Signs of eventual burnout too, might I add. It's soooooo rewarding when you put all the pieces in place before you go public. Pricing structure, replying to clients, general organization skills, etc., etc. All of which you can get ideas for from here. But *then* start selling. Less surprises that way, less headaches, etc. Makes life easier.
Absolutely 100% right. You'll be much less likely to run into situations that you can't handle if you've thought things through ahead of time and don't just wing it. It would be easier to just not offer special order types of cakes if you don't have those worked out, and it isn't fair to customers or to yourself to add the stress of "figuring it out as I go and maybe it will work" to what should be a simple order.
