CRM system

CRM System: architecture, integrations, and data control

In short

A CRM system is the infrastructure for a company's commercial data: partners, opportunities, quotes, and orders. When choosing, the priority is not the demo features, but the data model, available integrations, and who owns the data at the end of the contract.

Who searches for this and why

The term 'CRM system' is most often used by those thinking in terms of infrastructure - IT Managers, CTOs, or CFOs. They don't ask about 'button features' but about integration, data residency, and exit strategy.

What "CRM System"

A CRM system is the framework consisting of the commercial database, process logic (stages, approvals, pricing rules), and the interfaces through which it communicates with other corporate applications - ERP, email, telephony, B2B portals, and reporting systems.

The 5 architectural questions that decide long-term success

Most demos look similar. The differences emerge in year two, when you need to change a workflow or extract your data.

  • Is there a documented API for all entities, or just for those shown in the demo?
  • Is your data isolated on its own tenant or stored in a shared, multi-tenant database?
  • Can you perform a full export in a structured format, without fees or support tickets?
  • How are upgrades handled: automatically with a risk of regression, or in a controlled environment?
  • What happens to your integrations during a major ERP version upgrade?

ERP Integration: three models and their associated risks

How the CRM system connects to your ERP determines your maintenance costs for the next five years.

  • File-based import/export - cheap to start, but fragile, delayed, and lacks error reconciliation.
  • Third-party middleware - flexible, but adds another vendor and an extra point of failure.
  • Native bidirectional connector - the CRMconnect approach, featuring entity mapping and automated error retries.

The CRMconnect architectural approach

CRMconnect runs in single-tenant pods: every client has their own instance and database, with auto-scaling on Kubernetes. ERP connectors are native, and modules like OMS, WMS, EDIconnect, and SupplySync use the same data model, eliminating internal synchronisation maintenance.

  • Complete tenant isolation with no shared data between clients.
  • Native connectors for major international ERPs like SAP Business One, Microsoft Dynamics 365, and Sage.
  • Full data export available at any time in structured formats.
