Shopify custom apps
Custom Shopify apps for workflows themes cannot handle alone
Some requirements need a proper app: secure credentials, background jobs, admin UI, multi-store logic or API integrations. NP SoftTech develops custom and private Shopify apps that extend your store without stacking fragile theme hacks.

- Admin team repeats manual steps that an app could automate
- Integration scripts run on a developer laptop instead of reliable hosting

FAQs
Private app or public app?
Most client work is private or custom apps for one merchant or agency portfolio. Public App Store listings are scoped separately if you plan to resell.
Do apps require ongoing hosting?
Yes, if the app runs server-side logic or stores data outside Shopify. We explain hosting cost and options before build.
Can an app replace multiple marketplace apps?
Sometimes. If several apps overlap and cost adds up, a focused custom app can be cheaper long term. We compare honestly.
