The wrong next product can cost far more than $29 in unpaid building, support work, and marketing to a second audience you did not need. What Should I Sell Next? helps you choose the next offer your current buyers and real capacity support. Map possible low-ticket, core, premium, and recurring products around one buyer and one connected result. Enter the price, cash cost, delivery time, expected volume, and value of your time. The planner shows contribution after labor, margin, monthly workload, capacity risk, and the launch order supported by your paid evidence. Why this can save or make you more than $29 Stop building four random products just because an online-business diagram says you need a ladder. See which possible offer could contribute money without consuming more delivery and support hours than you have. Use paid buyer behavior to decide whether the next move is a small core pilot, an adjacent low-ticket tool, a premium version, or no new tier yet. Create an optional order bump only when it solves an adjacent problem for the same buyer and remains clearly priced and unchecked. You receive a private offline browser tool with four editable offer roles, contribution and margin math, monthly workload scenarios, automatic loss and capacity warnings, an evidence-based launch order, respectful order-bump copy, local saving, JSON backup, CSV export, and printing. Immediate ZIP download. No account, login, installation, subscription, API key, or license key. Your business numbers stay in your browser on your device unless you choose to export them.
