An indicative estimate based on your own figures. Adjust the assumptions to see different scenarios.

How it is calculated

No magic: it is a simple, transparent estimate based on your own figures. The formula is this:

Unanswered enquiries × % who wanted to book × % who never try again × average appointment value = daily loss. Multiplied by the days you open per month (and by twelve) gives you the monthly and yearly loss.

Both percentages are adjustable because every business is different. By default we use conservative assumptions (half the enquiries are looking to book and some of them never try again), but you can move them to see your real scenario. It is a guide for deciding with numbers, not an exact figure.

It works for any appointment-based business

If your business runs on appointments, the problem — and the calculation — is the same, whatever your sector.

  • Hair salons
  • Dental clinics
  • Beauty clinics
  • Physiotherapy
  • Garages
  • Professional services
  • Massage studios
  • Spa and wellness

The way not to lose those appointments is simple: always answer

An AI virtual assistant answers your business's calls and messages at any hour and books the appointment for you, so no enquiry is left without a reply.
