When writing proposals, it’s not all about what you say; how you say it is critical to conveying the right message to your audience. One of the key issues that makes a proposal stand out for the right reasons is voicing. You shouldn't be dogmatic about every single sentence in a proposal, but, for the most part, proposals should be written in Active Voice. Need a refresher?
Passive Voice: The prototype was built to specifications.
ACTIVE Voice: We designed and fabricated a prototype that meets or exceeds all specifications.
Where passive voice often makes writing sound weak or wishy-washy, Active Voice tells what YOU DID, not just what was done. It’s a more powerful way to convey the message you need to convey in proposal, and it lends an air of confidence an authority to your writing, which will make your proposal that much more credible to an evaluator.
