Business decision – reply to an offer


I’m a ceramic artist, and working almost full time as a designer on the side.

Some gallery or store asked me to get some pieces. All my work is handmade and unique pieces, meaning it takes time to make it, and I do not reproduce it.

I struggle to manage my production as I’m working full time on the side and it’s a challenge being able to produce more.

I have to reply to one store who just told me they would be interested in having some pieces and I wonder:

What should I reply to this store if I don’t have any pieces left or anything to offer?

I feel guilty to say I have no pieces to offer.  It feels unprofessional and I feel I’m not able to grow my business.

Let me know if you have any advice,

Thank you.
