Planning an ERP rollout?
Plan your system integration →Executive Context
As SMEs grow, they often adopt multiple systems—CRM for sales, e-commerce platforms for orders, payment gateways for transactions, and ERP for operations and finance.
Without proper integration, these systems operate in silos, leading to manual work, data inconsistencies, and delayed decision-making.
Effective integration ensures real-time data flow, process continuity, and a single source of truth across the business.
When to Use This Guide
Use this guide if:
- You are using CRM, e-commerce, or payment systems alongside ERP
- Data is manually transferred between systems
- Order processing involves multiple steps and tools
- You want to improve operational efficiency
Expected Outcomes
- Clear understanding of integration architecture
- Defined data flow across systems
- Reduced manual effort
- Improved accuracy and visibility
Integration Architecture Overview
In a well-designed setup:
- CRM manages leads and customer interactions
- E-commerce handles orders
- Payment systems process transactions
- ERP acts as the central system for operations and finance
👉 ERP becomes the system of record
Phase 1: Define Integration Scope
Identify what needs to be integrated.
Key Activities
- List all systems involved
- Identify key data entities (customers, orders, payments, inventory)
- Define integration points
Deliverables
- System landscape map
- Integration scope document
Gate Criteria (Phase Approval)
- Systems identified
- Data entities defined
- Integration scope agreed
Phase 2: Design Data Flow
Define how data moves between systems.
Key Flows
- Lead → CRM → ERP
- Order → E-commerce → ERP
- Payment → Payment system → ERP
- Inventory → ERP → E-commerce
Deliverables
- Data flow diagrams
- Integration logic
Gate Criteria (Design Approval)
- Data flows defined
- Ownership established
- Error handling considered
Phase 3: Implement and Validate Integration
Execute integration and test thoroughly.
Key Activities
- Configure APIs or connectors
- Test end-to-end scenarios
- Validate data accuracy
- Monitor integration performance
Deliverables
- Integration setup
- Test results
- Issue log
Gate Criteria (Go-Live Readiness)
- All flows validated
- Data accuracy confirmed
- Error handling in place
Integration Risk Register (Must Watch)
| Risk | Impact | Mitigation |
|---|---|---|
| Inconsistent data mapping | Errors across systems | Standardize data structures |
| Failed integrations | Process disruption | Implement monitoring |
| Manual overrides | Data mismatch | Automate workflows |
Common Integration Challenges
- Duplicate customer records
- Order mismatches between systems
- Payment reconciliation issues
- Inventory inaccuracies
Best Practices
- Keep ERP as the single source of truth
- Avoid duplicating business logic across systems
- Standardize master data
- Monitor integrations regularly
KPI Operating Model
| KPI | Review Owner | Cadence |
|---|---|---|
| Data synchronization accuracy | IT | Weekly |
| Order processing time | Operations | Weekly |
| Payment reconciliation time | Finance | Weekly |
Common Anti-Patterns
- Point-to-point integrations without structure
- Over-customizing integrations
- Ignoring data ownership
- Lack of monitoring
Recommended Artifacts
- Integration Architecture Diagram
- Data Mapping Document
- API Documentation
- Integration Monitoring Dashboard
Time to Value
- Week 2: Integration scope defined
- Week 4: Data flow designed
- Week 8: Integration implemented and tested
