Dear support,

Some clients forget sometime to prepare the cash for the paiement, and when they are good clients i would like to be able to subtract it from they account even if it’s at 0. When i try to do that i get an error.
Going further in that idea, i would like to give the possibility for good clients to pay with there account even if empty (it’s like a line of credit that can be payed at the end of the month for example), it would be even better if we could limit that line of credit.

Regards,
