Write what the viewer will see as well as what they will hear
A useful SaaS product demo script has two connected parts: narration and screen action. Start with one audience and one task, show the relevant workflow, make the result visible and end with an appropriate next step. A list of benefits without matching product evidence is an advertisement outline, not yet a demo script.
Use the template below for a focused workflow demonstration. Replace every bracket with verified product information. If a feature is planned but not live, do not present it as an available capability. If a claim needs a customer result to support it, use an approved source or remove the claim.
The fill-in script template
Opening: “When [specific audience] needs to [task], [specific obstacle] gets in the way.” Show the starting situation, not a long logo introduction.
Setup: “Here is how [product] handles [one workflow]. We are starting with [input, account role or prerequisite].” Show the real starting screen.
Action: “First, [action]. Next, [action]. Then, [action].” Pair each sentence with the actual control and response. Keep only the steps needed to understand this task.
Result: “Now [visible state or output].” Show that output. Do not replace evidence with an unsupported claim about hours saved or revenue gained.
Next step: “[Try the workflow / view the detailed tutorial / request a tailored demo].” Choose one action that fits where the viewer is in the buying or learning journey.
A worked example: assigning an incoming request
The following is a fictional support-workflow example, not a client script or a description of an actual FDM customer’s capabilities. It shows how to turn a vague feature statement into a demonstrable sequence.
Weak line: “Our powerful platform streamlines collaboration with intelligent automation.” The viewer cannot tell what action to expect or what evidence would support it.
Demonstrable version: “This request has arrived without an owner. Open the request, choose the responsible team and assign a teammate. The owner now appears beside the status, so the team can see who is handling it.” The picture must show the unassigned request, the actual assignment action and the resulting state.
If assignment is automatic in the real product, show the rule and the resulting assignment instead. Do not use the manual sequence just because it fits the template. The script follows the product, not the other way round.
How long should the script be?
Read the narration aloud while performing the actions at a pace the intended viewer can follow. That timed rehearsal is more useful than choosing a word count first. A sentence can be short while the screen action needs several seconds of orientation. Leave room for the viewer to recognise what changed.
Microsoft’s procedural writing guidance recommends task-focused headings and clear individual steps. Applied to a demo, that helps you separate actions instead of burying several clicks in one sentence. It does not establish a universal video length. If the task cannot fit clearly, make a shorter overview and a separate tutorial rather than speeding through every screen.
What FDM’s product work illustrates
FDM’s TikaMobile work includes module-level product walkthroughs. Krista.ai’s explainers use a product or use-case story with interface-led visuals. Both are relevant references, but they serve different levels of explanation: a viewer learning a task needs different detail from a buyer understanding the value.
Before scripting, decide which level you need. A sales-oriented demo may show the key workflow without every setup action. A tutorial must include the prerequisites that let a user reproduce it. Label the film accordingly so a concise overview is not mistaken for complete instructions.

Review the script before recording the final version
Ask a product owner to check every action, label, prerequisite and resulting state. Use a prepared demonstration account with approved sample data, and remove private notifications or customer information before recording. A clean frame is not just a design preference; it prevents irrelevant information from becoming part of the public asset.
Ask a second reviewer to watch the rough sequence without your explanation. Can they say what problem it solves and what changed? Where do they lose the thread? Resolve those points while the script and screen selection are still easy to change. Keep the approved script, capture date and product version with the final files for the next update.
