We know your pain.
We lived it.

InventoryOS was born from real-world frustration managing hundreds of devices, and billing for them, without a single reliable tool. We're building the platform we always wished existed.

The Origin Story

Every great product starts with a problem that won't go away.

The MSP Trenches

It started inside a managed service provider, deep in the day-to-day of keeping hundreds of client devices running. As a Network Security Engineer, the job meant constantly jumping between tools, spreadsheets, and vendor dashboards just to answer simple questions: How many devices does this client actually have? What software is installed? Is our billing even accurate?

The Compliance Gap

Moving into a Cybersecurity & Compliance Manager role made the problem even more visible. Reconciling software licenses, proving compliance during audits, and tracking what was actually running on endpoints. None of the existing tools did it well. Most were designed for large enterprises with massive budgets, and the rest were painfully inaccurate.

The Breaking Point

After yet another billing reconciliation that took an entire week of manual cross-referencing between three different platforms, the realization hit: this tool doesn't exist because nobody who actually does this work has built it yet. The vendors building inventory tools had never sat in the chair of someone who needed accurate device counts to settle a vendor invoice.

InventoryOS Is Born

InventoryOS was built from the ground up to solve that exact problem: a single platform that gives you an accurate, real-time inventory of every device and every piece of software, organized by organization, with compliance rules that actually work. No guesswork. No spreadsheets. No overcharging.

Closing the Billing Loop

Accurate counts were only half the battle. MSPs still lost money between the distributor bill, the PSA, and the client invoice. So we built the MSP Portal: service plans for what you sell, price policies for what each client pays, and billing reconciliation that compares devices and license seats against your invoices, period by period, before invoice day.

Two Founders, One Mission

To take InventoryOS further, John teamed up with Derrick Baker, a business executive with more than 25 years of leadership experience. Together they pair the view from the IT trenches with the discipline of running large, complex organizations, so the product stays practical and the company is built to last.

I spent years managing device fleets and software compliance across dozens of client environments. Every existing solution either gave us incomplete data, cost a fortune, or required an entire team just to maintain. I built InventoryOS because IT teams deserve a tool that’s as straightforward as the job is demanding. Accurate inventory, clear compliance, honest billing.

Practitioner meets operator

InventoryOS is built by people who have done the work. John brings years of hands-on experience inside MSP and compliance teams, so every feature starts with the question an IT admin actually asks. Derrick brings decades of leading large organizations, managing major budgets, and building lasting partnerships.

That mix shapes how we run the company: ship practical tools quickly, price them honestly, and treat every customer relationship like a long-term partnership. You get a product that understands your day and a team that understands your business.

Our Mission

Give every IT team, whether it’s one person or one hundred, a single source of truth for their devices, software, licenses, and billing.

Accuracy First

Inventory data is only useful if it's correct. Every feature we build starts with the question: does this make the data more accurate? We don't ship features that sacrifice data integrity for convenience.

Built for the Practitioner

We design for the person who actually manages the devices, not the person who signs the purchase order. If a feature doesn't save time for the IT admin doing the work, it doesn't ship.

Honest Pricing

Simple per-device pricing that you can calculate in your head. No hidden fees, no per-user charges stacked on top, no "contact us" walls hiding the real cost. You should know exactly what you'll pay before you sign up.

Security by Default

Built by someone with a cybersecurity background, security isn't an afterthought. API key rotation, tamper protection, MFA, and audit logging are all core to the platform, not paid add-ons.

Ship Fast, Listen Faster

As a small, founder-led team, there's no bureaucracy between user feedback and a shipped fix. Feature requests from real users drive the roadmap, not a committee, not investor demands.

Cross-Platform, No Exceptions

Windows, macOS, and Linux are all first-class citizens. Most IT environments aren't one-platform shops, and your inventory tool shouldn't force you to pick favorites.

Why We’re Different

Most inventory tools were built by enterprise software companies selling to procurement departments. They optimize for feature checklists and sales demos, not for the IT professional who needs to answer "how many devices is this client running?" at 4 PM on a Friday.

InventoryOS is different because it was built by people who needed it. Every design decision, every API endpoint, every compliance rule workflow was shaped by years of hands-on experience in MSP and enterprise IT environments.

The result is a platform that's opinionated about the things that matter (data accuracy, software visibility, billing reconciliation) and stays out of your way for everything else.

Other Tools

Inaccurate device counts. Software inventory that misses half your apps. Billing checked by hand across the PSA, the distributor portal, and a spreadsheet. Pricing that requires a sales call.

InventoryOS

Accurate device and software inventory from day one. Billing reconciliation that flags unbilled devices and unused licenses before invoice day. Transparent pricing on the website. Built by the people who answer your support emails.
