You can create multiple price lists in Akti, as discussed here.
In the general overview of your price lists you can also define which price list is the "default price list". When you create a new account in the CRM, this account will be by default in this price list and will see the prices associated with it on quotes, sales orders, invoices etc.
To set this up go to 
Catalog Settings, open the "Price Lists" menu and select one of the lists as Default.
