Start with the request. Finish with a saved appointment. Between those two events, check the things that could turn a reasonable-looking time into a bad commitment.
1. Confirm what the customer needs.
Use the service you actually offer, rather than a vague label like “repair.” Decide whether the request can be booked routinely or needs review. Do not solve uncertain scope by assuming a shorter appointment.
2. Separate coverage from travel.
A service-area ZIP answers whether the business serves a place. A confirmed street address is needed for the route check. A team member may also have narrower coverage than the business as a whole.
3. Find the eligible person.
Check their services, coverage, working hours and timezone. An available person who cannot handle the service is not an available booking option.
4. Read the calendar as it is now.
Check connected calendars as well as appointments in the booking system. Do not rely on the view someone opened earlier in the morning. If the connection is stale or unavailable, resolve it before promising the time.
5. Calculate travel on both sides.
Imagine the previous appointment ends at 10:50, the drive takes 20 minutes, and the buffer is 10 minutes. The earliest arrival is 11:20. A one-hour visit would end at 12:20.
If the next visit begins at 12:45 and is 20 minutes away, another 10-minute buffer means departure must be no later than 12:15. The 11:20 appointment still does not fit. Checking only the inbound drive misses this.
Previous end + drive + buffer must fit before the start. New end + drive + buffer must fit before the next start.
6. Recheck at booking time.
Two people can select the same opening, or another calendar event can appear after the search. The final booking must revalidate availability and prevent overlapping commitments. If the slot is no longer available, return to the available options.
7. Verify the saved result.
Keep the lead attached to the appointment. Confirm the date, timezone, person and address. If the connected-calendar update is pending or failed, make that visible to the office and provide a recovery action.
What to test before rollout
- A valid appointment between two nearby visits.
- A slot that fits the calendar but fails the outbound drive.
- An ambiguous address and an out-of-area ZIP.
- A disconnected calendar and provider timeout.
- Two people trying to book the same opening.
- Rescheduling and cancellation with calendar readback.
Travel estimates cannot predict every road condition. Set buffers around the service you deliver and review real exceptions after the pilot.
