App Replacement ROI

A custom app can reduce monthly app fees and remove friction from your operations.

2 apps at $99/mo each
$198/mo$2,376/yr
3 apps at $79/mo each
$237/mo$2,844/yr
4 apps at $49–149/mo

A custom build typically costs $1,500–$6,000 depending on complexity. Most clients recover the cost in 6–18 months and pay nothing recurring after that.

App Types

From private tools to App Store products

Private Apps

Most common

Built exclusively for your store. Never published. Faster to build, lower cost, no review process. Ideal for replacing paid apps, building internal tools, or adding functionality Shopify's API supports but no app offers cleanly.

Product drop systems
Custom loyalty programs
ERP sync apps
Internal admin tools

Shopify Functions

Shopify Plus

Customise checkout logic at a level no standard app can reach — discounts, shipping, payment options, cart validation. Only available on Shopify Plus. We've built Functions for tiered pricing, stacking discounts, and conditional free shipping.

Custom discount stacking
Tiered B2B pricing
Conditional shipping rules
Cart validation logic

Public Apps

App Store

Apps listed on the Shopify App Store available for any merchant to install. Require Shopify's review and approval. We handle the full submission process — architecture, OAuth, billing, and App Store listing optimisation.

Embedded admin apps
Checkout UI extensions

Our Guarantees

We stand behind our work — in writing.

🔒

Fixed-Price Before We Start

Every app is scoped and priced before a single line of code is written. No hourly billing, no surprise invoices — you know the full cost upfront.

⚙️

Shopify-Native Architecture

Built using Shopify's official APIs, App Bridge and CLI standards — not hacks. Your app will pass Shopify's review process and survive every API version upgrade.

🛠️

Maintained Post-Launch

We offer ongoing maintenance packages. Shopify releases new API versions twice a year — we keep your app compatible and running at every update.
