Makes perfect sense to me Mary...good observation/hypothesis. Just ran a couple of #s on past fiscal year AR...looks like it has risen by an avg of $620K/qtr...which would mean that the balance of the $1.4M/qtr in sales ($780K) was more than likely from the Fleetsafer sales you referenced.
AR per Quarter...
Qtr #1 5,892M
Qtr #2 6,576M
Qtr #3 7,163M
Qtr #4 7,754M
