Fee prediction software that alerts Amazon sellers before profit-killing changes hit ($2M ARR)

Amazon fees change like the weather, but way less predictable. One day you're profitable, the next day a storage fee hike or fulfillment change tanks your margins and you don't find out until it's too late. FeeGuard is a predictive alert system that monitors Amazon's fee patterns, tracks your inventory, and warns you before changes wreck your bottom line. It sends real-time notifications when storage fees are about to spike, fulfillment costs shift, or referral fees change for your categories. You get 7-14 day advance warnings with exact dollar impacts on your products, plus automated suggestions to adjust pricing or move inventory. The tool integrates with Seller Central to pull your live data and uses pattern recognition to spot fee changes before Amazon announces them. You charge $199-$499 per month based on inventory size and alert frequency. The wedge is small-to-medium FBA sellers who can't afford to lose 20-30% profit margins to surprise fees, but the expansion is huge: automated repricing, inventory optimization, even predicting which products will become unprofitable before you source them. You grow through Facebook seller groups where people are constantly complaining about fees, YouTube channels that teach FBA strategies, and Reddit threads where sellers share horror stories about unexpected charges. Start with a simple dashboard that tracks your top 50 SKUs and sends Slack or email alerts when fee changes are detected. Add SMS notifications for urgent alerts, and build out historical fee analysis so sellers can see patterns over time. The market is 2.6 million active Amazon sellers who collectively hate fee surprises more than anything else in their business. At $300 average monthly subscription and 5,000+ customers, you're looking at $18M ARR serving people who desperately need this problem solved.
