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 — general legal research, first-pass summarisation, 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 — 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.
