Custom Shopify Apps & Backoffice Automation
When off-the-shelf apps can’t handle your proprietary warehouse logic, custom pricing rules, or ERP connections, AeroCodix builds scalable custom Shopify Apps using Remix, Node.js, and GraphQL.

Bespoke Software Infrastructure Tailored to Your Supply Chain
We build secure private apps that automate drop-shipping routing, sync live pricing with suppliers, enforce B2B custom credit limits, and integrate seamlessly with custom ERPs.

Frequently Asked Questions
Have questions about engagement models, delivery timelines, or technical specifications?
What is the difference between a Private Custom App and a Public App?
A Private Custom App is built specifically for your store’s internal operations (ERP sync, proprietary algorithms) and installed only on your account. A Public App is listed on the Shopify App Store for thousands of global merchants to install and pay for.
How do you prevent rate-limit errors during high-volume sales?
We architect our apps with asynchronous message queues (Redis/BullMQ) with exponential backoff and GraphQL cost budgeting to guarantee 100% webhook delivery without hitting Shopify API throttles.
