🤔 Problem Statement

Whenever we pay bills at shop, we get a bill's paper receipt which although is short in length but eventually when put together globally results in huge amount of paper loss.Also, we usually tend to throw away the bill receipts as it is difficult to file them, thereby refraining us to refer past bill details in future.

At times, it becomes difficult for shop owner to keep a track of his current available stock manually.There are chances of the bills being tampered by third party as well.

🚀 Solution

Thus, we have developed BillEase, a system wherein hardcopy of bills, i.e, paper bills are not generated at any point of time thereby making it environment friendly to save trees.

To make life of shop owner further easier, we have developed an inventory management portal for them wherein they can keep track of their product stock easily.Now, the entire bill generation and payment system will be carried out smoothly. Entire process can be further understood as shown below:
