What actually cuts demo no-shows?
Five habits cut demo no-shows: book the call soon after the person agrees, get the invite accepted before you hang up, confirm in writing with an agenda, remind them with a one-click way to reschedule, and chase within minutes when they miss it. The first one has the clearest published numbers we found.
Reply.io, which sells outreach and booking software, analysed 2,900 meetings booked with its own sales team over a few months and published the results in an August 2023 post on demo no-shows. These are Reply.io's own figures, from one company's pipeline:
| Gap between booking and the demo | No-show rate in Reply.io's data |
|---|---|
| Same day | 6.9% |
| Next day | 9.6% |
| 0 to 7 days | 12.4% |
| 8 days or more | 23% |
| All demos | 13.3% |
Reply.io acted on it. Its website forms and chatbots only let prospects book 10 to 14 days ahead at most, and when its team books qualified prospects it usually offers up to 7 days. You can set the same kind of limit yourself. Google Calendar's appointment schedule settings, for example, include a maximum time in advance someone can book and a minimum lead time, which defaults to four hours.
One company's data won't match your market. Treat the table as the buckets to track your own demos by, and look at your own split after 20 or 30 bookings.
What are the signs someone won't show up?
An invite that was never accepted is the sign salespeople named most, at least in one busy thread. In an r/sales thread from August 2026 asking for the biggest indicator of a no-show (about 69 comments when checked on 24 October 2026), the most upvoted reply was six words: "They don't accept the calendar invite". The next two were rescheduling more than once and a Friday afternoon slot. These are commenters' experiences, not measured data, but the same few signals came up repeatedly in the thread:
| Warning sign | What commenters described | What to do |
|---|---|---|
| Invite not accepted | Top reply in the thread | Ask them to accept while you are still on the call or in the thread |
| Rescheduled twice | Second most upvoted reply | Ask what changed before offering a third slot |
| You had to push for the meeting | Several said prospects agree to get a seller off the phone | Stop at the second ask and send something useful instead |
| You moved your hours for them | One commenter called it a near-certain no-show | Offer your normal slots first |
| No named problem | One commenter: people who named a specific thing to fix turned up | Ask what they want from the call before you book it |
| No reply to the reminder | Listed with an unaccepted invite and two reschedules | Send one short "still good for Thursday?" note |
Don't cancel on a missing RSVP alone. In the same thread, one commenter said many European prospects never accept invites but still turn up, and another skipped calls with no RSVP, then lost a deal by missing a prospect's email asking whether they were on the call. Treat the signs as a reason to reconfirm, and still join the call.
How do you qualify a demo before you book it?
Book the demo only after the person has named the problem they want solved. One commenter in the r/sales thread put it plainly: no-shows happen mostly when not enough interest has been built. A prospect who says "we lose leads between the form and the first call" has a reason to turn up. A prospect who says "sure, send an invite" to end the conversation does not.
Three checks before you send the invite:
- The problem in their words. Write it down. You will put it in the invite.
- The right person. If they can't decide or influence the purchase, ask who else should join. Our guide to qualifying a lead in the first ten minutes covers the questions.
- A time inside your booking window. If they can only do three weeks out, book it, then put a short check-in on your calendar for the week before.
One habit from a former SDR in the same thread is worth copying: at the end of the booking call, ask what you should cover so the call is worth their time. In our words: what should we cover on Thursday so it's worth your 30 minutes? Their answer becomes your agenda. If the demo follows a discovery call, our list of discovery call questions for founders doing their own sales gives you the questions that surface it.
What should the confirmation and reminders say?
The confirmation should repeat their problem, list the agenda and make rescheduling easy. Send it within minutes of booking. Here is a version you can copy:
For reminders, Reply.io's post suggests at least three emails: a thank-you right after booking, a check-in the day before, and a reminder 30 to 15 minutes before the call. Make the day-before note specific. One commenter in a September 2025 r/sales thread about customers skipping check-in calls (about 46 comments when checked on 24 October 2026) suggested mentioning something from their world instead of sending a bare confirmation. A day-before reconfirmation:
One commenter in the August thread asks prospects to click yes or no on a confirmation before the call, and treats no response as a likely no-show. If you want more wording for the first ask, our meeting request email templates cover the step before the booking.
Which booking tools send reminders and reconfirmations?
