How can I do that?

Hi,

How can I have similar services like the purchase/order page on vbulletin.com on my forum?? e.g https://www.vbulletin.com/order/

That requires custom coding. We do not provide official support for custom coding, but you can try asking for this kind of help over at the vB mod site: http://www.vbulletin.org/forum/
