Parts Inventory

Every part. Every truck. Every location. One connected inventory.

Field service businesses lose first-visit fix rate when a technician arrives without the right part — and lose margin when parts are used but never charged. HieCOR Parts Inventory connects every part from the catalog through the truck inventory to the work order to the invoice — so the right part is available before departure, logged at use, billed on the invoice, and replenished before the truck runs empty.

Parts Lifecycle

From parts catalog to truck restock — one connected parts inventory workflow.

Parts management breaks when catalog, truck inventory, usage logging, billing, and replenishment live in separate systems. HieCOR connects every step from parts catalog through reconciliation in one field service parts platform.

1Catalog

Every part in one connected catalog — with availability by location.

Every part, consumable, and supply your technicians use lives in the HieCOR parts catalog with a part number, description, supplier, cost, and real-time stock position by location — warehouse, truck, and branch. When a technician searches for a part on a work order, they see exactly what is available, where, and at what price — before they commit to using it or order it for the customer.

2Check

Know before you dispatch whether the technician has the part on the truck.

Before a technician is dispatched, HieCOR checks the parts required for the job — from the work order, the diagnostic history, or Mark AI's recommendation — against the inventory on that technician's truck and in the nearest warehouse. Alex AI flags shortages before departure so the dispatcher can pull a part from another location, order it, or assign a technician who already has it on their truck.

3Use

Technician logs parts used from the work order — inventory updates instantly.

When a technician uses a part on a job, they log it directly from the work order on their mobile device. The part is removed from the truck inventory in real time, the cost is applied to the work order, and the part appears on the invoice automatically. No manual parts tracking sheet, no end-of-day reconciliation, no parts that were used but never charged.

5Transfer

Move parts between trucks and locations without losing track of what is where.

When a technician on the road needs a part they do not have, the dispatcher can initiate a branch-to-truck or truck-to-truck parts transfer from HieCOR — or identify the nearest technician who has the part and reassign the job. Every transfer is logged against both inventory positions in real time. No parts going missing between the warehouse and the truck.

6Reconcile

See exactly what is on every truck — and what should be on every truck.

HieCOR tracks the expected parts inventory on every truck (based on restocks minus usage) alongside the actual count from periodic reconciliation. Alex AI flags discrepancies — parts that were used but not logged, parts that appear missing, and trucks running below minimum levels for their typical job mix. No mystery parts disappearing between the warehouse and the job site.

Why HieCOR

What changes when parts inventory is connected to dispatch, work orders, and invoices.

The operational gaps most field service businesses live with every day — and what HieCOR does differently.

Situation	Without HieCOR	With HieCOR
Technician arrives at a job without the part	✗Technician calls the warehouse, waits for a callback, schedules a return visit, customer is frustrated — first-visit fix rate drops	✓Alex AI checks parts required at dispatch — shortage flagged before the technician leaves, with time to pull from the warehouse or reassign to a tech who has the part
Tracking what parts are on each truck	✗End-of-week manual count by each technician. Numbers are never quite right. Discrepancies discovered after parts are already missing.	✓Real-time truck inventory updated at every use and restock — Alex AI compares expected vs actual and flags discrepancies before Monday dispatch
A part is used on a job but never charged	✗Technician used the part, forgot to log it, it never appeared on the invoice — margin leak that compounds across dozens of jobs per week	✓Part logged from the work order on the technician's mobile device — automatically deducted from truck inventory, costed to the work order, and added to the invoice
Restocking truck inventory	✗End-of-week or when a technician calls to say they've run out — reactive, inconsistent, some technicians run out mid-week	✓Alex AI surfaces replenishment recommendations based on usage velocity and the upcoming week's job schedule — restocking happens before the truck runs empty
Knowing which parts need to be ordered	✗Manual review of inventory counts — whoever remembers to check before ordering. Some parts run out, some are over-stocked.	✓Alex AI monitors stock levels in real time and generates replenishment recommendations with suggested quantities based on historical usage — one-click PO creation
A technician needs a part on a job they don't have	✗Technician calls the office, dispatcher tries to find a supplier, customer waits — or the job is rescheduled	✓Dispatcher initiates a truck-to-truck transfer or identifies the nearest tech with the part — both inventory positions updated in real time

Use Cases

Built for every type of field service parts management operation.

