# Find vendor bill discrepancies with 3-Way Matching

## Overview

3-Way Matching (3WM) is an automated system that checks your vendor bills against receipts and purchase orders and flags discrepancies between all three documents. This ensures you're not missing important errors that could impact your financials.

3. For each kind of discrepancy, select **Show all discrepancies** or **Create custom threshold**.
4. For **Create custom threshold**, select dollar amount, quantity amount, or percentage amount and enter in the value.
5. When finished, click **Save Threshold**. ![Settings for identifying discrepancies in total amount and item quantity thresholds.](https://cdn.document360.io/961862ab-d0f2-4d91-bb62-a62ee8184eff/Images/Documentation/find-vendor-bill-discrepancies-with-3-way-matching-image-62jgzth5.jpg)
6. (Optional) If you'd like to compare line items on the PO, receipt, and bill to identify discrepancies, click **Line Item Discrepancy** to enable it.

> [!NOTE]

## Review and resolve discrepancies

To see actionable discrepancies:

1. Go to the navigation bar and click **Accounting ![](https://cdn.document360.io/961862ab-d0f2-4d91-bb62-a62ee8184eff/Images/Documentation/find-vendor-bill-discrepancies-with-3-way-matching-image-2ab94d54.png)**.
2. In the side panel, go to **Accounts Payable** **>** **Bills**.
3. Under the *Needs Review* tab, find a Vendor Bill that has a discrepancy flag listed under the *Bill No.* column.
4. Click the discrepancy flag to see a summary of the found discrepancies. ![Table displaying discrepancies in unit costs and subtotal amounts for various suppliers.](https://cdn.document360.io/961862ab-d0f2-4d91-bb62-a62ee8184eff/Images/Documentation/find-vendor-bill-discrepancies-with-3-way-matching-image-qmytfinh.jpg)
5. To see individual discrepancies, click the **Bill No.**
6. Click each discrepancy flag to display a tooltip that explains what isn't matching between the vendor bill, PO, and receipt. ![Discrepancy noted for Template Item Material 2 in billing and purchase order.](https://cdn.document360.io/961862ab-d0f2-4d91-bb62-a62ee8184eff/Images/Documentation/find-vendor-bill-discrepancies-with-3-way-matching-image-92x2pkdz.jpg)
7. Edit the bill, PO, and receipt as needed. The *Bill No.* discrepancy flag automatically updates to *No discrepancies identified* once every discrepancy is resolved.
8. When finished, [reconcile the bill](/v1/docs/reconcile-bills).

> [!NOTE]
> **Note:** If you reconcile a bill that still has discrepancies that 3-Way Matching found, you are prompted to confirm your choice. The bill is then reconciled and the discrepancies will remain flagged on the bill for any future audits.
