I'm not selling cakes yet, but I just made a cake for my mother's birthday. Here is the link to the cake: http://cakecentral.com/gallery/2304672/gumpaste-flower-cake
It got to thinking, how do you charge for such an involved cake with flowers. Now, I don't know if it's just because I'm new at flower making but they took FOREVER to make. I would imagine even if your a pro they take a long time due to the steps involved. So do you charge by design, number of flowers, types. I'm really curios how you do this.
You did an amazing job on the flowers - very nice!
The way you charge is more of a personal thing. You can charge by the flower or charge by the hour *that rhymes!* but it's strictly up to you. If you charge by the flower, you need to set a price for each one. If you charge by the hour, you need to set your hourly wage and keep up with the time.
Either way, you're really charging for ingredients + time.
The good news is they do get faster with experience. I know how long it takes me to do most flowers, and I have an hourly rate. So if I can make say 5 roses in an hour, and I get $25 an hour (which includes ingredients, supplies, etc), then it's $5 per rose. It's easier to give the customer a per flower charge for me.
