Why tracking serial numbers matters for warranty and maintenance
Warranty claims depend on accurate equipment identifiers. If a unit fails, the manufacturer needs the specific serial number to verify coverage. Without that number, the claim may be rejected or delayed. For construction contractors managing site equipment, this record is part of the submittal file. It proves what was installed and when.
Consider a common scenario. A technician installs a $5,000 furnace and needs to record its serial number for warranty registration, according to ServiceTitan. This example highlights the direct link between the physical unit and its financial and legal record. The $5,000 value represents the asset at risk. The serial number is the key that unlocks the warranty protection for that specific item.
Timing is critical for maintaining this link. You should record serial numbers immediately when you unbox new equipment to avoid forgetting later, according to ServiceTitan. Waiting until the end of the shift or the end of the week creates gaps. In a busy job site, equipment moves quickly. A serial number written on a sticky note or in a phone message is vulnerable to loss. Immediate recording ensures the data is captured while the context is fresh. It prevents the need to search for the unit later just to find its identifier.
How to record serial numbers immediately upon installation
Capture the serial number when you unbox the equipment. Do not wait until the invoice is finalized or the job is closed.
1. Verify the pricebook setting. Before the crew heads to the site, confirm your office has marked the specific equipment or material item as Tracked by Serial Number in the pricebook. According to ServiceTitan, this office-side setup is the prerequisite for field capture.
2. Scan or select the number on the invoice. Once the item is added to the job's invoice, you can scan or manually select the serial number. According to ServiceTitan, this action happens directly when adding the item to the job's invoice. Use a barcode scanner if available, or type the number manually if the label is damaged.
3. Check the quantity match. If you are installing multiple units of the same model, ensure each unit gets its own unique identifier. According to ServiceTitan, installed equipment generated from serialized inventory will generate a piece of installed equipment for each quantity of the invoice item. This means a line item for three units should result in three distinct serial number entries, not one.
4. Verify the link before leaving the site. Before the crew moves to the next location, open the invoice screen and confirm the serial numbers are attached to the correct line items. If a number is missing, correct it immediately while the equipment is still in front of you.
Action step: Print or screenshot the invoice line items with the serial numbers visible and attach them to your daily site log, such as the one in our Construction Daily Log Checklist for Supervisors. This physical or digital proof confirms the data was captured at the time of installation.
Illustrative example: three identical units on one job
A crew installs 3 identical units of one model on a single job. The invoice shows one line item with a quantity of 3. Before leaving, the lead opens the invoice and checks the serial number entries. Three distinct entries are present, one for each unit, so the lead matches each number to its location on the worksheet. If only 1 entry were present, the lead would correct it on site while all the units are still within reach. This example is illustrative only.
Automating asset creation from work orders
You can automatically create customer assets when you add a product to a work order and use the product during the work, according to Microsoft. This process applies to field service assets, which allows you to track equipment that requires inspections, maintenance, and repairs, according to Microsoft. The system handles the record generation when the status of the work order changes to Open-Completed or Closed-Posted, according to Microsoft. At that specific status change, the system automatically creates the customer asset record and associates it with the service account that appears on the work order, according to Microsoft. This automation links the physical equipment to the digital service account without manual data entry for the asset creation step.
To use this feature, ensure the product is added to the work order before the crew begins the installation or repair task. The work order status must reach Open-Completed or Closed-Posted for the automatic creation to trigger, according to Microsoft. If the work order remains in an earlier status, the asset record does not generate automatically. This mechanism supports tracking equipment that requires inspections, maintenance, and repairs by establishing the asset record at the point of completed work, according to Microsoft.
Review your current work order process to identify which installed items are missing unique serial number fields.

Preventing duplicate records and managing inventory levels
Duplicate rows can creep into your data when you or others enter data manually or import data in bulk, according to Microsoft. To manage this risk during file transfers, if the imported file contains assets that already exist in Field Service, the duplicate records are skipped by default, according to Microsoft. This applies to file imports. For records already entered, see our guide on merging duplicate customer records.
Inventory controls help prevent errors when assigning products to work orders. You can restrict the system to prevent using a work order product when inventory in the specified warehouse is 0, according to Microsoft. Alternatively, you can configure the system to display a warning message when there's an attempt to use a work order product and inventory is 0, according to Microsoft. These settings allow you to choose between a hard stop or a soft alert based on your site's operational needs.
Worksheet for logging site equipment identifiers
Use the worksheet below to log the core identifiers for each unit you install. The goal is to capture the minimum data needed to match a physical unit to its warranty documentation and property record. When you install a new unit, add a row immediately so the serial number is tied to the correct date and location.
| Equipment item | Serial number | Date installed | Location on site | Warranty document |
|---|---|---|---|---|
| Example | Copied from the unit label | Day the unit was installed | Room or area of the building | Warranty certificate in the site file |
ServiceTitan notes that you can upload image, PDF, and MP4 files, such as product brochures, warranty certificates, dimensional drawings, and instructional videos, which may help technicians when presenting estimates according to ServiceTitan.
Keep this sheet in your site file or link it to your work order management system. If you use a digital tool, ensure the serial number field is required so no record is saved without it.
Next step you can take today
Open your most recent invoice and check that every installed unit has its own serial number entry. Add any missing numbers to your worksheet while you still have access to the equipment labels.
FAQ: how to track installed equipment serial numbers for warranty records
When should I record the serial number for a new furnace?
