I am a silent observer on this list but hope I can throw some thoughts in.
Those in a position to loan Makerspace startup funds should make that interest free loan to Makerspace Society. Those funds are pooled and used by Makerspace Society for base expenses.
As memberships grows, it will begin covering fully the base expenses. When this happens loans can start being paid back either monthly or in larger chunks by agreement by the pool of people who provided startup loans
Everyone’s membership price remains consistent across all members; new, old, made a loan, did not make a loan. This means if I loan $1000 I am paying $100 Keyholder price from the start - $1100. I pay $100 every month. When Makerspace is able to start returning my loan I continue to pay $100 membership completely separate from the loan repayments.
It seems strange to pay a $100 membership and be immediately refunded by the amount of the loan repayment. However, it is not a refund, it is a repayment, and your books need to keep the membership income separate from the loans.
Last thing. A detailed cash flow will also you to get your burn rate to determine your runway and estimate time to break even. You also need to be able to project forward financial successes and failures as they happen. It can be the difference of “holy shit we are in trouble” and “Hmm this could be a problem four months from now, lets think about a solution”.
My 2 cents. Please comment and let everyone know thoughts.
