How does Salesforce integrate with ERP?

Salesforce-to-ERP integration (often called "lead-to-cash" integration) syncs customer records, quotes, opportunities, and orders from Salesforce into the ERP for fulfillment, invoicing, and revenue recognition. Native connectors exist for NetSuite (SuiteApp) and Dynamics 365. Integration avoids duplicate data entry, ensures sales and finance teams work from the same customer record.
