Step 1: Opening an Item in Inventory Go to **Inventory** and search for the item you want to add — an oil filter, a set of brake pads, a TPMS sensor, a case of 0W16 full synthetic oil. Open the item to get to its page, which is where the add-to-order options live. If you're looking for tires, use the **Tire Catalog** instead: it searches by fitment, handles different front and rear sizes, and lets you filter by distributor. Inventory is built to hold your stock; the Tire Catalog is built to find tires. The inventory page for the item 0W16 Full Synthetic Oil, with Add to Work Order and Add to Estimate dropdowns at the top right. The Details row reads brand name Mobil 1, product code 0F16-OIL, description Mobil 1 Full Synthetic 0W1 and category PART. The Inventory table below shows location Aubin's Auto with zero On Hand, Allocated Stock and Available, and Open Orders reads No Record Found. Step 2: Adding an Item to an Existing Work Order or Estimate On the item page, open the **Add to Work Order** dropdown. You'll see **New**, **Last Opened**, and every open work order for the store you're currently in. Choose the work order you want and the item is added to it. A confirmation appears with a link straight to that order, so you can jump to it and keep building the job, or stay in Inventory and add something else. The same 0W16 Full Synthetic Oil page with the Add to Work Order dropdown open. It lists New Work Order at the top, then a Last Opened Work Order heading over WORK:47G-CU for Amy Filter and a 2024 Ford Bronco Outer Banks, then an All Work Orders heading over WORK:47G-CU and WORK:46W-RZ. Step 3: Starting a New Work Order or Estimate from Inventory If the job doesn't exist yet, choose **New** in either dropdown. The system creates the work order or estimate and puts the item on it in one step, then gives you a link to the new order. A work order you create this way behaves like any other. The next time you open the **Add to Work Order** dropdown, it appears in the list of open orders, so a second part can go onto the same job. Step 4: Knowing Where the Item Lands on the Order Each item you add from Inventory arrives in its own service group on the order. The group is named after the item's category: tires go into a group called **Tires**, and everything else goes into a group called **Parts**. This is worth knowing before you add several things at once. If you add three parts one at a time from Inventory, you'll see three separate groups on the order rather than one group holding all three. The line itself carries the item's name, price, and quantity from your inventory record. Use the drag and drop functionality to move the item into the relevant service. **How it appears when you first move the part into the work order:** The work order's service list with a group named simply Parts, marked Pending approval, reading Labor (0) Parts (1) and $0.00. It sits on its own above the separate Oil Change [Menu] group at $250.00, a Tires group at $980.00 and Shop Fees at $76.90. The search bar at the top carries Add Service, Add Tires, PartsTech, Expand All and Edit Services. Click "edit services" and use the drag and drop functionality to move the part into the oil change service: The service group Oil Change [Menu] open for editing, with a drag handle at the left of every row. Under Parts are a Filter row at 1 item and $50.00 and the moved-in 0W16 Full Synthetic Oil row, part number 0F16-OIL, at 1 item and $0.00; under Labor is a row of 2.0 hours at $100.00 totalling $200.00. The group header reads Pending approval and Labor (1) Parts (2) $250.00.
