For starters, you don't ever have to personally send an invoice to your clients. There is literally nothing for you to do.
The invoices for work done on Malt are issued automatically at project completion and are addressed directly to your client. They are pre-filled with the contact details—and other legally required information—that both you and your client input into Malt when creating your accounts.
Sometimes, your client may request for invoices to be sent to a company's accounting department instead. No problem at all—we can help with that.
