Follow the problem, then the product
If leads and follow-up disappear, begin with CRM requirements. If checkout, receipts and payment handling are the bottleneck, assess POS requirements. If purchasing, stock, fulfilment and financial records disagree across departments, assess an ERP or integrated operational workflow. More than one answer is possible.
Know the limits
A CRM does not automatically become a reliable stock ledger. A POS does not replace every finance or purchasing process. An ERP does not repair undefined roles or inaccurate master data. Product capabilities differ by edition, configuration and connected services.
- CRM: relationships, opportunities, activities and hand-offs
- POS: transaction capture, receipts, returns and payment workflows
- ERP: coordinated operational records across selected business functions
Example: enquiry to delivery
An illustrative flow is website enquiry → CRM qualification → accepted quotation → operational sales order → stock reservation → delivery → invoicing and payment reconciliation. Agree the event that moves the record, the system that owns it and the person responsible for exceptions. Do not send every record into every system.
Write an integration contract
For every connection, name the source and destination, shared identifier, required fields, sync direction, frequency and access scope. Define retries, duplicate prevention, failure alerts and reconciliation. Verify actual vendor interfaces and licenses before quoting an integration.
Pilot a complete transaction
Use representative sample data with permission. Test a normal sale, a cancellation, a return, duplicate messages and lost connectivity. Reconcile the resulting records with the responsible finance or operations owner. Expand only after the pilot can be explained and repeated.
Sources and editorial approach
