What Syncs from Your PMS
Once your PMS is connected, OnSeason pulls in your property data automatically. Here's what comes across:
Property Details
Your property's name, description, property type (apartment, villa, house, etc.), and full address including location coordinates. This information appears on your booking engine exactly as you've set it up in your PMS.
Photos
All property images sync with their descriptions and are displayed in a gallery format on your booking engine. Guests see the same photos you've uploaded to your PMS.
Capacity
Maximum occupancy, bedroom count, and bathroom count — so guests know exactly what to expect when browsing your listings.
Pricing
Your starting price and currency are synced for display purposes. However, availability and exact pricing are always fetched live from your PMS whenever a guest searches. This ensures your booking engine always shows accurate dates and rates.
Availability and pricing are always fetched fresh from your PMS for every guest search. This ensures your booking engine never shows outdated dates or rates.
Amenities
Kitchen features, bedroom configurations, and property amenities are organised into categories so guests can easily find what they're looking for.
Ratings
If your PMS provides ratings data, the average score and review count sync to OnSeason. This helps build guest confidence when browsing your listings.
The sync process is straightforward:
Properties sync automatically after you connect your PMS — no manual action needed
Changes you make in your PMS are reflected in OnSeason — update your PMS and OnSeason mirrors the changes
If you need to change a property's name, description, or details, make the change in your PMS. OnSeason mirrors your PMS data — manual edits in OnSeason are not supported.
Managing Synced Listings
Your synced properties appear on the "My Properties" page in your dashboard. From here, you can:
Enable or disable individual listings for your booking engine
Disabled listings won't appear on your booking site, but they remain synced with your PMS
View listing details including photos, pricing, and availability at a glance
This gives you full control over which properties guests can see and book, without affecting your PMS setup.
Property Count and Billing
OnSeason counts your active self-owned properties for metered billing. The first 10 properties are included in your subscription, Properties 11–100 are billed at €3/property/month, and properties beyond 100 at €1/property/month.
See OnSeason Pricing Explained for details on how billing works with your property count.
