Digital planners have become popular for organization and productivity, appealing to a wide range of audiences. Start by designing a planner using software like Canva or Adobe InDesign, creating templates that include calendars, goal-setting sheets, and to-do lists. You can sell these planners on platforms like Etsy or create your own website to reach a broader audience. Using social media platforms, particularly Pinterest and Instagram, to showcase your designs will help attract customers. Digital planners are a cost-effective product to produce, and the right designs can generate a steady income. Offering seasonal or niche-specific planners, like wedding planning or fitness tracking, can increase sales potential.
