Why ThatDeal's calculators are different

Most Australian business valuation tools ask two questions and return a single number. That's not how acquisitions work. The price a buyer pays and the value a seller expects are shaped by industry multiples, owner dependency, debt serviceability, state-based stamp duty, and a dozen other factors that generic tools ignore.

ThatDeal's calculator suite was built for the $500K–$5M SMB market — the segment where most first-time acquirers and time-poor professionals are shopping. Each tool explains the methodology, shows Australian industry benchmarks, and flags when a deal looks structurally tight.

After running the numbers, ThatDeal can provide full intelligence reports on specific listings — including Done-for-You broker calls, red/yellow/green flag analysis, and comparable sales data.
