errors
will
happen
from
time
to
time，
but
many
common
accounting
mistakes
can
be
oided
with
proper
planning
and
preparation.
Here
are
the
top
seven
accounting
mistakes
that
should
be
paid
more
attention
to.
（
1
）Not
knowing
your
true
cash
balance：
Due
to
things
like
automatic
payments
and
bank
charges，
money
that
appears
in
your
cash
drawer
and
your
checking
account
may
already
be
spent.
（
2
）Mistaking
profits
for
cash：
When
you
he
a
lot
of
credit
sales，
your
company
can
post
big
profits
without
seeing
any
cash.
（
3
）Paying
bills
too
soon：
If
your
vendors
give
you
thirty
days
to
pay
them，
take
it.
Unless
you
get
a
discount
for
paying
early，
paying
your
bills
only
when
they’re
dueimproves
your
company’s
cash
flow.
（
4
）oiding
book
-keeping
tasks：
Not
recording
and
posting
transactions
regularly
lees
you
with
a
mountain
of
book-keeping
to
deal
with
in
the
end.
（
5
）Paying
accidental
pidends：
Every
time
a
corporation
owner
takes
money
out
of
his
business，
it
counts
as
a
pidend.
That
can
lead
to
a
bigger
personal
income-tax
bill.
（
6
）Not
keeping
personal
finances
separate
from
business：
Mixing
up
business
and
personal
money
can
cause
bookkeeping
and
legal
problems.
（
7
）Setting
prices
too
low：
Know
your
costs
before
you
set
product
or
service
prices，
or
you
run
the
risk
of
losing
money
on
every
sale.
A
simple
break-even
analysis
can
help
you
set
prices
at
a
profitable
level.With
a
lot
of
credit
sales，
your
company
may
he
no
cash
at
hand. “破釜沉舟”出自哪次战役？（）
