A service charge adds a percentage to an estimate or work order. Set it up alongside automatic shop fees on the **Shop Fees** settings page. ## Before you start Open [**Settings → Organization → Shop Fees**](https://dealers.tiretutor.com/settings/organization/shop-fees). The page shows one form per shop, titled with the shop's name. Each form holds four sections: * **Automatic Tire Shop Fee**: a fee on service groups that include a tire. * **Automatic General Shop Fee**: a fee on service groups without a tire. * **Total Fee Cap**: a limit on the total of the two automatic shop fees. * **Service Charge**: a percentage on the order's included items. The **Total Fee Cap** does not limit **Service Charge**. Shop Fees form for Aubin's Auto with four sections: Automatic Tire Shop Fee and Automatic General Shop Fee turned on with a $10.00 fee each, Total Fee Cap turned off, and Service Charge turned on at 3%, with Reset and Save buttons. ## Set automatic shop fees Turn on **Automatic Tire Shop Fee** or **Automatic General Shop Fee** to show its controls. | Control | What to set | | - | - | | **Fee** | The percentage or flat amount | | **%** / **\$** toggle | Percentage or flat fee | | **Fee Cap** | An optional maximum for this fee within each service group; turn on the switch to enter it | | **Fee Categories** | **Tires**, **Parts**, or **Labor** items to include in the calculation | The percentage uses the included items' prices after item discounts and before tax, while a flat fee applies once per included line item. Select **Save** to apply the settings. Select **Reset** to discard unsaved changes. **Automatic General Shop Fee** appears as **Service Shop Fee** on the order. ## Turn on a service charge **When:** You want TireTutor to calculate a service charge for a shop. Open [**Settings → Organization → Shop Fees**](https://dealers.tiretutor.com/settings/organization/shop-fees). Find the form titled with the shop's name. Scroll to the **Service Charge** section at the bottom. Turn on the **Service Charge** toggle. The **Fee Amount** section appears. Enter the percentage in **Fee**. For example, `3` means 3%. Select **Save**. To discard unsaved changes instead, select **Reset**. TireTutor shows **Shop fee settings have been successfully saved**. Review **Service Charge** in an estimate's **Shop Fees** section. ## How TireTutor applies the charge * The service charge covers included tires, parts, labor, fixed service fees, warranty items, and state tire tax items. * The percentage applies to each included item's price after item discounts and before tax. * The order's **Shop Fees** section lists the charge as **Service Charge**. The payment summary adds it to the **Shop Fees** total. * Tax on the service charge follows your shop's tax settings for shop fees and the order's tax exemptions. * Order-level fee exclusions can remove the service charge. ## Adjust the charge on one order **When:** An estimate or editable work order needs a different service charge from the shop setting. In the order's **Shop Fees** section, select the pencil icon. Its tooltip reads **Edit**. On the **Service Charge** row, check the box in the **CUSTOMIZE** column. **Calculated Value** under **PRICE** changes to a field. Shop Fees section of a work order in edit mode, with DESCRIPTION, CUSTOMIZE, and PRICE columns, rows for Service Shop Fee, Service Charge, and Tire Shop Fee each showing an empty CUSTOMIZE checkbox and Calculated Value, and Cancel and Save buttons. Enter the amount in the **PRICE** field. A custom row needs a price. Select **Save**. To discard the edits instead, select **Cancel**. The **Service Charge** row shows a check mark under **CUSTOM**. TireTutor keeps the custom amount when it recalculates the order. A work order converted from an estimate keeps the estimate's custom shop fees. ## Change or turn off the charge Open the shop's form on **Shop Fees**. Change **Fee**, or turn off the **Service Charge** toggle. Select **Save**. Changes can affect existing estimates and editable work orders when TireTutor recalculates their totals. Completed work orders keep their saved totals, and TireTutor preserves custom amounts on individual orders. ## Where the charge appears in Square For an itemized Square order, TireTutor groups shop fees, including the service charge, into **Shop Supplies Fee**. A partial payment link shows one line instead of the itemized order: **Partial payment for** followed by the order number. ## Refunds Enter the total refund in **Refund Amount**, including any service charge you intend to return. TireTutor does not automatically add the service charge to that amount. See [Issue a refund](/dealers/pos/taking-payments#issue-a-refund). ## Still need help?
