Getting Started

Setup

Installing the app

At9 is available for free on both iOS and Android. Search for At9 in the App Store or Google Play, or tap the download links on the At9 website.

The app works on both phones and tablets. The same account works across all your devices and keeps everything in sync automatically.

💡

Tip: On a tablet, At9 shows a wider schedule view with more entities visible at once — ideal for a desk or counter setup.

Registering

Open At9 and tap Create account. Enter your name and email address, then choose a password. You'll receive a verification email — tap the link inside to confirm your address and activate your account.

Once verified, sign in and you'll be taken to the setup flow where you can configure your organisation.

💡

Note: If you've been invited to join an existing organisation, follow the link in your invitation email instead — it will walk you through registration and add you automatically.

Registering your organisation

After verifying your email, At9 will prompt you to set up your organisation. Enter your business name, then add your first bookable entity — for example, a room name, table number, or kennel name.

You can add more entities and adjust settings at any time from Admin → Entities once you're up and running.

💡

Tip: Don't worry about getting everything perfect at setup. Add one or two entities to get started — it's easy to rename, reorder or add more later.

Joining an organisation

If someone has invited you to their organisation, you'll receive an email with a link. Tap that link to open At9 (or download it first if you haven't already), then follow the prompts to create your account or sign in.

Once you complete sign-in, you'll be added to the organisation automatically with the role your admin assigned — no extra steps needed.

Bookings

Adding bookable entities

Entities are the resources your customers book — rooms, tables, kennels, treatment rooms, or any space or asset in your business. You need at least one entity to take bookings.

To add or manage entities, go to Admin → Entities. From there you can:

Add a new entity — give it a name, type, and maximum occupancy.
Edit an existing entity to update its name or capacity.
Reorder entities by dragging them into position — this controls the column order on your schedule.

💡

Tip: Use specific names — "Garden Room" rather than "Room 1" — so entities are easy to tell apart at a glance.

Creating a booking

You can start a new booking in two ways:

From the schedule: tap the + button, or tap directly on an empty slot for a given entity and time.
From anywhere: tap the floating add button at the bottom-right of the main view.

In the booking form, fill in:

Customer — search for an existing customer or add a new one.
Entity — the room, table, or resource being reserved.
Start and end date/time — At9 checks availability for the chosen entity as you fill in the dates and warns you of any conflicts before you save.

💡

Checking availability: switch to the Availability tab within the booking form to see which slots are free across all entities for your chosen dates — useful when a customer isn't set on a specific room.

Updating a booking

Tap a booking on the schedule to open its detail panel, then tap Edit. The booking form opens with all current details pre-filled.

You can update:

Start and end date or time.
The assigned entity (room, table, etc.).
Customer details.
Any notes attached to the booking.

At9 checks availability again when you save, so you'll be warned if your changes would create a conflict with another booking.

Moving a booking

You can move a booking to a different time or entity directly on the schedule without opening the edit form.

Press and hold a booking block until it lifts.
Drag it to the new time slot or entity column.
Release to drop it — At9 saves the change automatically.

💡

Tip: If a customer calls to switch rooms, you can drag the booking across to the new entity column in seconds — no need to open the edit form at all.

Setting booking preferences

From Admin → Settings, you can configure how bookings behave across your organisation:

Default duration — the pre-filled length of a new booking, so you don't have to set it every time.
Buffer time — an automatic gap added between back-to-back bookings to allow for cleaning or turnaround.
Double-booking — choose whether At9 blocks overlapping bookings on the same entity or allows them with a warning.

💡

Tip: Setting a sensible default duration saves time when creating bookings and helps keep your schedule consistent.

Managing Teams

Inviting users to your organisation

Organisation admins can invite team members from Admin → Team. Enter the email address of the person you'd like to add, choose their role (Admin or Member), and send the invite.

They'll receive an email with a link to create their account or sign in to At9. Once they do, they'll be added to your organisation automatically and can see the schedule straight away.

Admins can manage entities, settings, and invite or remove team members.
Members can view the schedule and create or update bookings, but cannot change organisation settings.

💡

Tip: You can remove a team member or change their role at any time from the same Team screen.

Joining an organisation

When an admin invites you, you'll receive an email from At9 with a personal invitation link. Tap that link to open the app (or download it first if needed), then create your account or sign in with an existing one.

You'll join the organisation automatically with the role your admin selected. Your subscription is managed by the organisation — you won't need to set up billing separately as a team member.
