Before You Start

Before proceeding with the integration, keep the following in mind:
  1. Listings under 1 Smily account cannot be split into multiple PriceLabs account

Step 1: Connecting Smily to PriceLabs

  1. Log into PriceLabs.
  2. Click "Add your listings" (if you have no listings) or "Add/Reconnect Listings" (if you already have listings).
  3. Select "PMS / Channel Manager" and choose "BookingSync" from the dropdown.
  4. Click on Connect with BookingSync

Step 2: Connect & Setup in Smily

  1. Log in to your Smily account.
  2. Set initial rates for all properties in Smily
    1. Navigate to Rentals and click on your property


    2. Access the Rates tab, set a Base Rate, and click Save


    3. Repeat steps for all properties

  3. Navigate to Apps → Visit the App Center


  4. Install and authorize PriceLabs to pull your information and process your data



  5. Once connected, your Smily listings will appear in your PriceLabs dashboard

Step 3: Setting Up Necessary Customizations

A few customizations need to be set up in PriceLabs to be able to successfully sync with your Smily Account.
  1. Minimum Stay Restrictions
    1. Smily integration requires min-stay to be sent from PriceLabs. You can also setup advanced min-stay settings, or date specific min-stay settings - the instructions can be found in Setting Dynamic Minimum Stay Restrictions in PriceLabs
    2. Smily applies Minimum Stay Through, meaning the highest minimum stay requirement within the selected booking period will apply and not the minimum stay upon check out. For example, if a guest wants to book Feb 1 to Feb 3 (3 nights total) but:
      1. Feb 1 has a 2-night minimum stay,
      2. Feb 3 has a 5-night minimum stay,
    3. Then the guest must book at least 5 nights because Smily enforces the highest minimum stay requirement across the selected dates. For more information on this, please check: Understanding the Difference Between Minimum Stay on Arrival and Minimum Stay Through

Step 4: Reviewing & Syncing Prices

  1. Follow the Getting Started guide to set up your listings.
    1. Ensure that the nightly minimum set in Smily matches the minimum price set in PriceLabs. Otherwise, your PriceLabs rates will not sync to your channels.
  2. Review your pricing and settings in PriceLabs.
  3. Enable Sync Prices for automatic updates, or click "Sync Now" to push updates immediately.
  4. Check your Smily account to verify updates
    1. Your PriceLabs rates will appear under Rentals → Property → Rates as shown below

Additional Setup Options/Features Supported

Length of Stay Pricing Adjustments




You can now set discounts or premiums based on the length of stay for Smily listings. This feature is available on request and you can reach out to us at support@pricelabs.co to enable this for your account.

Minimum and Maximum prices are not supported for Length of Stay (LOS) pricing in Smily at the moment. As a result, applying a high discount or premium through LOS pricing may cause the final rates to go below your default minimum or above your default maximum set at the listing level.

Verifying Length of Stay Pricing Adjustments in Smily
  1. Log in to your Smily account.
  2. Navigate Rentals → Property → Rates
  3. Under the Rate Rules section, you will see rules that says "Stay at least X number of days"
  4. You will also see that Midterm Pricing is activated

Troubleshooting Common Issues

Booking.com Monthly View When Connected Through Smily 

When a Booking.com listing is connected to any API partner—including RMS or PMS platforms—the monthly calendar view in Booking.com becomes unavailable. Users will only be able to access the list view and yearly view of the calendar. This is expected behavior on Booking.com’s side and applies universally to listings integrated via API. More details here.
