My spouse is an online clothing reseller since 2018. She sells on various online marketplaces like Poshmark, eBay and Facebook marketplace.

She always struggled to understand her numbers. Things like:

  • how much she is spending on products,
  • what is the value of her unsold inventory,
  • what are her expenses (ex: packaging, labels, printer ink, etc.),
  • what are her profits,
  • did she make money or did she lose money on certain transactions,
  • what is the total profit breakdown between all marketplaces,
  • how much profit did a clothing vendor made her, if any,
  • and so much more.

The web app runs on Rails 7, with Hotwire and PostgreSQL.
