- Enter the Customer
- Enter the Item in the Items tab
- In the Billing Schedule column in the Items tab select the Billing Schedule for each Item that matches the date to be invoiced.
- Click Save
- Repeat Step 1 for all the items which are to be invoiced on a different date
- Create the Sales order and assign a billing schedule per line item
- Navigate to Lists > Accounting > Billing Schedules > New
