Purchase Orders - Is it possible to change the font size in the message to supplier box and the memo box?

Hello michelle34,

You will need to edit the font size of these boxes on the Master invoice template - all transactions that are not invoices automatically pull from the master template. Go to the cog wheel > custom form styles and select edit on the template marked as Master. Go to Content and select the bottom section of the invoice to edit the font size of the memo box.

Thanks,

Talia
