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: How does OKmarts handle unexpected price fluctuations or tariff updates after an order is placed?
A: Once a Proforma Invoice is issued and payment is confirmed, your pricing is legally locked. OKmarts absorbs any subsequent raw material price spikes, supplier price adjustments, or sudden export tariff increases, guaranteeing that the price you pay at checkout is final.
Q: How are long-term component supply risks handled if our factory relies heavily on a specific part sourced from your platform?
A: We offer supply chain buffering and safety stock agreements for industrial clients. By sharing your annual procurement forecast, we can pre-allocate inventory in our warehouses to guarantee a continuous, predictable supply and protect your production lines from market shortages.
