FlexiPurchase is a tool that is designed to help you to handle expenses on the go. All you have to do is select an expense that you want to code. You will then be taken to a screen where you can select the account to which you want to transfer the money. After selecting the account, you will be able to choose the payment type. You will also be able to add a comment for the transaction. You can do this for each expense that you have in your account, so you can keep track of the expenses that you are coding.
