Almost every Australian business has one. A spreadsheet that started as a quick way to track something and is now, without anyone deciding it, the system the business depends on. The roster. The stock file. The job costing model. The quoting calculator with the pricing rules built into it. The compliance register that tells you whose induction expires next month.
The decision to replace spreadsheets with custom software in Australia is usually made too late — after a version conflict costs a day of work, or after a formula has been quietly wrong for a quarter. It is a better decision to make deliberately, while the spreadsheet still works.
Be clear about the other half of this. Plenty of spreadsheets should stay spreadsheets — a spreadsheet is the fastest modelling tool most businesses have. If one person uses a file to think, to model a scenario or test a price change, leave it alone. Building software around exploratory work makes it slower and worse. The same goes for anything used a handful of times a year, or where the point is that you can restructure it on the spot. The spreadsheets worth replacing are the ones several people depend on, that run on a schedule, and that other work is queued behind.
We are Drawn AI, an Australian business started in 2024 by Liam and Jacob — one from retail operations management, one from mining operations. Both of us have been the person maintaining the file everyone else relies on. We build replacements that connect to what you already run: Xero, MYOB, Shopify, Cin7, Deputy, SimPRO, Employment Hero, SQL Server.
