Light supports multiple ways to bring vendor bills into AP: uploading files, manual entry, email-to-inbox, and CSV import. All ingested bills land in the **Inbox** tab.

Navigate via Spend management → Bills.
Uploaded files run through AI extraction — see AI invoice extraction.
Good to know: If the AI extracts a PO number from the bill, Light automatically matches the bill to the corresponding open purchase order for that vendor. You'll see the PO link already filled in when you open the bill in the Inbox.
Each entity has a forwarding email address. Email a bill attachment to that address and it lands in the Inbox.
For bills without a document (or to add line-level detail), open a bill in the Inbox and edit it directly. You can also create a bill from scratch from a vendor's record.
Upload a CSV via the same Upload drawer to create multiple bills at once.
Once in the Inbox, open a bill to fill in or edit:

Line items — for each line:
When a bill is ingested, Light flags potential duplicates. The flagged bill shows a duplicate indicator and may move to the DUPLICATED state, where it can be reviewed before being kept or discarded.
Once a bill's data is complete, it moves into approval. See Bill approval.
