DALY Custom Shopify App Development
When Off-the-Shelf
Doesn't Cut It.
Your business has unique workflows. We build custom Shopify apps that automate, integrate, and scale with you.
Built for Performance
Custom Public & Private Apps
Purpose-built Shopify apps — public or private — designed around your exact business logic. No compromises, no workarounds, no monthly app fees.
Product Customizers & Configurators
Let customers personalize products with real-time previews — engraving, color selection, bundle builders, and made-to-order configurators.
Third-Party API Integrations
Connect Shopify to any external system — CRMs, ERPs, 3PLs, marketing platforms, and custom databases via secure API integrations.
Inventory & Order Automation
Automate inventory updates, order routing, fulfillment workflows, and back-in-stock notifications. Less manual work, fewer errors, faster shipping.
Work That Speaks
Who This Is For
- Brands paying for 10+ apps that don't talk to each other
- Companies with unique product configuration needs
- Businesses needing custom ERP/3PL/CRM integrations
Project-Based Pricing
Final price depends on scope, complexity, and timeline. We provide a detailed quote after understanding your requirements.
Engineers Who Understand Revenue
We're not designers who learned to code. We're engineers who understand unit economics, ROAS, and pipeline velocity. Every system we build is measured by one metric: did it make you money?
We Build the Systems
Other agencies outsource the technical work. We write the code, build the integrations, and deploy the infrastructure ourselves.
Revenue Is the Only Metric
We don't report on impressions and clicks. We track leads, sales, ROAS, and revenue — the numbers that actually matter to your business.
No Fluff, No Filler
No 47-slide decks. No vanity dashboards. You get a system that works, data that's real, and a team that picks up the phone.
Built to Scale
Everything we build — campaigns, automations, integrations — is architected to grow with you. Not duct-taped together and prayed over.
Common Questions
When do I need a custom Shopify app?
When off-the-shelf apps don't solve your specific workflow, when you're paying for too many apps that don't integrate, or when you need custom product configuration tools.
What technology do you use to build Shopify apps?
We build with Gadget.dev and React for rapid development, plus Node.js and the Shopify API for more complex integrations.
How long does custom app development take?
Simple apps take 2-4 weeks. Complex apps with multiple integrations take 6-12 weeks. We scope every project before starting.
Can you build apps that sync with my ERP or 3PL?
Yes. We build custom integrations with ERPs (NetSuite, SAP, Bistrack), 3PLs (ShipBob, ShipStation), and CRMs (HubSpot, GHL).
Do you publish apps to the Shopify App Store?
We can build both private apps (just for your store) and public apps for the Shopify App Store.
