how much does shopify app development cost? an honest breakdown
Ask Google what Shopify app development costs and you'll get numbers spanning two orders of magnitude - all of them technically true, none of them about your store. This is the honest version, from the developer who writes the quotes: what the price actually depends on, when a custom app beats another subscription, and how to walk out of a 20-minute call with a real number.
why every answer online is different
Because 'Shopify app' covers everything from a tiny automation that tags orders to a public App Store product with billing, onboarding and support. Those are different projects by a factor of fifty, and a price range wide enough to cover both is too wide to mean anything.
The quoting structure matters as much as the scope. An agency quote carries an account manager, a project manager and a sales margin before a line of code is priced. A solo developer's quote is the code. Same app, very different invoice.
what actually drives the cost
- What the app does with your data - reading products and orders is simpler than writing them, and writing with rules and edge cases is the real work
- Integrations - every external tool the app talks to (email platform, 3PL, spreadsheet) adds scope
- Interface or no interface - a headless automation is cheaper than an admin dashboard humans use daily
- Volumes and edge cases - an app for 50 orders a day is a different beast at 5,000
- Who maintains it - built-lean-and-boring costs less to own than clever-and-fragile
the subscription maths
The question that decides most custom app projects isn't 'what does it cost?' - it's 'what does the alternative cost forever?'. A $200/month app subscription is $2,400 a year, every year, for features you mostly don't use.
The published example from the case studies: The Protein Pancake's cart drawer was custom-built to replace the Rebuy subscription app - eliminating that exact $200/month. A one-time build that removes a rolling fee pays for itself on a schedule you can calculate before you commit.
And the honest counterpoint: some apps earn their subscription. A review platform, a complex loyalty programme - products with heavy ongoing platform features are usually worth renting. Where an app does one simple thing for a monthly fee, that's where custom wins.
how reedys quotes it
Flat, in plain English, after a 20-minute call: what I'll build, what it costs, when it lands. No discovery fees, no hourly meter, no surprise line items - and no agency layer in the price, because the person on the call is the person writing the app.
what to bring to get a number fast
- The workflow you want automated - a quick screen recording or a list of steps works
- The apps currently doing the job, and what they cost per month
- Rough volumes: orders per day, products, team size
- Who'll use it - just you, your team, or something customer-facing
