Whilst there are four currencies (which, if set to the same currency, can be used as additional price lists if required) it is also possible to create further sub Price lists for each of the four main price schemes/currencies. These should not be confused with Price Schemes.
For instance, you may want to create Price Book for a specific customer, or you may offer special pricing to charitable organizations.
These Additional Price options must first be configured on the Extra Pricing Page before it can be updated here.
Once you have configured your pricing by selecting a price scheme and entering a price, you can then select these pricing structures in the header of the equipment list editor.
