Small and big don't always go well together

I've been reviewing my working relationships recently and noticed one or two things which might be hypotheses.

1. The length of time that organisations take to pay their suppliers increases with the size of the organisation.
2. Cash flow can be a driver for organisations to become bigger.
3. Cash flow can be one of the biggest problems for growing organisations.
4. Larger organisations may be missing out on valuable flexible resources as smaller suppliers decide not to work for them.
5. Freelance work has many rewards, but worry-free cash flow does not appear to be one of them.
6. Organisations that do pay on time are wonderful. Thank you!
