CRM integration architecture

Most CRM integration failures are architecture failures that surface as data problems: two systems that both think they own the customer address, a connector nobody can see failing, a platform chosen before anyone listed what had to flow where.

Articles in this topic deal with the decisions that come before the code: where each record lives, how the CRM and the ERP divide the customer lifecycle, and which integration approach fits the volume, the risk and the team that will run it.

This topic answers

  • Which system should own each customer field?
  • Where does the CRM stop and the ERP start?
  • When is an integration platform enough, and when do you need custom code?
