Consulting Cases

  • Company A (Early Stage)
    ・Interested in starting cross-border EC
    ・Platform selection concerns

    A社 (初期)・越境ECこれから始めたい・プラットフォームの悩

    We are struggling to determine the right platform for our company in terms of building an e-commerce website. We are considering options like Shopify, Magento, and WooCommerce. We also need to synchronize our inventory with domestic e-commerce sites and online marketplaces.


    We will gather information about your products, target countries, inventory synchronization with other platforms, coordination with domestic e-commerce, budget, and the expertise and literacy of your e-commerce team. Based on this, we will provide an overview of the pros and cons of different e-commerce platforms and assist you in selecting the most suitable one. We will also offer guidance on implementation and operation.

  • Company B
    ・Currently operating cross-border EC
    ・Aim to enhance sales and expand sales channels


    Even after one year of establishing a cross-border EC website, we have not achieved the planned sales targets. Additionally, due to changes in our business structure, we find the current platform difficult to use. We are planning to expand our distribution channels by selling on multiple international e-commerce marketplaces.


    Many times, the scale and size of the company do not align with the operational requirements, making low-cost operations challenging. In such cases, it is advisable to conduct small-scale test marketing on platforms with proven sales performance. We can provide comprehensive advice, including transitioning to specific e-commerce platforms, reducing prices and shipping costs, and implementing strategies to facilitate expansion and growth.

  • Company C
    ・Facing challenges in system development
    ・Concerns regarding infrastructure investment


    We are using an open-source platform for our e-commerce website, and our servers are on the cloud. However, the infrastructure is unstable, and each additional development incurs unexpected costs and delays. Should we consider changing the platform?


    There have been numerous cases where platforms have been used in a manner that closely resembles scratch development. Our engineers can assist in creating an architectural diagram and providing advice on infrastructure when undertaking improvements and new development. In addition to investment, we can support you in alleviating concerns using j-Grab's proprietary methods that provide cost-effective solutions.

Frequently Asked Questions

I am a complete beginner in overseas sales. Is it possible to learn cross-border EC in a short time?

It is possible to deepen a comprehensive understanding of the basics and operation of cross-border EC in as little as one hour. This is not a one-way seminar, but rather a one-on-one consultation where questions and doubts can be raised and solved during the course of the discussion. It is recommended that you prepare your own agenda and questionnaire to make the consulting time even more intensive.

Is there any problem if I consult with you not only about cross-border EC but also about domestic EC?

No problem. j-Grab has an established reputation for cross-border and domestic EC consulting. We can handle a variety of issues including domestic and international EC platforms and malls, SEO, customer acquisition, advertising, and customer success, etc.

I consulted with the national support organization, but could not get an accurate answer....

Even if you consult with staff at JETRO, the Small and Medium Enterprise Corporation, or the Chamber of Commerce and Industry about cross-border EC, it is possible that you will not get good advice if the person you consult with is not a specialist in cross-border EC. It would be better to use them only for advice. We are active cross-border EC consultants specializing in cross-border EC, so please feel free to ask us any questions you may have. We are able to answer and resolve most of your questions and concerns.

I am wondering if I should get an FDA. I would also like to discuss tax and intellectual property matters.

We also provide consultation on standards and certifications, as the rules for B2B trade and B2C cross-border EC customs clearance differ greatly, and the rules for acquiring FDA vary depending on the EC mall in which you open your store. We also provide appropriate advice on Kansai and intellectual property rights. We also introduce accounting firms and services that specialize in cross-border EC.
