I've been experimenting with using tesseract to get information out of scanned tutorial roll sheets, with surprising success. If you ask it for tsv or hocr output, it will give you a bounding box for each word. To extract a student's attendance information, I grep the tsv files for a student ID number or name, get the y position with sed, and combine slices of the page images with Image Magick (in my case I want to see all the handwritten ticks and numbers). You might be able to do something similar looking for numbers on the same line as key words like "Total" or "apples" or whatever. Some of your success will depend on how well you scan the receipts.
