I'm reading all these comments about the bar through translation. So maybe I have it wrong. To me it seems that the situation your in, is caused by the lab just wanting the situation to stay as it is. How many club mate bottle have been drunk since the lab opened, multiply that by 7 crowns a bottle. Why not ask the distributor how many he has delivered? Now you also get an extra crown per bottle. Where are all the projects created from the brmbar?  it might just be that all the profit has been drunk and eaten over time... Its only really in the last months that you have started to have some sort of accounting system that functions. I also don't really understand why you have a system where people can bring their own product they buy into the lab...you have enough people that use the space to get distributors to bring product. i don't understand why people need to credit their account, why not just pay in cash as you buy the products. So much complexity is only going to create creative accounting. best run the bar like a business, and work out how to manage the situation with an accountant.  growing pains that need to be solved..I tried to bring product into the space, and it had to be brought to the attention of every member...
