# Invoice fraud checks for Dynamics 365 Finance

Dynamics 365 Finance has invoice fraud checks built in. Pulsify flags changed bank details, an invalid or missing tax ID and emails that fail sender checks.

Invoice fraud checks look for fake invoices and changed bank details before money leaves your account.

## What Dynamics 365 Finance does on its own

Vendor bank account change approval, vendor change approval and duplicate number rejection.

- No ABN Lookup

## What you need in Dynamics 365 Finance

- Vendor bank account change proposal workflow feature in Feature management
- Procurement role for vendor onboarding

## Setting it up in Dynamics 365 Finance

Where to find it: Accounts payable > Setup > Accounts payable parameters > Vendor bank account approval

1. Turn on the vendor bank account change proposal feature in Feature management.
2. Set approval for create and update and pick the protected fields.
3. Create the workflow from Workflow approval for proposed vendor change.

3. It flags a tax ID that differs from the supplier record or is missing.
4. If an email fails sender checks and the sender's domain enforces it, Pulsify holds the email and warns you.
5. Each document gets one signal in the queue: Needs fix, Check or Ready.

What Pulsify does not do:

- Flags are warnings. Call the supplier on a number you already have before paying new bank details.
- Pulsify never moves money.

## Common questions

### Does Finance approve supplier bank account changes?

Yes. Turn on the vendor bank account change proposal feature and set the protected fields. Changes wait for workflow approval. The supplier callback is still a manual step.

### Is there an ABN check on the vendor?

The Microsoft help does not document an ABN Lookup check. The ABN is recorded on the vendor and used on the TPAR. Check it on the ABN register yourself.

### What is the most common invoice fraud?

A fake email asking you to update a supplier's bank details. The next real invoice is then paid to the fraudster's account.
