Within the extenion it is possible to use differrent invoice numbers: use order ID, use ordernumber and own numbering.

At the moment I am using an extension "Custom Order, Invoice and Customer Number plugin" which allows me to set my own ordernumbering.

What I like to have within the VM invoice extenion is that I can use this (own) ordernumber and using a prefix.

I didn't tried yet, but I think I can use the ordernumber I have created with this other extenion as invoicenumber, but I can't using the prefix field. This prefix field only works it I use "Own numbering" and not "VM order number".

Hello,

please, see the screenshots (available settings in VM Invoice)

Thanks for the screenshot, but this is not what I mean.

In this setting, I use 'Use ordernumber VM'. What I like to have is using a prefix with that, so the invoice number is the same as the ordernumber, except it has a prefix.

(The VM ordernumber is also my own numbering, using another extension to change that. Maybe that caused the misunderstanding between)
