inviro not the only one not paying

The debtors balance at 30/6/06 was $2.184 mil

Since that date, only $27,000 has been received

Excluding the $1.485 mil owed by Inviro, that's an extra $672,000 from other sales that the other customers are refusing to pay. Mostly this must be the "sale" to Malaysia announced in March.

Why does no-one want to pay for the stock they have taken? Is there some problem with the product that it does not work as promised?
