I love selling stuff from our store, but up until today there has been a price for success. Namely, I've had to check quantities on items we're selling against what we have in stock. When it gets close to zero I pull that item from the site. Sometimes I miss it and we accidentally sell stuff we don't have. Or I do it too soon and we get stuck with one or two of this and three of that, with no easy way to get rid of them except in a clearance box at a conference. When we're busy I have to do this several times a day. It's a pain.
But I just put in a surprisingly sophisticated inventory system that (finally) does this sort of thing automatically. Now for the most part we'll just sell stuff until it's gone with no plans to reorder. And that means I can get back to work.
