Many essential records at base camp are recorded in the "Bier Book" and the "Sesh Book".
This is used to record vital information:
The record of the number of beers (and other drinks) that each person drinks from the common store in the potato hut looks like this. This is used when the treasurer does the final accounts reckoning after the end of expo.
We use this book to record where everyone spends the night. This is important because this is used to record our tax liability which is part of our camping fee for the Gasthof. We have been visited by tax inspectors in the past, so this is not just a "nice to have".
This also records the number of nights spent at the bivvy and underground camp. We use this data to help us plan the food needed up the mountain for future expeditions.
As well as the obvious need to promptly record supermarket bills and shared meals in the sesh book, and to tick off bier as it is drunk, the entries in the sesh book should be transcribed into the bank of expo every couple of days. Keeping up with this data entry saves an immense amount of time later on.

As well as writing the amounts of money in the books, printed receipts for expo expenses need to be put in the envelope in the potato hut.
Each receipt needs
Both expo communal expenses and shared group expenses should be entered into your Bank of Expo online account. When you have typed it in, make a written note "BoE done" against that line in the book. (If you don't do this the expo treasurer will have to do it. And you want to keep the expo treasurer happy don't you?)
