Quick answer: A proposal deck is a client-facing presentation of a proposed engagement: the understanding of the problem, the scope, the timeline, the deliverables, and the price. The deck is the basis for the signed agreement, so it is precise.

The structure

  1. The cover. The client, the project, and the date.
  2. The understanding. The problem as the client described it.
  3. The goals. The outcomes the engagement delivers.
  4. The scope. What is included, in specific terms.
  5. The out-of-scope. What is explicitly not included.
  6. The approach and timeline. The phases and the milestones.
  7. The deliverables. The specific artifacts handed over.
  8. The team and the process. Who does what, and the working method.
  9. The pricing and the terms. The price, the payment schedule, and the assumptions.
  10. The next step. The sign-off and the start date.

The out-of-scope slide

The out-of-scope slide is the most valuable slide in the deck. It lists the things the client might assume are included but are not, and it prevents the scope disputes later.

The deliverables are concrete

  • The named artifacts (the deck, the site, the assets).
  • The number and the format.
  • The delivery milestone.
  • The acceptance criteria.

Vague deliverables ("design support") are the source of later arguments.

The timeline

The timeline is in phases, with the milestone and the deliverable attached. Dependencies are stated where the client must provide something.

The pricing and terms

  • The price and the payment schedule.
  • The assumptions (the access, the data, the client's review time).
  • The change process: what happens when the scope changes.

The relationship to the contract

The proposal deck is the visual version of the agreement; the contract is the legal version. The two must agree on scope and price. The deck cannot replace the contract, but it can prevent the misreading the contract later has to resolve.

Length

10–15 slides; the proposal is a specific document and should not become a company overview.

Frequently asked questions

Is the proposal deck the same as the statement of work? The SOW is the signed document; the proposal is the presentation that precedes it. Should the price be in the deck? Yes; the commercial terms are part of the proposal. Can the out-of-scope slide be omitted? It shouldn't be; it is the slide that prevents the most disputes. What format is sent? The PDF is sent; the editable PPTX allows revisions during the negotiation.

Write the out-of-scope slide carefully; it is the slide the project will be judged by.
