VAT id is not imported from Virtuemart, as it is a custom field. a little bit of coding is necessary on the plugin in order to import custom fields.

Ok, I have modified

- /plugins/system/invoicemanager_virtuemart/invoicemanager_virtuemart.php
- /administrator/components/com_invoices/tables/invoice.php
- mysql table invoices_invoices

and now I can store the vatid and other fields in mysql.
Now vatid is correctly displayed in invoices, but the other fields? What other files do I need to change to make it work? I need to add a token that gets data from mysql table invoices_invoices.
Thanks in advantage.

well in that case you would also need to modify the /views/invoice/tmpl/default.php that is where the invoice is rendered.

Ok, online and pdf version gets new tokens, but not in admin invoice preview.

yes, for that you need to add the tokens into the VUE.js processor, in file /helpers/helpers.php

Added tokens in the array $search in /helpers/helpers.php file, without results

well if you only add them to the $search it will do nothing, you have also to replace them...

ok sorry for my basic php knowledge. Now it works... Thank you for help!
