Just want to know how much I can charge a lady that wants an order of 126 cupcakes?
Do you have a standard rate for cupcakes?
Your cupcake price will depend on the area you live in. I've seen anywhere from $3-$6 ea. in my area for BC only & fondant of course is extra. In your price you should also consider the overhead & find out if you are providing a stand or the customer is. Also packaging will play a factor as well. Once you determine the price for ea then just multiply it by the amount she wants.
I would figure it the same way I would figure a cake, but instead of breaking it down to a per serving price you'd do a per cupcake price.
