Coinbase has just recently launched it’s Coinbase Commerce merchant checkout feature that supports Bitcoin, Bitcoin Cash, Ethereum and Litecoin payments. This feature enables the merchants who sign up to accept the above mentioned currencies into one user-controlled wallet. Merchants can integrate the feature directly into their e-commerce platform and it also supports integration into Shopify! It comes with a QR code feature for easy customer payments, a countdown for payments and a payment validation feature.

There are a few alternatives currently to this feature and some of them accept a wide variety of altcoins already. To name a few: Coinpayments, Cryptonator, Spicepay

Coinbase has a disadvantage here because they seem to only offer altcoins currently which they also support on their main exchange and wallet service platform. An advantage could be that they already built up several years of trust with their clients and for the merchants or business sites that only plan to accept a few currencies they might be the better solution.