All three tools below can send reminders, and on two of them automatic reminders need a paid plan. Here is what each vendor's own pages say, checked 24 October 2026:
| Tool | Reminders and confirmation | Plan needed |
|---|---|---|
| Google Calendar appointment schedules | Up to 5 email reminders; you can't edit the reminder text. Guests can answer Yes, No or Maybe and propose a new time | Automatic reminders are listed as a premium feature (eligible Workspace or Google One plan) |
| Calendly | Reminder and reconfirmation emails or texts; invitees confirm with a "Yes, I'm attending" button | Standard, $10 a seat a month billed yearly or $12 billed monthly; Free has no automations |
| Cal.com | Email and SMS notifications on the free plan; customisable ones on Teams | Free; Teams $12 per user a month billed yearly |
The sources: Google's premium features chart for appointment schedules and its help page on responding to invitations; Calendly's reconfirmation help page and pricing page; and the Cal.com pricing page.
Calendly's automations overview (updated September 2026) also lists "No-show marked" as a trigger, so the reschedule email can go out on its own once you mark the meeting. If you'd rather keep booking in the same place as your leads, Siela's calendar and booking pages check every connected calendar and send reminders.
What do you do when someone doesn't show?
Email two to ten minutes after the start time and offer a new slot. Reply.io's post recommends a short ping two minutes into the call. A commenter in the September 2025 thread waits ten minutes and writes "Do we need to reschedule?", which gives the prospect an easy way out without an apology. Send this:
Then mark it. In Calendly, the Mark no-show option appears only after the meeting's start time, and invitees marked as no-shows don't get the usual follow-up emails unless an automation targets no-shows. That stops a thank-you email going to someone who never turned up.
If there's no reply, Reply.io's no-show sequence runs for ten days: an email and a LinkedIn touch on day 1, a call on day 2, an email with a personalised video plus a text on day 4, a call on day 7, an email on day 8 and a LinkedIn voice message on day 10. The company says it wins back 10 to 20% of those opportunities on average, a self-reported figure. A founder can run a lighter version: the ten-minute email, one follow-up three days later that shares the agenda you had planned, then stop. Our guide to what to send when a prospect goes silent has the wording for that last message.
How do you track no-shows this week?
Start a log today. After 20 or 30 bookings you will see where your no-shows cluster. Add one row per booked demo with these columns:
- Date booked and date of the demo (the gap in days is the column that matters)
- Where the lead came from: inbound form, cold email, LinkedIn, event, referral
- Invite accepted (yes or no) and reconfirmation reply (yes, no, none)
- Showed, rescheduled or no-show
Here is the arithmetic on hypothetical numbers. Say you book 16 demos a month, and each no-show costs you 20 minutes of prep plus a 30-minute slot. Four no-shows cost 200 minutes, about 3.3 hours a month. If a shorter booking window and a reconfirmation email turn two of those into shows or early reschedules, you get back about 1.7 hours and two real conversations.
Then sort by gap and by source. If demos booked more than a week out miss more often, shorten your booking window. If one source misses far more than the others, qualify those leads harder before you send the invite.
Frequently asked questions
What is a normal no-show rate for sales demos?
We found no independent benchmark we would trust. The cleanest published number we found is Reply.io's own: 13.3% of 2,900 demos booked with its sales team, published in August 2023, rising to 23% when the demo was eight or more days after booking. One r/sales commenter selling to small and medium business owners reported 40% across their team. Measure your own rate before you compare.
Should you cancel a demo if the prospect hasn't accepted the invite?
No. An unaccepted invite was the most upvoted warning sign in an August 2026 r/sales thread, but one commenter in the same thread said many European prospects never accept invites and still turn up. Send a short reconfirmation the day before, then join the call anyway and wait a few minutes before you email.
How far in advance should you let prospects book a demo?
Reply.io's website forms only allow bookings 10 to 14 days ahead, and its team usually offers up to 7 days to qualified prospects. In its own data, 12.4% of demos booked within a week were no-shows, against 23% for those booked eight or more days out. Most booking tools, including Google Calendar appointment schedules, let you set a maximum time in advance.
Do Calendly reminders work on the free plan?
No. Calendly's pricing page, checked 24 October 2026, lists automations and reminders under the Standard plan, at $10 a seat a month billed yearly or $12 billed monthly. Marking a meeting as a no-show works on all plans, but sending an automatic reschedule email to no-shows needs Standard or higher.
What should you send after a demo no-show?
Send a short email two to ten minutes after the start time that offers a new slot with a reschedule link and no blame. If there's no reply, send one follow-up a few days later with the agenda you had planned, then stop. Mark the meeting as a no-show in your booking tool so post-meeting emails don't go out.
