Badr Alghamdi

I work in supply chain and procurement, on the buying side of industrial supply chains, and I live in Riyadh.

I source across supplier markets, negotiate with factories and freight forwarders, then run the schedules, specifications and payment terms that were agreed months earlier.

Each page here takes one mechanism, lets you move it, and shows the arithmetic underneath, with a section on what the model does not do.

The site is free.

The views on this site are my own. The site does not provide professional, legal or financial advice.

The reliable way to reach me is LinkedIn. A specific case is the most useful thing to send: a lead time that turned out to be a distribution, a document chain tighter than the plan admitted, a number somebody has to defend at the start of the week.
