In short
Dig IT Solutions provides managed IT support for accountancy practices across Hertfordshire, west Essex and London. We keep tax and practice software such as IRIS, CCH, Sage and Xero running, secure Microsoft 365 and HMRC agent services logins with MFA, back up client data and staff the helpdesk through January and year-end. It suits firms of 5 to 80 people without their own IT department.
Who this is for: Independent and regional accountancy practices of roughly 5 to 80 staff: ICAEW and ACCA member firms, bookkeeping and payroll bureaus, and multi-partner practices with a second office. Our day-to-day contact is usually the managing partner, the practice manager or whichever partner has ended up owning IT.
Sector pressures
What keeps accountants up at night
January and year-end leave no room for downtime
The 31 January self-assessment deadline, company year-ends, VAT quarters and weekly payroll runs mean the calendar decides when you can afford a fault, and the answer is never. A lost day in late January is lost fees and missed filings, with penalties your clients will expect you to explain.
The HMRC agent services account is your most valuable login
One set of credentials reaches every client's tax records, and the phishing that targets it peaks when HMRC emails are expected. Shared logins, weak MFA or an unprotected mailbox receiving access codes put the whole client base at risk. Identity security matters more here than in almost any other small business.
Making Tax Digital and a growing cloud stack
MTD for VAT and, from April 2026, MTD for Income Tax mean more clients on Xero, QuickBooks and Sage, more bridging tools and more browser-based apps per fee-earner. Each one is a separate identity to protect and a separate integration to keep working, so the practice's security perimeter is now its user accounts rather than its office.
Client data under UK GDPR and the AML regime
A practice holds passports, bank statements, payroll records and personal tax affairs for hundreds of clients, and the Money Laundering Regulations require due diligence records to be kept securely for years. One breach touches every client at once, so encryption, retention rules and a secure document portal instead of email attachments are the practical controls.
Practice software on an ageing server
IRIS, Sage 50 and CCH Central often sit on a Windows server bought years ago, with a SQL database nobody has restored from backup and remote desktop open to the internet. When that server reaches end of support the choice is a replacement, a hosted edition or the vendor's cloud product, and it needs planning outside the busy season.
What we do
How we support you
A helpdesk built around your filing calendar
Remote support via Splashtop fixes a frozen tax return in minutes, and on-site engineers from Hoddesdon handle hardware and network faults. We schedule updates and server work around your deadlines and hold a change freeze in the last two weeks of January.
MFA and conditional access for HMRC and Microsoft 365
Every user gets MFA, conditional access limits sign-ins to managed devices and expected locations, and shared HMRC logins are replaced with named access. We secure the mailbox that receives HMRC codes as carefully as the account itself.
Practice software kept current and recoverable
Server patching through our remote monitoring and management platform, IRIS, Sage and CCH version upgrades scheduled with the vendor, SQL backups verified by restore, and a costed plan for moving to hosted or cloud editions when the server needs replacing.
Backups you can prove to a client or regulator
Local and cloud backups of servers and file stores, Microsoft 365 backup for mailboxes, OneDrive and SharePoint, and periodic test restores with written reports. If a member of staff deletes a client folder in March, we bring it back rather than rebuilding it.
Email security and awareness training for HMRC-themed phishing
Filtering that catches HMRC and client impersonation, DMARC on your own domain so it cannot easily be used against your clients, and short, regular security awareness training timed for the run-up to January when the fake refund emails arrive.
Growth handled: starters, hardware and phones
HP or Dell laptops with dual screens imaged and ready before a new trainee starts, new-starter and leaver forms through the client portal, and 8x8 VoIP with call queues so client calls are answered in busy weeks rather than bouncing to voicemail.

Compliance and expectations
HMRC agent services and Making Tax Digital
HMRC's agent services account and MTD-compatible software give a practice direct access to client tax records, so HMRC expects agents to protect those credentials. For IT that means MFA everywhere, no shared logins, secured mailboxes for verification codes and prompt removal of access when staff leave.
HM Revenue & CustomsUK GDPR and the ICO
Client identity documents, bank details and tax records are personal data that must be protected and retained only as long as needed. A breach affecting clients must be assessed and, where required, reported to the ICO within 72 hours, which needs logging and a provider who can establish what happened.
Information Commissioner's OfficeCyber Essentials
Professional bodies, insurers and larger clients increasingly ask practices whether they hold Cyber Essentials. Its five controls, from patching to access control, are what we operate anyway, so preparation is mostly closing exceptions and writing down what is already true.

Switching to us
How the handover works
We do not move accountancy practices in January or the week of a payroll run. Switching starts with a discovery visit to record every application, server, licence, HMRC login and integration, followed by documentation your practice manager can actually read. We run in parallel with your current provider through handover, migrate quietly in a chosen quiet week, and brief staff before anything changes on their desks. The step-by-step process is at our switching IT provider guide.