HieCOR Parts Inventory works for appliance repair, HVAC, plumbing, electrical, garage door, equipment service, and any field service operation managing parts across multiple technicians and locations.

Multi-truck operation

Managing parts across 8 technician trucks

You have 8 technicians, each with their own truck and parts inventory. Every Monday morning, Alex AI surfaces which trucks are below minimum for the week's scheduled job types. Dispatcher reviews the replenishment recommendations, pulls parts from the warehouse, and has every truck restocked before 8am. First-visit fix rate up 22% in 90 days.

First-visit fix rate improved 22% in 90 days

HVAC service

Parts availability at dispatch for every service call

Your HVAC technicians carry 40–60 SKUs on their trucks. Before each technician is dispatched, HieCOR checks the job requirements against their truck inventory. When a technician is assigned to an AC unit repair but does not have the capacitor in stock, the dispatcher is alerted before the tech leaves — not after they arrive and have to come back.

Shortage alert before the technician leaves the shop
Resolution options — warehouse pull or reassignment — surfaced immediately

Appliance repair

Parts logging from the work order in the field

Your appliance technician replaces a lid switch on a washer. They log the part from the work order on their mobile device. The part is removed from their truck inventory, the cost is applied to the work order, and it appears on the customer's invoice automatically. The technician drives away with an accurate parts count and an accurate invoice — without doing anything manually.

Truck inventory, work order cost, and invoice updated automatically
No manual parts tracking sheet, no end-of-day data entry

FAQ

Questions buyers usually ask first.

Everything buyers ask before deciding whether HieCOR is the right platform.

AwarenessCan HieCOR track parts inventory per technician truck?

Yes. HieCOR maintains a real-time inventory position per truck — updated every time a part is used on a work order or restocked from the warehouse. The dispatcher can see what is on every truck from the dispatch board before assigning a job.

AwarenessCan parts be logged directly from a work order in the field?

Yes. Technicians log parts used directly from the work order on their mobile device. The part is removed from their truck inventory in real time, the cost is applied to the work order, and the part appears on the customer invoice automatically — no manual parts tracking sheet required.

AwarenessDoes HieCOR check parts availability before dispatching a technician?

Yes. Alex AI checks the parts required for each job against the assigned technician's truck inventory and the nearest warehouse before dispatch. If a part is missing, the dispatcher is alerted with the available resolution options — warehouse pull, truck-to-truck transfer, or job reassignment.

EvaluationHow does Alex AI recommend parts replenishment?

Alex AI monitors every truck and warehouse inventory level in real time and compares current stock against usage velocity and the upcoming week's scheduled job types. It surfaces replenishment recommendations — which parts, which trucks, and in what quantities — before stock runs out, not after a technician calls to say they have run out.

EvaluationCan parts be transferred between trucks or from the warehouse to a truck?

Yes. The dispatcher can initiate a branch-to-truck or truck-to-truck parts transfer from HieCOR. Both inventory positions are updated in real time at the moment of transfer. Every transfer is logged for audit and reconciliation purposes.

EvaluationHow does HieCOR reconcile expected vs actual truck inventory?

HieCOR tracks the expected inventory on every truck — based on restocks minus logged usage — and compares it against periodic physical counts. Alex AI flags discrepancies, missing parts, and trucks running below minimum levels before Monday morning dispatch.

DecisionHow is HieCOR Parts Inventory priced?

HieCOR Parts Inventory is included as part of the broader HieCOR service platform. Pricing is based on the modules deployed, number of technicians, and parts SKU volume. Pricing is discussed during the demo.

DecisionWhat does implementation look like for parts inventory?

HieCOR's US-based implementation team handles parts catalog setup, truck and warehouse location configuration, minimum stock rule setup, replenishment workflow configuration, and integration with your purchase order and work order workflows. Most businesses are live within 45 days.
