8. Auditing of Invoices. When invoices are received they should immediately go to the purchasing agent. If there is no regularly appointed purchasing agent, or in a business like a department store where there are several buyers, the invoices should be kept by the auditor, comptroller, or chief accountant until the goods are received, when he will obtain the O. K. of the person who ordered the goods or incurred the obligation.

Pending the receipt of the goods, the invoices should be filed alphabetically, under the name of the vendor. The file may be one of the flat files which can be kept on the desk or if the number of invoices be large, a section of a vertical file drawer can be used.

When the goods have been received, which will be attested by a report in some form by the receiving clerk, the invoice is O. K.'d for quantities and prices by the buyer, and extensions are checked by the auditor or chief accountant.

9. Executing and Registering Vouchers. As soon as the invoices are audited, vouchers are executed and entered in the invoice register. Extensions are made to the proper columns, placing the accounts on the books, just as would be done if invoices were credited to accounts of the vendors in the general or purchase ledgers.

Vouchers should never be made for invoices in dispute, as to prices or on account of claims for shortage, damaged goods or other cause. Until such claims are adjusted, the invoices should be kept in a file reserved for items in suspense. When the books are closed, such items must be included under liabilities in the balance sheet. To avoid actually entering them on the books, they may be entered in the balance sheet under some such caption as "Suspense Accounts."

10. Filing Audited Vouchers. The vouchers are now ready for filing until date of payment. This does not apply if invoices are always paid as soon as audited, but in the majority of business houses at least a part of the vouchers will not be paid until the last due date; or if discounts are taken, they will be paid on the last discount date.

Some provision must be made for bringing these vouchers to notice on the date at which they should be paid. For this purpose, a "tickler" or date file is used. This consists of a file with an index of 31 numbered index sheets, intended to represent the days of the month, and sometimes a set of twelve index sheets printed with the names of the months.

The audited vouchers are filed under the date when payment is to be made, either the discount date or the last due date, by placing them back of the index sheet bearing the corresponding number. To illustrate; if an invoice is dated the 2nd of the month, and terms are 2/10, the last discount day will be the 12th, and the voucher will be filed back of the No. 12 index sheet. If payment is due in a subsequent month, the voucher is filed back of the corresponding monthly index, then on the first of the month these vouchers are distributed under the proper dates.
