Do you use Shipments?

What are you seeing when you try and invoice?

Hi 

Please check whether you have performed all steps mandatory in Order type connected to customer order

Regards

When you check “Quick Order Flow Handling”  what status is it in? Will it let you right click to process next step - create invoice?  Does your background jobs have any warnings /errors?   

Hi @simonfauci 

Please check whether that customer order line has ‘Invoiced Blocked’ turned ON. If so, you have to turn it OFF by editing the line.

Also check whether the ‘Confirm Deliveries’ option turned ON. If that’s the case, you need to first confirm the delivery from ‘Delivery Confirmation of Customer Orders’ page.
