Purchase Records
This page allows you to view and create purchase orders and Purchase Records. You can then link these purchases to Products, Computers, or Printers from either the Purchase details or the details page of any of those items. Folders can be created to organize purchases further. You can also leverage Filters for complex search criteria, and Tags for organization and more complex meta grouping.

Like the Computers and Printers screens, each Purchase is shown as a line item which you can click to go to the details pages of that purchase. When you create a new Purchase, be sure to use the PO number to create the record. You can then add additional purchases to that same PO later. The PO# can not be changed by clicking the special edit button by that field.
Also note that bulk import of purchase records from CSV is possible using Import under the pull down ribbon in the upper right.
