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.
Invoice Date: The issue date for the invoice. Pro tip: Getting your invoice out in a timely manner can help you improve cash flow and get paid faster. Bill your customer using the mobile invoicing app, right after you finish the job.
