Free AI finance tools for Amazon & Shopify sellers
Know what you actually keep.
Free tools that turn your seller reports into plain-English answers - what you made, what the platform took, and what to do next. Built by a 15-year FP&A lead, and your numbers never come to us - there's nothing to send us in the first place.
- Am I actually profitable - after every fee and cost?
- Where is my cash going, and when will it run out?
- Which products and channels truly make money?
- How much inventory should I actually buy?
