Ibrahim Ölmez is the founder of nouz. He has spent the past seven years in ecommerce, building, scaling and selling several ecommerce brands.
From spreadsheets to nouz
For all of those years the profit calculations ran in spreadsheets, until they grew too complex to trust. He founded nouz in Vienna to replace them with a daily profit and loss statement for Shopify stores, after every cost.
He builds the P&L engine behind nouz and writes the nouz blog, so the rule an article explains is the rule the product runs.
The story of nouz itself is on the About page, and how every number in these articles is computed is set out in the methodology.
