## Understand replacement part match types

When Atlas returns a list of compatible replacement parts, each part displays a match type that tells you whether it's linked to your Pricebook or a vendor catalog. The match type determines which actions you can take with the part.

**Matched Pricebook item:** The replacement part is matched to a material in your Pricebook. You can add the part to an invoice, an estimate, or a job note.

![Details of a matched pricebook item for Lennox blower motor from Johnstone.](https://cdn.document360.io/961862ab-d0f2-4d91-bb62-a62ee8184eff/Images/Documentation/use-atlas-to-find-replacement-parts-with-field-pro-in-mobile---replaced-on-thu-apr-23-2026-image-p8vb3jtd.jpg)

> [!NOTE]
> **Note:** The option to add a part to an estimate or invoice is available only when all of the following conditions are met:
> 
> - An estimate for the job exists (for estimates) or an invoice for the job exists (for invoices).
> - You have permission to edit estimates or invoices.
> - The part has a matched Pricebook material.

**Matched Vendor item:** The replacement part is matched to an item in a vendor catalog, but that item is not in your Pricebook. Because the item isn't in your Pricebook, it can only be added to a job note. To add it to an invoice or estimate, the vendor item must first be added to your Pricebook by your office.

![Matched vendor item details including part number and vendor name for Lennox product.](https://cdn.document360.io/961862ab-d0f2-4d91-bb62-a62ee8184eff/Images/Documentation/use-atlas-to-find-replacement-parts-with-field-pro-in-mobile---replaced-on-thu-apr-23-2026-image-znqvypyk.jpg)

**No Match in Pricebook:** Atlas was not able to match the replacement part to a Pricebook material or a vendor catalog item. The part can only be added to a job note. You can still use the part details displayed in Atlas to source the part on your own.

![Lennox product with a note stating no match found in the pricebook.](https://cdn.document360.io/961862ab-d0f2-4d91-bb62-a62ee8184eff/Images/Documentation/use-atlas-to-find-replacement-parts-with-field-pro-in-mobile---replaced-on-thu-apr-23-2026-image-9jcutivr.jpg)
