I see so many bad reviews, but it looks like most of them are using Bill.com to invoice their customers. We only use it to pay our bills, and we have mostly loved the service. We've cut down the number of bills we receive on paper to just a couple each month, and the rest go directly into the Bill.com inbox. Attaching documentation is pretty straightforward, though I do wish they would make it easier to attach multiple documents from the same email - that should be seamless, but it's clunky. We love that we don't really have to think about whether our vendor is signed up with Bill.com or not. If they are, they get a direct deposit, if they're not they get a check. It's all the same on our end. It syncs well with QuickBooks Desktop, something which pretty much no other company has ever managed.
A few complaints: the import feature for long bills is persnickity - though most import features are, and this one is miles ahead of QuickBooks itself. It takes much longer than it should for people to actually get paid. Why does it take 5 days from "Pay" to "Epayment Received"? Paying faster is one of the reasons we switched and that hasn't really happened. And then there were a couple of mysterious duplicate bills that we can only track to their appearance on Bill.com. I'm not saying that Bill.com randomly duplicates old bills but... an extensive search provided no other explanation.
Thank you for the honest feedback, Rebecca. We’re constantly striving to improve our customers’ experience, and we’ll work hard to improve in the areas you mentioned.
