%% @doc Amazon Web Services Invoice Configuration
%%
%% You can use Amazon Web Services Invoice Configuration APIs to
%% programmatically create, update, delete, get, and list invoice units.
%%
%% You can also programmatically fetch the information of the invoice
%% receiver. For example, business legal name, address, and invoicing
%% contacts.
%%
%% You can use Amazon Web Services Invoice Configuration to receive separate
%% Amazon Web Services invoices based your organizational needs. By using
%% Amazon Web Services Invoice Configuration, you can configure invoice units
%% that are groups of Amazon Web Services accounts that represent your
%% business entities, and receive separate invoices for each business entity.
%% You can also assign a unique member or payer account as the invoice
%% receiver for each invoice unit. As you create new accounts within your
%% Organizations using Amazon Web Services Invoice Configuration APIs, you
%% can automate the creation of new invoice units and subsequently automate
%% the addition of new accounts to your invoice units.
%%
%% Amazon Web Services Procurement Portal Preferences
%%
%% You can use Amazon Web Services Procurement Portal Preferences APIs to
%% programmatically create, update, delete, get, and list procurement portal
%% connections and e-invoice delivery settings. You can also programmatically
%% fetch and modify the status of procurement portal configurations. For
%% example, SAP Business Network or Coupa connections, configure e-invoice
%% delivery and purchase order retrieval features.
%%
%% You can use Amazon Web Services Procurement Portal Preferences to connect
%% e-invoice delivery to your procurement portals based on your
%% organizational needs. By using Amazon Web Services Procurement Portal
%% Preferences, you can configure connections to SAP Business Network and
%% Coupa procurement portals that retrieve purchase orders and deliver Amazon
%% Web Services invoices on the same day they are generated. You can also set
%% up testing environments to validate invoice delivery without affecting
%% live transactions, and manage contact information for portal setup and
%% support.
%%
%% Administrative users should understand that billing read-only policies
%% will show all procurement portal connection details. Review your IAM
%% policies to ensure appropriate access controls are in place for
%% procurement portal preferences.
%%
%% Amazon Web Services Invoice Management
%%
%% You can use Amazon Web Services Invoice Management APIs to
%% programmatically list invoice summaries and get invoice documents. You can
%% also programmatically fetch invoice documents with S3 pre-signed URLs.
%%
%% You can use Amazon Web Services Invoice Management to access invoice
%% information based on your organizational needs. By using Amazon Web
%% Services Invoice Management, you can retrieve paginated lists of invoice
%% summaries that include invoice metadata such as invoice IDs, amounts, and
%% currencies without downloading documents. You can also download invoice
%% documents in PDF format using S3 pre-signed URLs with built-in expiration.
%% As you manage invoices across your organization using Amazon Web Services
%% Invoice Management APIs, you can create invoice retrieval processes and
%% integrate invoice data into your financial systems.
%%
%% Service endpoint
%%
%% You can use the following endpoints for Amazon Web Services Invoice
%% Configuration, Amazon Web Services Procurement Portal Preferences, and
%% Amazon Web Services Invoice Management:
%%
%% `https://invoicing.us-east-1.api.aws'
