A business proposal contains a number of elements, including an introduction, marketing data and forecasts, and conclusion. While the other elements are important, a well-written conclusion serves to pull the entire proposal together and can be the defining element that closes a deal. The conclusion should address any potential concerns investors may have, as well as summarise the entire proposal in a few paragraphs. The tone of the conclusion should be positive as well as realistic to convince investors that the proposal is worth accepting.
Make a list of key points in your proposal. The conclusion should always be the last thing you write and should focus on the key elements you included in the document. Put yourself in your investor's shoes. Include points that will be of interest to him such as marketing plans, proven success in the past, and a clear path to future success.
Write a list of potential questions investors may have after reading your proposal. You may want to enlist the help of others, asking them to read through your proposal and tell you the questions they have. Often, the author of a business proposal is too close to the information and may miss something that outsiders will catch.
Begin the first draft of your conclusion. Ideally, the conclusion should be no more than one page in length or approximately 350 to 500 words. Include a logical progression that summarises your plan as well as your vision for the future. As mentioned previously, the tone should be positive but also realistic. Avoid making promises or statements that can't be backed up.
Edit your first draft. Remove anything that's not relevant to the proposal. It's important that you don't work too hard at convincing investors that your plan is worth their time and money. Rather, let the plan speak for itself. A well written and solid business plan will outperform a plan that tries too hard and can't back up its projections.
Finalise the conclusion. Make any necessary changes, reread it one more time and add it to your business proposal. Again, you may want to have a friend or colleague read it to ensure you catch any inconsistencies or problems.
