FAQ
Do I need a CDP for Customer 360?
Not necessarily. CDPs are one approach. You can build Customer 360 with CRM integrations, data warehouse, or all-in-one platforms. Choose based on your stack and resources.
How long does it take to implement?
Basic integration: 2-3 months. Full Customer 360: 6-12 months. Enterprise with legacy systems: 12-24 months. Start with high-value use cases.
What's the ROI?
Companies report 15-25% improvement in customer satisfaction, 10-20% increase in cross-sell, and 20-30% reduction in support costs. ROI depends on how you activate the data.
Can small businesses have Customer 360?
Yes. Modern tools make it accessible. All-in-one platforms like Dewx, HubSpot, and others provide unified views without enterprise budgets or engineering teams.
What's the difference between Customer 360 and CDP?
Customer 360 is the goal (unified view). CDP is one tool to achieve it. You can have Customer 360 without a CDP, and a CDP without achieving true 360 (if data isn't complete).
Want true Customer 360 without complexity? Dewx Portal unifies customer data from email, chat, calls, and CRM automatically—no integration project needed.
