Writing a professional proposal needn't be difficult if you keep several important considerations in mind. First, resist the urge to write to impress such as by using fancy language or technical jargon. Instead, use plain language that clearly explains what your readers want and need to know about your proposal. Second, remember to check the details, such as making sure there are no typos or errors of any kind in your proposal. Third, keep in mind that your objective in writing a professional proposal is to persuade your readers to give you work, so make sure you follow their directions in their Request for Proposal (RFP) and convince them that you and your company will provide exactly what they need.
