how much should I charge for a full clay on a car using a clay towel as well as a one step correction on a 2015 Honda Accord

Hey guys I’m doing interior details right now but looking into doing exterior details soon does anyone have any advice on what products to use?

What do you guys do for upsells? I need to get better at that. Luckily, most people give me a tip, but still. When do you present the upsell, at the start? Give me some tips!

I’m focused on scaling my detailing business as much as possible right now, but I’ve been thinking ahead about the seasonal slowdown—especially winter (I know we are past that but still, I’m in Michigan the winter is pretty bad here) My goal is to build systems that keep work coming in year-round, not rely on fallback options when things get slow. What should I be doing right now to prepare for that? Or should I ignore that for now and stay fully focused on scaling?
