1+x certificate is an e-commerce service launched by Alibaba, which aims to provide sellers with more professional and convenient online certificate services. In terms of operating a 1+x certificate online store, compared with traditional e-commerce stores, there may be some difficulties as follows:

1. Certificate knowledge: 1+x certificate online stores require sellers to have certain certificate knowledge, including the types of certificates, certification bodies, application procedures, etc. Therefore, if the seller does not have relevant experience and knowledge, some learning and training may be required.

2. Certificate application: 1+x certificate online stores require sellers to conduct certain audits and application process management for customers who purchase certificates, including auditing customer information, filling out application forms, uploading relevant certification materials, etc. This requires sellers to have certain management and operation capabilities.

3. Certificate quality: The certificate quality of 1+x certificate online stores is very important to buyers, so sellers need to ensure the quality and authenticity of certificates to avoid fake certificates or low-quality certificates.

It should be noted that the difficulty of operating a 1+x certificate online store may vary depending on the seller's experience and ability level. If you are trying to operate a 1+x certificate online store for the first time, it is recommended that you first undergo some learning and training to improve your own abilities and experience so that you can better cope with various difficulties and challenges in operation.
