8 types of development

What do you need to build on Shopify?

Pick a type and see what we build, with which technology and what we check before quoting.

Custom apps

An app made for the way you operate.

When no app in the Shopify App Store solves your case, or you pay for three to get one thing done, we build your own: private to your store or public for other merchants.

Technology

  • Admin API
  • Polaris
  • Node.js

Examples of what we build

  • Admin panel for your team
  • Your own inventory or restocking rules
  • Connection to a supplier or internal system
  • Public app with documentation and support

Before building, we check whether an existing app already solves it. Sometimes that is the better option.

Before quoting

Does what you need live in Shopify or across your whole operation?

This page is for development inside Shopify. If your challenge includes marketplaces, branches or your ERP, Fenicia 360 fits better.

Frequently asked questions

Questions about Shopify development

Have a technical case that does not appear here? We will tell you how we would solve it.

Talk to an expert
Do I need Shopify Plus?
Not always. Many checkout and discount features are already in the standard plans. Plus makes sense for B2B, multiple stores or a high sales volume. If that is not your case, we will tell you.
I used Shopify Scripts. What do I do now?
Shopify retired Scripts. We rebuild those discount, shipping and payment rules with Shopify Functions.
Is the code mine?
Yes. What we develop for your store is delivered with its code and its documentation.
How long does it take and how much does it cost?
It depends on the scope. After understanding your case, we send you a proposal with a fixed timeline and price.
Is a headless store right for me?
Only if you need an experience a theme does not allow. It costs more to build and maintain, and for most stores a well-built theme is enough.
I want to connect Shopify with my marketplaces. Is this it?
That is what the Fenicia platform is for: it connects your Shopify store with Mercado Libre, Amazon, Walmart and more, with a single inventory. Learn about Fenicia 360.
