There are many ways to collect customer feedback for inventory forecasting, depending on your business model, goals, and resources. Surveys, reviews, feedback forms, social media, and email are some of the most common methods. Online or offline surveys can be used to ask customers about their satisfaction and preferences. Reviews can help to understand what customers like and dislike about products. Feedback forms can be used to collect product ratings, comments, complaints, or requests. Social media can be used to monitor and engage with customers while email campaigns and newsletters can be sent out to ask for feedback. Tools such as Google Forms, SurveyMonkey, Typeform, Feedbackify, Usabilla, Hotjar, Hootsuite, Buffer, Sprout Social, Mailchimp, Constant Contact or AWeber can be used to create and manage these forms of customer feedback.
