The Opportunity

Problem

Solo ecommerce founders waste entire days manually syncing inventory across Shopify, Amazon, and Etsy, frequently causing overselling.

Solution

Founders receive a simple 'Recommended Action' list each morning instead of spending hours reconciling spreadsheets.

Target Audience
