I thought that Khipu were primarily an accounting method similar to a abacus but with a permanent record. Tie so many knots in strings that represent placeholders. For example a khipu with six knots in the first string and two in the second would represent 26 llamas. (It was more complex than that, but that is just an example.)

I distinctly recal seeing a program where an Peruvian shepherd demonstrated his khipu accounting system and a Peruvian shopkeeper demonstrated its use as an inventory device.

Enron used a similar accounting system.
