Shopify apps / Zagreb

Custom Shopify app development for stores in Zagreb.

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 Zagreb, the City of Zagreb: 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 Zagreb

What we account for locally.

Zagreb is Croatia's capital and largest consumer market. Croatian stores still see cash on delivery chosen often, and many sell to Slovenia and the wider EU with delivery promises that differ by country.

TaxVAT applies, and sales to shoppers in other EU countries usually go through the One Stop Shop scheme.
Payments and deliveryShoppers expect cards and cash on delivery.
Selling abroadShopify Payments is available to businesses in Croatia, so local currencies work through Shopify's own markets settings. We set up prices, rounding and shipping per country and keep them right.

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 Zagreb?

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

Which currency do you quote in?

US dollars, fixed in a written scope. The EUR 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.
