I have a question regarding cupcake business. A friend of mine have yogurt shop and she wanted to sell cupcakes in her yogurt shop. She wanted me to make it for her.

My question is
Do I have to provide the packaging of the cupcakes for her(boxes, cupcake liners and etc.)?

How many flavors of cupcake should we display?
How many cupcakes in each flavor should we display everyday?
Do you sell your 1 day old cupcakes for a cheaper price or throw them out?

Our arrangement is she will buy the cupcakes from me and she will sell it at her yogurt shop. We haven't discuss all the details yet because she is on vacation right now.

I am renting a commercial kitchen to make this cupcakes because she don't have a kitchen for baking in her yogurt shop and I am paying $20/hr for the commercial kitchen.

Please advice. Thank you
