OB10 invoicing?

[Mr Tea]

One of the larger customers of ours has been in touch to say that they are moving away from paper invoicing to electronic invoicing in order to save the world and that, if we are to continue to supply to them, we will have to pay to register with - and then for each invoice submitted to - OB10 Limited, who will then forward them on our client.

Anyone else had any experience of this, we're loathe to pay the (relatively) trivial amount to join this scheme - should we just charge the client extra until we have recouped our costs?

Thanks
