#### Issuing Credit Invoice

To issue a credit invoice, you should do the same as for custom invoice, but enter an invoice amount with negative sign. After you save the document its type will be automatically set as Credit Invoice and you will see this in the invoices list. And a credit invoice balance is shown as a negative value.

To issue a credit invoice:

1. Click the New Invoice button.
2. Fill the form that appears on the screen:
   1. Adjust the document issuing date by selecting the time and date from the relevant drop-down menus entitled as Document date. To set the current time and date, click the Now button next to these drop-down menus.
   2. Type the ID and name of the account you want to issue the credit invoice for into the relevant fields entitled as Account. Or click the Select button and select the account from the list that appears in a popup window.
   3. If an account you are issuing the credit invoice for is subject to some tax zone and tax rates are to be applied to the credit invoice total amount, then you can select the way of taxes calculation by checking or clearing the Amounts include all the taxes box:
   - If you check the Amounts include all the taxes box, then after you save the invoice, all the prices for items enlisted in the invoice will the recalculated in accordance with the corresponding tax rates and the string showing the deducted tax amount will be added to the invoice details, and the invoice total amount will stay the same. For example, if you enter two items at 100 USD each and the tax rate to be applied is 5%, then after the invoice is saved the calculation will look as follows:

   item 1 | USD 95
   item 2 | USD 95
   Tax | USD 10

   - If you leave the Amounts include all the taxes box clear, then after you save the invoice, all the prices for items enlisted in the invoice will stay the same, the string showing the calculated tax amount will be added to the invoice details, and the invoice total will be increased by the tax amount. For example, if in this case you enter two items at 100 USD each and the tax rate to be applied is 5%, then after the invoice is saved the calculation will look as follows:

   item 1 | USD 100
   item 2 | USD 100
