It has been easy to become somewhat narrow minded when thinking about APT's success, and forget they only do retail.

This paragraph from the SMH article is a stark reminder of transaction processing opportunities across a number of other very lucrative verticals:

"While the construction and retail sectors have been problem areas for late payments, the communications and professional services sectors have also seen lags in payment times":

Couple of things to consider:

The US has one of the largest construction markets globally (current value 1,231 billion)
Spending on US private construction in 2018 ~$992 billion
Australian construction market was valued at roughly ~$350 billion in 2018
Professional Services firms in the US generated $2 trillion in revenue in 2018 (Up 11% from the previous year)
Professional services market in Australia was valued at around ~$165 billion in 2018.

If QFE executes successfully, and captures even 1% of the payments associated with construction and professional services in both Australian and the US, imagine what that would mean.

Purely hypothetical of course
