There are several types of offer codes in Nitesoft.
When building an offer the rate can be either fixed price or relative price. Relative prices can be +-fixed amount or +-% amount from current BAR rate. Read more about the BAR rate here.
In 'Agreements & Offers' in the menu you find the following offer types:
Agreements -is an offer code that can be linked to a customer profile.
Promtions Rates -is and offer code where you can add a fixed price or relative discount to room categories and select which products to include in the offer.
Packages -is an offer where you select the total price for the package and then enter which room categories and/or extras that should be included in the package (it is simpler than Promotion rate, you can for instance not have different prices for different number of guests or room categories).
Extra packages -(Enabled if you use Conference module) it allow you to build a package of extras that consist of many extras.
Rate Options is not an offer code but a way to add different payment and booking conditions to an offercode. For example you can configure if an agreement should get an invoice if they book online or if a promotion rate should be non-refundable and prepaid.
In 'Units & Rates' in the menu you find the following items relating to offer creation:
Rate Plans -If you want to build a rate plan that you can reuse for many offeres. For example if you have the same prices for agreements with several customers.
