I like that this program allows me to set reminders without taking up too much of my time! It also helps keep track all at once so it's easy when reviewing what needs paid or not yet paying out in payments due date has passed as well how many days are left until payment goes through etc.. There isn't anything about invoice duck i dislike but maybe just because there aren’t any issues right now haha!! Just give them try if you haven‘ t already they have amazing customer service support which makes things easier than ever before. We use billerduck mainly since we need quick turn around times from our clients getting their bills ready within 1-2 business day after being submitted by us (we do accounting/payroll services).
