Sales & getting paid
Products and services
Set up what you sell: services, non-inventory items and inventory you track.
Each product or service has a name, sales price, an income account (where its sales are recorded) and whether it's taxable.
Service and Non-inventory items just record income. Inventory items also track quantity on hand and cost — see Inventory.
Picking a product on an invoice fills in its description and rate; you can still change them on the line.
