How to Explain Complex Software Clearly to Any Audience

A billing workflow can put a customer’s plan, payment status, permissions, and an outside payment provider behind one “Pay” button. The user sees one action; the system’s connected parts can produce different results. That gap is why teams need a practical way to learn how to explain complex software to customers, executives, and new users without giving them an architecture lecture.

To explain complex software, start with the audience’s task, then describe the product promise, the steps the user takes, and the outcome they can see. Use a real workflow or screen as evidence, and include technical detail only when it changes a decision, action, or expectation. This makes the product understandable without pretending its underlying system is simple.

The approach below gives you a repeatable structure for product pages, presentations, and videos, plus checks to find the point where listeners lose the thread.

What People Mean When They Call Software Complex

People call software complex when understanding what it does requires keeping track of many connected parts—not simply because it has a long feature list. A user action may pass through an interface, application logic, data storage, and an external service. Each part has its own job, but its connections and dependencies shape what happens next. Change one part, and the behavior of another may change too.

Complexity also involves behavior that is hard to predict from any single component. For example, a billing workflow might depend on a customer’s plan, payment status, permissions, and an outside payment provider. Those conditions can combine to produce different results, even though the user sees one “Pay” button. Research on complex software systems describes this in terms of interacting components, dependencies, and behavior that can emerge from those interactions.[^1]

That does not mean every complex product is poorly designed. A system can have many parts and still have a coherent structure; the difficulty may be that a new user has not yet learned how the pieces fit together. Conversely, a small application can feel confusing if its behavior is inconsistent or its relationships are hidden. The practical measure is what someone must understand to complete a task or make a decision—not the number of screens or lines of code.

This distinction matters when deciding how to explain complex software. Simplifying the underlying code means changing the system itself: perhaps reducing dependencies or improving how components are separated. Explaining the product is a different job. We make the system’s purpose and visible behavior understandable without claiming that its internals have become simpler. A useful explanation gives someone enough context to see what the product does and why the parts they encounter matter; it does not need to teach them the entire architecture.

That is the communication challenge behind saas explainer videos: translating a system with many interacting pieces into an account a customer can follow. The distinction keeps an explanation honest. We are not pretending the system has no dependencies or edge cases; we are choosing a useful level of description for the person trying to understand it.

Start with the audience, not the architecture

Before explaining a product, decide who needs the explanation and what they need from it. A new user trying to complete a task, a buyer comparing options, and an executive deciding whether to fund a rollout may all ask about the same software—but they need different answers. Google’s technical-writing guidance recommends identifying both the audience’s role and how familiar they are with the subject; job title alone does not tell you what someone knows.

Use three questions to set the scope:

1. What does this person already know? Identify relevant experience, not assumed intelligence. A product manager may understand APIs but not know your system’s terminology. A new customer may know the problem well but have never used software like yours. If you are unsure, ask what they have used before or what terms they already recognize.
2. What do they need to decide or do? Name the decision or task in one sentence: “Choose whether to connect the CRM now,” or “Send an invoice for approval.” This becomes the test for whether a detail belongs in the explanation.
3. What could they misunderstand in a consequential way? Keep details that change the decision, the next action, or the limits of what the product can do. Leave out details that serve only to show how much the team knows.

For example, a new customer evaluating a scheduling tool may need to know whether it can prevent two people from booking the same slot. They probably do not need the names of the services that check availability behind the scenes. An administrator configuring that tool may need to understand which calendar is authoritative, because that detail affects setup and prevents conflicting bookings. The right level of explanation changes with the task—not with a blanket rule to avoid technical language.

Write a one-line audience brief before drafting: “This is for [person] who already knows [context] and needs to [decision or task].” Then make a short keep-or-cut list. Keep a technical point if omitting it could lead to a wrong choice or action; otherwise, save it for a deeper explanation or supporting material. This audience-first approach applies whether you are writing documentation, presenting a demo, or planning saas explainer videos. For customer education, the customer onboarding video guide can help you think through what new users need at each stage.

