Here's an example:

Payment Terms: Net 30. Please make your payment within 30 days of receiving this invoice. We accept payments via bank transfer, credit card, and PayPal.

Thank you for your business. If you have any questions, please don't hesitate to contact us.

So, the next time you're preparing an invoice, remember: it's not just a bill; it's a statement about your business.
