Hi
I have gone through your requirement of store management app. As a tenured software developer, I am sure I can help you in this project. I typically take 6 to 7 days for a complex project. Since your project is not that complex, I can do it earlier or as per your need.
I have been developing software since last 5 years and I am sure I have ample understanding of your project. I have already done and delivered library management and boutique management projects in C language to different firms; so can also develop store management project efficiently.
I assure you to do this project accurately and with great customer satisfaction.
I hope to work with you soon.
Thank you
