Who knew that receiving money online isn't as easy as getting handed cash in person? Turns out you'll need a little help to start taking legitimate payments using a PAYMENT GATEWAY that your customers know and trust. One of the best known worldwide is PayPal. I've been using it over a decade and it's recognized nearly everywhere; your customers will feel comfortable purchasing through PayPal since they're offered purchase protections and it's a company they know and trust. I've sold a LOT of stuff using PayPal and I can't say enough good things about them, but the truth is that there are other options out there that can add a little zing and pep to your sales processes. There are a LOT of alternatives, I wouldn't recommend spending too much time looking unless you're just after some specific feature you can't find with one of the main payment processors. You can also check out Amazon Payments for a quick and easy way to start taking payments online using a provider that is well know and trusted. The list goes on with providers I can recommend for various features, check them out and see if any can offer improvements to the ways you take money online. Square can help you take payments in person as well as online, and when it comes to plugging in your payment systems across the web other sites like Flint, AuthorizeNet, Wufoo (this is awesome, it can help you build beautiful functional forms that also accept payments), Braintree, Payoneer, Payza, Zapier (a very intersting site for linking your sales sites together), and 2CheckOut can give you backups and alternative gateways for taking payments. If you want to start working with digital currencies like BitCoin, checkout BitcoinPay, CoinBase, and BitPay.
