Dear (Name of the person),
I am so sorry to tell you that I won’t be able to accept your vendor proposal. I know that it takes a lot to prepare a proposal but it should carry relevant information. The information which is expected from the proposal is not sufficient. You must provide sufficient information that explains how you will fulfill the client’s needs. You should also provide more information like how you can be beneficial to them. The proposal should never be lengthy and needs to get to the point. There are so many flaws that make us reject the proposal. It was a completely vague proposal. I want you to do some adequate research and should learn how the market mechanism works.
I hope that you will not feel demotivated and start working on it. You really need to do hard work for your proposal. It is not necessary that you will always get acceptance for what you did in your life but you should always be ready to learn from your failures. It is something which you really need to learn and I know that one day you will show your success in this.
I completely appreciate your efforts and I hope that you will not let yourself down. If you have any questions regarding the proposal, I am always ready to help you with that please contact ABC at 555555555 or [email protected].
