Cookbay product margin and bundle pricing model

Context. Product revenue alone did not show whether individual items or bundles made commercial sense after platform and fulfilment charges.

What I did. I built a worksheet to compare single-item and bundle economics using selling price, product cost, platform fees, fulfilment charges and other stated assumptions. The model highlights contribution margin and the sensitivity of results to fees and pricing choices.

Deliverable. A reusable margin and bundle-pricing worksheet with assumptions documented, so a seller can test alternatives before changing a listing. This work describes my own operation and does not imply a verified sales uplift.
