Shopify Checkout Pay Later

Hi I can see in the shopify admin portal, that when i am keying on a test order there is a tick box for payment due later. This allows me to create the order which i can then export into our ERP system, this is needed as we have payment terms with customers and what to make use of these.

My question is, on the shopify checkout, currently i have an option to pay using paypal but that is it, is there anyway to add this payment due later functionality into the checkout so a customer can just select that, confirm the order and then have payments handled through invoices from our ERP system which is our current process?

Except that you are Shopify Plus, you have to use 3rd party apps. I found an app called BSS: B2B & Wholesale Solution, which has a lot of b2b features, including Net Term (buy now, pay later)
