Step 1: In the "Reference persons" section of the matter, add all the persons you want to involve in the invoice.

Step 2: Assign the role "Invoice to" to all the people and save.

Step 3: (As of version 20.22.08) In the "Preferences" tab of the file, the name of the client and of the reference persons registered as "Bill to" are displayed in the "Payers" section. It is directly from this location that the user can configure the $ and/or % value of each.

Step 4: Proceed with the billing.

Step 5: In the "Payers" section of step 1 of the invoice creation wizard, the parties with the "Bill to" role and the client will be displayed as configured in the "Preferences" section of the matter.

It is of course possible to change the configuration at this stage if required for the current invoice.

Step 6: Continue with the billing process.

Result:

Note that each of the payers included on the invoice must have a percentage indicated.

It is also possible, if the user wishes, to display the distribution of payers on the invoice in order to detail the responsibility of each. (check box in the financial billing model)
