How much does a custom Shopify app cost in Switzerland?

It depends on scope. A focused custom app sprint typically runs CHF 4,000–15,000+; larger growth systems with several integrations run higher. The cheapest way to scope it accurately is a short audit before committing to a build — no fixed quote before we understand the workflow.

You do, per the engagement contract. We hand over the repository, documentation and deployment details so you are never locked in. Ongoing maintenance is optional, not a hostage situation.

Do you work with Shopify Plus?

Yes. Plus features — Functions, checkout extensibility, B2B, Flow — are often exactly where custom engineering pays off. We also build for standard Shopify plans where a private app is the right fit.

Can a custom app replace several plugins?

Often, yes. Where several overlapping apps add scripts, fees and data drift, a single private app built around your workflow can replace them — fewer dependencies, cleaner data and less subscription sprawl. The audit tells us which apps are worth replacing and which to keep.

Custom Shopify app development in Switzerland

Forgify builds private Shopify apps, admin dashboards, Shopify Functions, ERP integrations and automation systems for stores that have outgrown generic plugins — based in Zürich, working across Switzerland and Europe.

Starting range

01 — The discipline

Engineering, not another plugin install.

Custom Shopify app development, defined plainly.

Custom Shopify app development means building software that runs against the Shopify Admin GraphQL API and embeds in your admin — shaped around how your business actually operates, instead of bending your operation around a generic app's assumptions.

A private app can read and write orders, products, customers and inventory; react to events through webhooks; add merchant-facing screens with App Bridge and Polaris; and enforce business rules at checkout with Shopify Functions. It is the difference between renting features and owning a tool.

We build for maintainability, not just launch day: typed code, minimal scopes, verified webhooks, structured logs and documentation a future developer can pick up.

02 — The signal

When generic apps become too limited.

The moment a workflow needs an exception the app can't express, you've outgrown it. Common triggers:

GraphQL Admin APIShopify FunctionsApp BridgePolarisWebhooksMetaobjects

Workflow exceptions: Your rules need a branch the app's settings simply don't have.
Data living in spreadsheets: Operators export, edit and re-import because the app won't model your data.
App stack tax: Five overlapping apps, five subscriptions, five sets of scripts slowing the store.
Integration gaps: Your ERP, CRM or fulfilment system has no clean, reliable bridge to Shopify.

Sync

04 — Integrations

Connected to the systems behind the store.

Shopify is the commerce layer. Your ERP, CRM, fulfilment and accounting tools are the operational truth. We wire them together reliably.

ERP & inventory: Two-way sync for stock, products and pricing with queues and error handling.
CRM & customers: Customer and order data flowing to your CRM without manual exports.
Fulfilment & shipping: Orders pushed to fulfilment, tracking pulled back, statuses kept in step.
Accounting & fiduciary: Clean exports for Swiss accounting and fiduciary workflows.

05 — Custom vs public

A private app is not a listed app.

Public App Store apps optimise for the average store. A private app optimises for yours — and only requests the access it needs.

Scope: Public apps carry features and scripts you'll never use. Private apps do only your job.
Access: Minimal Shopify scopes, not the broad permissions a public app often requests.
Roadmap: Your priorities drive the backlog — not a vendor's average customer.
Cost shape: A build plus optional maintenance, instead of per-seat fees that scale against you.

06 — Scope & handover

Diagnose, scope, build, hand over.

A typical custom app sprint runs 2–4 weeks. Pricing from CHF 4,000–15,000+ depending on scope — cautious ranges, no fake guarantees.

Diagnose — we map the workflow, data model, integrations and edge cases before any code.

Scope — a written plan: surfaces, scopes, events and the smallest version that delivers value.

Build — typed code against the GraphQL Admin API, tested and instrumented.

Ship — careful deploy, then documentation, handover and an optional maintenance plan.

07 — FAQ

Questions before scoping a build.

A custom (or private) Shopify app is software built specifically for your store rather than listed publicly. It runs against the Shopify Admin GraphQL API with only the scopes you need, and can add admin dashboards, automation, custom checkout logic or integrations that no off-the-shelf app expresses cleanly.
