Built in
The content management built into the Manager covers the pages an auction house actually needs: home, about, contact, location, terms and conditions, plus whatever else you add. Text, images and video are edited without touching code, and everything is translatable through the same translation system used for the auction interface itself.
Because the auction modules are part of the same site, bidders browse, register and bid without leaving your domain.
Or bring your own
Some customers already have a CMS and a marketing team who know it. That is a good reason not to move. We integrate with Umbraco and increasingly with Drupal, where the CMS owns the editorial content and the platform owns the auction, joined over the public API.
This is the same choice as everywhere else on the platform: use ours, or use yours and let the auction be a service behind it.
