Yeah, I have thought about this. These three original memberships I was talking about were the basic ones. I do have in place like advanced ones for each category. Each upgrade comes with more features, like analytics for your shop or the ability to create profiles (and configure their capabilities) within your shop and assign them to employees - so there could be normal employees, managers etc. Each one of these upgrades comes with a bigger product limit too. The problem is that I don't really have a concept of how many products does your average online shop sell on a regular basis, so the numbers I have on them right now are pretty much random. I don't know if a 100 is a lot or not, you know? I need to do some research about this and think about a strategy. I can easily charge sellers per product. Or just per product if above certain limit. Or I could charge them a fixed price per month in exchange of X limits (or unlimited). Etc. I do have the flexibility to pretty much whatever I want. What I don't have are easily available references to see and decide what to do.
