I haven't used the app to print or email invoices yet as my store is still not live- but I am impressed by the ease of customisation of the templates on the free plan. The ability to email PDF invoices is a real drawcard for this app over other invoicing apps.
Customising PDF Invoice and Auto delivery to customers are exactly what we aim to do. We made the order invoice app, simple and easy to use without much overheads.
We aim to continue doing this and your remark indeed made our day.
