Built What SimPROCouldn't Deliver

A custom inventory management system for a security contracting firm — because their field service platform left a paper trail on zero jobs. FieldStock changed that completely.

The Problem

SimPRO is strong at billing.
Inventory accountability? Zero.

This security contracting firm was using SimPRO as their core field service platform and paying for it every month. What they weren't getting: any reliable answer to "what did we actually use on that job."

Before FieldStock — SimPRO's Inventory Failures

  • Allocates items to a job but has zero mechanism to track what was actually consumed vs. what came back
  • No way for a field technician to say "I used 6 cameras, not 10 — here's what I'm returning"
  • Inventory discrepancies accumulate silently — missing parts, phantom stock, unresolvable job costing
  • Techs showing up to warehouse with no structured pull process — just memory and paper
  • No warehouse-level visibility into what's been picked, staged, or in-field per job
  • Multi-visit jobs with no running tally — each visit looked like a new, unrelated transaction
  • No damaged/returned goods workflow — items just disappeared from the record
  • No mechanism to handle returned or damaged goods — there is no workflow for a tech to say "this camera was DOA, here is what came back"
  • SimPRO staff IDs and actual technician profiles are disconnected — job assignments sync with null assigned_tech_id, meaning automated routing is impossible
  • Pick ticket and pull workflow does not exist — your warehouse manager is working from memory, whiteboards, or a text message from the dispatcher

"SimPRO is a billing and scheduling tool. It was never built to be an inventory accountability system. That gap costs field service companies real money every month."

What FieldStock Does Instead

Eight workflows SimPRO never had.

Master Warehouse Inventory
Full SKU-level warehouse tracker with real-time on-hand quantities, reorder points, and bin/shelf/row location for every item. Separate from SimPRO — the true source of truth.
Job-Synced Pick Tickets
Jobs sync from SimPRO via API. Managers create pick tickets tied to a job number and assigned technician — specific items, specific quantities, staged and ready before the tech arrives.
Tech Check-In / Check-Out Workflow
Technicians sign into FieldStock on their phone before arriving at the warehouse. They confirm receipt of pulled items, then log exactly what was installed, returned, or damaged at job completion. This record is permanent.
Consumption vs. Allocation Reconciliation
The system automatically calculates the delta — what was allocated vs. what was consumed. Discrepancies are flagged for manager review. No more phantom inventory.
Multi-Visit Job Tracking
Jobs spanning multiple days maintain a running total across all pick tickets — total pulled, installed, still in field, and damaged. First time this company could see a job's full material story in one place.
Warehouse Pick List View
Print-optimized and phone-optimized pick list for warehouse staff — item name, quantity, Row/Shelf/Bin location, checkbox per line. Built for the person walking the shelves.
Role-Based Access
Admins see everything. Managers handle job assignment and warehouse operations. Technicians see only their assigned jobs and their workflow — nothing else. SSO via Azure Entra ID.
PDF User Guide
Full documented user guide delivered with the system — every workflow, every role, every screen. Not a verbal handoff.

Real Scenario

A real morning without FieldStock

It's 7:15am. Two techs are heading to the warehouse to pick up parts for separate jobs. Neither has been formally told what to pull. One looks at a group text from yesterday. The other calls the dispatcher. The warehouse manager pulls items from memory. One job gets the right cameras — the other gets shortchanged and the tech doesn't find out until he's on site 40 minutes away. That job gets rescheduled. The customer is frustrated. Nobody knows how many cameras are actually left in the warehouse because SimPRO says one number and the shelf says another.

FieldStock eliminates every failure point in that scenario.

Replaced

Off-the-shelf inventory add-ons that didn't integrate with field workflow — and a spreadsheet system held together by hope.

The Outcome

"For the first time, this security contracting company knows exactly what left the warehouse, who took it, what job it went to, and whether it came back."

Not in SimPRO. Not on a spreadsheet. In a system built specifically for how their team actually works.

Also built for van-based field service

Running HVAC, plumbing, electrical, or low-voltage crews? The same core platform adapts to track what's in every vehicle.

Barcode & QR Scanning

Scan parts in and out of vans, job sites, and warehouses with any mobile device. No dedicated scanner hardware required.

Van / Vehicle Stock Tracking

Each technician van maintains its own live inventory. Dispatchers see exactly what every vehicle is carrying before scheduling a job.

Syncs with SimPRO

Two-way sync with SimPRO means parts usage on a job is reflected immediately. No double-entry, no spreadsheets, no reconciliation headaches.

Usage & Cost Reporting

Know exactly which parts are consumed most, which techs use more material than quoted, and where shrinkage is happening.

Asset-Level Accountability

Serialized assets like tools and equipment are assigned to a specific technician. Accountability is built in, not bolted on.

How we get you up and running

Live dashboards give management real-time visibility. We help you tune thresholds and reports over the first 30 days.

Built for field service companies running SimPRO

FieldStock is designed for companies that run SimPRO as their core field service platform and are frustrated that warehouse or van-level inventory still lives in spreadsheets, whiteboards, or nowhere at all.

Ideal for security, HVAC, plumbing, electrical, and low-voltage companies with 5–100 technicians. Whether you have 3 vans or 30, FieldStock scales without complexity.

Security & Low Voltage Contractors
HVAC & Mechanical
Plumbing & Pipefitting

Common Questions

Do I need to be a SimPRO customer to use FieldStock?
FieldStock was built specifically to extend SimPRO and requires an active SimPRO subscription for the job-sync features. That said, the warehouse and pick ticket system can stand alone — contact us to discuss your setup.
What SimPRO plan is required?
FieldStock works with SimPRO's API, which is available on Business and Enterprise plans. Contact us and we'll confirm compatibility with your specific tier.
Can this be customized for our specific workflow?
Yes — that's the entire point. FieldStock was built as a custom system for one company's specific workflow. We build it for yours too. Every implementation is tailored.
Does it work with SimPRO's existing catalog?
Yes. We import your existing parts catalog from SimPRO during setup. There is no need to re-enter products.
Do you provide ongoing support?
Yes. As a Clear IT Path client, you have access to our help desk for FieldStock as part of your service agreement. We push updates and handle SimPRO API changes on our end.
