Gift certificates are a powerful tool for startups to attract new customers and increase sales. First, they provide initial engagement with potential customers who might not otherwise know about the startup. Customers who receive are more likely to try new products or services, which can lead to ongoing interest. Second, gift certificates can encourage repeat purchases if they offer additional bonuses or discounts on subsequent use. Additionally, certificates help startups manage cash flow effectively, as they are often purchased in advance, providing an immediate cash influx.
