Hello gryphsol
Thanks for your post.
Regretfully, we don't support any invoices or packing slips third-party plugins.
For this reason, I'm afraid we cannot recommend any of them. Hope you understand.
Anyway, what you want would need custom development for any of the plugins you choose.
Unfortunately, this is out of the scope of our service, so I’d kindly suggest you find a developer to assist you with this customization if you need to achieve it.
Best regards,
Iryna
