Start with a written buying brief
Define the customer, target retail price, preferred design houses, frame shapes, lens colors, and opening order size before requesting a quote. A precise brief produces a useful shortlist; a broad request usually produces a long, hard-to-compare catalogue.
Compare offers at model level
A brand name alone is not enough. Match the model reference, colorway, frame measurement, included packaging, minimum order quantity, unit-price tier, and dispatch estimate. Record substitutions separately so a similar frame is never mistaken for the requested model.
Confirm documents and commercial terms
Before payment, ask the supplier to state the invoice entity, payment terms, order lead time, shipping basis, return conditions, and the documents supplied with the shipment. Requirements vary by destination and sales channel, so the buyer must confirm what applies to the intended market.
Use samples to validate the repeat-order standard
Inspect frame alignment, hinge movement, lens condition, markings, accessories, and packaging. Photograph the approved sample and keep the model reference with the inspection record. Future orders should be checked against that same standard.
Quick answers
What information should I send for a wholesale quote?
Send the models or brands of interest, destination country, estimated quantity, buyer type, and required delivery window. Add target shapes or price bands when the exact models are not yet selected.
Should I ask for one price or price tiers?
Ask for price tiers tied to quantities. A quote should make clear whether the MOQ applies per model, per colorway, per brand, or across the order.
How do I compare two supplier catalogues?
Normalize both catalogues into the same fields: model, colorway, size, quantity, unit price, packaging, lead time, shipping basis, and after-sales terms.
