Client and Vendor sequential numbering

Q:  Where can I find the setting that produces a pop-up window to choose Vendor or Client?  How do I use separate numbering sequences for Contact or Vendor? 

A:  ADMIN -> FIRM -> SETTINGS -> FILE.  Scroll down to the “Automatic File Numbering” section. 

Turn on the button “Use separate numbering sequences for clients, vendors, and other contact types”. 

Press the “Save” button. 

When entering a “NEW CONTACT” there will be a sub-screen that pops-up asking for confirmation of the type of Contact.  A different numbering sequence will be used for each type (Client, Vendor, Other).
