In short, no.
An invoice, by definition, is for goods or services to be paid for in the future. We don't offer the ability to purchase our products in advance and then pay the bill later. Every transaction is completed at the time of purchase, which produces a receipt for that sale, the same way you'd get a receipt when you purchase a product in a physical store.
Shopify, the platform we use for our sales, does not provide and cannot generate an invoice for a transaction that has already completed. Your receipt is sent to you at the time of purchase in the form of an order confirmation email and includes every bit of information we have available to us.
BEACN does not offer volume or commercial sales, which would be the type of transaction an invoice might be appropriate for.
