Select your supplier and follow the steps on the *Integration Setup* screen. > [!WARNING] > **Caution:** The Add Account screen may vary depending on the supplier you select. You need your supplier account or login information. ### Integration Setup From the integration setup screen, you can map the supplier integration to ServiceTitan in three simple steps. **Step 1 - Link Vendors** 1. Select and link a *Replenishment vendor* for integration. ![Integration setup screen for linking vendors with options for electronic delivery.](https://cdn.document360.io/961862ab-d0f2-4d91-bb62-a62ee8184eff/Images/Documentation/onboarding-guide_-supply-chain-integration-for-servicetitan-roofing-customers-image-un20l476.png?sv=2026-02-06&spr=https&st=2026-11-01T17%3A49%3A48Z&se=2026-11-01T18%3A49%3A48Z&sr=c&sp=r&sig=vO%2FbZZjnno0j%2BG%2F9oTg5CJ0dmRv5DdfDg0HZ%2Bd6rz9I%3D) Vendors can only be linked if they're replenishment vendors and not used in any other active integrations. Filter results using the **Show only replenishment vendors** toggle or set vendors as replenishment in settings. For more, see [Set up vendors](/roofing/docs/set-up-vendors). 2. Review the information and click **Next**. **Step 2 - Verify Supplier Account Number** Enter your supplier credentials or, if applicable, select your preferred supplier account if you are already logged in. Keep in mind that this step might vary depending on the supplier integration you are setting up. **Step 3 - Map Account** 1. Click **Manage Accounts** to select supplier branches to map to your ServiceTitan business units. ![Integration setup screen showing steps to link vendors and manage accounts.](https://cdn.document360.io/961862ab-d0f2-4d91-bb62-a62ee8184eff/Images/Documentation/onboarding-guide_-supply-chain-integration-for-servicetitan-roofing-customers-image-9rxhb48r.png?sv=2026-02-06&spr=https&st=2026-11-01T17%3A49%3A48Z&se=2026-11-01T18%3A49%3A48Z&sr=c&sp=r&sig=vO%2FbZZjnno0j%2BG%2F9oTg5CJ0dmRv5DdfDg0HZ%2Bd6rz9I%3D) 2. On the *Manage accounts* pop-up that opens, select the accounts you want to pull costs from Pricebook, then click **Save**. ![Manage accounts interface with options to select accounts for Pricebook costs.](https://cdn.document360.io/961862ab-d0f2-4d91-bb62-a62ee8184eff/Images/Documentation/onboarding-guide_-supply-chain-integration-for-servicetitan-roofing-customers-image-ivtd9yi1.png?sv=2026-02-06&spr=https&st=2026-11-01T17%3A49%3A48Z&se=2026-11-01T18%3A49%3A48Z&sr=c&sp=r&sig=vO%2FbZZjnno0j%2BG%2F9oTg5CJ0dmRv5DdfDg0HZ%2Bd6rz9I%3D) 3. For each account, assign the appropriate Business Units. > [!TIP] > **Tip:** Use the search box to find a specific branch. 4. Select a **Primary** account as the default for purchases. > [!NOTE] > **Note:** ServiceTitan uses the primary account for customer-specific costs, catalog filtering based on branch availability and pre-populating PO fields; other accounts used in mapping will contribute to only customer-specific costs. 5. When finished, click **Activate**. Activating the vendor integration stores the mapping between ServiceTitan and your supplier. This mapping also determines the item costs in estimates. When the Business Unit is selected, ServiceTitan uses the mapping to apply region-specific pricing. As a result, estimates reflect the pricing from the specific vendor store branch linked to the business unit, which is especially useful for businesses operating across multiple regions. > [!NOTE] > **Note:** If you have multiple accounts depending on your supplier, you may be able to complete account mapping for multiple accounts. Please check out the [Multiple Accounts](/roofing/docs/set-up-multiple-account-integrations-in-a-single-vendor-s-system) article. ## Step 2: Set up your pricebook After activation, add vendor catalog items to your ServiceTitan Pricebook. This is important as it allows you to view costs, add items to estimates on mobile, and create POs. There are several ways you can add items to your Pricebook: ### Option 1: Upload Purchase History First, request your purchase history from your supplier. Once you receive it, follow the steps to upload it. 1. Go to the navigation bar and click **Pricebook.