Serialized equipment tracking within inventory

Fatima, this is actually one of the more common requirements I encounter in implementations for regulated industries, so let me share what I typically recommend based on the use cases I've worked through.

In my experience, what you are describing—true serialized inventory with unit-level traceability—is not natively supported in the current FieldPulse inventory module. The system is designed around quantity-based SKUs, which works well for consumables and standard parts but creates gaps for capital equipment where individual unit history matters for compliance.

What I typically recommend is a hybrid approach that has worked for several of my clients in similar situations:

Option 1: SKU + Custom Field Workaround

You can create individual SKUs for serialized items (e.g., "PUMP-MODELX-SN0015847") rather than using a generic "PUMP-MODELX" SKU. This allows you to track each unit separately, though it does proliferate your SKU list considerably. You would then use work order notes or custom fields to capture installation location, customer, and technician. The downside is that this requires significant manual overhead and does not provide the automated chain of custody you described.

Option 2: Integration with Dedicated Asset Management

From a governance perspective, this is usually the stronger path. FieldPulse can integrate with systems like Asset Panda, UpKeep, or even a custom database via API. The pattern I have seen work well is:

1. Inventory in FieldPulse remains at the SKU level for dispatch and billing purposes
2. Upon assignment to a technician, the integration creates a record in the asset management system with the specific serial number
3. Technician scans or enters the serial number at installation, which updates both systems
4. Warranty and compliance reporting runs from the asset system, which has the authoritative serialized data

What I typically recommend is starting with Option 2 if your audit requirements are strict, as it provides the immutable record chain that most regulators expect.

It is worth noting that I have heard rumblings about enhanced inventory capabilities on the roadmap, though I do not have confirmed timing I can share.

Would you like me to connect you with a client reference who has implemented the integration approach? I can also share the API documentation for the inventory endpoints if your team wants to evaluate the technical lift.

Hi Fatima, happy to help clarify this!

Priya here from the Support team. Daniel covered the landscape well, so let me add a bit about what is officially supported today.

Native serialization: Not currently available. The inventory module tracks quantities only, as you noted.

Official workaround: If you need serialized tracking for compliance audits, we do have a documented pattern using Custom Fields on work orders combined with Checklist Templates. It is not as seamless as true serialization, but it creates the audit trail you need:

1. Create a custom field on work orders called "Installed Equipment Serial Numbers" (multi-line text)
2. Build a required checklist item: "Record serial number of installed unit and photograph equipment label"
3. Enable Photo Required on that checklist item
4. Filter and report on the custom field via Work Order Reports

This gives you technician attestation + photographic evidence + searchable records. For full chain of custody, pair this with the Parts Used tracking in inventory, which logs which technician pulled stock and when.

See this article for full steps: Tracking Parts Used on a Job

For the integration path Daniel mentioned, our API supports creating custom fields programmatically if you want to sync with an external asset system. The relevant endpoint is /work_orders/{id}/custom_fields.

Does this help clarify your options? I am happy to walk through the checklist setup in more detail if useful.

Thank you, Daniel and Priya, for the comprehensive responses.

I have reviewed the documentation and have a follow-up question regarding data integrity. From a governance perspective, the custom field approach introduces potential for manual entry errors—technicians mistyping serial numbers, for example. It is worth noting that our audit requirements specify that equipment records must be "accurate and tamper-evident."

Does the checklist photo requirement provide sufficient evidentiary weight, or is there any validation layer (barcode scanning, mandatory format enforcement) that can be applied to the custom field itself?

Additionally, with respect to the API integration path: is there a webhook event that fires upon work order completion that could trigger the external asset system update automatically? We would prefer to avoid polling patterns.

Thank you again for your assistance.

yeah this one tripped me up too when I first looked at it—hey Fatima, Eli from Engineering here

so on the validation question: there's no native regex or format enforcement on custom fields, which is honestly a gap I've flagged internally. what you *can* do is use a webhook to validate on your end before committing to the asset system

speaking of which, yes—there's a work_order.status_changed event that fires on completion. payload structure is:

{  "event": "work_order.status_changed",  "data": {    "work_order_id": "wo_abc123",    "status": "completed",    "completed_at": "2026-02-09T11:00:00Z",    "custom_fields": {      "installed_equipment_serial_numbers": "SN-2026-0015847"    }  }}

heads up though: the custom_fields object only includes values that have been set, so if your tech forgets to fill it, you'll get an empty object. worth noting that we don't currently validate required custom fields at the API/webhook layer—only in the UI

pro tip from implementations I've seen: some teams use a middleware validation layer that checks the serial number format against their asset DB before accepting the webhook, rejects back to the tech if malformed. bit of a dance but it works

also on barcode scanning—there's Barcode Scanning for Inventory Management which works for *parts*, not custom fields.yeah I know, it's frustrating. the scanner input can technically write to any text field though, so you could have techs scan into the custom field if you're on Android. iOS locks the camera API a bit tighter

anyway, happy to go deeper on the webhook side if your dev team wants to sync up

in my experience the custom field thing is a headache waiting to happen. techs will find a way to fat-finger serial numbers no matter how many photos you make them take

we stopped trying to track individual units in FieldPulse and just use it for dispatch/billing now. asset tracking lives in a separate system the warehouse guys run. not pretty but it works

if your auditors are strict i'd push hard on the integration route, not the workaround

We've been running serialized tracking for 18 months. Here's what actually works:

• Dedicated "equipment check-out" work order type with required serial number field
• Warehouse staff only—technicians never enter serials, they just scan/confirm
• Zapier pushes to Asset Panda on completion
• Discrepancy reports auto-generated weekly

Key point: split the workflow so field techs don't touch serial entry. Eliminates 90% of errors.
