Product Pricing Based on Business Costs - Support the development of product/service quotations by calculating and incorporating business costs (e.g., COGS, logistics, labor, overhead, third-party fees). - Work with internal teams (procurement, operations, finance) to obtain accurate cost inputs. - Apply approved markup/margin policies to generate customer-facing price proposals. - Maintain a pricing log to track quotation history, cost changes, and margin performance. 5. Document & Process Management - Maintain a centralized contract and pricing database. - Track key commercial dates (renewals, price adjustment windows, termination notice periods, payment due dates). - Support internal approval workflows and prepare commercial summary sheets for decision-makers. 6.
