How should e-commerce operations and procurement salaries be calculated?

Here's a summary that practitioners have put together for your reference. For e-commerce, aim to negotiate a commission on GMV (gross merchandise value), which is based on sales volume, not pure profit—a small percentage of net profit will leave you underpaid. For procurement roles, pull your procurement expenses from the past two years, calculate the ratio of procurement spend to sales revenue, and structure your salary as 3,500 RMB base plus 50% of the absolute year-over-year reduction in procurement costs, or 50% of the absolute improvement in the procurement-to-sales ratio. In other words, you earn half of your cost-reduction and efficiency gains.

Pure profit commissions? I'm not doing it.
