# Upload inventory to Meta



You need to upload a business's inventory to Meta in a catalog format — see [About Catalogs](https://www.facebook.com/business/help/890714097648074) for more information.

If a business already has a Meta catalog set up, use that catalog for WhatsApp commerce use cases. Just [connect the catalog to a WhatsApp Business account](https://www.facebook.com/business/help/158662536425974) (WABA) and the business will be able to [share products with customers](https://developers.facebook.com/documentation/business-messaging/whatsapp/catalogs/share-products).

If a business needs to create a catalog, there are two possibilities:

- Create a catalog using the [Commerce API](https://developers.facebook.com/documentation/ads-commerce/commerce-platform/catalog/get-started).
- Create a catalog using the [Meta Commerce Manager](https://business.facebook.com/commerce/).

You can only upload one catalog per WABA, but the same catalog can belong to multiple phone numbers.

## Solution partners

Solution Partners onboarding client businesses into commerce messages have the following options:

- If a client business already has and manages their own Meta catalog, they can give permission to the Solution Partner to manage their catalog — the client business controls these permissions via the [Meta Business Suite](https://business.facebook.com/) and [Meta Commerce Manager](https://business.facebook.com/commerce/). After that, the Solution Partner can [connect the WhatsApp Business account to the catalog](https://www.facebook.com/business/help/158662536425974) via WhatsApp Manager.
- If a client business doesn't have a Meta catalog, they can create and upload a new catalog under the Solution Partner's business ID.
