Shopify App Development Cost in 2026: Private vs Public App Store Pricing
Quick answer
Shopify app development costs in 2026: ₹4–15 lakh for a private app serving a single Plus merchant, ₹6–18 lakh for a public single-feature App Store app, ₹15–40 lakh+ for multi-feature SaaS-grade public apps. App Store review takes 4–8 weeks on top of 6–14 weeks of build. Ongoing maintenance runs ₹40K–₹2L/month — non-negotiable because Shopify drops three API versions per year.
Shopify app development pricing is the wild west — quotes range from ₹50,000 (someone's nephew building on Bubble) to ₹50 lakh (a US agency white-labelling Indian devs). Here's what an honest build actually costs in 2026, why private and public apps aren't the same product, and what the hidden ongoing costs look like.
Four engagement tiers and 2026 cost ranges
| Engagement | Build cost (2026) | Timeline |
|---|---|---|
| Private app (single Plus merchant) | ₹4 L – ₹15 L | 6–10 weeks |
| Public app (single feature) | ₹6 L – ₹18 L | 8–14 weeks + 4–8 wks review |
| Public app (multi-feature SaaS) | ₹15 L – ₹40 L+ | 16–28 weeks + review |
| Maintenance + roadmap | ₹40K – ₹2 L / mo | Ongoing |
Why private apps are cheaper than public apps
A public Shopify app — listed on the App Store — needs everything a private app needs plus:
- GDPR webhooks (mandatory for App Store listing): customers/data_request, customers/redact, shop/redact. Tested and audited.
- Multi-shop architecture: the app installs cleanly across thousands of stores with different configs. Private apps just need to work on one store.
- Shopify Billing integration: recurring or usage-based plans, free trials, upgrades, refunds — wired against Shopify Billing API.
- App Store assets: screenshots, demo video, listing copy, support FAQ, privacy policy, data- handling documentation.
- Reviewer rounds: 70% of first submissions get reviewer notes. Each round is 3–7 days of dev + QA + resubmission overhead.
The same core workflow built as a public app is typically 30–60% more expensive than the private version, because you're paying for distribution surface, not just the feature.
Where the build money actually goes
A ₹10 lakh single-feature public Shopify app build in 2026 breaks down roughly:
- Spec + feasibility (8%): ₹80K. Defining the workflow, mapping Shopify API surfaces, flagging policy risks before code is written.
- Polaris UX design (12%): ₹1.2L. Embedded admin design using Shopify's Polaris components — reviewers reject apps that don't feel native.
- Backend on Remix / Next.js (25%): ₹2.5L. OAuth flow, session tokens, webhook handlers, GraphQL Admin API integration, background jobs.
- Admin embed frontend (20%): ₹2L. App Bridge integration, Polaris UI, embedded admin pages.
- Billing + GDPR (10%): ₹1L. Shopify Billing API plans, GDPR webhooks, data-handling policies.
- QA + multi-shop testing (10%): ₹1L. Test stores across plans, OAuth scenarios, webhook reliability, uninstall cleanup.
- App Store submission (8%): ₹80K. Listing copy, screenshots, demo video, reviewer responses.
- PM + buffer (7%): ₹70K. Buffer for reviewer revision rounds.
The hidden cost: Shopify's API version cycle
Shopify drops three new Admin API versions per year (typically Jan, April, July, October) and deprecates each one ~12 months later. An app left on a deprecated version starts returning 410 Gone errors on removed fields and webhooks. Merchants see broken features. The App Store starts flagging the app.
Maintenance retainers exist for this reason. ₹40K–₹2L/month covers:
- API version upgrade (3× per year, typically 1–3 days dev each)
- Polaris and App Bridge SDK version bumps
- Deprecated webhook migration
- Bug fixes and merchant-reported issues
- Reviewer follow-ups if the App Store flags anything
- Small feature additions within retainer scope
What public Shopify apps actually earn
Honest distribution of Shopify App Store revenue in 2026 (across ~13K listed apps):
- Top 1% of apps: $50K–$5M/month MRR. Dominated by 10-year-old entrenched apps (Klaviyo, Judge.me, Loox, Recharge).
