Shopify apps / Busan

Custom Shopify app development for stores in Busan.

Custom apps for what Shopify does not do out of the box, and our own apps for common problems.

ThinkAlgo is based in India and works remotely with store owners in Busan, the southeast coast: a written scope, one fixed price, and nothing paid until you like the first milestone.

The problem

What store owners tell us.

“Shopify cannot do this out of the box and no app does it right.”
“We need a discount rule the admin does not allow.”
“Two systems need to talk and someone copies data by hand.”
What you get

Shopify apps, delivered to a written scope.

Connections to other systems
Admin tools for your team
Discount, shipping and checkout rules
Our own apps, installable from the App Store
The right route chosen for your plan

Custom apps can use Shopify Functions for checkout and discount logic only on Shopify Plus. Stores on other plans get that logic through an App Store app. We choose the route with you before quoting. No sales popups or login popups: we do not build things that interrupt buyers.

For a store in Busan

What we account for locally.

Busan is Korea's largest port. Shopify Payments is not offered in South Korea, so stores here connect a Korean payment gateway and cannot use Shopify's own local-currency checkout. Brands selling abroad need a price and currency for each country.

TaxVAT applies, and prices are normally shown tax-included.
Payments and deliveryShoppers expect local cards, KakaoPay and Naver Pay, through a Korean payment gateway.
Selling abroadShopify Payments is not available to businesses in South Korea, so Shopify's own local-currency checkout is not an option. Our multi-country setup shows each country its own currency and price on the plan you already have.

General notes, not tax or legal advice. We confirm the details for your store in the written scope.

Questions

Before you ask.

Do you have an office in Busan?

No. We are based in India and work remotely with stores in Busan. Calls are booked at a time that suits Busan hours, and you get a reply within one working day.

Which currency do you quote in?

US dollars, fixed in a written scope. The KRW figures on this site are approximate conversions at the current rate.

Do I pay anything upfront?

No. We build the first milestone and show it on staging. If it is not what we agreed, you owe nothing. If you continue, 50% is due then and the rest on handover.
