Are you trying to add customer types in Order Time but you can not find the option?
If you can not find the option to add Customer Types in Order Time it is most likely because you are using QuickBooks Online. QuickBooks Online will not allow 3rd party programs (Order Time) to add Customer Types.
This does not mean you can not use Customer Types. This just means the method of adding them is slightly different. You will create the Customer Types in QuickBooks Online and they will sync into Order Time.
