Here's how to take money off a single appointment, with one of your discounts or with a one-off discount just for this booking. The discount is carried onto the appointment's invoice.
Add one of your discounts
Open the appointment, or start booking a new one.
Scroll to Total and tap Discount.
On Add discount, tap + beside the discount you want. Tap + again to add it more than once, like two lots of "Loyalty".
Tap the ✓ to save.
Save the appointment. On a repeating appointment, choose Save for this appointment only or Save for future appointments.
Add a one-off discount
Scroll to Total and tap Discount.
Tap Add one-off discount.
Give it a name, like "Goodwill". Your client sees this name.
Choose Fixed amount or Percentage, and add the amount.
To take it off more than once, tap + on the count under the amount.
Tap the ✓. You're back on Add discount, with the one-off at the top.
Tap the ✓ to save, then save the appointment.
A one-off is only for this appointment. It isn't saved to your Discounts.
What's on Add discount
Can apply: your discounts that match this appointment, with what each one takes off. Discounts with Automatically apply turned off are listed too, marked Manual, so you can still add them by hand.
Does not apply: discounts whose limits don't match this appointment, like ones for another client or service. You can't add these.
Already added: a discount that's on the appointment already, with what it takes off each time.
Create discount: saves a new automatic discount to your Discounts. If it matches the appointment, you can then add it here.
Change or remove a discount
Tap a discount's row under Total. One of your discounts opens Add discount, where you can change how many times it's taken off. A one-off opens so you can change its name, amount or count.
To remove one, swipe left on its row and tap the delete button. On Android, tap the row and choose Remove.
An automatic discount you remove isn't added back to this appointment, even when you change it. Add it again from Add discount if you need it.
Good to know
Your automatic discounts are added for you when the appointment matches them. You only need Add discount for anything extra. See How do I set up an automatic discount?
A one-off discount on a repeating appointment comes off every visit you save it for.
The discounts are carried onto the invoice, however it's made: when booked, when started, automated, or from the appointment's ... menu.
Changing the discounts after the appointment has been invoiced doesn't change the invoice. Change the invoice itself. See How do I add a discount to an invoice?
On a group appointment, each client's invoice only gets their share: a percentage comes off each client's own services, and a fixed amount comes off once, for the client whose pets it's for, or else the first client.
You can't change the discounts on an appointment your client paid for when they booked it.
Only admins and sub-admins can add discounts.
