Envoi is where you send invoices and quotes, receive invoices and receipts from suppliers, and keep track of money coming in and going out. When you turn on accounting, Envoi keeps the books for you: what you do with your invoices is booked automatically. You create the account yourself and can send your first invoice straight away. You activate accounting when you are ready. ## First step Create an account, add a customer and send the invoice by email. ## Common tasks Look up the company in the Brønnøysund Register Centre and add the bank account and payment terms. Activate accounting and start the books with an opening balance. Mark the invoice as paid, in full or in part. Upload, take a photo or import from email. Saga reads the invoice. Send reminders and collection warnings, manually or automatically. Give others access, and decide what they can do.
