Choose the delivery surface from the user's task. The same business idea can have very different cost and operating needs depending on where and how people use it.
Compare the practical requirements - Web app: useful when users can work in a browser and you want a central release path. Check supported browsers, access, performance and any offline requirement. - Mobile app: consider device capabilities, repeated mobile use, notifications and distribution. Account for app-store processes, device testing and ongoing platform updates. - Customer portal: often a web application, but its key questions are company access, roles, documents, requests and connections to your existing systems. - Commerce platform: an existing shop platform may already cover catalog, checkout and order workflows. Clarify what should be configured and which integration or product requirement needs custom code.
A portal is not automatically a native mobile app. An app-store presence is not automatically useful to the buyer. List the device and access requirements that change the decision before choosing a framework.
Offlinery provides mobile-product context; MyMerch illustrates improvements to an existing commerce business. Their scopes should be compared with your own needs.
Use the service overview for the available routes.
Bring: the main user, where they work, one complete task, required device features and the systems already in place. These details help avoid building two separate products when one well-chosen surface could work.
