Hi,
This is Madhumita from Techno Exponent, having 126 reviews in freelancer and we have more than 500 clients across the globe and our team strength is 50+.
I have gone through your requirement. You need a cash flow system which will support localizartion but must have Portuguese interface. It will represent the Incomings and outgoings of cash, calculating the opening balance and closing balance. Cash flow is increased by (1) selling more goods or services, (2) selling an asset, (3) reducing costs, (4) increasing the selling price, (5) collecting faster, (6) paying slower, (7) bringing in more equity, or (8) taking a loan.
So, in that case, I would like to know your detail requirement, that you need cash flow system for selling goods or selling an assets or for taking a loan.
Please come on chat for detail discussion on your system, after that we will make a detail doc explaining what we will do on your system and which technology we will use etc.
