Practical guide
How to stop double booking clients when your team uses different apps.
Double bookings happen when more than one place holds your availability, such as a paper diary, a messaging app and a booking tool. The fix is a single schedule that every booking goes into. Nexis Business OS gives the whole team one calendar and one online booking link, so a booked slot is no longer available to the next client. Nexis Business OS combines online booking, a bio site, a client CRM, a WhatsApp team inbox with an AI assistant, an online store, stock and checkout, café menu and orders, online payments and finance. Starter is $49.99 a month and Pro is $149.99 a month, with a 7-day free trial of full Pro and no payment at signup.
7-day free trial of the full Pro plan with 150 free AI tokens. After the trial, choose Starter at $49.99 USD/month (200 AI tokens a month) or Pro at $149.99 (750 AI tokens a month).
Is this the right workflow for you?
For teams of two or more who take bookings by link, message and phone. Check how your own flow works in the trial. Nexis does not sync with Google Calendar or Outlook in the published offer, so move all bookings into the Nexis calendar rather than keeping two.
Follow the setup and decision checklist
- 01Choose one source of truth
Decide that the Nexis calendar is the only place that holds availability.
- 02Route every booking into it
Send clients to your booking link. Enter phone and message bookings into the same calendar straight away.
- 03Set each person’s hours
Configure working hours per team member so only real availability can be booked.
- 04Retire the old diary
Stop using the paper diary or second app once the team trusts the calendar.
Test the complete journey
See what your team receives after the customer acts.
Use a sample enquiry or appointment in your workspace. Check the customer record, internal schedule and next task. Verify external messages and CRM transfers in the connected service itself.
A proposed workflow change
An operational example to evaluate in your trial, not a customer case study or a promise of results.
Without a connected process
The same slot is promised in a chat, in a diary and through a link.
With the Nexis Business OS workflow
One calendar shows who is booked when, and the booking link only offers free slots.
Check before you launch
- Book a slot by link and confirm it disappears from availability.
- Enter a phone booking and check the same slot is blocked.
- Check each team member’s hours.
- Agree one rule for changes and cancellations.
