, email management, a branded client portal, unlimited e-signatures, PDF tools, and workflow automation together in one place, from just £25/user/month. Your data stays in your own Microsoft 365 environment, and your team can be up and running in weeks.

Where SuiteFiles Stands Out for UK Firms

Your Data, in Your Microsoft Tenancy

For UK firms navigating GDPR, client confidentiality obligations, and increasing scrutiny around data handling, this is the single biggest difference.

With SuiteFiles, your documents live in your firm’s own Microsoft 365 environment, hosted in Microsoft’s UK data centres if you choose. You own it. You control it. If you ever leave SuiteFiles, your files stay exactly where they are.

Virtual Cabinet stores your data on their proprietary servers. Your documents sit in their infrastructure, not yours. For any firm that’s had to answer a client’s question about where their data is held, that distinction matters.

Built for Firms Running IRIS, CCH, and Xero

Most UK accounting firms run IRIS or CCH as their core practice management platform. The document management modules built into those systems handle the basics, but they weren’t designed to manage how work actually moves from start to finish.

SuiteFiles sits alongside your practice management and handles what their embedded document tabs were never built to do: email filing, client portals, e-signatures, PDF editing, templates, and workflow automation. It doesn’t replace your practice management software. It completes it.

One Workspace, Not a Patchwork of Tools

UK firms typically end up stitching together separate tools for document storage, signing, client file requests, and PDF editing. Each one has its own login, its own invoice, and its own learning curve.

SuiteFiles brings all of that together natively. Document management, email filing, client portal, unlimited e-signatures, PDF tools, templates, and task management in a single platform. Fewer tools. Fewer invoices. Less admin.

More Platform, Less Cost

SuiteFiles plans start from £15/user/month for document management, email filing, and PDF tools. At £25/user/month, you get the full workspace: everything above plus a branded client portal and unlimited e-signatures.

Virtual Cabinet’s Workiro starts at ~£20/user/month for signing functionality alone. So for £5 more than Workiro’s signing-only tier, SuiteFiles gives you signing, a client portal, document management, email filing, PDF tools, templates, and workflow automation.

SuiteFiles publishes its pricing. You know what you’re getting and what it costs before you speak to anyone. No “request a quote,” no negotiation games.

Built on What Your Team Already Knows

SuiteFiles is built on Microsoft 365. Your team already uses Word, Excel, PowerPoint, and Outlook every day. SuiteFiles adds structure, workflow, and collaboration on top of that familiar foundation. That means faster adoption and less resistance from the team members who just want to find a document and get on with their work.

Virtual Cabinet’s interface is separate from your existing Microsoft tools. For teams already invested in the Microsoft ecosystem, that’s an extra learning curve your firm doesn’t need.

MTD-Ready Workflows

With Making Tax Digital for Income Tax launching in April 2026, UK firms are under pressure to tighten their digital processes. SuiteFiles helps by ensuring every client document, email, and deliverable is organised, version-controlled, and audit-ready in one place, exactly the kind of digital foundation MTD demands.

Where Virtual Cabinet Has Strengths

We believe in being straightforward. Here’s where Virtual Cabinet holds ground:

  • Deep roots in UK accounting. Over 20 years of serving UK practices. They understand the market, and many firms have long-standing relationships with their team.
  • Workiro’s structured workflows. Their newer Workiro product offers purpose-built onboarding workflows and recurring task templates designed around client work cycles.
  • 98.4% support satisfaction. They’ve built a strong reputation for responsive customer support.
  • 65,000+ professionals. A large installed base across UK regulated firms, particularly in accounting, insolvency, and advisory.

The Real Question for UK Firms

If your firm is growing, modernising, or simply tired of a system that feels like it belongs to a different era, the question isn’t whether Virtual Cabinet worked in the past. It’s whether it’s built for what’s next.

Firms across the UK are moving away from legacy document management towards modern, cloud-native workspaces that give them control over their data, reduce their tool sprawl, and help their teams work the way they already want to: in Microsoft 365, with everything in one place.

That’s the conversation SuiteFiles is built for.

Who Is SuiteFiles Best For?

SuiteFiles is ideal for UK firms that:

  • Use (or plan to use) Microsoft 365
  • Run IRIS, Karbon, or Xero as their practice management platform
  • Want full ownership and control of their data in UK data centres
  • Need document management, signing, client portal, and email filing in one platform
  • Are preparing for MTD and need tighter digital workflows
  • Value fast implementation without months of IT disruption
  • Want transparent pricing from £15/user/month, with the full workspace at £25/user/month

Who Might Prefer Virtual Cabinet?

Virtual Cabinet may suit firms that:

  • Are deeply embedded in Virtual Cabinet’s ecosystem and not planning to change
  • Prefer an on-premise or hybrid deployment model
  • Are primarily looking for a signing and document collection tool (Workiro’s entry tier)

Firms That Made the Switch

Accounting practices across the UK and beyond have migrated from Virtual Cabinet to SuiteFiles. Common reasons they share:

  • “We wanted something modern.” The legacy interface was creating friction, especially for newer team members who expected a more intuitive experience.
  • “We needed everything in one place.” Managing separate tools for signing, portals, and document storage was costing time and money that could be spent on client work.
  • “Data ownership was non-negotiable.” Knowing their files live in their own Microsoft tenancy, in UK data centres, gave them the confidence and control they needed.
  • “The migration was painless.” SuiteFiles handled everything, and the team was productive from day one.
