Rep Buyer Tools
Free calculators, converters and checklists to help you buy smarter from Chinese marketplaces.
Which rep buyer tool should you use first?
Use the fee calculator before paying, the shoe and clothing size converters before choosing variants, and the QC checklist before approving warehouse photos. These tools support Litbuy and other buying-agent workflows where the final decision depends on item subtotal, verified service fees, exchange markup, parcel weight, seller size charts, batch-specific fit, and category-specific flaws. Start with cost when comparing agents, switch to sizing when selecting products, then use QC checks after the item reaches the warehouse. The tools reduce common ordering mistakes, but they do not replace live verification. Buyers should still confirm seller stock, current agent fees, coupon rules, shipping quotes, route restrictions, insurance options, parcel weight, seller return terms, packaging choices, support answers, saved screenshots, measurement evidence, and local import rules before shipping a haul.

Cost checks
Use the fee calculator before you top up or submit a parcel. Compare item subtotal, service fee, exchange markup, domestic shipping, packaging options, insurance, and international route quotes.
Sizing checks
Use centimeters and seller measurements as the final reference. US, UK, EU, CN, and JP labels are only shortcuts because replica batches can follow different lasts or garment blocks.
QC checks
Use the checklist after warehouse arrival. Confirm size tags, color, stitching, logos, measurements, packaging, and visible defects before international shipping makes returns harder.
Recommended tool workflow
Begin with the fee calculator when you are comparing agents or deciding whether a coupon actually saves money. A low service fee is useful only after payment fees, exchange spread, packaging, insurance and route quotes are included in the same estimate.
Use the converters before ordering, then use the QC checklist after warehouse arrival. This order prevents two expensive mistakes: selecting the wrong size before purchase and approving an item before the photos show the details needed for a safe shipment decision.
What to record before checkout
Keep a simple note for each order: product link, selected size, seller measurement chart, agent quote, exchange rate used, coupon code, estimated domestic shipping, and the QC checks you expect after warehouse arrival. This record makes it easier to compare Litbuy with another agent later because you can review the same inputs instead of relying on memory. It also helps support teams resolve sizing, missing photo, or fee questions faster when an order changes after payment. For repeat hauls, reuse the same checklist so you can spot changes in route price, volumetric weight, sizing risk, seller reliability, and QC issue frequency.
