Marketo provides easy-to-use, powerful marketing software. By integrating Marketo with CRM systems you remove the need to manually rekey customer and lead data, improve data accuracy, and drive commercial performance.
Many organizations will update customer and prospect information in CRM or ERP systems. A marketing team that is using Marketo will want to have updates reflected in Marketo so they have the most accurate system of record to use in their marketing campaigns. Similarly, any leads generated within Marketo need to be shared with the CRM / ERP system.
