Using Obsidian for Receipts/Confirmations?

One of my current uses for Joplin is to keep copies of receipts from things like online bill payments. I use the Firefox web clipper extension to highlight and save things like amounts and confirmation numbers. If I order something online, I also save a copy of the invoice/receipt for that order. Occasionally I might get an important e-mail and copy that as a note as well.

Does anyone use Obsidian like this currently, or have any similar workflows to share? I have several thousand notes in Joplin (previously migrated from Evernote), so I’m still trying to decide how badly I want to switch and whether I can use Obsidian for more than just regular notes.
