Dear hiring manager,
I'm a mobile app developer, and I can perfectly build the warehouse app for you. Both web and mobile solutions are possible, however I think a mobile app with offline functionality would be a better choice for this kind of functionality.
I've a few questions, because I believe they might affect the price and time for finishing this project.
1- Do you need for Android/iOS or both?
2- Do you want to run Admob (or other) ads?
Looking forward to response from you. Just give me a chance and I'll make sure you are 110% satisfied with my work.
Regards.
Faraz Ahmad
