An accounting firm has IT that must withstand two things at once: huge spikes in load during filing periods and responsibility for the financial data of many companies at the same time. A failure in a quiet month is a problem. A failure just before a filing deadline is a disaster. That is why an accounting firm’s infrastructure requires a considered approach, not a set of random solutions.

The rhythm of the seasons sets the requirements

The work of a firm is not spread evenly. There are periods when everyone works late, the accounting systems are loaded to the maximum, and every hour of downtime costs real money and nerves. IT has to be prepared precisely for those peaks, not for the yearly average.

What this means in practice:

  • Hardware and connections chosen for peak load, not for a quiet month.
  • Updates and maintenance work planned outside the season, never in the middle of filing.
  • A fast support path in case of a problem during a critical week.
  • A backup internet connection, because a loss of network on filing day stops the whole firm.

With accounting firms I have one iron rule: no changes to the systems at the peak of the season. Updates are done earlier or later, never in the week when everyone is fighting a deadline.

Data you are doubly responsible for

An accounting firm processes the financial and personal data of its clients. That means a double responsibility: towards the law and towards the companies that trusted you. A leak or loss of data hits not only you, but your clients.

The basics worth taking care of:

  • Restricted access to data, so that each employee sees only the companies they handle.
  • Encryption of disks in computers and laptops.
  • Secure exchange of documents with clients, instead of sending everything by unprotected email.
  • Data processing agreements with providers, including the IT company.

Backup, a matter of life and death for the firm

For an accounting firm a backup is not an option, it is a condition of existence. Losing accounting data means a catastrophe: no access to the records of many companies, the risk of missing deadlines, and a loss of trust that cannot be quickly rebuilt.

A solid backup rests on a few principles:

  • The 3-2-1 rule: three copies of the data, on two different media, one off-site.
  • Regular, automatic copies, without relying on an employee’s memory.
  • Test restores, because a copy that has never been checked is only a hope.
  • Protection of copies against ransomware, so an attack does not encrypt them along with the production data.

Email and documents in the cloud deserve separate discussion. Many firms work on Microsoft 365 in the belief that because the data is in the cloud, it is protected. That is an illusion. Microsoft is responsible for the availability of the service, but not for restoring data that someone deleted, overwrote or that fell victim to an attack. That is why it is worth having an independent Microsoft 365 backup that protects email, files and shared mailboxes.

Continuity of work in the critical week

Even the best backup will not replace a plan for a failure. The key question is: how quickly do we get back to work when something goes down. The answer has to be known in advance, not improvised in a crisis.

It is worth agreeing:

  • Which system is the most critical and how long the firm can hold out without it.
  • Who makes decisions in the event of a failure and who needs to be notified.
  • How employees will work if the office or the main system is unavailable.

Where to start

If you want to check whether your IT is ready for the next season, go through a simple list:

  • Does the backup cover all the accounting systems and email, including Microsoft 365?
  • When did we last test restoring data?
  • Do we have a backup connection in case of a network failure?
  • Is access to client data restricted to the right people?
  • Is maintenance work planned outside the peak?

Gaps in any of these points are worth patching before the next rush of deadlines, not during it.

Email and document exchange security

An accounting firm exchanges dozens of documents with clients every month, and email is the main channel of attack. An invoice with a swapped account number, a request for an urgent transfer supposedly from a client, an attachment carrying ransomware. This is a daily reality you have to be prepared for.

Basic protections:

  • Email filtering that screens out phishing and dangerous attachments before they reach the mailbox.
  • Multifactor sign-in to email and accounting systems, so a stolen password is not enough for a break-in.
  • Verifying changes of account numbers through a channel other than email, for example by phone.
  • Training the team, because people are the last line of defence.

These elements do not cost much, and they can protect the firm from a loss that would hit both you and your clients.

An accounting firm needs IT that understands its rhythm and the weight of responsibility for someone else’s data. Our managed IT services arrange firms’ infrastructure around two pillars: surviving the season and a reliable backup.
