Launch on iOS and Android in 2 to 3 weeks from kickoff, on a fixed scope. The commerce foundation is already built, so the work goes into your brand.


## Stop rebuilding mobile commerce infrastructure

Every mobile commerce project rebuilds the same things. Cart. Checkout. Authentication. Order history. Product variants. None of it is differentiating, and all of it takes months.

StorefrontOS ships that foundation production-ready and synchronized with Shopify. What remains is the part that is actually yours: how the store looks, how it merchandises, and how it speaks.

- Launch in 2 to 3 weeks from kickoff
- Roughly 80% less engineering scope, focused on brand rather than plumbing
- One price for the scope you signed, with no change-order surprises
- Direct Storefront API integration, so there is little new backend to run
- An owned customer channel, independent of marketplace apps

## StorefrontOS, or building it again


| | Building from scratch | On StorefrontOS |
|---|---|---|
| Time to launch | 3 to 6 months from kickoff, every project, because the foundation is rebuilt each time. | 2 to 3 weeks from kickoff. The production foundation exists on day one. |
| What the engineering buys | Cart, checkout, auth, variants, and order history, built from zero. | Brand, content, and merchandising. Roughly 80% less scope, aimed at the part that is yours. |
| How it is priced | An estimate, plus the change orders nobody warned you about. | Fixed scope, one price, agreed before work starts. |
| The backend you run | A parallel commerce backend to design, secure, and scale. | None. Native clients read the Shopify Storefront API directly. |
| Who owns maintenance | You do, and it compounds. Every OS release is another sprint. | We do. OS updates, SDK changes, and security patches come with the platform. |
| Where the catalog lives | Synced into a second system, then reconciled when the two disagree. | Shopify stays the source of truth for products, inventory, pricing, and customers. |

## Six stages, already engineered

- **Discover**: Customizable home modules with CMS-controlled layouts.
- **Browse**: Product grids with filters, search, and variant previews.
- **Detail**: Product galleries with native add-to-cart.
- **Convert**: A native cart handing off to Shopify checkout.
- **Retain**: Customer profiles, order history, and authentication options.
- **Operate**: Real-time Shopify sync, push notifications, multi-market support, analytics.

## Built directly on Shopify, with minimal backend

The native clients talk to the Shopify Storefront API. There is no intermediate commerce service holding a second copy of your catalog.

StorefrontOS Core sits on top of that and handles the parts an app needs and a storefront does not: UI, state, routing, the content layer for home modules and editorial, sync, and analytics. Products, inventory, pricing, customers, and orders stay in Shopify, where your team already manages them.

Checkout hands off to Shopify's own checkout, including Shop Pay and Apple Pay. That keeps PCI scope where it already sits rather than extending it into your app.

- Fewer moving parts, so fewer places for it to fail
- No parallel commerce backend to design, secure, or scale
- Lower total cost of ownership, because there is less of it to own
- Shopify stays the source of truth, so your team's workflow does not change

## Three Moves to a Native App

Connect the store: Products, collections, inventory, pricing, and customers sync through the Storefront API. No data migration and no parallel system, because nothing is being copied anywhere. (Storefront API, webhooks, multi-store)
Make it yours: Color, typography, navigation, home layouts, and editorial content are configured. This is where the engineering scope goes, and it is the only part that is actually about your brand. (Theme tokens, home CMS, brand assets)
Ship to both stores: Submission to the App Store and Google Play on the StorefrontOS release pipeline. Content and merchandising updates ship afterwards without another app review. (App Store, Google Play, over-the-air updates)

## Ships as Your Brand, Not a Template

One foundation, three merchants. Color, typography, layout, navigation, and content modules are all yours to shape. The plumbing stays out of sight.


## What this replaces in practice

A traditional mobile agency will typically quote three to six months and a six-figure budget for the same outcome, because they are quoting the reconstruction of commerce basics alongside your brand.

StorefrontOS is a fixed-scope engagement. The exact figure depends on what your store needs, which we establish on a discovery call rather than by publishing a number that would be wrong for most merchants.


## Book a 30-minute demo

We look at your store before the call, so what you get is a launch plan for yours rather than a generic walkthrough. You leave with engineering scope and a fixed timeline in writing.


## Everything Merchants Ask First

### Why not just use the Shop app or a responsive site?

The Shop app is Shopify's marketplace, so your customers land in a feed alongside every other merchant. A responsive site cannot reach push notifications, deeper iOS and Android features, or the home screen. A native app on StorefrontOS is your own channel: your icon, your push, your brand end to end.
### What happens to my Shopify store?

Nothing changes. Your admin stays the source of truth for products, inventory, pricing, customers, and orders. The app reads the Storefront API in real time and checks out through Shopify's own checkout, including Shop Pay and Apple Pay. No migration and no parallel system.
### Do I own the app and the code?

You own your brand experience, your customer data, your push channel, and your App Store listings. StorefrontOS is the platform underneath, and we maintain it so OS updates, SDK changes, and security patches arrive without a rebuild. The relationship is close to the one Shopify already has with your store: the platform is managed, the brand is yours.
### Will it really launch in 2 to 3 weeks?

Yes, because the commerce foundation is already built and tested. Those weeks cover connecting Shopify, brand customization, content configuration, QA, and submission to both stores. What moves the date is content readiness on your side, not engineering on ours, and we will say so during scoping if that looks like the risk.
### How much does it cost?

It is a fixed-scope engagement: one price, one timeline, no change-order surprises. The number depends on how deep the brand and content work goes. A 30-minute call is enough to scope it against your store and send a written quote.
### What if I need custom features later?

StorefrontOS is modular, so extending it is a scoped piece of work rather than a rewrite. Loyalty, subscriptions, and custom merchandising are the common ones, and they get priced in story points like any other scope.
### What about Android?

iOS is the primary platform at launch and Android is shipping shortly. If Android is critical for your market, say so on the demo call and we will share the current timeline rather than a hopeful one.
