Yajuzhen Cloud Phone: Support Amazon Multi-Site Operations for Cross-Border E-Commerce Brother Wang, who runs multiple Amazon sites, used to be troubled by "operation environment" issues. He managed three sites in the US, Germany, and Japan simultaneously, and switched logins using the same WiFi for convenience. As a result, the German site suddenly received an audit notice requiring "proof of independent operation". It took half a month just to supplement the materials, which not only delayed the launch of new products but also caused a loss of over $30,000 in a single month due to the decline in store weight during the audit period. These IPs are not simple "address camouflage" but real lines connected to local operators, which can provide network logs in line with local user habits. Brother Wang has made a comparison: when logging into the US site with a domestic IP, he received 2 "address audit" reminders a year; after switching to Yajuzhen's New York IP, the same account has been operating for 10 months, and the backend always shows "stable operation environment". Even the account manager took the initiative to invite him to participate in platform activities. II. Complete "Physical Isolation" Between Sites to Avoid Association Risks In terms of hardware, the US site has an independent IMEI and device serial number, equivalent to using a silver mobile phone; the Japanese site has another set of MAC addresses, like changing to a black mobile phone. These device information are never repeated, and what the Amazon backend sees is that three completely independent "physical devices" are operating. In terms of network, the IP tracks, login durations, and operation habits of the three sites are completely separated: the US site often uses "batch reply to emails", the German site prefers "manual price adjustment", and the Japanese site is used to "no new products on weekends". After these differences are recorded by the system, they will be judged as "three independent merchants" operating. A merchant selling 3C products once suffered a big loss — using 2 computers to log in to 4 sites, after the US site was complained about, all three European sites were involved in the audit. After switching to Yajuzhen, 6 sites operate in independent environments. Even if one of the sites encounters an infringement complaint, other sites are not affected and can normally receive orders. III. Improved Operation Efficiency and More Worry-Free Operation For multi-site operations, efficiency is as important as security. Yajuzhen Cloud Phone can open multiple site backends on one computer. Switching between the US site and the German site is like switching computer windows, without repeatedly plugging and unplugging the SIM card. When launching new products on the US site, product pictures and descriptions are stored in a dedicated folder, which will not be confused with the "Japanese copy" of the Japanese site; it can also preset "site-specific templates". The German site automatically has the "CE certification" logo, and the Japanese site displays "PSE certification" by default, avoiding audits due to missing information. The most practical is the "data encryption storage" function. The business license and tax documents of each site are stored in the corresponding environment. In case of an audit, they can be retrieved with one click, without rummaging through the computer to find files. Last time Brother Wang supplemented the "value-added tax certificate" for the German site, it only took 15 minutes from retrieval to submission, saving 2 days compared to before. Now Brother Wang often tells his peers: "Running multiple Amazon sites is not about the number of sites, but the ability to control risks. With Yajuzhen in the past six months, I have spent 80% less time worrying about audits and can focus on studying promotions on the US site and product selection on the German site — with fewer risks, I can focus more on making money."
