Creating a sales invoice
Create a sales invoice with customer details, document settings, lines and payment information.
Updated on August 28, 2026
This wizard creates a sales invoice for the active administration. It is initially saved as a pro forma. You need an active Billnado licence, a customer, a trade name and a sales journal.
Step 1: Customer
Select the receiving Client. Billnado copies the VAT number and default address; the address fields are read-only here. Update the customer record first if required data is missing.
| Field | Meaning |
|---|---|
| Customer reference | The customer’s reference, such as a purchase-order number. |
| Project | Links the complete invoice to a customer project. It becomes available after selecting a customer. |
| Parameters | Extra key-value pairs for document content. Customer parameters are copied as a starting point and known keys are suggested. |
Step 2: Document
| Field | Meaning and default |
|---|---|
| Date | Invoice date; today by default. |
| Expiration date | Payment deadline, calculated from the customer’s payment terms or the administration default. |
| Comment | Customer-facing text on the document. |
| Enable customer portal | Makes the invoice available through a unique guest link; enabled by default. |
| Self-billing invoice | Indicates that the customer issued the invoice and adds a required PDF step. |
| Structured payment reference | Generates a structured reference and locks the reference field. Disable it to enter a normal Payment reference. |
| VAT rate | Default VAT treatment for new lines; the customer setting takes precedence over the administration setting. |
| Default account | Ledger account copied to lines that do not yet have one. |
| Trade name | Sender and company identity shown on the invoice. |
| Journal | Sales journal used for grouping and subsequent numbering. |
| Internal note | Internal information that is not intended as customer text. |
Step 3: Lines
An invoice has at least one line. Article identifies a product, service or combined article. Selecting an existing article may copy its price, unit and configured description. Quantity, Unit price and VAT rate drive the totals; editing an amount excluding or including VAT recalculates the related values.
Show extra fields reveals Base price, Discount, calculated VAT amount, Unit, Serial number, Warranty, a line-specific Project, Ledger account and Remark. Hide on PDF keeps the complete line internal, while Hide price on PDF shows it without a price. Use Add line, Up, Down and Delete to manage order and content; the last line cannot be deleted.
Self-billing PDF and saving
For a Self-billing invoice, select exactly one PDF received from the customer. The wizard cannot finish without it. For a normal invoice, Billnado generates the document after saving, so the PDF may appear shortly afterwards.
Choose Create sales invoice to save the pro forma and open its details. It remains editable until you finalise it.
