How to prepare a business proposal a buyer can approve

A good meeting ends with a request for a proposal. You prepare a solution description, a pricing table and a company introduction. Your contact thanks you, forwards the document to a manager, and the conversation stalls.

The proposal may contain every product the buyer requested and still leave out information needed to make a decision. The manager was not in the meeting. They do not know which problem you discussed, why you chose this scope, or what would happen if the purchase were postponed. Your contact has to explain everything again.

When preparing a B2B business proposal, start with this question: can the recipient use it to justify the purchase internally without extra commentary from the seller? The method below helps you collect and present the information they need.

1. Establish the buying decision before writing

“We need a new system” or “send us a price” does not explain how the buyer will evaluate your offer. Before preparing a tailored proposal, record five answers:

1. What happens today? Ask for a specific recent example. Where did the process break down, who had to fix it, and what was the consequence?
2. What needs to change? Agree on an observable improvement, such as shorter preparation time, fewer corrections or clearer pricing.
3. What determines the choice? Which criteria are mandatory and which are negotiable? What takes priority if budget, scope and timing conflict?
4. Who takes part in the decision? Who will use the solution, manage implementation and approve the investment? What does each person need to know?
5. What could stop the purchase? Missing data, unclear ownership, a competing project, budget approval or a specific technical condition?

Not every purchase needs extensive discovery. A repeat order for clearly defined products may only require confirmation of what has changed. In a complex sale, however, a better-looking document will not resolve missing answers. If a material condition is still unknown, identify the assumption and who needs to confirm it.

2. Put the recommendation and its reasoning first

Your company history can come later. Start with the buyer's situation, your recommendation and its boundaries.

An opening in a packing equipment supplier's proposal might read:

Your warehouse currently packs parcels of different sizes by hand at one workstation. We recommend first testing the proposed packing machine with your own packaging. The offer includes the machine, agreed accessories, delivery, commissioning and operator training. We will confirm the final configuration and suitability after the trial.

This is an illustrative equipment supply example, not a real customer story. Adapt it to verified operating conditions and the actual discussion. It makes the recommendation explicit instead of leaving the reader to infer it from technical specifications.

If you cannot explain why you chose the configuration, return to the needs discussion.

3. Support the value with a calculation the buyer can inspect

“You will pack faster” is open to interpretation. Show the inputs and assumptions behind the estimate. Distinguish what the buyer has confirmed, what you are estimating and what remains unknown.

Hypothetical packing equipment example. All figures are illustrative, not customer results or a machine performance promise. Suppose a warehouse packs 360 parcels a day and operates 20 days a month. A defined manual packing task currently takes an average of 45 seconds per parcel. The assumption being considered is that the same task could take 30 seconds after the change. That duration still needs testing with representative samples of the buyer's packaging.

The €540 is not an automatic reduction in company spending. It is an estimate of potentially released working time under the stated assumptions. Establish how the time would be used and whether packing is actually the constraint in the process. If another workstation limits dispatch, shortening a packing task will not automatically increase overall warehouse throughput.

Include the cost of the machine, accessories, delivery, commissioning, training, consumables and maintenance in the assessment. Seconds saved alone do not establish payback. If parcels differ, compare the same tasks, packaging and quality requirements in the trial. Do not add sales growth to the calculation without evidence to support it.

Here is how the value argument itself changes:

Before: “This machine will increase your warehouse throughput and pay for itself quickly.”

After: “At a volume of 7,200 parcels a month, reducing the same packing task from 45 to 30 seconds would release 30 working hours. This is an assumption to test. We propose checking time and packing quality with your packaging samples, then assessing the benefit alongside all operating costs.”

The second version makes the source of the benefit and the remaining uncertainty visible. Agree on the trial procedure and assessment criteria with the buyer too.

4. Connect the price to scope and responsibility

A single total can leave the buyer unsure what they are purchasing. A long list of small line items can hide the choices that matter. Provide enough detail to explain the price and allow a fair comparison with alternatives.

For each material phase, specify:

• what you will deliver and how completion will be assessed;
• what the buyer must provide and by when;
• what the price excludes;
• which changes would require a different price or timeline.

For example, “delivery and commissioning” might cover transporting and setting up the machine, or it might also include moving it into position, preparing the workstation and operator training. If the price includes only some of that work, make the boundary visible before approval.

One equipment quote may cover only the machine, while another includes required accessories, delivery and commissioning. Show which items are necessary, who supplies them and which scope the buyer is actually comparing.

Separate one-time and recurring costs. Distinguish optional items from required work. The buyer should not have to guess whether another mandatory project phase will follow the first payment.

5. Build alternatives around real trade-offs

Three packages are useful when they help someone choose. They offer little help when only the names differ or the middle option has been made artificially attractive.

You might compare these approaches:

Do not offer a phased approach if it does not work technically or economically. Avoid artificial urgency: explain the consequences of waiting only when you can support them with the buyer's circumstances.

Recommend one alternative clearly. Explain which buyer priority supports your recommendation and what would make you change it.

Sometimes the cheaper alternative is the better recommendation. If parcel volume is low, packaging varies widely and packing is not the constraint, manual tools may fit better than automation. Do not manufacture an equipment payback case. Explain what would make reassessment useful, such as an increase in recurring parcels using the same packaging type.

6. Write for people who were not in the meeting

One proposal may pass through several hands. You do not necessarily need separate documents, but the main answers should be easy to find.

A manager needs to understand why the project is worth undertaking and which risks the company will accept. A daily user wants to know how work will change and what help will be available at the start. Finance needs the full cost and payment terms. If systems or data are involved, a technical reviewer needs verified requirements, dependencies and unresolved questions.

Keep a short decision summary at the beginning and place technical detail in a separate section. Do not present unconfirmed integrations, security arrangements or delivery dates as agreed facts.

7. End with an action that moves the decision forward

“We look forward to hearing from you” does not tell the buyer what response is needed. Close with the next decision and what is required to make it.

For example:

Next step: agree on the scope of a trial using your packaging samples with the warehouse manager. We need to select representative parcels, agree on time and quality assessment criteria, and confirm workstation preparation requirements. After the trial, we can agree on the final configuration and delivery terms.

Ideally, agree on this step before sending the proposal. If you need to follow up later, return to a specific unresolved question. Opening or reading a proposal does not, by itself, establish an intention to buy.

How to prepare proposals faster

Build speed before the next sales conversation. Maintain approved solution descriptions, clear pricing rules, scope boundaries for recurring work and questions to resolve with the buyer. Assign ownership of those materials and decide when they need updating.

Reconsider the buyer's situation, recommendation, value case and uncertainties for each opportunity. At the same time, you should not need to rewrite verified technical information or manually rebuild the same catalogue for every proposal.

Wantly can support that workflow through proposal templates, content blocks, a product catalogue and pricing rules. These help teams reuse prepared information. The team still needs to establish the right scope, realistic assumptions and a reasoned recommendation for the buyer.

Before sending, ask a colleague who missed the meeting to explain what you recommend, why, at what price and what the buyer must decide next. Wherever your colleague has to guess, the buyer is likely to have the same difficulty.
