You can try the Next Bill Date from the Saved Search:
Note: This will be the same with the saved search if the Sales Order has a Billing Schedule. If the Sales Order has no Billing Schedule, the default date is today’s date on the Invoice Sales Order page meanwhile the date shown on the Next Bill Date on the Saved Search will be the same as its transaction date.
Lastly, the ability to show all the Next Bill Dates on the Sales Order Saved Search based on the Billing Schedule is currently logged in as Enhancement 156014: Search/Reports> Advanced Billing/Billing Schedules > Be able to expose Next Bill Date and Next Bill Amount for sales orders in transaction search and reports, and there is no alternate solution for this at the moment.
