My small business has a mix of B2B and B2C clients. When a new client signs up we always ask them what their preferred payment method is. Most people reply with “credit card” or ‘bank transfer’. But on several occasions now clients have replied with “invoice”.
What on earth are they thinking? An invoice is a document detailing what they are being billed for. 100% of our clients get an invoice, but it is not a payment method.
Why do people think that an invoice is a payment method??
Large established companies put your approved purchase order into the hopper for processing. Nothing to do with your client who managed to get it signed off.
Call the company and speak to the department handling accounts payable and get more info.
