Presentation Mistakes That Cost Deals
Most deals are not lost on the slides. But some are, and the ones that are tend to be lost the same handful of ways.
Here they are, grouped by where the damage happens. A useful framework for clear ownership and reliable delivery is read more here.
Structural failures
Burying the point. Building to a conclusion on slide fourteen when the audience decided on slide three. Lead with what you want them to conclude, then support it. This is the opposite of how most people write, and it is why so many decks feel slow.
No stated ask. A presentation that ends without a specific request leaves the other side to invent a next step, and they usually invent "let us think about it." State what you want, precisely.
Answering questions nobody asked. Company history, team biographies, and a tour of your process before establishing why any of it matters. Keynote-specific behaviour is documented in the Apple Keynote user guide.
One deck for every audience. A procurement manager and a founder want different things. Sending the same deck to both means it is wrong for at least one.
Failures in the room
Reading the slides aloud. The audience reads faster than you speak. Reading to them is both slower and mildly insulting, and it guarantees they stop listening.
Slides too dense to present. If a slide has a paragraph on it, the room reads it silently while you talk. You are competing with your own material. See how much text belongs on a slide.
Not testing the equipment. Projectors clip edges, wash out contrast, and mangle colour. Fonts substitute on borrowed laptops. Videos fail without the right codec. Ten minutes of testing prevents the opening five minutes of apology.
No plan for the deck failing. Bring a printed copy, or be able to make the argument without slides. A presenter who continues confidently when the screen dies gains more than they lose.
Ignoring the room's pace. Sixty slides in a thirty-minute slot means either rushing or not finishing. Both read as poor preparation.
Failures in the inbox
Sending the presented version. Sparse slides designed for narration communicate almost nothing when forwarded. If the deck will be circulated, it needs written explanation on the slides or a summary document alongside.
Enormous file size. A 90 MB attachment does not arrive, or does not get opened. Compress images and export properly.
Sending an editable file when a PDF would do. PDFs preserve fonts and layout, cannot be accidentally altered, and open reliably everywhere.
No context in the email. A deck attached to "as discussed" reaches someone who was not in the discussion. Two sentences framing it costs nothing.
Design failures
Unlabelled charts. No axes, no units, no time period, no source. The chart works while you narrate it and fails the moment the deck is forwarded.
Charts that mislead. Truncated axes on bar charts, dual axes with arbitrarily chosen scales, 3D perspective distorting comparisons. Sometimes deliberate, more often accidental — and being caught at it costs more than the point was worth. See choosing the right chart.
Inconsistent formatting. Three fonts, four shades of the brand colour, misaligned elements, chart styles that change slide to slide. It reads as carelessness, and the audience generalises from it.
Low contrast. Light grey on white looks refined on a calibrated monitor and disappears on a projector in a bright room.
Decorative stock photography. The generic handshake, the diverse team laughing at a laptop. Adds nothing and signals filler. Empty space is better.
Animation for its own sake. Elements flying in from four directions slow the presentation and distract. A simple appear or fade, used to control reveal order, is the only animation most decks need.
Content failures
Numbers without sources. Every figure needs an attribution. One unsourced claim invites doubt about all the others.
Vague claims. "Significant growth," "industry-leading," "substantial savings." Give the number or drop the claim.
Overstating traction. People compare notes. A deck that inflates gets remembered, and the reputational cost outlasts the meeting.
Ignoring the obvious objection. Everyone in the room is thinking about the same risk. Addressing it directly builds credibility; leaving it unmentioned means they think about it instead of listening.
Typos. Unfair, but real. A misspelling in a headline undermines everything about your attention to detail, at the exact moment you are asking to be trusted with something.
Regional considerations
Assuming one register. The investment and corporate landscape in the Gulf spans institutional family offices, sovereign-linked entities, and young firms with entirely different norms. Research the specific organisation.
Pushing for commitment too early. In relationship-driven markets, the first meeting is often about establishing who you are. A deck engineered to close in the first conversation misreads the sequence. See pitching to Gulf investors.
The pre-meeting checklist
- [ ] The ask is stated explicitly on a slide
- [ ] Every chart has axes, units, period, and source
- [ ] Every number has an attribution
- [ ] Spelling checked by someone who did not write it
- [ ] Tested on the actual display, or a comparable one
- [ ] Exported as PDF for sending
- [ ] File size under 20 MB
- [ ] Slide count fits the time slot with room for questions
- [ ] The main objection is addressed somewhere
- [ ] You can make the argument if the screen fails
The last item is the one that separates a presentation from a slideshow. If the deck is the argument, you are in trouble when it breaks. If it supports an argument you can make anyway, nothing that goes wrong in the room is fatal.
