Award rates come from the Fair Work Ombudsman, superannuation from the ATO, and software prices from the vendor's own pricing page on the day of writing. Each post lists what it used at the bottom, with a link, so you can go and look.
Where a figure is a market range rather than a published price, it is called a range and it says so. Nothing here is rounded up to make a point, and there are no case studies, because this studio is new and does not have any. Made-up proof would be the fastest way to lose the argument these posts are making.
Prices are Australian dollars and excluding GST unless the sentence says otherwise. Every price we quote for our own work comes from the same place the pricing page reads, so the two cannot disagree.
