For example, add a Service with a start time and duration.

Choose booking cutoff. For example, 1 day means clients can start booking for tomorrow. 1 week means clients can start booking a week ahead.

For booking start times you have the option of using regular Business Hours, or set custom booking start times for this service.

If you choose 'Custom booking times' you have the option of using start times or start labels. The difference is as follows:

Start time: a list of specific start times, like 9am, 9:15am, 9:30am, etc.

Start label: you can add starting labels and for each set the time range. For example: 'Morning' as 8am to 9am.

Price based on quantity: turn it off to charge a specific amount no matter how many pets are in an appointment.

Add a price rule for additional pets: special rate for additional pets.

Invoice calculation: Select 'Time' so the system can calculate the total amount to invoice based on appointment duration. For example, if the service is 30 minutes long, but the appointment lasts an hour, the system will automatically calculate total amount owing based on time spent. Alternatively, select 'Fixed', if you want the invoiced amount to use service price, ignoring duration of the appointment.

In order for the booking system to invoice clients correctly, there are several options that can be configured for the calculation of amount to invoice for this service.

Charging time unit: You can set it to a specific duration in number of Hours / Minutes / Days or Nights, or you may leave it as 'Service duration'.

For example, a dog walk that's 30 minutes long can keep the 'Service duration'.

Minimum duration to charge for: you may offer a service that you charge for in 1 hour increments, but the minimum booking you accept is 3 hours. 

Rounding unit: you may choose not to round at all, then the system will invoice for the exact duration of the booking (if there's 37 minutes between Checking in and Completing, that's what the client will be charged for). You also have the option to set rounding rules to match your business process.

Set Tipping and Taxes as per your business needs and preferences.

Click on Prepay box to enforce payment when a client is booking. You can set the prepay amount or percent. You can also customize what happens when a client wants to book a series of repeating appointments by setting % of prepayment amount.

Click on Enable Payroll to change how a workers pay is calculated.

Select Do not allow additional service added to the appointment when booking to not allow additional services added to the appointment.
