The procure-to-pay cycle
Every task a purchasing manager oversees (approving requisitions, reviewing purchase orders, resolving invoice disputes) sits somewhere in this cycle. If you can see the whole chain, you can spot where money and time leak out.
Supply chain and purchasing vocabulary
Suppliers, colleagues and executives use shorthand. Knowing the words lets you read contracts, quotes and reports without guessing, and sound credible from day one.
Excel fundamentals for purchasing
Excel is the buyer's everyday tool. Before you ever use an ERP, you will compare quotes, check invoices and summarize spend in spreadsheets. Clean, correct spreadsheets build trust.
The math of price, quantity and total cost
A buyer who picks the lowest unit price can still lose money. Freight, discounts, minimums and payment terms change the real cost. This math is how you prove which offer is truly cheapest.
Building a spend spreadsheet from public data
Spend analysis is the base of every sourcing decision. Doing it on public data gives you a real piece of work to show, before you have a job, and it proves you can combine the process knowledge, Excel and cost math from this stage.
