E-commerce site
Products, payments and shipping notifications, done in one go
Self-built or open-source-based shops: products and stock, Taiwanese payment gateways (ECPay, NewebPay), e-invoices, logistics, LINE notifications and a back office. We run an e-commerce business ourselves and know where it gets stuck.
A good fit when
- You have products and customers and want your own brand store
- Need Taiwanese payment, e-invoice and logistics integrations
- Want LINE for after-sales and re-marketing
Not a fit when
- Only need to list on Shopee or other marketplaces
- Products and supply are not confirmed yet
What you get
- 01A transactional store with back office
- 02Payment, e-invoice and logistics integrations
- 03Order notifications and reports

eSIM 226 storefront
A travel eSIM store in eight languages with multi-currency pricing and two Taiwanese payment gateways. Paid orders are provisioned with the upstream supplier automatically and the install email goes out on its own.
- Eight locales and multiple display currencies, so Japanese buyers see yen
- Automatic provisioning across two suppliers, with failover

eSIM back office
The operations side of the same store: products, pricing, orders, refunds, suppliers and payments in one place. It actively surfaces problems like "paid but never fulfilled" instead of waiting to be asked.
- Orders, revenue, unpaid and unfulfilled counts at a glance
- AI pricing suggestions and bulk listing changes
