To create a new Customer, click the 
create button on the Customer grid page, accessed under the main menu sub-heading Setup / Customers, or in the same grid from within another form, (e.g. Supplier Contract).
Upon doing so, a Customer form window will appear. All yellow fields in the window are required to be able to save the form, while white fields are optional. Provide a unique Code that is used to identify the record, a Name for the Customer, and Type depicting the type of customer. After providing the required fields the user may optionally provide a Billing Address, Mailing Address, Phone, Alternate Phone, Fax, Payment Terms, and any Notes or File Attachments.
When you are finished, click the Save button to save your changes. For more information on the Customer’s workflow see Default Workflow Status
