The Australian small-firm tech stack, by stage

Stage one: the sole practitioner, roughly to A$250k

What hurts: everything is in one head. The client list is the email inbox, deadlines are memory, and the practitioner is the bottleneck for lodgement, bookkeeping and billing at once. The pressure is time, and the temptation is to buy a big practice system to fix it.

What works: a client ledger (nearly always the one the clients arrive on), a tax and lodgement tool, a bank-feed and receipt tool so the practitioner never keys a transaction, an engagement and payment tool so fixed fees are agreed and collected without chasing, and a document collection tool so client paperwork arrives in one place. That is five tools, all priced per client or per user at a scale a sole practitioner can carry. A practice-management system at this stage is usually a spreadsheet with a licence.

The one thing to do now that pays off later: a standard chart of accounts and a standard month-end for every client. Standardisation is free at ten clients and expensive at a hundred.

Stage two: the first hires, roughly A$250k to A$750k

What hurts: the founder's memory no longer scales. A second person cannot see what is due, what the client was promised, or where the file is. Work in progress is invisible and write-offs appear at year end nobody can explain. Cash is uneven because billing follows the founder's attention.

What works: this is the stage for a real practice-management system, because the job list, the deadlines and the client record have to leave the founder's head. It is also the stage for a document system with a filing convention, and for signing and identity tools so engagement letters and authorities are evidenced rather than emailed. The Australian ecosystem is dense here: several practice systems, each with a stack of tools that connect to it, and the choice of hub decides which tools are easy for the next three years.

The mistake at this stage is buying the practice system for the founder rather than the team. Choose on whether the new hire can run a job end to end from it without asking.

Stage three: the firm with a team, roughly A$750k to A$2m

What hurts: capacity. The firm has enough clients to be busy every week and not enough visibility to say yes or no to the next one. Compliance season is survived rather than planned. Advisory work is sold but delivered inconsistently, because the reporting and forecasting tools are whatever each manager prefers. Client onboarding varies by who does it.

What works: capacity planning in the practice system, used weekly. A reporting and forecasting layer chosen once for the firm, with templates, so an advisory engagement looks the same whoever delivers it. Automation in bookkeeping with firm-level rules, so the margin on fixed fees holds. Payroll as a decided service line, run or referred, not improvised. And a proposal tool wired to the practice system so accepted work creates the job and the billing schedule.

This is also where AI assistants start to earn their place: meeting notes filed to the client record, drafting from the file, coding the exceptions. Judged on the hours recovered per client, not on the demo.

Stage four: the multi-partner firm, roughly A$2m to A$5m

What hurts: the firm now has a practice-level view to build and defend: realisation by partner, write-offs by service line, which clients are unprofitable, which staff are over capacity. The tools that served a team of six creak at twenty. Security and data obligations become a client question, not just a policy. Consolidation and multi-entity clients arrive and the reporting layer has to handle them.

What works: the practice system's own reporting used as the management report, or a data layer that pulls practice and ledger data into the firm's own dashboards. Security, backup and identity tooling that can be shown to a client or an insurer. A consolidation tool for the group clients. A decided position on client data in AI tools, written down. And a rule that every tool must integrate with the practice system as the client record, or it is not bought.

Stage five: A$5m and beyond

At this point the firm is choosing between staying a large practice and becoming something with a different shape: service lines with their own leads, offshore or outsourced capacity, an acquisition or a merger. The stack question becomes an integration and governance question: one client record, one document system, one identity layer, with the specialist tools hanging off them. That is a programme, not a purchase, and it is beyond what a directory can decide for a firm.

What moves a firm between stages

Not revenue, exactly. Three things: the first hire who cannot see what the founder sees; the first season the firm cannot plan; and the first client who asks where their data lives. Each one is a signal that the current stack has run a stage too long. Firms that read the signal early change one system at a time; firms that read it late change three at once in the busy season.

What Australian firms actually run at each stage is the question the directory's Power Lists answer from the stacks firms report, once enough have shared them. Until then, the categories linked from this page are the map, and the cards are the tools.
