We’ve recently released a couple of handy features for Harvest’s invoicing component:
Default invoice values – under Invoices > Configure you can now specify your default tax rate, payment terms, and invoice notes.
Translation – you can translate and customize every single phrase on the invoice and also the invoice email to your client. Go to Invoices > Configure, stroll down to the bottom of the page, and click on “Translate labels and message”. Note that the translated phrases will show up on the invoice PDF only.
