The initial onboarding phase is critical in shaping a customer's experience and expectations. Investing time and resources in the first 24 to 72 hours post-sale enhances customer confidence and reduces anxiety. Establishing clear communication regarding schedules, introductions, and support helps newcomers feel welcome and informed. This proactive engagement can significantly boost customer retention and lead to increased future purchases. If a business struggles with growth despite adequate advertising, the issue may lie in the onboarding process rather than the marketing efforts.
