# Step 1 · Hotel details

Five minutes of work that everything else inherits.

This is the quickest step in the whole setup and the one every other screen inherits. Go to **Settings**, and stay on the **Hotel** tab.

## What to fill in

{% stepper %}
{% step %}

#### Hotel name

What guests should see. It appears on screens, in the browser tab, and in every email Harmony sends. Use the trading name — "Grand Palace Hotel", not "Grand Palace Hospitality s.r.o."
{% endstep %}

{% step %}

#### Hotel logo and hotel image

Choose a file and click **Update**. A PNG with a transparent background, around 200 px wide, works best for the logo. The image is a photograph of the property and is optional.
{% endstep %}

{% step %}

#### Check-in and check-out times

For example `14:00` and `11:00`. These are not just labels — see below.
{% endstep %}

{% step %}

#### Reservation ID prefix and suffix

The text wrapped around each booking number. With a prefix of `RES_` a booking reads `RES_00042`. Leave the suffix empty unless you have a reason.
{% endstep %}

{% step %}

#### Guest ID prefix and suffix

The same idea for guest records — `GID_` gives `GID_00012`.
{% endstep %}

{% step %}

#### Click Save changes

Bottom right of the Hotel tab. It saves **this tab only**.
{% endstep %}
{% endstepper %}

## The two time fields do real work

Check-in and check-out times are the reference point for:

* the arrival and departure times the booking wizard suggests;
* which bookings count as "arriving today" and "departing today" on the reception dashboard;
* the **Late check-out** service on a booking;
* any automation you write around arrival or departure.

Use the hotel's real published policy. If weekends differ, use the weekday value — reception can adjust an individual booking.

## Choosing ID formats

| Goal                  | Prefix                    | Result                                             |
| --------------------- | ------------------------- | -------------------------------------------------- |
| Plain and obvious     | `RES_` / `GID_`           | `RES_00042`                                        |
| Match an existing PMS | whatever that system uses | fewer mistakes when staff compare the two          |
| A group of properties | `GP-RES-`                 | `GP-RES-00042` — obvious which hotel it belongs to |

{% hint style="warning" %}
**Decide the prefixes before the first booking.** Changing one later does not renumber bookings that already exist, so you end up with two formats in the same list.
{% endhint %}

## Confirm it worked

* [ ] Reload the page — your values are still there
* [ ] The browser tab on any Harmony page shows the hotel name
* [ ] A new booking in Reception defaults to your check-in and check-out times
