Can I use a 17th Avenue theme with the WordPress.com Business Plan?

Yes, you can! The new WordPress.com Business Plan allows themes and plugins.

However, we still recommend self-hosted WordPress.org as the best option for a few reasons:

• The WordPress.com dashboard is significantly different from the self-hosted WordPress dashboard. Our themes are designed first and foremost for self-hosted WordPress, and all of our theme documentation is written for self-hosted WordPress. If you use WordPress.com, you'll find many of our instructions will not match what you see in your WordPress.com dashboard.
• Self-hosted WordPress.org is considerably less expensive than the WordPress.com Business Plan. Shared hosting from Bluehost or SiteGround is as low as $3/month, versus $25/month for the Business Plan.
• With self-hosted WordPress.org, your site is yours and yours alone, and you can do whatever you want with it. You are not at the mercy of a company that can shut your site down!
