Certified Public Accountants

Frustrated with slow, generic IT support for CPAs?

Your day revolves around tight deadlines, sensitive data, and layers of compliance requirements. Most providers of managed IT services for CPA firms don’t understand that. When your tools crash, updates break key software, or emails go down in the middle of a submission, your whole workflow stalls. 

You rely heavily on Microsoft 365, secure document sharing, and prompt support, especially during tax season and year-end deadlines. 

That’s why our team at Sonar IT works closely with CPA firms in London to deliver fast, specific, and expert IT support for CPA needs.

Practical, secure, and responsive managed IT services for CPA firms

When things go wrong, you need quick, no-fuss support, especially with remote teams, sensitive tax data, and clients depending on your uptime. That’s where our managed IT services for CPA firms come in.

Your firm gets real-time support for critical tools like Xero, QuickBooks, and Sage, with seamless updates that won’t interrupt workflow. Cloud accounting platforms run securely, backed by automated daily backups and ransomware protection. 

Microsoft 365 is set up with proper controls: Intune, Azure AD, and secure user permissions. If your team needs help, you won’t be left waiting. You get direct access to senior engineers who understand how accounting firms work. We also support client portals, encrypted data transfers, and full cyber essentials coverage.

Your compliance software, reporting tools, and payroll systems stay stable and secure. You don’t just get IT support. You get a calm, capable setup that’s built to serve accountants first.

Meeting compliance requirements with the right IT services

Firms like yours juggle strict requirements, from HMRC guidelines to GDPR obligations and ISO standards. You need IT support that understands this space and delivers systems that meet the mark every time.

Our ISO 27001 and ISO 9001-aligned practices help CPA firms stay compliant without unnecessary stress. 

Whether you're navigating MTD, handling confidential financial data, or storing client records securely, we help keep your systems structured, audited, and locked down. Strong IT foundations mean you won’t fall short when it matters most.

Flexible IT support built around CPA firm needs

No two accounting firms run the same way. Whether you’ve got five people in-office or a 40-person team working hybrid, your IT needs to match your setup, not the other way around.

That’s why our managed IT services for CPA firms are never one-size-fits-all. Services are tailored to your daily operations, from secure remote access to automated compliance checklists. 

We help your tools talk to each other, from accounting software to cloud drives, while keeping everything backed up and safe. And as your firm grows, we grow with you, scaling your solutions without adding more hassle.

We’ve seen what works and what doesn’t for CPA firms. That’s what guides the way we support yours.
