The invoicing feature saves a lot of time. When the bot works, it's set-up-and-forget, when it cannot use it (for example with software that don't allow sending invoices by mail automatically), the manual upload is very quick too. Review collected by and hosted on G2.com.
Sometimes having hard limits on cards can be a blessing and a curse. I don't know if it's feasible, but allowing to update the max budget on card + retry the payment after a failed payment because of card budget would be a huge time saver. Review collected by and hosted on G2.com.
