What IT does an accounting firm need?

Four things: the ledger and practice platform, document management that will stand up to an audit years later, email protected against interception, and enough capacity and support to hold through the busy season. The rest is built on those, and the seasonal shape of the work is what makes accounting IT different.

Accounting practices have a workload profile most businesses do not. For much of the year demand is steady; for a few months it is not, and during those months an outage or a slow machine costs disproportionately because the deadlines are external and everyone is already at capacity. Any IT arrangement for a firm should be judged against the busiest fortnight rather than the average week, and that single reframing changes most of the decisions.

The ledger and practice platform sits at the centre, and for most Australian firms that means Xero, MYOB or QuickBooks with a practice management layer around it. The platform choice is the firm's and it is largely settled by how you work and what your clients use. What matters technically is integration: whether documents and correspondence attach to the right client without re-filing, whether workflow and time recording capture where the work happens, and whether staff can reach everything from wherever they are working that week.

Document management deserves more attention than it usually receives, because accounting records outlive the engagement. Working papers, signed declarations, correspondence and lodgement records need to be findable years later, which means storage with genuine structure and permissions rather than a shared drive that grew. In a Microsoft 365 firm that means SharePoint organised by area of work with access lists per area, and retention decided deliberately rather than by default.

Email is the third element and the most attacked. A firm's mailbox contains client financial details, bank information and the instructions that move money, which makes it valuable enough to justify patient effort from an attacker. The realistic scenario is unglamorous: a password is phished, someone reads quietly for weeks, and at exactly the moment amended payment details would be expected, they arrive from a convincing address. Multi-factor authentication on every account and a rule that account changes are verified by telephone to a previously known number defeat almost all of it.

Fourth is the security baseline underneath, and for firms holding client financial data the Essential Eight is the practical framework rather than an abstraction. AFM Services went through exactly this: an on-premise server decommissioned, MYOB migrated to Xero, Zero Trust security deployed with ThreatLocker, and Essential Eight Maturity Level 1 reached. The reason is not compliance for its own sake but that a firm holding hundreds of clients' financial affairs is a concentrated target, and the controls that matter are the ordinary ones done properly.

Remote and flexible work is now assumed in the profession, and it changes where the protections sit rather than whether they exist. When everyone worked in the office the network was a boundary; now the boundary is identity and the device. Multi-factor authentication, managed and encrypted laptops, and access rules that consider where a sign-in comes from do the work the office network used to. Done properly a firm is more secure with staff working from home than it was with everyone in one building and a flat internal network.

The co-managed model is worth knowing about because it suits accounting firms unusually well. Many practices have someone internally capable, a practice manager or a partner who handles the day-to-day, and are not large enough to employ a technical team. Co-managed IT splits the work: internal capability handles the routine, an external provider covers security, infrastructure and escalation. That is the arrangement AFM Services adopted, and it keeps knowledge inside the firm while removing the single-person dependency that makes a holiday stressful.

Two capacity points that only matter at the busy time and matter enormously then. Your internet connection carries everything once platforms are hosted, so it needs headroom and a failover path, because an outage in the last fortnight of October is not a normal outage. And machine age catches up during the peak, since a laptop that feels merely slow in June is genuinely obstructive when someone is working through a backlog, which is an argument for refreshing on a cycle rather than waiting for complaints.

The honest caveats. Not everything needs to change at once, and the sensible order is identity and backups first, then documents, then the platform decisions. Migrations should be timed for the quiet months, and a firm that plans one for September is making a choice it will regret. And technology supports professional judgement rather than replacing it: the review, the sign-off and the client relationship remain human.
