We have created a simple expense claims mashup using Google Docs and Spreadsheet and PayPal. We allowed the employee to submit expense claims through a spreadsheet and a word processor document with attached scans of expense receipts. The expense claim is then approved by his or her immediate manager and placed into an approved-claims folder. At periodic intervals, we use a script to extract the contents of the claims spreadsheet and archive the receipts documents into a PDF format and save them into the mashup database. At the end of the month, we use the information in the database to send mass payments to all employees through PayPal.
