Why CRM and ERP Must Talk to Each Other
When the sales team works in CRM and finance works in ERP without the systems being connected, data silos emerge. Information must be entered manually multiple times, and the risk of errors increases. Integration between CRM and ERP provides a single source of truth — from quote to invoice.
A good integration means salespeople can see the customer's payment history, open invoices and credit limits directly in CRM. At the same time, the finance department automatically receives updated information about new deals and changes in customer relationships.
When Should You Integrate First?
If your ERP system works well and meets business needs, but the CRM solution is new or being rolled out, it is often smartest to integrate first. You get immediate value from both systems without taking the risk of changing both at once.
Integrating first also gives you the opportunity to map data quality between systems. You quickly see where there are gaps, duplicates or inconsistencies — valuable insight before any ERP upgrade.
When Should You Upgrade ERP First?
If the ERP system is approaching end of life, lacks critical functionality or does not support modern integration standards, upgrading should be prioritised. Integrating with an outdated system provides short-term gain but can become costly when the ERP must be replaced anyway.
An ERP upgrade often provides new APIs and integration capabilities that make connecting to CRM easier and more robust. Microsoft Dynamics 365 Business Central or Finance & Operations, for example, have built-in connectors to Dynamics 365 Sales.
How to Avoid Costly Missteps
The most common mistake is underestimating the complexity of data migration and integration. Start with a thorough mapping of data flows between systems. Clearly define which data should be owned by CRM and which by ERP.
Another common mistake is trying to do everything at once. A phased approach reduces risk and makes it easier to handle challenges along the way. Start with the most important data points — for example customer and product data — before expanding the integration.
