CRM systems support marketing, sales, and customer service functions by helping organizations better understand customer wants, ensure timely shipping, and collect payments sooner. They also allow all customer-facing employees to have access to the same customer information. CRM systems use market research and targeted marketing to learn about likely customer populations and regions, and concentrate marketing efforts on segments most likely to purchase products. Customer service systems provide automated 24/7 support to reduce costs. Salesforce automation uses software to increase sales productivity by streamlining processes like order processing and contract completion.
