Actually I've been doing a little research on the Internet. I'm always
willing to learn.

This is interesting. Because following my mini-rant (and I confess that
was what it amounted to, and I apologize to the list for that) I've
received at least two e-mails exclaiming my ignorance and, in effect,
telling me to go read a book. But you tell me not to do it -- that
you're not supposed to try to reflect current valuation -- while Mr. Uhl
patiently explained to me how you go about doing it. So it appears that
there isn't exactly a broad concensus on this list. FWIW, my surfing
research reveals that you are entirely correct -- at least with respect
to business accounting. And keeping your investments at book-value has
the advantage of making your tax situation a lot clearer as well as
reinforcing the fact that you don't have a profit until you have the
cash. Personally, I find the whole business of creating faux
transactions to and from ersatz gains/loss accounts a pointless exercise.

I think here we need to distinguish between the *philosophy* of DE --
that money has to come from somewhere well-defined and go somewhere
well-defined -- and the mechanics of DE -- which are entirely about
guarding against math errors. For instance, one reason for the business
of debits and credits is a relic from manual arithmetic where it was
realized that subtraction was more error-prone than addition.
Personally, I find it a lot easier to think in terms of adding to this
account and subtracting from that account than trying to keep straight
where the debits and credits go. YMMV.

Theoretically, anyway. In reality there's no point for me to itemize
because I don't have enough deductions.

This is all, true. But the fact is that *both* pictures are important
and relevant. Either one by itself is incomplete. And it's more than
just the tax situation; the difference between accrual and cash
accounting is solvency vs. liquidity. Solvency is an important measure,
but it's not one that you would hope to have to test. Solvency is the
long run but it's the short run of liquidity that pays the mortgage and
buys groceries. Liquidity tells me how I'm doing this month and solvency
tells me how I'm doing this year.

Can you do the above in one transaction with splits? The way accounts
payable would work in a non-business situation is unclear from the help
files.

FWIW, I'm not the only one questioning some accepted accounting
practices. See:

But my point really isn't to question the way accounting is done in
business. And I'm sure that gnucash is a fine example of a program
designed to work the way a business accountant would want it to work.
My focus here is on personal finances and the utility of a program like
gnucash to help you effectively manage those finances. The formalism of
DE as presented in the interface is, on the one hand, unnecessarily
confusing overkill, while on the other hand, requiring you to jump
through the hoops to represent your financial reality in a useful way.
What I'm looking for here is a tool which actually *helps* you deal with
the dual perspectives of solvency and liquidity -- net worth and cash
flow -- in a relatively straight-forward manner. This tool should not
only accurately track accounts, but include the budget planning tools of
a spreadsheet.
Let me give you another example of how the DE accrual paradigm makes
life (slightly) more inconvenient. Not all transactions with tax
consequences involve incomes or expenses; events like investing in an
IRA are clearly transfers between asset accounts, yet these events have
tax benefits. Currently gnucash is unable to export those those
transactions in a TXF file because you can only tag income and expense
accounts for tax lines. It's really the same problem as the medical bill
I was tallking about earlier; a liability is just a negative asset after
all. So if you could just tag those transactions with a tax "category"
you would have no need to juggle between real and fake expense accounts.
There's a relatively simple fix for the asset appreciation problem as
well. The Finance Quote module can display today's price for market
securities. Purely for display purposes, why couldn't the account ledger
for a stock display columns for the current price and market value? No
need to screw around with "unrealized" gains and losses -- after all
they're "UNREALized" -- just tell me what they're worth today. You might
even be able to do the same thing for vehicles if you could figure out a
way to automatically hook into Kelly Blue Book.
Finally, another thing I would like to see is the ability to have the
components of a split transactions have different dates associated with
them. The date you wrote the check, the date it posted to the credit
card account, and finally the date it cleared your bank. It would make
reconciling statements easier.
