Invoices for all accounts are generated and issued from the Schedules module at the end of each invoicing period.

> ℹ️ **Note**
> ℹ️ 
> ℹ️ Use the <u>[Accounts Module](https://support.rubiconwater.com/help/dms/content/topics/modules/accounts/land_accountsmodule.htm)</u> to generate an invoice for a single account.

An invoice is created for each account and contains account items for any charges that are due for payment in the invoicing period. These charges include any items whose effective date falls within the invoice period, plus any left over un-invoiced items from earlier periods.

# Generate and issue all invoices for a period

## Generate Invoices

- In the [Schedules module](https://rubiconwater.atlassian.net/wiki/spaces/BNC/pages/1990001435) select the season for which to generate invoices, and choose **Invoice > Generate** from the menu.

The application collects or calculates the account items for each invoice and creates an invoice for each account that has associated account items.

## Check Invoices

You must check the invoices and make any necessary changes before you issue them to customers. You cannot make changes to an issued invoice.

- In the [Invoices module](https://rubiconwater.atlassian.net/wiki/spaces/BNC/pages/1990361182) click **Search** to open the Find Invoices screen.
- Check each invoice to ensure that the Item Details are correct. You can Delete or Modify any account items that are incorrect.

> ℹ️ **Note**
> ℹ️ 
> ℹ️ Use the <u>[Accounts Module](https://rubiconwater.atlassian.net/wiki/spaces/BNC/pages/1989935281)</u> to add new account items such as payments, adjustments and special charges. You must do this before issuing the invoices.

## Issue Invoices

You can issue invoices as soon as the invoicing period has ended. All invoices are issued together, and you cannot modify an issued invoice.

- In the [Schedules module](https://rubiconwater.atlassian.net/wiki/spaces/BNC/pages/1990001435) choose **Invoice > Issue All** from the menu and confirm that you want to issue invoices.

The application marks all the invoices as *Issued*.

# What Next?

Typically, the issued invoices are exported to an external accounting package. This process is usually configured by Rubicon to meet your specific needs. Contact Rubicon Support for more details of how the billing modules are integrated with your own invoicing processes.
