Case Study — PSNY

Independent business and multilingual e-commerce

Products, customer touchpoints, international sales, website operations, and continuous improvement are managed as one business.

Business Overview

Operating products, sales, and the web as one business

My online retail experience began with PsLing sales in 2001. PSNY is the public English name of the sole proprietorship I have operated since 2014, selling women’s apparel, accessories, and PsLing products.

Operating Model

Three connected areas of operation

Products, sales, customer touchpoints, site operations, and improvement are handled as a continuous business process.

01 — PRODUCT & SALES

Products and sales

I operate the business across costs, products, sales, and customer touchpoints, covering women’s apparel, accessories, and PsLing products.

02 — MULTILINGUAL COMMERCE

Multilingual international sales

I built and operate a multilingual Shopify site and conduct international sales through e-commerce.

03 — CONTINUOUS IMPROVEMENT

Operations and improvement

I continue to manage information architecture, updates, and operations, using AI agents to support site improvement, code generation, and data processing.

PSNY ONLINESTORE

Designing multilingual, multi-currency commerce around sales and operations

Through my own Shopify store, I build and operate an environment where overseas customers can choose their language and currency before purchasing. This work brings together translation, selection flows, payment, and selling prices that incorporate country-specific shipping costs.

For example, a Japanese customer living in Singapore

By selecting Singapore as the delivery destination and Japanese as the language, a customer can browse products in Japanese and purchase in Singapore dollars. Selecting the country or region separately from the language accommodates needs that a customer’s place of residence alone cannot capture.

Start with customers when choosing languages and currencies

Designing multilingual commerce calls for more than adding translation features or currencies. It is important to analyze which customer groups in which countries or regions to prioritize, then decide how far to develop language support, currencies, product information, shipping, and customer inquiries. The example of a Japanese customer living in Singapore illustrates how language and purchasing behavior, as well as country, inform that design.

From the first visit to subsequent use

The store makes a browser-based selection and opens a selector on the first visit. After that, a band in the header provides access to language and currency settings.

Fixed prices incorporating country-specific shipping costs

The store supports both price display and payment in the respective currencies. Rather than using automatic conversion linked to exchange-rate fluctuations, it uses fixed prices incorporating country-specific shipping costs, with shipping shown as free.

Language support and pricing for the sales destinations are designed together.

AI-assisted configuration and implementation

I use AI for configuration and implementation on my own store. Multilingual and multi-currency support forms part of the ongoing work of selling products and operating the website.

Portfolio Perspective

Viewing the web from an operator’s perspective
