A: We partner with premier global express couriers, including DHL, FedEx, and UPS, to provide expedited international air freight. Urgent orders are processed with priority handling at our warehouses to ensure the shortest possible transit time to your facility.
Q: Can OKmarts issue formalized, compliant proforma invoices and commercial invoices tailored for corporate accounting?
A: Absolutely. Our automated billing system generates itemized Proforma Invoices (PI) and Commercial Invoices containing corporate tax IDs, purchase order (PO) numbers, and explicit company details necessary to satisfy international corporate accounting and auditing standards.
Q: Are there any hidden fees, handling charges, or unexpected export tariffs added to the final invoice?
A: Our pricing is transparent. Line items for product costs and shipping fees are explicitly detailed at checkout. Local import duties, VAT, or regional consumption taxes are typically the responsibility of the importer of record unless a DDP (Delivered Duty Paid) arrangement is pre-negotiated.
