The CRM-ERP Connection#

CRM and ERP are complementary systems that must work together. CRM manages customer relationships; ERP manages operational execution. The integration between them determines customer experience and operational efficiency.

Functional Boundaries#

CRM Scope#

Sales: - Lead management - Opportunity tracking - Quote generation - Sales forecasting

Marketing: - Campaign management - Lead generation - Customer segmentation

Service: - Case management - Customer support - Service level management

ERP Scope#

Order management: - Order processing - Inventory check - Fulfilment

Financials: - Invoicing - Credit management - Collections

Customer data: - Customer master - Transaction history - Account balance

Integration Architecture#

Customer Master#

Golden record: Single customer view.

Master ownership: - CRM owns: Contact information, relationships - ERP owns: Financial data, credit limits

Synchronisation: - Real-time: Critical data - Batch: Non-critical data

Data Flows#

CRM to ERP: - Customer data - Sales orders - Quotes to orders

ERP to CRM: - Customer financial data - Order status - Inventory availability - Invoice history

Transaction Flows#

Quote to order: - Quote in CRM - Converted to order - Order in ERP

Order to cash: - Order capture - Credit check - Fulfilment - Invoicing - Cash application

Integration Patterns#

Real-Time Integration#

Use cases: - Credit check - Inventory availability - Order status

Batch Integration#

Use cases: - Customer sync - Transaction history - Reporting data

Technology: - Scheduled jobs - File transfer

Event-Driven Integration#

Common Challenges#

Data Quality#

Duplicate customers: Multiple customer records.

Address validation: Consistent address format.

Contact ownership: Who manages contacts?

Process Alignment#

Quote-to-order: Handoff between sales and operations.

Credit management: Credit decision workflow.

Pricing: Consistent pricing across systems.

Change Management#

Sales team: Working in CRM, not ERP.

Operations: Working in ERP, not CRM.

Leadership: Visibility across both systems.

Deployment Options#

Integrated Suite#

Single vendor for both CRM and ERP.

Advantages: Native integration, single platform.

Disadvantages: May not be best-of-breed in either.

Examples: SAP (C/4HANA), Oracle (CX), Microsoft (D365).

Best-of-Breed#

Separate CRM and ERP systems.

Advantages: Best functionality in each area.

Disadvantages: Integration complexity, multiple vendors.

Examples: Salesforce + SAP, HubSpot + Oracle.

NZ/AU Considerations#

Local Requirements#

Address validation: NZ/AU address formats.

Phone numbers: Local number formats.

Privacy: Privacy Act requirements for customer data.

Integration Options#

iPaaS: Integration platform as a service.

Middleware: On-premise integration middleware.

Custom: Custom integration development.

Conclusion: Integration Is Essential#

CRM-ERP integration is not optional for organisations that want a complete customer view and efficient operations. Plan integration carefully and invest in ongoing maintenance.
