At our company, we built our own e-commerce company with Shopify Hydrogen V2 atelier yori.so We started cross-border EC with multilingual and multi-currency support.
In conclusion, I think it is very good to do cross-border EC at Hydrogen so I share my learning.

technology composition

Cross-border EC is no different in terms of the EC, but as an element unique to cross-border EC, it is necessary to decide a target country and think about what to do with four points: language, currency, customs duties, and delivery methods.
As a result of consideration, the technology stack is as follows.

Front desk: Hydrogen V2
Hosting: Oxygen
Multi-currency and tax options: Shopify　Markets
Translation app: Shopify Translate & Adapt
Delivery: open log

Hydrogen has multi-language multi-currency support by default, so if you already have a site made with Hydrogen, I think that it is possible to multi-language and multi-currency support without tinkering with the code.
And here’s an explanation of what we used on the backend.

multicurrency correspondence

For starters, Shopify has built-in multi-currency support. with market function You can set the target country and make necessary settings.
With this Shopify Market feature, you can set up a cross-border EC without translation.

• Since there are products that cannot be sent in some countries, the bulk setting of goods sold domestically and not sold overseas
• a bulk setting of how many times the price is taken from domestic prices and how to reflect exchange rates)

This feature is especially useful.

Responding to laws, treaties and crude taxes

Please note that there are products that cannot be delivered due to laws and treaties in some countries.
There is a detailed description on the international post page of the post office, so for details here Please refer to the link below.

and in europe EU General Data Protection Regulation (GDPR) If you want to sell your personal information in Europe, we will need to revise our e-commerce site according to these requirements.

In some countries, there are tariffs related to import/export, goods tax which is associated with the type of product such as liquor tax and value-added taxes equivalent to consumption tax in Japan.

If you sell goods to the end user without confirming this part, it is necessary to be careful because even if a product does not arrive or reaches, it will cause a rejection.

With Shopify’s premium plan and more available market features, it can automatically set up and collect taxes in advance, so you should also consider that feature.

Multilingual Support

Shopify has a variety of translation apps, but they’re official Translate and Adapt It is very convenient and first choice.
In particular, I thought the following points were useful.

• autotranslate
• You can customize and add your own meta objects, meta fields or other items in multiple languages * Create a new field for that language and branch the code with an if statement.

Delivery

There are many companies that can handle cross-border EC, but we are taking care of delivery for domestic customers. open log I asked you.
It is very convenient because it automatically cooperates with Shopify and the order will be delivered automatically at home and abroad.

Benefits of Cross-Border E-Commerce with Headless Commerce

By creating a site for Japan with Shopify theme and making it in headless commerce overseas, the biggest advantage is that “the front end can be independent while the backend is integrated”.

Since the backend is integrated, inventory management and so on remain centrally managed, you can completely separate design from domestic at front end and overseas, so you can build a site that suits foreign languages and targets.
Therefore, it can be said that this is the best for e-commerce sites with a particular emphasis on branding.

Also, in the unlikely event that cross-border EC does not go well, the front end is independent when withdrawing, so it can work without affecting domestic sites.

Our company also accepts cross-border e-commerce sites for headless commerce, so if you are concerned here for more information.
Thank you very much.
