Demonstrate Knowledge of the Clients Business
A successful business proposal must be one that is able to describe, to the client, what their needs and are in a plain and simple but detailed manner. This is very important because your first opportunity to impress a potential client lies in your ability to demonstrate a thorough knowledge of the clients business and challenges.
The main objective of submitting a business proposal is to offer a solution to a problem faced by a prospective client and this part should be as detailed as possible, and should address every issue you have a solution to.
Do Your Research
You've got to remember to be thorough in doing research on your prospective clients as not all clients and buyers will give you detailed information on their wants and needs, particularly for unsolicited proposals. Extend your research to include analysis of competitors of your potential client, and their customers as well. This will ensure that your business proposals will be as comprehensive and detailed as possible.
Another thing to remember is to put yourself in the position of your prospective clients. Doing this will help you provide answers to the questions they would most likely ask, and will enable you explain lucidly, exactly how your solution stands out from those of your competitors.
Once you've gotten all the information you need, you can finally start writing your business proposal. You will need to remember that a proposal is meant to be a convincing document and your writing needs to convey confidence and passion.
Be sure to review your proposal carefully to ensure it completely fulfills the requirements (if any) that where set out. Make sure the information is arranged logically and it fully addresses each of the decision makers concerns. Finally, have someone you trust go through the proposal to be sure it is free of spelling and grammatical errors which could ruin all your good work.
