We keep a plain-text ledger of transactions in ~cotech.journal~. Using the [hledger](https://hledger.org/) tool we can generate reports. A typical one is the (financial) year-by-year break down of income and expenses which we report occasionally on the [discourse forum](https://community.coops.tech/c/cotech/fund/25).
