I soaped for about 13 months and researched everything for about 6 months before that, before I started my business. I have a full time job with 50+ hour weeks, a soap business and a product photography business.
I do have a ton of room for process optimization in my business. I just started, so only get about one order a week. On one hand, this allows me save some costs and print all the labels, fold the boxes and "build" my package only when I get an order, but on the other hand, it takes me a long time to fulfill an order. I still don't have a good grasp on forecasting order volume and managing inventory based on that, I am guessing all this will come if(and when) the business grows.
