Video in B2B Sales: Explainer Video, Proposal Video, Product Demo

Is video worth it in B2B sales at all?

Video has become cheaper. A smartphone, a clip-on microphone and a quiet room are enough for much of what required a production company ten years ago. Accordingly, owners often hear the advice to work more with video. Rarely does anyone say which video is for what. The result is image films nobody watches to the end and salespeople who go back to email after one attempt.

The guiding question of this article is: In which phase of the sale does which video format bring a benefit, and when is text the better choice? To answer it, I first present a model from communication research that helps in choosing the medium. Then we look at what studies say about buyers and media. After that come the three formats in detail, their effort and their measurement.

A video pays off when it shows something text cannot show. Everything else is just slow text.

The thinking model: how rich does a medium need to be?

In the 1980s, Richard Daft and Robert Lengel developed media richness theory. It ranks communication channels by how much information they can carry at once. The yardstick is four features: how quickly feedback is possible, how many cues are carried, such as voice, facial expression and gesture, whether natural language is used and how personally the message is tailored. The face-to-face conversation is the richest medium, a form the leanest.

The core statement of the theory: a medium fits when its richness matches the task. Ambiguous tasks, where those involved first have to develop a shared understanding, need rich media. Unambiguous tasks, such as an appointment confirmation or a price, are better served by lean media because they are faster and easier to process.

A recorded video takes a middle position. It carries voice, face and movement, but it does not allow an immediate question. That is where its strength comes from: it suits messages in which the person and visual evidence matter but which need no dialogue.

What studies show about buyers and media

There are two common readings of video. The first says: people would rather watch than read, so video works better in every phase. The second says: buyers are under time pressure and want to skim information, so video gets in the way where text is enough. Research proves neither of them entirely right.

Anders, Coleman and Castleberry (2020) surveyed 160 buyers in the United States, including members of the purchasing association Institute for Supply Management. For the first contact with an unknown salesperson, they clearly preferred email. For conflicts, negotiations and getting to know each other, they preferred phone and voicemail, the richer medium. The authors compared three theories of media choice and found that the fit between medium and task explained behavior best.

A finding from an entirely different field supports the same direction. Skinner (2024) studied how companies publish their financial information. Managers tended to choose rich channels such as the conference call with analysts rather than the press release for complex content. When the choice deviated from this fit, the capital market reacted more mutedly to the disclosure.

For the product demo, a survey by Tsimonis (2026) offers a pointer. 478 consumers in the United Kingdom who had shopped via live streams in the previous six months rated, among other things, the quality of the product demonstration, meaning how completely, clearly and vividly the product was shown. A good demonstration went hand in hand with more trust and higher perceived value, and both with higher purchase intention. The author’s explanation: a demonstration reduces the uncertainty about the product that buyers have without seeing it for themselves.

The limits are clear. The buyer survey compares email and phone, not video. The study on product demonstrations concerns consumers and is based on self-reports at one point in time. What transfers is the logic, not the number. My conclusion: video does not replace email in the first contact; it is a tool for the phases in which uncertainty about the person or the service blocks the next step.

The explainer video: answering recurring questions well once

An explainer video answers a question many prospects ask, for example how a project unfolds, what maintenance includes or how a machine is installed. It sits on the website, usually on the service page, and is sent out in sales when the question comes up. It does not replace a conversation, but it ensures the conversation does not start with the basics.

1. Choose the question

   Ask sales which question comes up in almost every first conversation. The video answers exactly one.

2. Start with the viewer’s situation

   The first ten seconds say whom the video is for and which question it answers.

3. Show instead of listing

   Construction site, workshop, screen, process sketch. Where there is nothing to show, text is usually better.

4. Keep it short

   Two to four minutes are enough for almost any question. Split longer content into several videos.

5. End with a next step

   One sentence on what the viewer can do now, the same as on the page.

An explainer video needs a transcript or a short summary next to it. Many buyers watch videos without sound or prefer to skim. Search engines read the text, not the picture. How the service page as a whole should be structured is described in the article A website that generates inquiries.

The proposal video: a face for the proposal

A proposal video is a short, personal video to a specific prospect. In it, the salesperson or owner walks through the proposal, explains the decisions made for the customer and names the next step. It is sent together with the proposal or shortly afterwards.

According to media richness theory, this makes sense because a proposal in B2B is often ambiguous. The prospect has to understand why an item is solved a certain way, and often has to pass it on internally. A video carries the reasoning with voice and face, and the recipient can forward it to colleagues who were not part of the conversation.

• Two to three minutes. Hardly anyone watches longer, and it turns into a lecture.
• Screen and face. The proposal on screen, the sender in a small window.
• Three points. What the customer needs, how the proposal solves it, what happens next.
• No script. Bullet points are enough. A text read aloud seems stiffer than a small slip of the tongue.

How the written proposal itself should be structured and how to follow up is described in the article Proposals that win. The video complements the proposal; it does not replace it.

The product demo: live or recorded?

A product demo shows how a service or product works in use. For software, machines and technical services, it is often the moment a prospect understands what they are buying. The study by Tsimonis (2026) describes the quality of a demonstration in terms of completeness, clarity and vividness. These are useful test questions for any demo.

The two forms complement each other. The recorded demo answers the question of whether it is worth talking further. The live demo clarifies whether the solution fits the specific case. If you regularly give demos to a group, you can also offer them as a webinar. How that works as a source of inquiries is described in the article Webinars and expert talks.

What videos cost and how you measure them

The effort differs greatly by format. The following worked example shows a rough estimate for a small business that records its own videos.

Videos are measured by what happens afterwards. Views say little, because a video can be opened and closed after ten seconds. The following worked example shows the chain for proposal videos.

For explainer videos on the website, the same logic applies as for any page: what matters is whether visitors get in touch afterwards. How to measure inquiries per page is described in the article Measuring the website inquiry rate.

The bigger picture

The question of video is a question of fit between message and medium. Whoever asks it arrives at an order that can be applied to every channel: the unambiguous in writing, the ambiguous in person, and in between video for messages in which a person or visual evidence creates trust but no dialogue is needed.

For the first contact, this means email keeps its role. How a good first email is structured is described in the article The first email to potential customers. Video comes in once the contact has turned into a conversation and the prospect wants to know more than fits into an email. A video from a real customer relationship, such as a narrated case study, combines both: visual evidence and proof.

What remains and how to start

The guiding question was in which phase which video format brings a benefit. The answer follows from the fit between medium and task. In the first contact, email is usually better. The explainer video pays off for recurring questions, the proposal video for ambiguous proposals that are passed on internally, and the product demo for services whose benefit has to be seen. A video that shows nothing text cannot show brings no advantage.

• Agree with sales on the one question that comes up in almost every first conversation.
• Record a two to four-minute explainer video on it with a smartphone.
• Put a transcript or summary below the video on the service page.
• Embed it so that no third-party content loads without consent.
• Send a two to three-minute proposal video with the next ten larger proposals.
• Compare replies and orders with and without video in a simple list.

Video is not a channel but a tool for particular moments in a sale. Whoever knows these moments needs fewer videos than they think.
