In Hubspot CRM, if I am sent a bill from a vendor, at the top it shows how much I owe from ALL open invoices and there is a convenient option to click and pay them all at once. I would benefit from this very much.
I know it is planned to have the clients be able to pay multiple invoices at much (which I need) but also the option to always have it show when they view any of their invoices online would be phenomenal.
