How to link an invoice to a payment

If you would like to add a document to your transaction, e.g. an invoice, you can do so by following these steps:

• Go to the transactions tab and select a transaction. You will then see the possibility to add a PDF or an image. 
• Did you already upload an invoice that is now in your transactions? Then link your invoice to your transaction. This way, you avoid duplicating the expenses or revenues in the statistics tab.
