Accounting For Software Engineers

The difference between accountants and software engineers, when it comes to accounting systems, is about what we primarily care about. Accountants care about meaning: is the quick ratio in good shape? Is income growing at an expected rate? How do we deal with an upcoming expense? Software engineers care about: will we properly move money around so that the balances are correct given certain latency, concurrency, etc.? Do we have the information required to generate the Income Statement? How do we represent a credit memo?
