The following accounts are particularly important for Invoice Verification:

There is a separate account in the sub-ledger for each vendor to which the system posts all amounts concerning this vendor. Making a posting to the vendor account is not the same as making a payment; payment is only made when the Financial Accounting department posts the vendor's payment to a bank account.

In the R/3 System, you do not set up a separate account for each material. Instead, different materials with similar features are grouped together in a common account (for example, raw materials: acids). The account relevant for a material is defined in the material master record when a material is created.

The system only posts to the stock account when a price difference occurs for an invoice.

The GR/IR clearing account is an "intermediate" account between the stock account and the vendor account. At goods receipt, the net invoice amount expected is posted to the stock account. The offsetting entry is posted to the GR/IR clearing account. This posting is then cleared by an offsetting entry on the vendor account at invoice receipt.

The system makes postings to special tax accounts when invoices include tax.

Price differences have to be posted to a price difference account if there are price differences in an invoice and when invoices are posted net and no posting can be made to the stock account.

When you post an invoice net, the cash discount amount is taken into account in the invoice, it reduces the value of the items; the offsetting posting is made to the cash discount clearing account, which is then cleared when payment is made.

The stock account is debited with the planned delivery costs at goods receipt; the system makes the offsetting posting to a freight clearing account. This posting is then cleared by an offsetting entry to the vendor account at invoice receipt.
