CRM vs ERP systems: what’s the difference?
Before you decide what to integrate first, it helps to understand how CRM and ERP systems operate.
CRM, or Customer Relationship Management, is focused on the front office; primarily sales, marketing, and customer service. It's typically used by sales reps, marketers, and support teams to manage leads, track pipelines, run campaigns, and handle customer cases. Popular CRM platforms include Salesforce, HubSpot, Microsoft Dynamics CRM, and Zoho.
ERP, or Enterprise Resource Planning, powers the back office. It’s used by finance teams, operations managers, and HR departments to manage core functions like order processing, invoicing, procurement, inventory management, and payroll. Leading ERP systems include SAP, Oracle NetSuite, Microsoft Dynamics 365, and Exact.
In short, a CRM helps you grow by optimizing how you attract and serve customers, while an ERP helps you scale by streamlining fulfillment, finance, and operations.
Why CRM and ERP integration matters
Disconnected systems cause broken processes, duplicate data, and frustration for your team and customers. Integrating CRM and ERP allows for:
- End-to-end visibility: From lead to cash, every step is tracked and streamlined.
- Fewer silos: Sales, finance, and ops can finally speak the same data language.
- Better customer experience: Accurate inventory, faster quotes, and seamless updates.
- Less manual work: Automate workflows like deal-to-invoice and order-to-fulfillment.
What to integrate first: CRM or ERP?
The answer depends on your current pain points. Here’s how to decide:
Start with integrating your CRM if:
- You’re focused on growth and customer acquisition
- Your sales and marketing teams work in disconnected tools
- You need better lead tracking, automation, and reporting
- Your ERP or back-office tools are stable for now
Example: A fast-growing D2C brand wants to accelerate pipeline growth and streamline marketing-to-sales handoffs.
Start with integrating your ERP if:
- You're struggling with fulfillment, finance, or inventory bottlenecks
- Manual processes are slowing down your operations
- You already use a reliable CRM
- Finance or procurement need clean, connected data
Example: A wholesale distributor handling thousands of SKUs wants to automate order processing and reduce errors in invoicing.
