User joins the site and creates an account. They get to use the tool and test it out as long as they like. If/when they decide it's worth purchasing a business account with more features, they do so via a link which sends them to the payment processor and includes their membership ID. The payment processor takes payment, verifies, and sends back a confirmation to a page I have setup which interacts with the implemented user system to make necessary changes to the appropriate account.
I've looked at Paypal's system, though Paypal has a bad reputation for unexplained account closures and being generally unreliable.
What other options are there for accepting online payments? I'm so clueless in this area I don't even know what to search for to find other payment systems.
Having said that, Paypal seems like a perfect fit for this. If you are anticipating over $1,000 a month, you also might consider a merchant account with an electronic payment gateway if you are in the United States or Canada.
Another 3PP you might check out is 2CO - they might be able to support you as welll
