How to Evaluate a Device Purchase Using Conservative Booking Projections
Short answer: Evaluate a device purchase by modelling three scenarios (conservative, expected and optimistic) using monthly treatments, contribution per treatment and fixed device costs. Base the decision on whether the conservative scenario is acceptable. If the clinic can't absorb the cost when bookings are slow, the purchase carries more risk than the sales projection suggests.
Key takeaways
- Model conservative, expected and optimistic scenarios.
- Use your own booking data, not supplier projections.
- Decide based on the conservative case.
- Ask written questions about contracts, support and consumables.
Why use conservative projections?
Supplier projections often assume steady demand from the first month. In practice, bookings ramp up slowly, staff need training and some months are quieter. A conservative scenario shows the downside you need to be able to manage.
It's easier to celebrate beating a conservative forecast than to recover from missing an optimistic one.
How do you build the three scenarios?
- Monthly treatments for each scenario, grounded in current demand
- Contribution per treatment, including consumables and provider pay
- Monthly fixed costs: financing, service, insurance
- Monthly result = treatments × contribution − fixed costs
- Months to cumulative break-even
Answer the purchase questions on contract length, support, consumable pricing and resale before you sign.
How does the device scenario model help?
The scenario model sets out three scenarios, a hypothetical example and a list of purchase questions.
Resource 048 is organized into these sections:
- Model three scenarios
- Hypothetical example
- Purchase questions
For the calculation, use tab “048 Device scenarios” in the Aesthetic Intelligence Calculation Workbook. Blue cells are editable inputs.

Frequently asked questions
Where should booking estimates come from?
Your existing patient base, current demand for similar treatments and waitlist data.
What if the conservative scenario loses money?
Consider waiting, leasing, renting a device short term or negotiating terms.
Should financing be part of the model?
Yes. Include financing costs as monthly fixed costs. Resource 049 compares acquisition options.
