Yes he has just activated his ABN (it was inactive) We used a template from the internet for the invoice and DH had to ask what the pay rate was (which should have been discussed and agreed upon in the first place IMO). Apparently it was $22 per hour. Dh was not very happy. And then the guy told him that $18.75 was actually the minimum he could have paid him, so it was like he was doing him a favor.
I was under the assumption that when working with your own ABN you are paid more because you need to take out your own tax, super, annual etc. Think this guy is a bit dodgy. DH isn't going to do anymore work with him.
