Yes, absolutely. If you're thinking of a low-volume, semi-manual system, you can simply generate a list of addresses, store them on a DB, and display them to customers for payment. Then send out your product/service once you verify payment has cleared on the Blockchain Explorer. That's a good, simple, low-tech way of taking care of things, as long as you carefully match addresses to customers and take care to securely store the wallet you used to generate the addresses. But assuming you can program, it's not hard to implement an automated payment processor, or to integrate a third-party API. Please don't be scared off by alarmists. As long as you are taking care not to store large sums of Bitcoins on your server, there's no problem. You can easily set a cron job to move the full balance off your wallet every minute to a cold, air-gapped, inaccessible, off-site wallet (Armory looks good for storage). As long as you're not distributing bitcoins (like exchanges have to do), you don't need to worry about keeping a large sum on the wallet you use for your app. Please feel free to contact me at the address on my profile if you have any questions (my user name is my real name).
