At first thanks for this software. In the Sales Invoices bottom of the table need “Customer Signature” & ‘seller Signature’. Please give suggestion.
You can use a custom field and fill it up with text or html formating.
Or you can use a custom theme.
If I remember well, there are already a few threads about this. You can use the Search button in the top right corner to find them.
I can not solve it, so please anyone can give that type of themes. where ‘customer signature’ and ‘seller signature’ already added
