Is it possible to disallow multiply orders of the same product (per client)

[milstanyu]

Is there an option in WHMCS to allow each product/subscription to be ordered only once for each client? In the other words, can I disallow clients to subscribe for the same product twice.

 

Why I am asking for it? Because usually client try to pay some subscription, then from some reason he don't pay, and invoice stay unpaid. After few days he get back and order the same product again.

 

This makes 2 invoices for the same product, one paid one unpaid. Then I must manually delete unpaid invoice.

 

I don't sell hosting. I sell software download subscriptions, so to subscribe twice per client is not needed (not logical).

No, I'd recommend against deleting unpaid invoices, cancelling the order should be enough.