Turn features and technical language into user outcomes

A feature name tells people what your team built; it does not automatically tell them why it matters. Translate each feature through four links: component → problem → user action → visible outcome. This keeps the explanation tied to something the audience needs to do, rather than asking them to understand an internal label first.

Use this repeatable prompt for each feature you plan to explain:

1. Component: What capability or system part are we describing?
2. Problem: What gets in the user’s way without it?
3. Action: What can the user now do?
4. Outcome: What changes that they can see, decide, or accomplish?

Then write the explanation in plain language: “When [problem] happens, use [capability] to [action], so you can [outcome].” If the final clause is vague—“improves efficiency,” for example—name the observable difference instead. The point is not to remove technical terms at all costs; it is to connect each one to a consequence the listener can recognize.

For example, a SaaS team might describe a feature as “event-driven notifications.” That label leaves the audience to infer the value. A more useful translation is: “When a payment fails, the system flags the account for the billing team, so they can follow up before the customer’s access is interrupted.” The technical mechanism may still matter to an engineering audience, but a customer can understand the trigger, action, and outcome without learning the implementation first.

Apply the same test to system components. “We use a queue” is an implementation detail; “large imports can run in the background, so you can keep working while they finish” connects the component to a user benefit. Keep the internal term if it helps a technical buyer assess fit, but pair it with its practical effect rather than leaving it to stand alone.

For a product video, match the words to evidence on screen: show the import starting, the user returning to another task, and the completed result. Velos, for instance, can turn a website or product-page link into a video featuring real product screens; its homepage describes close-ups of the actual interface, including a button or chart a scene is about. That gives you a way to connect a capability to a visible action rather than listing features in isolation. Use this translation for each scene: name the user’s problem, show the relevant action, and state what changes as a result.

Use a simple structure to explain a complex product

A useful explanation moves in a straight line: problem → promise → workflow → evidence → next step. Give each part one job, so the listener can follow how the product connects to a real need instead of having to assemble the story from a list of features. This structure works for a presentation, product page, or one of your saas explainer videos.

1. Name the audience’s problem. Describe a situation they recognize, not a broad category such as “inefficient work.” For example: a support lead needs to spot recurring complaints but has to review conversations one at a time.
2. State the product promise. Say what changes for that person. Keep it specific enough to connect to the problem: “Find common issues across customer conversations without reading every conversation manually.”
3. Show the key workflow. Choose the shortest sequence that makes the promise understandable. Explain what the user provides, what the product does, and what the user sees or does next.
4. Give important evidence. Demonstrate the workflow or point to a relevant, supportable result. A screen showing an issue grouped from several conversations can substantiate how the product works; an outcome statistic should only appear if you can verify it.
5. Offer one next step. Match the invitation to the explanation, such as trying the workflow, viewing a product demo, or learning more about a specific capability.

Here’s the structure applied to a fictional customer-support analytics product:

• Problem: Support leads hear similar complaints but cannot quickly tell which ones are recurring.
• Promise: The product helps them identify repeated issues across conversations.
• Workflow: Connect the conversation data, review the grouped themes, then open an example conversation to understand a theme.
• Evidence: Show a theme alongside the real conversations grouped under it. This demonstrates the product’s behavior without claiming it saves a specific amount of time.
• Next step: Invite the viewer to explore a sample analysis or see a demo.

The example stays coherent because the evidence returns to the opening problem: repeated complaints were difficult to spot, and now the viewer can see them grouped. If the product cannot show a verified customer result, a real, representative product action can still support a narrower claim about what it does. In a short video, you can give each beat a distinct moment; in a longer explanation, expand the workflow or evidence without adding unrelated benefits. The structure is a useful starting point for planning a SaaS explainer video.

Make the explanation visual with workflows and examples

Choose a visual that answers the viewer’s next question. A diagram can show how parts connect; a product walkthrough can show what someone does; a real screen can prove what the software actually looks like. An analogy can give a quick mental model, but it should clarify the workflow—not stand in for evidence when the viewer needs to see the product.

