Absolutely! Sign up is free and just takes a few minutes to fill out the required info (personal, company, banking). Once you're approved (takes about a day), you can go to work paying invoices. You can try it for as little or as long as you like. We even pay you for all the invoices you run through the system when you're trying it. If you decide you like it, just keep using it. If you don't like it, just stop using it. There's no monthly fee, so there's no difference between trials and being a full user. And there's no commitment on your part.
