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.
You can attach files—such as a detailed time report, design drafts, or additional project information—to an invoice before sending it to your client. You can also attach an Expense Report, which will contain receipt images entered with your expenses.
