Bill a Customer for a one-time charge, service, or custom line item without tying it to a Subscription's regular billing cycle.
Creating an ad-hoc Invoice takes you from a blank Draft to an issued, payable Invoice in one pass.
To create an ad-hoc invoice
Open the Subscription you want to bill, navigate to the Invoices tab, then click Create New Invoice. The Invoice is created in Draft status with pre-populated Subscriber information.
Optionally, click the Pencil icon to edit contact information, billing or shipping addresses, memo, or payment instructions.
Click Edit Dates to set the Issue Date and Due Date, and select the Net Terms.
Add a line item: enter a Name, Quantity, and Unit Price, or optionally select a Product or Component from the Catalog so Advanced Billing calculates the price for you. Add an optional Date Range to represent the service period; if you leave it blank, it defaults to today (Now). Click Add Line Item to save it, then repeat to add more.
Optionally, add a discount: select an existing coupon from the Catalog, or enter an ad-hoc coupon manually. A Coupon with Coupon Restrictions can't be selected from the Catalog for an ad-hoc Invoice.
Choose a payment collection option: remittance, or Immediately process payment method on file. If you choose immediate processing and the payment fails, choose Roll back creation of invoice or Issue invoice as "Open". If issued as Open on an Automatic Subscription, Advanced Billing attempts collection again at the next renewal; you can also collect payment manually at any time.
Click Issue Invoice. The Invoice status changes to Open, and it becomes available for payment.

Once the Invoice is issued:
If Customer or Subscription details change after the Invoice is issued, see Update Customer Information on Invoices.
For what ad-hoc Invoices are, and the Close Date and tax rules that apply to them, see Understand Ad-Hoc Invoices.