** 2. In the side menu, click **Pricebook Connect > Catalogs**. 3. Select a provider and click **Upload Purchase History.** 4. Follow the [Import Purchase History](/roofing/docs/upload-purchasing-history-from-vendor#import-purchase-history) steps. ![Instructions for importing purchase history with file upload and template download options.](https://cdn.document360.io/961862ab-d0f2-4d91-bb62-a62ee8184eff/Images/Documentation/onboarding-guide_-supply-chain-integration-for-servicetitan-roofing-customers-image-8fl761ao.png?sv=2026-02-06&spr=https&st=2026-11-01T17%3A49%3A48Z&se=2026-11-01T18%3A49%3A48Z&sr=c&sp=r&sig=vO%2FbZZjnno0j%2BG%2F9oTg5CJ0dmRv5DdfDg0HZ%2Bd6rz9I%3D) ### Option 2: Add net new items 1. Go to **Pricebook > Pricebook Connect > Catalogs**, select a catalog to browse, and view categories. > [!NOTE] > **Note:** When regionality filtering is enabled, the Catalog screen displays only items available from integrated supplier branches set in the vendor account setup. To update the branches, click **Items are filtered based on selected branches**. ![Instructions for filtering items based on selected branches during account activation process.](https://cdn.document360.io/961862ab-d0f2-4d91-bb62-a62ee8184eff/Images/Documentation/onboarding-guide_-supply-chain-integration-for-servicetitan-roofing-customers-image-eh3ig3xw.png?sv=2026-02-06&spr=https&st=2026-11-01T17%3A49%3A48Z&se=2026-11-01T18%3A49%3A48Z&sr=c&sp=r&sig=vO%2FbZZjnno0j%2BG%2F9oTg5CJ0dmRv5DdfDg0HZ%2Bd6rz9I%3D) 2. From the *Categories* list, select a category or open the category and select an item within the category. 3. From the selected category screen, you see all of the parent items by default. To see the different variants, click **Show Details** **> Variants** for more information. > [!NOTE] > **Note:** A parent item includes general product details such as manufacturer and name. A variant refers to a specific version of the item, such as a particular size or color. For example, parent: GAF Royal Sovereign, variant: GAF Royal Sovereign – Charcoal. ![GAF Royal Sovereign StainGuard shingles with a clickable option to show details.](https://cdn.document360.io/961862ab-d0f2-4d91-bb62-a62ee8184eff/Images/Documentation/onboarding-guide_-supply-chain-integration-for-servicetitan-roofing-customers-image-zsg4zld2.png?sv=2026-02-06&spr=https&st=2026-11-01T17%3A49%3A48Z&se=2026-11-01T18%3A49%3A48Z&sr=c&sp=r&sig=vO%2FbZZjnno0j%2BG%2F9oTg5CJ0dmRv5DdfDg0HZ%2Bd6rz9I%3D) 4.

You can add the selected item and manually select specific items or click **Select All** to choose all items. ![A cursor clicking the 'Select all items' button on a webpage interface.](https://cdn.document360.io/961862ab-d0f2-4d91-bb62-a62ee8184eff/Images/Documentation/onboarding-guide_-supply-chain-integration-for-servicetitan-roofing-customers-image-kag32rlq.png?sv=2026-02-06&spr=https&st=2026-11-01T17%3A49%3A48Z&se=2026-11-01T18%3A49%3A48Z&sr=c&sp=r&sig=vO%2FbZZjnno0j%2BG%2F9oTg5CJ0dmRv5DdfDg0HZ%2Bd6rz9I%3D) > [!WARNING] > **Caution:** Select **Show variant items** to view and manually choose item variants from the item list instead of parent items. 