# Members and Contacts Invoicing

Invoices can be issued automatically or manually, depending on the customer. You can edit and cancel any invoice issued in Nexudus. You can also refund any paid invoice issued in Nexudus.

## Members Invoicing

Members are automatically invoiced based on the invoice dates defined in their contracts. Any pending bookings, products, or charges are automatically added to their invoices.

When you add a contract with a start date set to the current date or a date in the past, Nexudus automatically creates an invoice within 15 minutes. When members make purchases via the Members Portal, their purchases are added to their next invoice.

You also have the option to [manually invoice your members](/v3/docs/adding-invoices) for their purchases at any point.

## Contacts Invoicing

Contacts aren't invoiced for items added to their account from the Admin Panel until you manually issue an invoice for them. When contacts make purchases via the Members Portal, they're immediately invoiced for the purchased items.
