# No Availability

If your calendar shows no available time slots, check the following common causes.

## 1. No Availability Set for Resource

The most common issue. Every resource needs an availability schedule.

**Fix:**

1. Go to **Sesami > Resources > \[resource] > Availability**
2. Set available hours for each day
3. Click **Save**

{% hint style="warning" %}
Don't forget to click **Save** after setting availability — unsaved changes won't apply.
{% endhint %}

## 2. Duration Variant Is Incorrect

Sesami reads the product's "Duration" variant to determine time slot length. If it's missing or formatted incorrectly, no slots will appear.

**Requirements:**

* The option name must be exactly **Duration** (case-sensitive, no trailing spaces)
* Values must use a recognized format: `30`, `45 m`, `90 minutes`, `3h`, or `1 hour`
* Time frames must be between 00:00 and 24:00 on one day

**Fix:**

1. Go to **Shopify > Products > \[your service product]**
2. Check the **Variants** section
3. Ensure option name is `Duration` (no extra spaces)
4. Ensure option values are in a valid format
5. **Save** the product

## 3. Sesami Not Activated in Theme (Online Store 2.0)

If you're using a Shopify Online Store 2.0 theme, you need to embed the Sesami app in your theme.

**Fix:**

1. Go to **Shopify > Online Store > Themes > Customize**
2. Enable the **Sesami app embed**
3. Add the **Sesami block** to your product page template
4. **Save**

## 4. Sesami Tag Was Removed

For Online Store 2.0 themes, Sesami automatically adds a tag to products. If it's been removed, the calendar won't appear.

**Fix:** Re-save the service assignment in Sesami, or re-add the Sesami tag to the product.

## 5. Conflicting Booking App

Having another booking app installed can cause conflicts.

**Fix:** Uninstall other booking apps from your Shopify store before using Sesami.

## 6. Inventory Tracking Is Enabled

If "Track quantity" is enabled on the product, customers may see "Sold out" instead of the calendar.

**Fix:**

1. Go to **Shopify > Products > \[your service product]**
2. Uncheck **Track quantity**
3. **Save**

## Still No Availability?

If none of the above resolves the issue:

* Check your [timezone settings](/booking/availability/timezone.md) — mismatched timezones can hide slots
* Check [buffer times](/booking/availability/buffer-times.md) — large buffers may eliminate available slots
* Contact support: <help@sesami.co>
