"Invoice": This indicates the purpose of the commercial document and should be placed near the top of the page. Name of your business: Format in bold and place at the top of the page. Include your company logo for a branded look.
Product or service details: Specify Description, Quantity, Rate, Amount and Subtotal. The more details you include on the invoice, the better. This way, your client will know exactly what they are paying for upon receiving the invoice. Make sure that your client can understand every item, so that as soon as they receive the invoice, they can pay you instead of asking questions and delaying the process.
