PO Number during checkout

Standard installation 3.6. During checkout process step5 (payment information) there is an empty input field for PO Number? What is this for? Customer choose standard bank transfer (pre payment), so there is not any number/value to ask for. How can step 5 be disabled? It's totally confusing for customers.

It sounds like you're using the Purchase Order payment method as that's part of its standard functionality.  The Friendly Name of the plugin might have been changed to something different on your store.

Have a look in the admin area under: Configuration > Payment > Payment Methods where you can see the System Name for the payment method plugin to confirm whether this is the case.

Thank you for your reply. Yes, I' using Purchase Order payment method. Is there a better standard method/plugin for standard bank transfer? Because I couldn't find any other suitable method for this type of payment. So I need a new plugin for standard bank transfer?

The Check / Money Order plugin is basically the same as the purchase order method but doesn't have any fields for user input.  You could use that and change the friendly name to Bank Transfer.

The PO Number is often used by business customers - independent from the payment method selected.
Can this feature not be added during the normal checkout process ?

Just got bit by this one.

As previously mentioned (Feature Request - Purchase Order Number entry for any payment type), but then put on indefinite hold. PO Numbers are a requirement for most orders in business environments regardless of the choice of payment method. They're not a payment method (the payment method would be "Net Terms" or "Account Credit").

It might be confusing for consumers to see this field, but it is a must for businesses. Not only to capture it, but to display it in the order list, and to be able to search orders by it (so burying it in an XML field is probably a bad idea).

IMO, It is shortsighted for nopC to leave this to customization, or to consider it a low priority/impact feature (when it is a bare minimum requirement for a platform that could be used in a business environment - and having a well defined convention is important).

If we want to hide it for consumer sites, it could be store or role specific (ie, turn it on/off either for the whole store or only for a given role).

Purchase order number provided you directly to the customer in a manual agreement. You can use Cash On Delivery plugin to meet your purpose.
