Well it means a lot of work for companies like Channeladvisor. Channeladvisor already has the functionality to work with eBay immediate payment which bypasses the CA checkout and the sales are imported after the fact. I imagine this is going to be the norm for such systems after June 2011.

The issues I see at first glance is with shipping. eBay doesn’t let you be so bespoke with shipping methods as a checkout like Channeladvisor, eBay recently opened up to account for non mainland locations in the UK but I doubt they will get much more specific before next June. And how about promotional codes?

Third party checkout will be able to integrate no problem, but the sellers who have built their business on the extra flexibility of third party checkouts will have to edit their practises and how they price their shipping costs.

Fortunately, eBay has given everyone notice of this change – but as always you don’t really know the effect a change has on your business until you try it out :)
