Shopify app development services
Shopify apps, built by a team that ships its own.
Shopify app development is building software that extends a Shopify store — public App Store apps, private apps for a single store, app extensions and API integrations. PRP Webs has built and published its own Shopify apps, so we know the whole journey from idea to live on real merchants' stores.

What we build
Public Shopify App Store apps
We design, build, submit and maintain apps for the Shopify App Store — including our own published apps. We handle the full lifecycle: OAuth, billing API, App Store review requirements, and ongoing updates.
Private & custom apps
Apps built for one store only — admin extensions, custom workflows, automations and checkout UI extensions that fit exactly how your team works, with no public listing.
App & API integrations
Connect Shopify to the systems you already run — ERPs (NetSuite, SAP), CRMs (Salesforce, HubSpot), PIMs, 3PLs and payment or marketing tools — via the Admin GraphQL API, Storefront API or custom middleware.
App maintenance & growth
Launch is the start. We ship updates, add features, keep apps compliant with Shopify API versions, and improve performance and revenue release after release.
Apps we've built and published
We don't just talk about app development — we ship and maintain our own apps on the Shopify App Store. That means we've passed Shopify's review, handled billing and OAuth, and supported real merchants.

Why choose PRP Webs for Shopify app development
Shopify Partner & App Developer
We are a Shopify Partner with apps published and live on the Shopify App Store — proof we can take an app from idea through Shopify's review process to real merchants.
We build our own products
Beyond client work we conceptualised and built our own products (including the AI platform Dyzo) — so the skills we bring to your app are battle-tested on our own.
Transparent, you own the code
A clear, itemised quote with fixed milestones before any work starts, full progress visibility in Dyzo, and 100% code ownership — no lock-in.
Our app development process
- Discovery & scope. We learn what the app must do, who uses it, and how it should make or save money — then write a clear scope.
- Design. We design the merchant/admin experience so it is simple to use, not just functional.
- Build. We develop the app against Shopify's latest APIs, with version control and proper testing.
- Test & submit / deploy. We test thoroughly, then submit to the App Store (for public apps) or deploy privately to your store.
- Maintain & grow. We keep it updated, compliant and improving — new features, fixes and performance.
Frequently asked questions
What is Shopify app development?
Shopify app development is building software that adds features to a Shopify store — either a public app listed on the Shopify App Store for any merchant, or a private/custom app built for a single store. It uses Shopify's Admin GraphQL API, Storefront API, app extensions and Functions.
What is the difference between a public and a custom (private) Shopify app?
A public app is listed on the Shopify App Store and any merchant can install it; it must pass Shopify's review and handle billing and OAuth. A custom (private) app is built for one store only, not listed publicly, and is ideal when you need bespoke workflows or integrations just for your business.
Can you publish an app on the Shopify App Store?
Yes. We have built and published our own apps on the Shopify App Store (PW Stock Notify, PW Store Locator and PW Announcement Bar), so we know the full process — OAuth, the billing API, App Store review requirements and post-launch updates.
Can you build a private app just for my store?
Yes. We build custom apps installed only on your store — admin extensions, automations, checkout UI extensions and integrations tailored to your exact workflow, with no public listing.
How much does Shopify app development cost?
It depends entirely on scope — a small private automation is very different from a full public App Store product. Rather than a vague range, we scope the work and give you a fixed, itemised quote with milestones before development begins.
Can you integrate Shopify with third-party systems and APIs?
Yes. We connect Shopify to ERPs (NetSuite, SAP), CRMs (Salesforce, HubSpot), PIMs, 3PLs and other tools using the Admin GraphQL API, Storefront API or custom middleware, with real-time sync.
Do you maintain and update apps after launch?
Yes. We keep apps compliant with Shopify's API versions, fix issues, add features and improve performance over time — we run this cycle on our own published apps too.
How long does Shopify app development take?
A simple private app can take a few weeks; a full public App Store product with billing and review takes longer. We give you a fixed week-by-week plan before we start.
