Dear Sir,
As I can see, you are having requirement of software that is based on .net and will perform the billing, sales record, customer record with edit, update features. I will provide you the same work, as I have done the same work before for book store and hotel management. I basically deal in desktop application as I am having the 6 years of experience in .net programming.
Awaiting for your response. I will execute your work in your minimum budget, on time.
Thanks,
Rahul Choyal
