Up to 100 invoices for MIQ stays will be referred to a debt collection agency this week

Debt recovery action isn't considered until invoices are 90 days overdue.

As at April 30, 291 invoices were in that category, with a value of nearly 910-thousand-dollars.

It's unclear how much these bills represents.

Just over 13-thousand invoices had been issued for all MIQ stays as at May 9 - worth 60.8 million-dollars.

Of this, 38.3-million has been paid, and another 16.4-million isn't due yet.
