Top Questions from OKmarts Buyers
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: Does OKmarts maintain a historical record of my purchases for future asset management or auditing?
A: Yes. Your corporate dashboard retains a permanent, secure repository of all past transactions, technical specifications, commercial invoices, and warranty dates. This allows your maintenance, repair, and operations (MRO) teams to instantly pull historical records for equipment auditing or one-click reordering of consumable parts.
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.
