Custom Shopify app development
Behind the scenes, the team prepares orders without opening a single spreadsheet. What the store couldn’t do, it now does without anyone seeing.
This service belongs to behind the scenes.
When no app in the Shopify App Store does exactly what your brand needs, Déclic builds it for you: a private app, built for your store, that fits into your Shopify admin and your theme. We then host and maintain it.
When the store is no longer enough
- You pay for three apps to get roughly one feature.
- A public app slows the store down or spoils the design.
- The way you sell fits no box: configurations, B2B sales, special pricing rules.
- Your team works around Shopify with spreadsheets.
What we build, step by step
- 01Map the need What customers see, what your team manages, and what existing apps already do well.
- 02Prototype Customer-side and admin screens, shown in motion.
- 03Build A private app, connected to Shopify, that loads only what it needs.
- 04Launch Tests on the live store, then activation without interrupting sales.
- 05Maintain Shopify evolves; we follow its changes so the app keeps working.
More control with Shopify Plus
Some features, such as custom checkout or discount rules, require Shopify Plus. We’ll tell you honestly whether your need calls for it.
Privacy as the difference
An app that touches customers and orders handles personal information. We design it under Quebec’s Law 25: only the data needed, limited access, and a privacy impact assessment when the project calls for one.
Hosting and maintenance
We host and maintain the app: updates, Shopify compatibility, security and support.

Frequently asked questions
Why not a public app?
It often works, and we’ll tell you so. Custom becomes useful when none does exactly what’s needed, or when it costs speed and image.
Will the app be listed in the Shopify App Store?
No. It’s private, installed only on your store.
Do we need Shopify Plus?
Not always. Only some features require it; we check from the start.
Will the app slow the store down?
It’s built to load only what’s essential, often lighter than several public apps combined.
Who handles maintenance?
We do. Hosting and maintenance are part of the service.
