Opinions on Bill.com?

I'm considering using Bill.com to invoice our clients for our snow plowing company next season.

We have around 400 clients at the moment and I'm hoping this would significantly simplify invoicing for us and our clients.

I'd love to hear any thoughts you all have about the service.

I've tried to use Quickbooks for invoicing in the past and it was a mess both for us and our clients. Bill.com looks significantly more intuitive so far, but I've only been messing with it and creating test invoices to make sure it works the way we need it to before I send any invoices to clients using the service.
