I am at my wits end. A customer of mine that has ordered cupcakes from me for several years in a row has requested a carved cake to serve 25 people for a birthday. I gave her pricing and sent her some examples of previous work for a similar cake for another customer. She thought the cake looked too small, so I provided dimensions and an explanation of party cake serving size from Wilton. She still felt it wasn't a big enough cake. So I provided her with a cutting chart, showing how it could be cut to get the proper amount of servings. She sent another email back, asking for another quote, for a similar cake, stating she didn't think that the cake I proposed was going to be big enough. I don't know what to do next. I already suggested she talk to another baker and get their thoughts. What would your next move be?

Make her a cake big enough for 50, and charge double your original quote?

"I'm sorry but I don't think I am the baker for you."

is she willing to pay for a larger rendition of this cake? If she is, and you are able to, just make her the larger cake. She may just have a ton of leftovers, and an unheard "I told you so" looming over her head!!

I don't get what the problem is...if the customer wants to pay for a bigger cake, give them a bigger cake. Wilton's serving size of 1.5"x2" is just a suggestion, and if the customer wants to have bigger servings that is their prerogative.

give the customer however much cake she wants, just be sure you charge appropriately for it.

although, she will have a bunch of cake leftover.

I had a 50th birthday party cake order and they thought the wilton serving size was just too small so they ordered and paid for double the amount of cake so they could serve generous slices. Against my recommendation, but they were paying so I didn't complain when I cashed their check.

They actually had the nerve to complain that I wasn't at the party to deal with all the extra cake that was leftover. SERIOUSLY, I left some boxes for the leftovers, but they had a ton of cake left because the caterer didn't know she should cut the slices huge and cut them normal size.

So what's the problem? Once she stated she didn't think it was big enough you quote the next size (or 2) up from there. NO need to go all through what you did.
She wants a bigger cake - give her the next size (or two) up and be sure to charge for whichever size she picks.

I definitely wouldn't refer her to another baker...it sounds like she wants to purchase a larger cake.

She obviously feels that the "suggested serving size" isn't large enough...don't send her away, quote her the larger size.

If she wants more cake, give her more cake...with the higher price At least if she has a ton of cake left over you can tell her that you told her so!
