Line items are the heart of an invoice — they're the individual charges your customer pays for. In Cornerspot you build them in the Line items section of the invoice form: add a product from your catalog or a custom one-off charge, set the quantity and unit price, and let the line totals roll up into the invoice Subtotal. This guide shows you how.
How to add line items to an invoice in Cornerspot
You build line items while you're creating or editing a draft invoice. Each line has a description, a quantity, and a unit price; the line total and the invoice Subtotal update automatically as you go. You can add as many lines as you need and remove any you don't.
1. Find the Line items section
On a new or draft invoice, scroll to the Line items section. When it's empty it prompts you to “Add a product or a custom line to begin.” Click Add line item to start your first row.

2. Choose a product or a custom line
Each row starts in Select Product mode, where you can pick an item from your product catalog (you can even create a new product inline, without leaving the form). To bill a one-off charge that isn't in your catalog, switch the row to Custom Item and type its name.

3. Set the quantity and unit price
Give the line a clear description, then enter the Quantity and Unit price. Cornerspot multiplies them to show the line Total, which updates the moment you change a value.

4. Add more lines — they roll up into the Subtotal
Click Add line item again for each additional charge. Every line's total adds into the invoice Subtotal shown at the bottom of the section, so you always see the running total as you build the invoice.

5. Remove a line you don't need
To drop a line, click the × at the end of its row. The line disappears and the Subtotal recalculates immediately. You can also reorder lines by dragging the handle on the left of each row.

6. Review your line items
With your lines in place, the Subtotal reflects exactly what you're charging. From here you'd set your terms and save the draft — and you can come back to adjust the line items any time the invoice is still a Draft.

Per-line taxes and discounts
Each line can carry its own taxes and discounts. Expand the Taxes & discounts control on a row to attach a saved tax rate or discount that applies just to that line. Line-level taxes and discounts stack with any invoice-level ones into the invoice's Discount, Tax, and Total — see the guide on applying taxes and discounts for the full picture.
Good to know
- Line items are draft-only. Like all invoice content, they can only be changed while the invoice is in Draft. Once you finalize, the invoice is locked — to fix a finalized invoice you void it and create a new draft.
- Create products inline. If a charge should become a reusable catalog item, create the product right from the line-item picker so you don't have to leave the form.
- The Subtotal is pre-tax, pre-discount. It's the sum of your line totals; taxes and discounts are applied on top in the totals band.
