As far as I know, when you have project transactions and Work Order Transactions there is not a way to send the customer a single invoice.  You have to invoice the project transactions using a project invoice and you have to invoice the work order transactions through a Customer Order.  Am I right on this?

Is there a way to combine both into a single invoice?

Our customer is concerned about the acceptability of receiving multiple invoices.

Any ideas might be helpful.

Thank you.
