Top Questions from OKmarts Buyers
Q: Can my organization create a dedicated corporate account with multi-user permissions for different procurement roles?
A: Yes. Our platform supports corporate account provisioning. A master account can be set up for a Procurement Director, with sub-accounts granted to field engineers (for creating technical carts) and purchasing agents (for executing payments), streamlining internal corporate approval workflows.
Q: Can OKmarts assist in verifying technical compatibility before I place a high-value order?
A: Yes. Buyers can upload existing equipment nameplates, system schematics, or parameter requirements. Our applications engineers will cross-verify physical dimensions, electrical ratings, and communication protocols (e.g., Profinet, EtherCAT) before finalizing the order.
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.
