Shopware AutoInvoice works immediately after installation and activation of the plugin and sends invoices for all new orders that reach the payment status "Completely paid".
If you would like to configure the plugin differently, please follow the following articles for configuration:
General Settings
Brief explanation of the plugin's basic settings
This article describes the setup of asynchronous order data processing. This is required if you want to import orders from third-party plugins, such as Magnalister, or if certain payment provider plugins are not supported by AutoInvoice. This applies, for example, to: Paypal Plus, SOFORT Transfer.

FAQ
Can the invoice be sent separately for certain payment methods?
Create a new order status using the instructions ('Creating a status' and 'Provide status name in the backend') at:
https://docs.shopware.com/en/shopware-5-en/tutorials-and-faq/create-new-order-and-payment-status
Then add this new order status to "Create invoice at order status" and use it exclusively for the desired payment method. As soon as you change the respective order to this status, the invoice should be sent.
How could you re-export already exported documents?
In the database table 's_order_documents_attributes', set 'fgits_autoinvoice_exported' to 0 for all rows. Then re-export the invoices.
