Typical entry point
Free scan → paid audit → focused sprint → optional retainer.
Starting range
From CHF 1,500 for a focused sprint to CHF 12,000–30,000+ for a full growth system.
01 — The studio
A Zürich Shopify engineering studio.
What makes it engineering, not theme work.
Forgify is a Zürich-based Shopify engineering studio. Most agencies in this space sell themes, design and marketing retainers — we sit a layer deeper, in the code that runs your store. That means custom apps, Shopify Functions, webhooks, integrations and the automation that keeps an operation running without manual exports.
Engineering, not theme work, is a real distinction. A theme controls how the storefront looks; engineering controls how the store behaves — how orders are routed, how pricing rules resolve at checkout, how data flows to the systems behind the scenes. When a workflow needs an exception a generic app can't express, you've crossed into our territory.
We build for maintainability, not just launch day: typed code, minimal Shopify scopes, verified webhooks, structured logs and documentation a future developer can actually read. The goal is a store you own and can keep, not a black box you rent.
02 — What we do

Measured improvements to the storefront and checkout where the data shows real revenue is leaking.

03 — Find the leaks
CRO and revenue leak audits.
Before we build anything, we find where money already leaves the store. A conversion audit turns vague underperformance into a ranked, evidence-backed list.

05 — Local execution
Why local Swiss execution matters.
Being a Shopify Agentur Zürich is not just a postcode. It means understanding the market you sell into, the languages you sell in and the systems Swiss operations actually run on — then working at distance with the same rigour across Europe.
- Same timezone, same language
- Real-time collaboration in English, German and French — no overnight handoff lag.
- Swiss commerce context
- Local payment habits, fiduciary and accounting realities, and cross-border EU shipping.
- In-person when it counts
- We meet Zürich and wider Swiss clients face to face for kickoff and key decisions.
- Europe-wide delivery
- The bulk of the work ships remotely, so brands across Switzerland and Europe get the same standard.
