Hi David

For Sage 200 in the UK, the recommended integration is provided via Qnect 200.  This is the integration provided by Qmulus.  You can find details of this integration on the Sage Marketplace.  Qnect 200 | SAGE UK Marketplace

You can see the support status for Sage 200 here:  qnect 200 supported version matrix.pdf (qmulus-solutions.com)

Just to add to Sage CRM Qnect 200 does support Sage 200 Standard although the feature set is slightly different based on the functionality differences between Sage 200 Pro and Standard. However, in the majority of cases the features are the same.
