How we work this out
Each line is volume × the share lost × the share that would have paid × your average value. The starting figures are a typical example for charities; change them to match yours.
- Automatic reminders when customers are due back. We assume 25% of those who would have drifted away rebook.
- Automatic reminders with one-tap confirm or rearrange. We assume no-shows fall by 30%.
- Every WhatsApp, SMS, Instagram and Facebook message lands in one inbox and gets an instant reply. We assume 70% are saved.
These are estimates, not a guarantee.

Questions
How long does it take to set up?
Most businesses are sending their first messages the same day. Import your customers from a spreadsheet or connect your existing software, pick a template and switch it on. We'll help you do it if you'd like.
Can I keep my existing phone number?
Yes. You can move your number to Havari, or use a new UK number alongside it. Your customers won't notice any change.
Is there a contract?
No. Plans are monthly and you can cancel at any time. Every plan starts with a free 14-day trial and no card is needed.
Is it UK GDPR compliant?
Yes. Havari is a UK company, opt-outs are handled automatically on every channel, and your data is stored securely.
What if I need help?
You'll speak to a real person in the UK. Reply to any email from us or call us on 0333 1888 388.
