Instead of chasing PDFs over email, you can hand a vendor one link. They fill in their invoice, and it files itself into your Bills inbox. No account, nothing to install on their side.
Step 1: Open Bills
Sign in and go to Bills.
Step 2: Find your invoice-me link
Look for the Your invoice-me link panel near the top. It explains: "Send this to a vendor. They fill in their invoice and it lands here automatically."
Step 3: Copy the link
Click Copy next to the link field. The button changes to Copied to confirm.
Step 4: Send it to the vendor
Paste the link into an email or message to your vendor. The same link works for every vendor and doesn't expire.
Step 5: The vendor fills in their invoice
When they open the link the Bill-To is locked to you, so the invoice can only ever be addressed to your account.
Step 6: Find new bills
A bill from a vendor you've accepted before goes straight to Outstanding. A first-time vendor lands in the Needs review tray for you to accept.
