Is that a standing corporation? As in stationary? It should be stationery, as in:
Middle English staciouner, a bookseller, from Medieval Latin statinrius, shopkeeper (as against a peddler), probably from Latin stati, statin-, place of business. (http://www.bartleby.com/61/92/S0719200.html)

A frequent mistake, almost as frequent as spelling seperate, rather than separate. Latin separare, to divide (no source, just my memory).

Sometimes it is easier to look in from the outside. My native language is German.
