The funding of Bill Express has always been a bit exotic, which may be fine.Take this example from the 2007 profit."The company has a strategy of leveraging its intellectual property assets by licensing them to other parties who can recognise their benefits. The company has consistently received significant income from these activities of approximately $10 million in each of the last two years. The company expects to continue to receive significant licence fees in the current year.  "The company receives significant licence, access and hosting fee income on an ongoing basis from a third party which is experiencing significant growth.  "As part of this arrangement the company has acquired fully insured receivables of approximately $49.5 million. This has been a significant factor behind the increase in the company's debt obligations of $38.2 million."
