Addon for previous invoice created as separate invoice

[eger]

I had this bug once before and thought it was resolved. I will try to recreate my steps as close as possible.

 

What is happening is that I manually create an order for a product that has an Addon with an amount of $50 and a Billing Cycle set to 'One Time'. I chose NOT to generate the invoice. I then checked everything and it looked OK. I accepted the order. Then I manually used the Generate Invoices button. Invoice was generated and sent to client which contained the product first month prorated price and the $50 addon one time fee.

 

The next morning when my cron runs to generate invoices it generated another invoice for the Addon (only $50). Did I do something wrong here?

 

I don't know why under any circumstance an invoice should be generated again for a line item that was in another invoice already.

 

Bug?

We had a similar problem with an addon being billed in addition to an invoice that already contained the item. This occurred with an existing invoice after we upgraded to V3.4. We attributed it to the billing date range changing in the new version though:

I read your thread. Though I'm not quite sure how it's date related. Can you explain why you think it's date related at your post?

 

In either case... I didn't modify any date except the products pro rata date so it lines up with existing due dates. Not sure how this could affect it though.

 

One thing I DO notice is that the due date and next invoice date are the same and are the day that you create the order.

Hi,

 

The invoicing of a one time addon twice has been identified and corrected as a bug a few days ago. The issue was that once a one time invoice was created, the next due date is set to 0 but then an invoice is created for that date on the next run. Only occured when continuous invoice generation is enabled so wasn't caught sooner.
