Thank you for your patience (耐性) and continuous (不斷的) support. I am looking forward to our next business opportunity (合作機會).
I am not sure why you use 包容 in this context. Did you make your business partner mad? If not, then i guess what you mean 包容 here is more like being patient, right? Like you were late on delivering some data or items. So i think the word "patient" would be more appropriate. Unless you really did something so wrong that they eventually forgive you.
