Sales invoice saying paid in full

Using same as always, now, as soon as I make a sales invoice it says instantly paid in full.
Nothing changed.

There are two possibilities:

  1. You are using a very old version of the program that allowed sales invoices to be created without designating a customer. In such a case, the invoice shows paid in full immediately.

  2. You had a credit, deposit, or advance for the customer that Manager applied automatically.

Go to the Sales Invoices tab and click on the blue Balance due figure for the sales invoice in question. Post a screen shot of the list of transactions. This will reveal why it is paid in full.

Ok apparently I had a payment or receipt in twice for 596.86 same invoice. That caused a credit for 596.86 every time I generated a new invoice for that customer. Thank You.
