Create & Manage Purchase Orders

Create a purchase order

a. Go to Inventory > Purchase Orders. Click Create New.

b. Enter the job number, business unit, vendor, order type, and technician. Set the inventory location, ship-to address, and required-by date.

c. Add items using item code, description, or vendor part number. Set quantities and costs. Click Create.

⚠︎ PO Approval Tiers are configured, users whose purchase order exceeds their assigned tier limit must click Submit for Approval instead of creating the PO directly. The request remains in a Pending status under the Requests tab until an authorized approver approves or rejects it. Once approved, the system generates a PO number and moves it to the Pending tab as an active purchase order.

⚠︎ If the PO is created from a project, the PO's business unit must match one of the project's assigned business units.

Create purchase orders

Send a purchase order to a vendor

a. Open the PO from the Pending tab. From the Send As dropdown, choose PDF, XLS, or electronic delivery (for vendors with Full Procurement Integration).

⚠︎ Electronic delivery is only available for vendors set up with the Full Procurement Integration (P2P). For all other vendors, use PDF or XLS.

b. To send in bulk, select multiple POs from the Pending tab and click Send PO. Choose the format and recipients for each vendor.

Send purchase orders to vendors

Receive items from a purchase order

⚠︎ Inventory quantity does not increase until the Receipt is posted. If techs are selling parts before the Receipt is recorded, you will get negative inventory balances.

a. Open the PO from the Sent tab. Click Receive to record the shipment. Enter the quantities received for each item.

b. For partial shipments, receive only the items that arrived. The PO moves to Partially Received status until all items are fulfilled.

c. When items are received, a Receipt is created. Depending on your settings, a Bill may be automatically created at the same time. If "Automatically create bill when PO is received" is disabled, you will need to create the Bill separately when the vendor invoice arrives.

⚠︎ A wrong price on the vendor Bill permanently alters the Weighted Average Cost (WAC) for that SKU. Corrective paths include editing the bill cost directly or manually updating the average cost in the Pricebook. Double-check vendor pricing before posting.

Compliance & Vendor Warranties

Track refrigerant cylinders for EPA compliance

Set up refrigerant tracking

a. Create specific pricebook material items for each refrigerant type your technicians handle. Set accurate costs and assign them to a dedicated "Refrigerants" subcategory.

b. To track cylinder serial numbers, you can create a "Refrigerant Usage Log" form with fields for refrigerant type, quantity, cylinder serial number, and a photo of the cylinder label. Set the form trigger to fire on HVAC job types.

c. Set up a "Task Used" alert for your refrigerant pricebook items. Route the alert to your Safety Officer or Operations Manager.

⚠︎ If using the form-based approach, ensure the form is assigned to Jobs (not just Locations) — forms assigned only to Locations do not appear in the Form Submissions report, which breaks your audit trail.

Generate EPA-ready refrigerant usage reports

a. Go to Reports > Create Report, select the Invoice Items template, and filter by your Refrigerants subcategory. Include these columns: Item Name, Quantity, Customer Name, Location Address, Job Date, and Technician.

b. Compare ServiceTitan usage records to physical cylinder inventory regularly to ensure reporting accuracy for EPA audits.

File a warranty claim with a vendor

a. Create a task in Task Management named "Warranty Call with Parts" and assign it to the person responsible for warranty processing.

b. The technician adds the warranty parts from the Materials section and attaches documentation (screenshots, photos). The email notifies the person responsible for materials in the warehouse or office that there is a part used that they need to receive from the technician to return it for a credit to the vendor.

Warranty workflows for Pricebook Pro

Apply a vendor credit to your account

a. After the vendor issues a credit for a return or warranty claim, mark the return as Credit Received in ServiceTitan.

b. The vendor credit is added to your accounting batch. Export it to apply the credit against outstanding vendor bills in your accounting system.
