Included into VAT


You can arrange for the system to include overpayments into VAT in InvoicingSettingsInvoice group. You can activate this option by checking the Include overpayments to VAT box. In addition, you have to set a numerical series that will be used to keep a record of overpayments. You can do that in the Initial value of number line of included overpayments to VAT (VAT documents) item.


When an overpayment occurs, the system automatically creates a tax document in which the VAT amount from the amount received is stated. If such an overpayment is then deducted from the total of an issued invoice, the VAT amount recorded when the overpayment occurred is deducted too. Overpayments included into VAT and all the related documents issued can be found in InvoicingOverpaymentsIncl. to VATOverview and InvoicingOverpaymentsIncl. to VATBy groups. If you plan to use this option, we recommend that you mention it in the terms and conditions.
