Researching payment options
I got as far as FreshBooks in my research today. Google Checkout is being retired, with no plans by Google to replace it. It's easy to embed a PayPal button, but I'd like to include other options, like Visa Debit cards, and credit cards for those who use them. Likely FreshBooks is not a viable option, but I will call them tomorrow to see how it works and whether their service would fit my decidedly minimal needs.
