# Check-in and walk-in line

> Let customers say they have arrived and organize the line of people who come without an appointment.

## What it is for

Two front desk tools, set up per calendar:

* **Check-in**: a customer with an appointment lets you know they arrived.
* **Walk-in line**: people without an appointment join through a QR code or link, get a ticket, and wait their turn.

## Who can use it

For the **Walk-in line**, Supervisors can also edit; Operators can only view. For **Check-in**, the Owner and Admins set it up on the Settings screen. It appears if the agency enabled the Agenda module for the organization.

## Where to click

In **Calendar**, go to the **Settings** tab and choose the calendar. The **Check-in** and **Walk-in line** sections are in its settings. If the line is on, the **Line** view appears next to Day, Week, Month, and List.

## Step by step: check-in

**1. Turn it on and set the window**

Under **Check-in**, turn it on and enter **Minutes before the time** (from 5 to 240) and **Minutes after the end** (from 0 to 240).

**2. Use the front desk QR**

Under **Front desk QR**, use **Download**, **Print**, or **Copy link**. With check-in on, the reminder gets the line "Arrived? Let us know here".

**3. Follow along in the calendar**

Open the appointment: **Mark arrival**, **Serve**, and **Undo arrival**. You can see who let you know: through the reminder link, through the front desk QR, or marked by the front desk.

The customer taps **I'm here** (through the link) or types the phone number on the appointment on the "Here for your appointment?" page (through the QR). Then they see "Done, we let them know!".

## Step by step: walk-in line

**1. Turn on the line**

Under **Walk-in line** in Settings, set **Maximum in line** (1 to 500) and "Send 'almost there' when" (0 to 10; 0 = off). Click **Save** and then use the **Line QR code** (**Download**, **Print**, **Copy link**). **Change QR** invalidates the printed code.

**2. Open today's line**

In the **Line** view, click **Open today's line**. **Close the line** stops new people from joining.

**3. Serve people**

Use **Call next**, then **Serve** and **Finish**. Other actions: **No-show**, **Back to line**, and **Remove**. For people who arrived without a phone, use **Add**.

## What happens next

A customer who joins the line sees the **Your ticket** page with their position, which updates by itself, and gets the "it's your turn" notice on WhatsApp. The numbers appear in Reports, under **Walk-in line**: Joined, Served, Gave up, No-shows, and average wait.

## Common errors

* "It's still early. Arrival check-in opens at …" / "The time to check in has passed."
* "We couldn't find an appointment today for this number."
* "Line turned off": turn it on in the service settings.
* "The line is full right now." / "This WhatsApp is already in line."
* "The line is closed right now."
* "Too many attempts. Wait a minute and try again."
