    Top Questions from OKmarts Buyers

    • Q: What secure payment methods are supported for high-value international B2B transactions?

      A: To ensure transaction security and accommodate standard corporate purchasing workflows, we support secure international Telegraphic Transfers (T/T Wire), major corporate Credit Cards, PayPal, and Letter of Credit (L/C) frameworks for large-scale procurement contracts.

    • Q: What should I do if the specific part number is obsolete or discontinued by the manufacturer?

      A: Our technical engineering team specializes in obsolescence management. If a part is lifecycle-discontinued, we utilize our cross-reference database to recommend exact drop-in replacements or functionally equivalent alternatives, ensuring minimal redesign for your machinery.

    • Q: Does the OKmarts platform support Bill of Materials (BOM) uploading for rapid mass quoting?

      A: Yes. Procurement teams do not need to search for individual parts manually. You can upload an Excel/CSV file containing your complete Bill of Materials (BOM) with part numbers, quantities, and brands. Our automated processing engine, backed by data engineers, will generate a comprehensive consolidated quote within 24 hours.