6. When done, click **Add to Pricebook**. ![A cursor clicking the 'Add to Pricebook' button on a webpage interface.](https://cdn.document360.io/961862ab-d0f2-4d91-bb62-a62ee8184eff/Images/Documentation/onboarding-guide_-supply-chain-integration-for-servicetitan-roofing-customers-image-i4d25r09.png?sv=2026-02-06&spr=https&st=2026-11-01T17%3A49%3A48Z&se=2026-11-01T18%3A49%3A48Z&sr=c&sp=r&sig=vO%2FbZZjnno0j%2BG%2F9oTg5CJ0dmRv5DdfDg0HZ%2Bd6rz9I%3D) Now you have added items to your Pricebook and can further customize them to fit your business workflows. See [Manage supplier catalog material variations in ServiceTitan](/roofing/docs/manage-supplier-catalog-material-variations-in-servicetitan) for more insight. ## Step 3: Manage your pricebook After items are mapped or added from the vendor catalog to your pricebook, let's see how you can further manage them within your Pricebook. ### Configure the cost behavior After adding supplier catalog materials to your pricebook, you can configure how the cost of a parent item is calculated based on the costs of its variations. 1. In ServiceTitan, go to the navigation bar and click **Pricebook**. 2. In the side menu, under the Pricebook section, click **Materials**. 3. Click **Settings** next to the *Edit Mode* toggle. ![Settings icon and edit mode toggle for managing columns in a user interface.](https://cdn.document360.io/961862ab-d0f2-4d91-bb62-a62ee8184eff/Images/Documentation/onboarding-guide_-supply-chain-integration-for-servicetitan-roofing-customers-image-rutrfm7t.png?sv=2026-02-06&spr=https&st=2026-11-01T17%3A49%3A48Z&se=2026-11-01T18%3A49%3A48Z&sr=c&sp=r&sig=vO%2FbZZjnno0j%2BG%2F9oTg5CJ0dmRv5DdfDg0HZ%2Bd6rz9I%3D) 4. Select the **Set cost as** option. Decide how you want to set the cost of parent items by selecting one of the below options from the cost dropdown: 1. Minimum 2. Maximum 3. Average 4. Manual ![Settings for material and equipment configuration, including cost options and display settings.](https://cdn.document360.io/961862ab-d0f2-4d91-bb62-a62ee8184eff/Images/Documentation/onboarding-guide_-supply-chain-integration-for-servicetitan-roofing-customers-image-n6m90i9q.png?sv=2026-02-06&spr=https&st=2026-11-01T17%3A49%3A48Z&se=2026-11-01T18%3A49%3A48Z&sr=c&sp=r&sig=vO%2FbZZjnno0j%2BG%2F9oTg5CJ0dmRv5DdfDg0HZ%2Bd6rz9I%3D) > [!NOTE] > **Note:** Setting the cost to Manual prevents automatic cost updates to parent items. However, selecting Maximum, Minimum, or Average will trigger automatic cost updates in the Pricebook, based on updates to the item variant costs. 5. Click **Save**. > [!TIP] > **Tip:** To configure the cost for each parent material individually, open the material, go to the Configurable Material tab, and select the desired cost behavior, Maximum, Minimum, Average, or Manual. Setting an individual cost in this manner overwrites the main setting on a per item basis. ### Configure item updates After items are mapped or added from the vendor catalog to your pricebook, item costs pull from the supplier through **Pricebook > Pricebook Connect > Updates** for you to apply. Costs update nightly. You can *Manually* update items or enable *Auto* updates in **Pricebook Connect > Updates** section. 1. On the *Updates* screen, click the **Provider** dropdown and select the catalog you want to view updates for. 2. Click **Auto** ![](https://cdn.document360.io/961862ab-d0f2-4d91-bb62-a62ee8184eff/Images/Documentation/icon-gnav-settings-inactive.png?sv=2026-02-06&spr=https&st=2026-11-01T17%3A49%3A48Z&se=2026-11-01T18%3A49%3A48Z&sr=c&sp=r&sig=vO%2FbZZjnno0j%2BG%2F9oTg5CJ0dmRv5DdfDg0HZ%2Bd6rz9I%3D) to manage update settings. 3. Select **Auto Update** for fields you want to update automatically and click **Save** to apply changes. > [!TIP] > **Tip:** We recommend turning on Auto Update for costs to ensure accurate and up-to-date information. ![Settings for managing roofing vendor details including cost, hours, and media assets.](https://cdn.document360.io/961862ab-d0f2-4d91-bb62-a62ee8184eff/Images/Documentation/onboarding-guide_-supply-chain-integration-for-servicetitan-roofing-customers-image-opy3prev.png?sv=2026-02-06&spr=https&st=2026-11-01T17%3A49%3A48Z&se=2026-11-01T18%3A49%3A48Z&sr=c&sp=r&sig=vO%2FbZZjnno0j%2BG%2F9oTg5CJ0dmRv5DdfDg0HZ%2Bd6rz9I%3D) 4. You can view automatic and manual updates/dismissals in the *History Log*.
