For CRM, a lot of longtime Sage customers are still running ACT!, which used to be a Sage product before Sage sold it off in 2013. If that's your setup, you're dealing with two separately-owned systems now, not one vendor's integrated suite, so expect to build or buy a specific bridge rather than finding a native option.
For e-commerce, pairing WooCommerce or Shopify with Sage 300 or Sage X3 doesn't have a simple, universal plug-and-play connector the way, say, Shopify and Xero do. Some middleware tools cover parts of this, usually orders and basic inventory, but matching your specific tax setup, SKU structure, or multi-warehouse logic typically takes custom work on top of whatever the middleware provides out of the box.
For payroll, ADP and Sage don't have one universal native connection either; it depends heavily on which Sage product and which ADP service you're running, and the realistic path is usually a scheduled export/import or a direct integration built against whichever side exposes usable data access.
