Your rates live in Sites & Pricing. Go to Revenue Management → Sites & Pricing; the page opens on the Pricing tab. (This page used to be called the Rate Editor.)
How pricing is organized:
Site plan: a group of sites you sell the same way, like "RV Sites", "Cabins" or "Tent Sites". It holds the photos, policies and tax settings the whole group shares.
Pricing tier: a rate inside a plan, like "Premium Pull-Through" or "Standard Back-In". This is what your guests book.
Price period: the dates and the prices: nightly by day of the week, weekly or monthly. A tier can have several, one per season.
Assigned sites: the sites sold under that tier. A site with no tier can't be booked.
At the top of the Pricing tab you see four counters: site plans, pricing tiers, sites with a rate and sites without one.
To create a site plan, press + New Site Plan. Once your plan and tier are ready, add your sites in the Sites tab (+ Add Site, one site or up to 50 at once) and assign them to the tier with Assign Sites. For the full guide, see Sites & Pricing.
