Every Australian firm evaluating AI eventually hits the same fork in the road: buy a product off the shelf, or build something around how the firm actually works. Both can be right. The mistake is treating it as a single decision rather than a portfolio one.
Where buying wins
For broad, horizontal tasks like general legal research, first-pass summarisation, and everyday drafting, established products are hard to beat. Tools like Lexis+ AI, CoCounsel and the AI built into practice management systems are mature, supported, and improving constantly. If a task looks the same at your firm as it does at every other firm, buying is usually the faster, cheaper path.
The trade-off is differentiation. If your competitors can buy the same tool tomorrow, it makes you faster, but it does not make you distinctive.
Where building wins
Building makes sense when the work is specific to your practice, your jurisdiction, or your firm’s way of doing things. A tool that understands the Corporations Act and ASX workflows, or that assembles Form 13 financial statements for family law, is not something you can buy in a generic box. That specificity is exactly where the time savings, and the competitive edge, live.
Building also changes the ownership equation. When you build, the workflow, the data and the IP are yours. There’s no per-seat licence escalating each year and no vendor deciding your roadmap.
A practical test
Ask three questions of any candidate task:
- Is it generic or specific? Generic leans buy; practice-specific leans build.
- Is it core to how we win work? Core capability leans build; commodity leans buy.
- What’s the cost of the data leaving our control? High-sensitivity work leans build, in an environment you control.
Most firms land on a blend: buy the commodity layer, build the few things that make the firm distinctive. The firms pulling ahead aren’t the ones that “adopted AI.” They’re the ones that built AI around the tasks eating their lawyers’ days.
If you’re weighing that decision, book a call and we’ll help you map which of your workflows are worth building.
