IT for Accountancy Firms: Surviving Deadline Season Without Downtime

For an accountancy practice, an outage in late January is not an inconvenience, it is a compliance risk with penalties attached. Everything about your IT should be judged on how it behaves during your busiest fortnight.

The business impact

Practices concentrate enormous value into short windows: self assessment, year end, payroll runs, VAT quarters. Downtime, a slow remote session or a locked out account during those windows costs chargeable time you cannot recover, and it lands directly on client relationships.

Five priorities for a practice

1. Size your systems for peak, not average. If your remote desktop crawls when fifteen people are in it at once, that is the number that matters, not how it feels in June. Load test before the season, not during it. The same applies to internet capacity if your practice software is cloud hosted.

2. Treat MFA and email security as fraud prevention. Accountants are prime targets for invoice redirection and payroll diversion attempts, because criminals know you hold bank details for dozens of businesses. Enforce multi factor authentication, add anti impersonation protection for partner mailboxes, and train the team to verify any change of bank details by phone.

3. Get client data exchange off email attachments. Sending tax returns and payroll reports as email attachments is both a security risk and a version control mess. Use a secure client portal or a properly permissioned Microsoft 365 sharing setup with expiry dates on links.

4. Know your recovery time before you need it. Ask a specific question: if the server or practice software host failed at 9am on 28 January, how many hours until we are working again, and how much work would we lose? If nobody can answer, your continuity plan is a hope. Document a plan, then test it out of season.

5. Keep licences and leavers under control. Practices grow and shrink with seasonal staff. Every temporary account is a live risk once the season ends. Automate the leaver process, review licences quarterly, and stop paying for people who left in March.

Compliance points that are really IT points

• UK GDPR: encryption on all devices, retention rules on client data, and a documented breach response.
• Anti money laundering records: secure, tamper resistant storage and retrieval of identity documents.
• Making Tax Digital: reliable, supported software and a stable connection to HMRC services.

None of these are paperwork exercises. They are configuration decisions your IT partner should be making with you.

The Orange Penguin take

We plan accountancy support around the calendar. That means change freezes during deadline season, capacity checks before the rush, proactive monitoring so problems get caught overnight, and a support arrangement where partners are not waiting in a queue on the twenty ninth of January.

Fixed monthly pricing matters here too. Practices under seasonal pressure should never be hesitating to raise a ticket because it might be chargeable.