- Top 10%: $5K–$50K/month MRR. Usually category leaders for a specific workflow.
- Median listed app: $200–$2,000/month MRR. Most apps don't cross break-even on the engineering investment.
- Bottom 50%: under $500/month MRR. Mostly hobby projects, copycat apps, or apps with no marketing strategy.
Build a public app to solve a real workflow gap with a clear distribution plan — partner channels, niche communities, paid install ads. Don't build one because the App Store sounds attractive.
When a private app beats a public app
Private apps win when:
- The workflow is specific to your business or your one anchor client.
- The Shopify Plus surfaces you need (Functions, B2B, checkout extensions) are Plus-only by definition.
- Competitive advantage matters — you don't want competitors installing the same app.
- Speed-to-launch matters — skip App Store review, ship in 6–10 weeks instead of 10–18.
The verdict
Budget ₹4–15 lakh for private apps, ₹6–18 lakh for single-feature public apps, ₹15–40 lakh+ for SaaS-grade multi-feature apps — plus ₹40K–₹2L/month ongoing for the Shopify API version cycle. Anyone quoting below those ranges is either cutting corners on review- critical surfaces (GDPR, Billing, Polaris compliance) or under-quoting and they'll blow scope when reviewer notes come back.

Frequently asked
How much does it cost to build a Shopify app in 2026?
Private app for a single Plus merchant: ₹4–15 lakh. Public single-feature App Store app: ₹6–18 lakh including listing assets and first reviewer revision round. Multi-feature SaaS-grade public app: ₹15–40 lakh+. Plus ongoing maintenance of ₹40K–₹2 L/month to handle Shopify's three API version drops per year.
Private vs public Shopify app — which is cheaper to build?
Private apps are cheaper because there's no App Store review queue, no listing assets, no marketing surface, no GDPR webhooks for non-EU merchants, and no multi-shop edge cases. A private app for one specific Plus merchant typically costs 30–50% less than the equivalent public-listed version of the same workflow.
How long does Shopify App Store approval take in 2026?
First submission review takes 2–4 weeks. If the reviewer requests changes (typical for ~70% of first submissions), expect 3–7 days for each round of revisions. Total time from feature-complete app to live App Store listing is usually 4–8 weeks, on top of 6–14 weeks of build time.
What ongoing costs do Shopify apps have after launch?
Hosting (AWS/Fly.io/Vercel/Hostinger Node): ₹2K–20K/month depending on scale. Shopify Partner fees: 0% on first $1M lifetime revenue, then 15% after that (down from 20% previously). Shopify's three annual API version drops require ₹40K–₹2L/month of dev time for upgrades. Plus optional CS, listing optimisation, and feature roadmap retainers.
Do Shopify Plus merchants need different apps from standard merchants?
Often, yes. Shopify Plus exposes APIs that standard plans don't — Checkout Extensions, Shopify Functions for discount/shipping/payment logic, B2B catalogs, multi-store synchronisation, and Plus-only webhooks. Apps that use these surfaces only work on Plus stores by definition. Most enterprise-grade custom app builds target Plus specifically.
What happens if I don't maintain my Shopify app?
Shopify drops three API versions per year and deprecates each one ~12 months later. An app left untouched for 18 months will start hitting deprecation warnings, then 410 Gone errors. Merchants will see broken features. Apps that haven't been updated in 12+ months also risk delisting from the App Store. Plan for ongoing maintenance from day one.
Can I monetise a public Shopify app — and how much do they make?
Yes — via Shopify Billing API (recurring, usage-based, or one-time). Top-decile public Shopify apps make $10K–$500K/month MRR in 2026. Median public app makes $200–$2,000/month. Distribution follows a power law: hits dominate, most apps make pocket change. Build a public app to solve a real problem with measurable distribution, not because the App Store ecosystem sounds attractive.
