Your pricing [1] is simple, but I'm a bit surprised that there isn't something that scales with volume. For example, I know banks and retailers commonly offer 0% interest over 10 months for direct customers, but that's with the hope of additional related business. Are you that "more business"? (it seems like maybe? Since some jobs are not interest free and the basic plan is also with interest).
Alternatively, what does "9% subsidy instead of 11% on successful finance applications" means? (I was put off by the intercom chat widget wanting me to provide an email to watch your demo video. Sorry. I'm also not a potential customer). Is that where the risk premium gets included?
I also get to repeat the patio11 meme: charge more. For 45 pounds a month at the top end, you've probably returned a small fortune to the business owner. Even just handling the quoting and receipt of payment part is a big deal! (Here in San Francisco, it can be hard to get an invoice from a contractor and even send them payment; we've had to follow up for months!). Tossing in Financing and support for cards (and do you mean "debit" or also "credit" cards; I know you're UK based, so the defaults are probably obvious to your audience, but I figured I'd ask).
Either way, sounds like a big win for small shops!
P.S. There's also a "Downlaod" typo in the first pricing column.
