Every supplier bill is checked against the last 90 days, an unusual payment says what's usual, and a payment to new bank details waits for someone else to confirm.

#### The same $3,480, twice

Pixelwright QA billed Alder & Wren $3,480 as PW-2207. A week later a second bill arrived as pw 2207, same amount, due a week later. Pay both and the money is simply gone twice.

#### Where the money goes, and whether it already went

Recorded on the demo studio's bills and payments.

1. **The bill never sets where to pay** (Bills to pay): Open the bill: where to pay comes from the supplier's contact card, never from the bill, so a PDF with new bank details can't redirect the money on its own.
2. **Ask whether it's a duplicate** ("Is the Pixelwright QA bill pw 2207 a duplicate?"): The check catches the same number written differently, the same amount from that supplier within 90 days, and money already sent to them for it.
3. **See what matched** (): Both bills side by side: PW-2207 and pw 2207, $3,480 each, both still open. Whoever holds the right to decide marks it a duplicate, which rejects the new bill and keeps both papers.

#### What Orla does

- Checks each bill against the supplier's last 90 days, and against money already sent them.
- Explains a payment that doesn't look like your usual one.
- Holds a payment to bank details you've never paid until a second person confirms.

#### What stays with you

- Decide whether a flagged bill is a duplicate.
- Call the supplier on a number you already had, and confirm.
- Sign the payment under your approval rule.

#### What Orla does not do here

- Hold a payment on a manual bank account. There it's a warning line: the hold works where Orla sends or drafts the money (a wallet, PayPal, a connected bank).
- Change a supplier's bank details because a message asked it to.
- Decide a duplicate for you, or block an unusual payment on its own.

The duplicate check is rolling out. The hold on new bank details is on in every space. Receiving bills by email is part of the paid plans.

#### Questions

##### What are some examples of vendor fraud?

The two we see most: the same bill sent twice, and a real-looking bill asking you to pay new bank details. The first is caught by the duplicate check; the second by the hold on details you've never paid.

##### How do you know if a vendor is scamming you?

New bank details, urgency and an unfamiliar sender usually arrive together. Orla never takes bank details from a PDF or an email, holds payment to new details until someone else confirms, and keeps unknown senders in quarantine.

##### Does Orla block a payment that looks unusual?

No. It explains it, with the amount you usually pay that supplier, so the signer decides knowing it. What waits for a second person is a payment to new bank details.

##### Can the assistant change a supplier's bank details?

No. Bank details, tax ids and the trusted flag never change from words, and changing a known supplier's details asks who you are.
