How to Build a Custom Presentation Fast Before a Client Call
The call is in forty-five minutes. You have the prospect's name, their company, a rough sense of their problem, and a template deck that was built for a different kind of prospect.
This is the situation account executives and consultants live in constantly. The standard options are: use the generic deck and hope the prospect doesn't notice, or spend the next forty minutes trying to customize it and arrive at the call frazzled.
There's a better path. Here's the step-by-step.
Why Custom Presentations Convert Better
Before the tactics, the principle: custom presentations convert better than generic ones because they remove the prospect's biggest mental objection -- "is this relevant to me?"
When a prospect sees their company name in your second slide, when your problem statement describes exactly what they told you in discovery, when your example uses their industry and their numbers, they're not evaluating whether this applies to them. They're evaluating whether they want to move forward.
Generic presentations shift the burden onto the prospect to make the connection themselves. Custom presentations make the connection for them.
The challenge is time. Proper customization the traditional way takes two or three hours. Here's how to get the same result in twenty to thirty minutes.
Step 1: Pull Your Discovery Notes First (3 minutes)
Before touching any tool, open your notes from the last conversation with this prospect. You're looking for three things:
-
The specific problem they named. Use their language, not yours. If they said "we waste time building one-off decks for every prospect," that exact phrase belongs in your presentation, not "inefficiencies in content creation workflows."
-
A number or detail they gave you. Something specific to their situation: their team size, a metric they mentioned, a deadline they're working toward. Specificity is what makes a presentation feel made for them.
-
The outcome they want. Not the feature they're interested in -- the result they're trying to achieve. "Close more deals faster" or "reduce prep time before calls" or "look more professional with enterprise clients."
If you don't have notes, send a quick message right now asking one clarifying question before the call. "Quick question before we connect -- is the main challenge still [X]?" They'll answer in two minutes and you'll have something to work with.
Step 2: Define Your Three Slides (5 minutes)
Most custom presentations fail because they try to include too much. You don't need twenty slides for a thirty-minute call. You need five to eight.
For a typical sales or consulting call, three slide types carry most of the weight:
The problem slide. Their situation, named specifically. One sentence. Big text. Their words.
The solution slide. What you're proposing and why it addresses the specific problem they named. Not all your features -- the features that are relevant to this prospect.
The proof slide. One example, one stat, or one brief customer story that shows the solution actually works for someone in their situation.
Everything else is optional. Introduction, agenda, pricing -- these can come up in conversation. The three slides above are what make the presentation feel custom.
Step 3: Build the Deck (15-20 minutes)
Now you have structure. Build to it, not around it.
The traditional way (Google Slides, PowerPoint): Open a template, duplicate it, start replacing text. This typically takes forty-five to sixty minutes because you're simultaneously figuring out what to say and wrestling with a layout tool.
The faster way: Build the deck by talking. If you use a voice-first tool like Talkpitch, you open a session, add the prospect's company name and their problem as context, and speak through your three slides out loud. The slides generate as you talk -- within about eight minutes, you have a working deck built around your actual content.
Because you already defined your three slides in step two, you know exactly what to say. You're not figuring anything out -- you're just speaking it. The deck is done before you finish your coffee.
You can build a custom presentation in real time by speaking out loud -- your words become the slides, and you've already practiced your content by the time you're done building. That's a fundamentally different prep experience than fighting with PowerPoint.
Step 4: Review and Tighten (5 minutes)
Once you have a draft:
- Check that the prospect's name or company appears somewhere obvious -- usually slide two or three
- Make sure your problem statement uses their language, not generic language
- Confirm that your ask is clear on the final slide: what specific next step are you proposing?
- Cut any slide that doesn't directly support your three core points
Don't redesign. Don't second-guess the visual choices. You're checking for relevance and clarity, not perfection.
Step 5: Know Your Flex Points
A custom presentation is still a framework, not a script. Know where you're going to pause and invite conversation.
After the problem slide: "Before I continue -- does that description match what you're experiencing right now?"
After the solution slide: "I focused on [X feature] because of what you described last time. Is there a part of this that's more relevant than the rest?"
These pauses do two things: they confirm your customization was accurate, and they turn the presentation from a monologue into a conversation. Prospects who are actively responding are engaged; prospects who are silently watching are often mentally elsewhere.
The Real Time Sink: When You Don't Have Discovery Notes
The scenario above assumes you have good discovery notes. If you're going into a first call or a warm outreach call without prior context, you need a different approach.
Open with questions, not content. Start the call by asking about their situation before you share anything visual. "Before I run through what I prepared, can I ask you two quick questions about how you're handling X right now?" Two minutes of listening gives you the context to make the next twenty minutes actually relevant.
Adapt in real time. If you built a deck based on an assumption that turned out to be wrong, acknowledge it: "I built this around the assumption that [X] was the main challenge -- sounds like it's actually [Y]. Let me adjust how we go through this." Prospects respect the honesty and the flexibility.
Tools That Actually Speed Up Custom Deck Building
A few options, honest assessment:
Google Slides / PowerPoint: Flexible but slow. Good for complex layouts if you have time. Bad for thirty-minute turnaround.
Gamma: Fast from a text prompt. You type a description and it generates a deck. Good when you can type quickly and want polished output. Less useful when you're thinking out loud rather than writing.
Talkpitch: Fast from speech. You talk through your content and slides generate in real time. Best when you know what you want to say but don't want to spend time in an editor. Free tier available; no design decisions required.
Canva: Prettier templates but still requires significant manual input. Better for polished final outputs than fast custom builds.
For most AEs and consultants who build custom decks regularly, the right answer is a voice-first tool for initial builds that get refined as needed. Build fast by talking, clean up in two minutes, go present.
After the Call: The Deck Becomes the Follow-Up
A well-built custom deck doesn't stop being useful after the call ends. After the presentation, send the deck as a follow-up with a cover note that references what you discussed specifically.
"As discussed, [main point you agreed on]. I've attached the deck from today's call -- the [specific section] covers the piece you wanted to review with your team."
This is more effective than a recap email because it gives them something visual to share internally. The person you presented to often has to sell the idea to a colleague or manager. A custom deck -- especially one that names their company and their problem -- makes that internal sell easier.
