App developer in New York.
A client portal should reduce the work around a project, not create another place to check. For a New York agency or professional-services team, we can help turn scattered requests, files, and approvals into a clear path from intake to delivery.
A planning example for your business
Client approvals without the email chase.
Consider an agency managing several clients at once. A file is uploaded, a reviewer asks for changes, and an account manager needs to know which version was approved. Start with that handoff. Keep the client workspace separate from internal discussion, and make the next action obvious to both sides.
Your own workflow may look different. Bring an example of how your team handles it today, and we can shape the brief around that.
Before deciding what to build
A scope decision to make early.
A browser-based portal is a sensible starting point when clients participate occasionally. Discuss a mobile app only when repeat usage or device features justify the extra release process. Your existing document storage may remain the source of files rather than being copied into a second system.
Put the idea to a practical test
What should happen in a difficult case?
Test a client joining two projects with different access rights. Revoking one invitation must not expose or remove access to the other.

Before you get started
Questions worth asking.
Can each client have a different approval process?
Yes, but agree on which differences matter first. A configurable sequence of reviewers may be enough; building a separate workflow engine for every client can make the first release unnecessarily difficult to manage.
What should we bring to a portal scoping call?
Bring one completed project, an example approval email, and a list of who should see each file. Remove confidential information before sharing. These examples reveal requirements that a long feature wishlist often misses.
Can Dr App work with our team in New York?
Yes. We can discuss your project by phone or video, review examples of your current workflow, and agree on how feedback will be handled. Tell us about any on-site requirements before scoping the work.
