Unlike estimates, quotes, and bids, proposals include information beyond the specific cost of a project or service. Proposals provide an in-depth explanation of the work being done, with details about scope, deliverables, milestones, and qualifications as well as budget.
While a business plan and business proposal might sound like the same document, one focuses on a company’s internal operations while the other seeks to create a business relationship with another company. A business plan, usually written with the intent of securing funds from an investor, summarizes a company’s overall goals and objectives. On the other hand, a business proposal focuses on a specific project or service for a prospective client.
