You can set your base price using a static value, another channel's prices, or PriceLab's prices.
Go into a listing's settings by visiting the Settings page and clicking the small gear next to the listing.
Under "Base Price" there is a drop-down menu that allows you to choose "Set Amount," "Airbnb" or "VRBO," or "PriceLabs."
If you choose "Set Amount" you fill in a base price yourself.
If you choose "Airbnb," Host Tools will never set prices on Airbnb. It will grab prices from Airbnb and populate them to VRBO with any rules you have specified. Many people do this when using another service to set prices on Airbnb, but they want those prices slightly higher on VRBO to account for more host fees.
If you choose "VRBO," Host Tools will never set prices on VRBO. It will grab prices from VRBO and populate them to Airbnb with any rules you have specified.
If you choose "PriceLabs" Host Tools will pull prices from your PriceLabs account.
