Hi,
I'm trying to get Ledger to automatically work out UK VAT (tax at 20%) on a
sales invoice; it seems crazy for me to have to calculate and enter this by
hand every time.
First I've tried using automated transaction amount multipliers:
= expr true
Liabilities:VAT 0.2
Assets:Accounts Receivable -1.2
08/07/2011 Invoice
Income:Sales £1000
According to the doc
http://ledger-cli.org/3.0/doc/ledger3.html#Amount-multipliers this should
be equivalent to:
08/07/2011 Invoice
Income:Sales £100
Liabilities:VAT £20
Assets:Accounts Receivable -£120
But instead I get an error:
johnpc$ ledger -f test.ldg reg -E
While parsing file "/home/john/Documents/test.ldg", line 6:
While balancing transaction from "/home/john/Documents/test.ldg", lines 5-6:
> 08/07/2011 Invoice
> Income:Sales £100
Unbalanced remainder is:
£100
Amount to balance against:
£100
Error: Transaction does not balance
johnpc$
With debug, it seems that the amount multipliers are being treated as
simple values rather than £s, and so the transaction doesn't balance.
johnpc$ ledger --debug textual.parse -f test.ldg reg -E

I've also tried value expressions which seem like they ought to be powerful
enough to help me do this, but the docs don't explain it very clearly and
I'm just stabbing in the dark. It feels like there's a value expression
party that I've not been invited to. For example the value expression in
here evaluates to zero:
08/07/2011 Invoice
Income:Sales £100
Liabilities:VAT (amount * 0.2)
Assets:Accounts Receivable
johnpc$ ledger -f test.ldg reg -E
08/07/11 Invoice Income:Sales £100.00
> £100.00
Liabilities:VAT 0
> £100.00
Ass:Accounts Receivable £-100.00
> 0
johnpc$
When I first started reading about ledger; it seemed like exactly what I
wanted. But now I'm nervous about switching my accounting system. Too much
of it seems like a black art. I'm wondering if beancount or hlledger would
be better at this sort of thing, or better documented?
Any solutions or advice would be most welcome.
Thanks in advance,
John
