FAQ
What types of Shopify apps do you develop?
I build public apps for the Shopify App Store, private apps for individual store owners, and fully custom apps built around your specific business logic. Whether it's a simple integration or a complex multi-feature system, I can handle it.
How long does it take to develop a Shopify app?
It depends on the scope. A simple integration might take a few days to a week, while a more complex app with custom logic, webhooks, or third-party integrations can take several weeks. Once I understand your requirements, I'll give you a realistic timeline before we start.
What is the cost of developing a Shopify app?
Cost depends on the app's features, complexity, and how much custom logic is involved. I don't use flat pricing for anything beyond basic integrations, since every project's different. Message me with your requirements and I'll send a detailed quote.
Do you provide ongoing support and maintenance for the apps you develop?
Yes. I offer post-launch support to handle bug fixes, Shopify API updates, and any adjustments as your store grows. I can set this up as a one-time fix or an ongoing monthly arrangement, depending on what you need.
