Top Questions from OKmarts Buyers
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: Can OKmarts provide specialized industrial packaging for sea freight or long-term tropical storage?
A: Yes. For international shipping or extended warehouse storage in high-humidity regions, we offer upgraded industrial packaging options. This includes vacuum-sealed anti-static (ESD) barriers, desiccant packs, heavy-duty wooden crates, and shock-absorbent padding tailored to withstand harsh maritime transit conditions.
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.

Kastriot BiranjiExcelente servicio al cliente. Necesitábamos una pieza de inmediato, cuando llamé para consultar la fecha estimada de envío (el sitio decía entre 7 y 10 días), fueron maravillosos, retiraron la pieza y se estaban preparando para enviar mientras hablábamos. Compañía increíble, servicio al cliente increíble.Helpful?(0)(0)
