Scanning receipts for paperless environment

I'm using my Android device to scan receipts for warranty receipts, or for expensive stuffs. I'm uploading the receipts to Google Drive which works well, except that it's a long process to scanning each receipt. I open the Google Drive, enter the right folder, click the button for creating a new file, choose to take a new picture, take the picture, then rename the newly created file to something more fitting i.e. name of item or store name and date, and then enter my Gallery and delete the picture from the camera roll because I don't want it there. Also, if possible, I'd like to crop the image, or even stitch 2 pics together if the receipt is too long. Well, you get the picture. Is there a better way of doing this?
