Quick answer: No. You don't have to build a recipe for the proposal, however, building your recipes gives you a great opportunity to expand your portfolio and correctly price your designs.
Often times, florists will opt to send an 'estimate' type contract before creating any recipes. This contract may or may not include inspiration photos, descriptions, and quoted prices. It is by no means exact, but gives the client an idea of what will be created and at what price point.