A practical way to choose is to start with the point you need to make:

• Use a workflow diagram when the explanation depends on sequence or handoffs, such as how a request moves from submission to approval. Show only the stages and connections needed to follow that path.
• Use a product walkthrough when the viewer needs to understand how to complete a task. Show the starting state, a few meaningful actions, and the resulting state.
• Use a real screen when trust or usability depends on seeing the actual interface—especially a distinctive dashboard, report, or setting. Crop or zoom to the relevant area rather than leaving the viewer to search the whole screen.
• Use an analogy when a familiar comparison makes an unfamiliar concept easier to picture. Follow it with the actual product behavior so the comparison doesn’t create a misleading impression.

For example, to explain a project-management product’s automated task handoff, don’t tour every menu. Show one task moving from “ready” to “in progress,” identify the condition that triggers the assignment, then show who receives it and where the team sees the update. A small diagram can establish the handoff; real product screens can show the trigger and result. The viewer sees one cause-and-effect path instead of a list of features.

Keep that path consistent across formats. In a live presentation, point to each relevant area as the workflow advances. In a video, sequence the same screens and use brief labels or narration to explain what changed. This is also a useful approach when planning saas explainer videos: make each visual earn its place by advancing the same explanation.

If the key screen is behind a login, use an accurate capture or screenshot rather than substituting a generic mockup. Velos supports showing screens behind a login through sign-in or uploaded screenshots, and can turn a website or product-page link into a video with real product screens. See our guide to recording a software demo for more on preparing a clear screen-based walkthrough.

Decide how much technical detail to include

Technical detail earns its place when it helps someone understand a decision, a risk, or an outcome. If a component name does none of those things for the audience, leave it out of the main explanation and keep it in supporting documentation. That lets us explain a complex product without implying that its underlying code has been simplified.

Use this test for each internal detail: does the listener need to know it to understand what happens, why it matters, or what they should do? If not, translate it into a plain-language consequence. For example, a dependency is another piece of software your product relies on. A customer may not need its name; they may need to know that an outage in that service could delay a report or interrupt sign-in.

Architecture matters when it changes what users can expect. Microsoft’s Azure architecture guidance describes microservices as having challenges such as managing communication across services and preventing failures from cascading. In a customer explanation, that could become: “The reporting and billing parts work separately, so a problem in one is less likely to stop the other.” Use that statement only if it accurately describes your product; the architecture label alone does not prove the benefit.

Open-source components also need context, not a list of package names. If a component affects a buyer’s decision—for example, because they need to assess licensing, security review, or support—explain what the component does and what responsibility your team retains. If it has no bearing on the listener’s task or decision, it is usually implementation detail rather than explanation.

A useful way to keep the levels distinct is to describe the same system in three layers:

• User layer: “You can see which invoices are overdue.”
• Workflow layer: “The app imports invoice data, matches payments, and flags unpaid items.”
• Architecture layer: “Separate services handle imports, payment matching, and alerts.”

Start at the user layer and move deeper only when the conversation calls for it. The architecture layer may help a technical buyer understand system boundaries or a team member diagnose a failure; it can overwhelm someone who only needs to complete a task. This is the same editorial choice we make in saas explainer videos: include internals when they clarify the product’s behavior, not simply because they exist.

Common mistakes that make software harder to understand

A clear explanation can still lose people through small choices in wording and structure. Watch for these four mistakes when preparing a product page, presentation, or video.

1. Using jargon as shorthand. Terms like “event-driven architecture” or “idempotent processing” may be precise for engineers, but they make other listeners stop to decode the sentence. Replace the term with its practical meaning: instead of “event-driven,” say “the system updates the team when a customer’s status changes.” If the technical term matters to the audience, introduce it after the plain-language explanation and define it once.

1. Listing features without a reason to care. A run of capabilities—dashboards, permissions, alerts, integrations—leaves the listener to figure out which one matters. Group features around a task or pain point, then explain what changes for the user. For example, connect role-based permissions to a concrete job: “Managers can approve access without giving every teammate the same controls.” Keep a longer capability list for a reference page; a spoken explanation or short video needs a clear route through the product. Our guide to choosing a SaaS explainer format can help match the format to that job.

