← All coursesTRACK B · COMMERCE FROM ZERO

Commerce, from zero

How retail and the supply chain really work, from the barcode on a pack of gum to forecasting, replenishment and AI. Each module has a real company story, one plain idea, a kitchen-table picture, a worked example with real numbers, a no-code exercise and a self-check.

$99 one-time

Modules 1, 2 and 20 are free: the barcode, how retail works, and where AI fits across the chain. The other 18 modules are in the full course. 21 of 25 modules available now, more added as they're finished. The four finance modules marked coming soon are held for a professional review.
