8. What factors should I consider regarding payment terms when sourcing pneumatic control valves?
   Payment terms can significantly impact your cash flow and procurement strategy. Discuss payment options with your supplier, such as upfront payments, letters of credit, or payment upon delivery. Be cautious of suppliers requesting full payment in advance, as this can increase financial risk. Evaluate the supplier’s payment terms against industry norms and your company’s financial policies.
