There is no need for you to do anything for invoice process, the site itself gives you that and following it, a clickable details tab is provided where you have click and do the further typing of information for getting the amount. These are done whether if you cross them minimum amount and processed generally in the first week (especially in first four days) of every month. I think you have crossed the minimum amount in this month so you will get the invoice in the next month as far my knowledge but as the Sindhu mam suggested you that you can ask Tony sir if you require them in urgent. But my advice is that there is no lot gap between the next month, serve more and get more cash in the next month itself.
