Before sending your first productive invoice, contact your customers and let them know that you will start sending invoices to them by using Basware service.

Request e-invoice addresses or email addresses from your customers.

E-invoice addresses can also be searched in the Basware Portal Business Directory:

• Open the PDF e-Invoice for Sending service from Basware Portal/Services: https://portal.basware.com
• Click Search Customers to open the Search Customers tab.
• Use the Search to find your customers. Your customer's e-invoice address to which you can send PDF invoices can be found in the Company's e-invoice Address column.
• Write down your customer's e-invoice address.
• Add the e-invoice address to the invoice.

Please make sure that the recipients’ e-invoice address is in the invoice image with prefix "E:" The recommended location for the customer e-invoice address is in one of the customer address fields and it typically requires updating customer address details in the billing system.

An e-invoice address is a unique number allocated for e-invoice receivers. It is often derived from VAT, DUNS, or another company-unique code.

If a customer does not have e-invoice address available, use the email address instead.

You can also place a text in the layout of your paper invoices where you request your customers to provide their e-invoice address or email address for e-invoicing.
