Free gaps are drawn inside the day, so you can answer “what have you got on Thursday?” while they are on the phone. The calendar is at [BACKOFFICE › Treatments › Calendar](https://app.zeropos.shop/planning/treatments). The week strip moves you between days; on a computer the month sits beside the day. Where to find it: BACKOFFICE › Treatments › Calendar. ## Before you start - At least one treatment marked **Can be booked as an appointment**: [Turn on treatments](https://zeropos.shop/help/enable-treatments). ## Steps 1. Open [BACKOFFICE › Treatments › Calendar](https://app.zeropos.shop/planning/treatments). 2. Pick one shop at the top. Free times only show for a single shop, never for **All shops**. 3. Go to the day, then tap **Book** on a free gap. The form opens at that time. - No gap at the time you need? Tap **New appointment** and type the time yourself. 4. Fill in the **Customer**: search by name, phone or email, or just type a name. - With **Book and gift to a named customer** switched on, pick them from the list or add them. 5. Choose the **Treatment**. Its length decides how much of the day it takes. 6. Check the **Date** and the time, already filled in from the gap you tapped. 7. Leave **Assigned staff (optional)** on **— Anyone —** or pick a person, and add **Notes** if needed. 8. Tap **Book appointment**. ## What happens next - The appointment appears in the day, marked **In-store**, and in the **Appointments** list. - On the day it also shows at the till under **Booked in today**, for whoever is serving. - Nothing is charged when you book. The customer pays at the till when they come: [Treatments at the till: today's bookings and treatment gifts](https://zeropos.shop/help/treatments-at-the-till). - To change who does it, mark it done or a no-show, cancel it or move it, see [Look after appointments: find, mark done or no-show, cancel](https://zeropos.shop/help/manage-appointments). ## Common questions ### Why does a day show no free times? Free times come from the shop's opening hours, set in the shop's form in [MANAGE › Locations](https://app.zeropos.shop/backoffice/locations) under **Opening hours**. A day the shop is closed shows no free gaps, but you can still book with **New appointment** and a time you type. ### Do online bookings land here too? Yes. Bookings customers make themselves appear in the same calendar, marked **Online**: [Let customers book online](https://zeropos.shop/help/online-booking). ### The customer has a gift voucher. Do I enter it here? No. They show the voucher when they come in, and you check it on the Gift vouchers screen: [Treatment gift vouchers](https://zeropos.shop/help/treatment-vouchers). ## If you see this - “**That time slot is already booked.**” — What to do: Every treatment room at this shop is taken for part of that time ([Treatment rooms and who does each treatment](https://zeropos.shop/help/rooms-and-staff)). Pick another time or another day. - “**Ana already has another appointment at that time.**” — What to do: The person under **Assigned staff (optional)** is doing another treatment then, at this shop or another. Pick someone else, **— Anyone —**, or another time. - “**Pick the customer from the list, or add them, before booking.**” — What to do: Your shop books to named customers only. Search for the customer and pick them, or add them if they are new. - “**Pick a single shop above to see which times are still free.**” — What to do: Choose one shop instead of **All shops** at the top of the calendar. - “**Nothing booked, and no opening hours set.**” — What to do: With **All shops** selected, pick one shop first. Otherwise this shop has no opening hours for that weekday: set them under **Opening hours** in [MANAGE › Locations](https://app.zeropos.shop/backoffice/locations), or book with **Add an appointment** and type the time. ## Related guides - [Look after appointments: find, mark done or no-show, cancel](https://zeropos.shop/help/md/en/manage-appointments.md) - [Treatment rooms and who does each treatment](https://zeropos.shop/help/md/en/rooms-and-staff.md) - [Let customers book online](https://zeropos.shop/help/md/en/online-booking.md) - [Treatments at the till: today's bookings and treatment gifts](https://zeropos.shop/help/md/en/treatments-at-the-till.md) - [Treatment gift vouchers](https://zeropos.shop/help/md/en/treatment-vouchers.md)
