If you're an Admin in Cledara, you can retrieve the invoices for your Cledara subscription by going to Settings > General > Account & Billing.
There you can check the date of the last invoice and whether it has been paid or not.
To obtain a PDF copy of the invoice, click on View invoices. A pop-up window will open up your Billing history where you can download the issued invoices.
If you have more than one workspace and need assistance in retrieving your invoices, please contact support@cledara.com.
