Best place to save supporting receipts for general journal entries

Hi jetski, 

Thanks for posting and welcome to the Community Forum. 

I understand the need to have all receipts connected to the company file. I recommend reading through the article, Working with In Tray Documents. The In Tray is a feature where you can upload documents for your file.

How you record your purchases will depend greatly on your preferences. But you can read through this article, Enter a Bill, Quote, or Order to see if this will work better for you. 

Let us know if you require any further assistance. 

Thanks,
