How Do I Change The Billing Date For A Customer? – Merchant Resources

For a single payment, create an On-Demand invoice, select the desired collection date, and remove the original invoice date from the subscription schedule to prevent double billing.
For an ongoing subscription, cancel the current subscription and set up a new one with the desired start date. Billing dates for ongoing subscriptions cannot be changed once the plan has started.