1. Introducing abstractions without an anchor. Words such as “orchestration layer,” “workspace,” or “single source of truth” can sound meaningful while leaving people unsure what they would actually see or do. Pair the abstraction with one recognizable example: “The workspace is where support agents see a customer’s open requests and recent activity.” Avoid stacking several abstract terms in one sentence; explain one concept, then connect it to a visible screen or action.

1. Describing implementation but not its significance. “We use microservices and open-source components” tells a listener something about construction, not what the product helps them accomplish. Keep an implementation detail only when it answers a relevant question—such as how the product connects to existing systems or handles a required workflow—and state that consequence plainly. Otherwise, move the detail to technical documentation rather than asking every audience to interpret it.

A useful editing pass is to underline each acronym, feature list, abstract noun, and implementation claim. For each, ask whether it helps the intended reader understand what they can do or why it matters. If not, translate it, add a concrete example, or cut it. This makes saas explainer videos easier to follow without watering down the product.

Test whether your explanation is working

A listener saying “yes” when you ask whether they understand is not a useful test. Ask them to explain or use the information instead. Their answers show whether your explanation made the product’s purpose, workflow, and next step clear—or where you need to revise it.

Try these three checks with someone who is not already familiar with the product:

1. Purpose: “In your own words, what does this product help someone do?” Listen for the intended user and the main job the product performs. If they describe a different problem or audience, clarify the opening claim.
2. Workflow: “What would you do first, and what happens next?” They should be able to describe the main path through the product without listing every feature. If they skip or misorder a step, revisit the part of the explanation that connects those actions.
3. Next step: “What would you do after this?” The answer might be trying a workflow, asking for a demo, or taking another action your explanation invites. If the listener cannot identify one, make the call to action more explicit.

Frame the questions as a check on your communication: “I want to make sure I explained this clearly—how would you describe what happens next?” That makes it easier for someone to point out confusion. Avoid relying on “Does that make sense?” because a quick yes does not tell you what they understood. A restatement in the listener’s own words gives you more to work with.

When an answer is off, revise the section that caused the misunderstanding rather than adding more explanation everywhere. If the listener gets the audience but not the product’s job, sharpen the purpose statement. If they understand the promise but lose the workflow, make the sequence easier to follow. If they can explain the product but do not know what to do, clarify the next step. Then ask the same check again.

For a video or presentation about a product, use the same checks after a first viewing: can someone say what the product does, describe its central path, and name the action they should take? These questions can help teams judge whether their saas explainer videos communicate the product—not just whether the screens look polished. Treat each answer as a clue about what to revise, not as a score for the listener.

Choose the explanation by the job it needs to do

Use the listener’s task and decision as your threshold for choosing what to show. A single core task usually calls for a focused walkthrough; a decision that depends on how parts connect may need a simple diagram as well.

• If someone needs to complete one task: Show the starting state, the key actions, and the result on a real product screen. Keep the explanation centered on that path rather than touring every feature.
• If the decision depends on sequence or handoffs: Add a workflow diagram that shows only the relevant stages and connections, then use the product screen to make the behavior concrete.
• If the audience includes people with different decisions to make: Create a version for each audience’s task. Give a new user the steps they need, and reserve architecture or dependency detail for people assessing those issues.
• If a technical detail affects a choice, risk, or expectation: Explain its practical consequence and include the internal term only when it helps that listener.

The best explanation is the one that helps its intended audience take the next correct step with no more internal detail than that requires.

FAQ

How do I explain software to a nontechnical audience?

Start with a problem the audience recognizes and the task they need to complete. Describe what the product helps them do, show the main steps, and connect each important feature to a visible result. Explain technical terms only when they affect the person’s decision or next action, and pair them with a concrete example.

What if different audiences need different explanations?

Write down what each audience already knows and what they need to decide or do. Then keep details that could change that decision or action, and leave other implementation details for supporting material. A new user and a technical buyer may need different levels of explanation even when they are learning about the same product.

What if a product’s workflow has several conditions or possible outcomes?

Choose the main path that best explains the product’s purpose, and show its cause and effect clearly. Include a condition or alternate outcome when leaving it out could lead to a wrong expectation or action. For example, explain how a payment status changes what happens next if that distinction matters to the audience.
