Line item

A line item is a single row on an invoice representing one good or service, with a description, a quantity, a unit price, and the resulting line total; the sum of every line-item total is the invoice subtotal.

Applies in: Global

Line items are how an invoice gets specific. A good line item answers three questions the buyer's AP team would otherwise have to ask: what was supplied, how much of it, and at what unit price. The line total falls out of that, the subtotal falls out of the lines together, and the buyer can match the invoice against their purchase order without ambiguity.

The right level of granularity depends on the audience. A corporate buyer with a strict PO match wants each PO line reproduced on the invoice, even if it makes the invoice longer. A small buyer who just wants to pay does not need every billable hour separately listed. The default is: enough granularity that the buyer can match it to whatever they authorised, no more.

Line-level tax and line-level discounts are common in mature invoicing. Different items can have different VAT or GST rates (a UK invoice mixing standard-rate 20% goods and zero-rated books, for example) and per-line discounts can apply where some items are promotional and others are not. The total reconciliation gets cleaner when each line carries its own rate rather than a single invoice-level rate fudged across mixed content.

Common questions about Line item

How granular should line items be?

Enough that the buyer can match the invoice to whatever they authorised (the PO, the quote, the contract). Less than that and you set up a dispute. Much more than that and you produce noise. For a corporate buyer with line-level POs, reproduce the PO lines on the invoice. For a small buyer with a flat-rate engagement, one or two lines is fine.

Can different line items have different tax rates?

Yes, and they should when the underlying goods or services attract different rates. A UK invoice mixing 20% standard-rate consultancy and zero-rated printed books should show 20% on the consultancy lines and 0% on the books, with the tax breakdown carried through to the subtotal. JupiterInvoice supports per-line tax rates by default.

How do per-line discounts work?

A per-line discount reduces the unit price or the line total for one specific line, leaving others untouched. The line then carries forward its discounted total into the subtotal. This is useful when one item is promotional or matched to a specific contract clause, while other lines are full-price. Invoice-level discounts (a flat percentage off the whole subtotal) are the alternative pattern.
