Create a new customer or supplier

Open Settings, then Contacts, and click New contact.
Enter the name and address (street, postal code, city, country). You need the email address later to send invoices.
Choose whether the contact is a customer, a supplier or both, and save.
In the invoice editor you can also do it directly: type the name in the Customer field and choose Create new customer.
If a contact with the same name and postal code, the same VAT ID or the same IBAN already exists, the app reports a duplicate, says which of the three matched and points to the existing entry. Save anyway only when it really is another company; that is recorded.
A contact the agent creates in the chat is saved unconfirmed and marked Proposed, please confirm. Open Settings, then Contacts, and click Confirm; only then does it get its number, and an invoice for it cannot be finalized before.
After saving, the contact appears in the list under Settings, Contacts. Its own page with turnover and open invoices opens from the contact's form with Open full page (turnover, documents).
