Waitlist Management: How to Fill Last-Minute Cancellations Instantly
A cancellation at 4 PM for tomorrow at 9 AM is stressful. You have a gap. You lose $150. Meanwhile, you have 3 clients desperate to see you.
Matching that supply and demand efficiently is the difference between a thriving practice and a burnout one.
The Waitlist Process
1. Manual List (Excel/Notebook)
- Pros: Free.
- Cons: You have to call/text people one by one. "Hey, want 9am?" "No." "Hey, want 9am?" "No." It takes an hour.
2. The "Broadcast" Method (BCC Email)
- Pros: Fast.
- Cons: "First to reply wins" can feel chaotic.
3. Automated Waitlist (Software)
- Pros: Client adds themselves to a list. When a slot opens, the system emails them.

Specific Client Offer (The "VIP" approach)
Subject: Thinking of you - Spot open
Hi [Client Name],
I know we've been trying to find a time for you. A spot just opened up for tomorrow at 9 AM. Since you're on my priority list, I wanted to offer it to you first before I post it widely.
Let me know by 5 PM if you want it?
Guardrails (Ethics)
- Don't Pressure: Always frame it as an opportunity, not an obligation. "No pressure if this doesn't work for you."
- No "Bidding": Never auction spots. The price is the price.
- Clinical Appropriateness: Don't offer a slot to a high-risk client if you haven't seen them in 6 months without doing a proper intake.
Prevention vs Cure
The best way to manage cancellations is to prevent them.
- Deposits: See our guide on Collecting Deposits.
- Reminders: See our Reminder Templates.
