When a point tool is enough
When a simpler tool is enough, and when it isn't
Buy the right tool, not the biggest one. If your question is how many people pass a spot, or how far someone can drive to it, a footfall dashboard or a drive-time API answers it well, and IRIS would be more than you need.
IRIS earns its place when the money is real and the question is harder: what a specific site will actually earn, how sure you can be, and whether the number holds up where the capital gets committed. That takes a model calibrated to your own estate, tested on stores it never saw, with the range and the drivers attached. It is also why we are honest about our own limits: the range widens in a brand-new market or on a small estate, because that is where the evidence is thin. The point tools leave all of that to you. We don't.
If you are weighing specific alternatives, we have written that comparison down: how IRIS compares, tool by tool, including when to buy one of them instead. And before any vendor call, arm yourself with the five questions to ask a forecasting vendor, us included.
