One Step Checkouts are all the rage with shopping carts at the moment. The default Magento checkout process can be a bit long-winded.
The rather appropriately named “One Step Checkout” is, as you might guess, a one step checkout add on for Magento. The standard version is €190 (it’ll be good enough for most) and the enterprise at €590. On a shop of any size, even a small increase in conversion rate will pay that back quickly and many times over.
The only caution I have is if at all possible, do an A/B split test on the checkout. While one page checkouts are all the rage with shop owners, my own tests and tests of others I’ve worked with has shown that they sometimes decrease, not increase conversions. However, every site is different, so experiment away!
