How Do I Best
Deal With Supplier Invoices That Come In Late?
The differences between closing off supplier
accounts (creditors) a week or two after customer accounts
(debtors) represents a "classic" problem. One practical solution is
to confirm pricing for stock on purchase orders so that at least
the inventory side of the issue can be resolved. The purchase order
can be delivered on stock receipt/delivery docket, and then the
details checked/edited later on when the paperwork is added.
Adjustments can be made for additional freight charges and so forth
by editing the transaction's total in supplier entries. It is not
uncommon to take delivery of the stock and place something like
"pending" in the reference field. The actual amount is confirmed
when the supplier invoice arrives and the supplier invoice number
is then placed in the reference field. This works fine, on
condition that you generally know what your inventory is going to
cost you at the time of ordering, rather than getting told after
it.
The above scenario doesn't work for disorganised
companies or where importing is involved or there is a significant
variable freight portion and there is some intention of factoring
this into the invoice price. One solution is to still print your
stock quantity report as normal at the end of the month, then at
the time of closing off the creditors ledger, print a sales report.
You'll find a cost of sales figure on this report. This should also
be taken into account as part of your general stock journal at the
end of the month.
Option three is to enforce the rule that all
stock adjustments must go through a transaction. For example, you
write a zero value invoice to yourself that lists all stock that
has been written-off, errors due to stock takes, etc. This amount
will be picked up on your sales report and you can print sales
reports and look at cost of sales, etc., In place of the stock
quantity report. This option has two potential problems:
-
It assumes that users will follow such
procedures.
-
It may not take into account alterations in
re-valuing/costing of stock, unless all stock in the system is
strictly being average costed. If a and b aren't followed, you'll
get "drift" between your general ledger inventory and your stock
inventory valuation.
