Accountancy practices run on deadlines, client trust and software that has to work. When a system goes down in the last week of January, or a client's financial records end up in the wrong inbox, the cost isn't just technical. That's why our IT support for accountants is built around how a practice actually works, not a generic package for any office.

We look after accountancy firms across Cardiff, South Wales and the UK, from sole practitioners to multi-office practices, keeping your systems secure, your software running and your team able to work from anywhere.

IT That Keeps Pace with the Accountancy Calendar

Your busiest weeks are the worst possible time for IT problems. In the run-up to the 31 January self-assessment deadline, every hour of downtime means work piling up and clients waiting. We plan updates, upgrades and changes for quieter periods, and monitor your systems so problems are spotted before they hold your team up.

Making Tax Digital is also spreading the workload across the year. Since 6 April 2026, sole traders and landlords with qualifying income over £50,000 have had to keep digital records and send quarterly updates to HMRC, and the threshold falls to £30,000 in April 2027 and £20,000 in April 2028. More clients on digital reporting means your practice relies on its cloud accounting software and connectivity every week, not just at year end.

Protecting Your Clients' Financial Data

Accountancy firms hold exactly the information criminals want, and fake HMRC emails and payment-change scams target practices directly. We protect your practice with:

  • Multi-factor authentication on every account, so a stolen password isn't enough
  • Email filtering that catches phishing and spoofed HMRC messages
  • Encrypted laptops and phones, with remote wipe if a device is lost
  • Secure ways to share files with clients, instead of email attachments
  • Backups that are checked and tested, not just assumed to work
  • Practical security awareness for your team

Clients and insurers increasingly ask for Cyber Essentials. With CCSW Cyber Secure, we handle your certification every year, with monthly scanning and penetration testing in between.

Support for Accounting and Tax Software

We keep the computers, network and Microsoft 365 your software depends on running smoothly, and deal with the vendor on your behalf when something goes wrong. That includes:

What Our IT Support for Accountancy Firms Includes

All for a fixed monthly fee per user, so your IT costs stay predictable, even in busy season.

For Practices of Every Size

For a sole practitioner or a small practice, we act as your whole IT department, so you can focus on clients rather than computers. Our small business IT support explains how that works for smaller teams.

For multi-office firms, we standardise systems across every branch, centralise data securely and give each office the same reliable setup. If you already have an IT person, we can support them rather than replace them. And if you're thinking of changing provider, here's what actually happens when you switch.
