Invoice customization to production/shipping note

Hi, is there more detailed instructions how to customize invoice template?
Would like to create estimate and use one of the custom invoice as production order(pdf printout) and shipping note(pdf printout) and then invoice/estimate.

Is there a list of all possible usable $keyworks ($invoice.invoiceNumber…)?


If you click ‘Help’ on the invoice design page you’ll see the list of variables

I did got there, but what about “Item”, “Description”, “Quantity”?

Are you using v4 or v5?

The line item fields aren’t available as variable in v4

sorry online not self hosted.
how do I find out what version it is?

Ok, then you’re using v4
