I write this in the hope it will be taken constructively: I think you desperately need a good information architect and copywriter to redo your home page, tour, etc.
I have spent much of the past two days looking at various options for recurring billing and related automation for a start-up. It sounds like your service ought to be of interest to me, right now.
Unfortunately, I have absolutely no idea after scanning your home page and tour page what your target market is. Are you aimed at invoicing for freelancers/agencies with a few repeat clients? Monthly billing for end users of subscription web services?
You have written a lot (probably far too much) on your home page and tour page, but without enough detail about what your service actually does to decide whether it's worth investigating further. For example, you mention tax, but not whether you automatically handle VAT based on location (without which you aren't going to get very far here in Europe). You mention payment collection and credit cards, but without a clear statement of your level of PCI DSS compliance and whether clients need to handle any card data on their own systems to use your service (without which you probably aren't going to get very far at all).
You aren't short of buzzwords and transparent marketing drivel, though, and there are a few silly spelling errors and the like as well. That all paints a very unprofessional picture given that you're asking clients to trust you with vital financial matters.
For what it's worth, I did spend about 15 minutes looking over your site before writing this post, partly to try to be honest but constructive in the criticism, and partly out of genuine interest. In roughly the same amount of time looking at the web site of another business this morning, I had confirmed that they offered broadly the service the start-up was looking for, identified most of the details about how the start-up's pricing plans could be implemented using their system, identified a few specific details to ask about and an e-mail address where the questions could be sent if and when the start-up was ready to explore more deeply, worked out approximately what the monthly costs would be for adopting the service, and begun exploring the customisations and APIs to see whether they could address any of those questions I mentioned before.
On a more constructive note, your site does look attractive, and I expect most of the bad impression it made on me really could be overcome quite quickly with a bit of professional help to structure the content, so that the important details come across and the general feel is more professional service and less budget store TV ad.
