Here's one big implication for finance for the 21st century - switch from accrual to cash.
"Cash" accounting means you measure your profit, and reserves, by how much liquid assets you have (cash, stocks, bonds, CDs, anything that can covert to cash immediately).
"Accrual" accounting means you measure your profit, and reserve, not just by how much liquid (cash) assets you have, but also other supposedly valuable assets. Like inventory, furniture, buildings, computers, etc.
In this century, switch from accrual to cash accounting. In the last century, it made sense to say my organizaiton's furniture, inventory and computers could be sold and were worth something. Maybe they were. They aren't now.
Example: Say you sell Cabbage Patch Dolls. At the beginning of the craze, you end your fiscal year and have a bunch of dolls still in inventory. It makes sense to count them as assets, because you will sell them soon. But now the craze is over. It makes no sense to say my inventory of dolls is worth anything, because realistically I can't sell them.
Well, that's the situation with my organization's inventory, furniture, and computers. Realistically, they aren't worth anything. Keeping books based on an accrual basis looks like it artificially inflates profit and reserves. You can get into big trouble. Change accounting. What do you think?
