Invoice Line Items
Add descriptions, quantities, and unit prices. Line totals, subtotal, VAT, and grand total are calculated automatically.
Line Item Structure
Each line item on an invoice has four fields: Description, Quantity, Unit Price, and Line Total. The Line Total is calculated automatically as Quantity multiplied by Unit Price. You must add at least one line item before you can save an invoice.
Invoice Totals
Below the line items the form shows a running totals section. Subtotal is the sum of all line totals. If VAT is enabled, a VAT (20%) row appears. The final Total is Subtotal plus VAT (if applicable).

Adding and Removing Lines
Use the Add line item button at the bottom of the line items section to add more rows. Each new line is appended with a default quantity of 1 and unit price of £0.00. To remove a line, click the trash icon at the end of that row. You cannot remove the last line — there must always be at least one.
