Unit Cost Architecture

Your tech costs are on the P&L.
What they cost per unit isn't.

Margineer deconstructs your consolidated COGS lines bottoms-up—isolating cloud infrastructure, LLM token consumption, third-party APIs, and technical delivery payroll. We transform raw operations data into clear, defensible gross margins so you can optimize pricing ahead of rising costs.

The Problem

One line on the P&L. Six things blended into it.

Your COGS is already consolidated — that's what accounting is for. It's just too blended to answer the question that actually matters: does the price still cover what it costs to deliver?

01

Cloud & Hosting

AWS, GCP, Azure, and owned infrastructure that scales with usage — one part of a bigger, blended COGS number.

02

AI & LLM Consumption

Claude, OpenAI, and other model costs billed by the token — often the fastest-growing line nobody's isolated yet.

03

Embedded Software & APIs

Auth0, SendGrid, Twilio, and other vendor APIs baked into what it actually costs to deliver the product.

04

Merchant Processing Fees

Stripe, Adyen, and gateway fees that scale as a % of gross revenue — a different lever than usage-based software.

05

Production & Delivery Headcount

The fully loaded cost of DevOps, SREs, and technical support keeping the product live for customers.

06

Capitalized Product Amortization

Non-cash amortization of capitalized development costs — easy to omit until an audit finds it.

How It Works

From one blended COGS line to a price per unit.

Enter revenue, units, and your six COGS lines.
Cloud, AI usage, embedded software, merchant fees, delivery headcount, and capitalized amortization — broken out, not blended.

This is the number a blended COGS line never shows you directly — and the one your pricing should be built around.

The Playbook

A working reference for
pricing ahead of rising costs

Not a framework to memorize — a set of tools to reach for when you're building a budget, setting a price, or trying to figure out why margin slipped.

01 — Framework

The COGS breakdown

This is the detail sitting inside the single COGS line on your income statement. Naming each part separately is what makes gross margin actionable instead of just reportable.

Cloud & Hosting

What scales with usage

AWS, GCP, Azure, and owned or colocated infrastructure billed by consumption. The most usage-sensitive line — it moves with every customer you add, whether or not your price does.

AI & LLM Consumption

What scales with every request

Claude, OpenAI, and other model or inference costs — priced by token or request, moving with usage in a way flat subscriptions rarely account for. Increasingly one of the fastest-growing lines in the stack, and one of the least isolated.

Embedded Software & APIs

What's built into the product

Auth0, SendGrid, Twilio, and other vendor APIs embedded in product delivery — distinct from internal tools, which are overhead, not COGS.

Merchant Processing Fees

What scales with revenue, not usage

Stripe, Adyen, PayPal, and other gateway fees — typically a fixed percentage of gross revenue plus a per-transaction charge. Blended into "software," it hides a lever that moves in lockstep with growth rather than efficiency.

Production & Delivery Headcount

What people cost to keep it live

The fully loaded cost of DevOps, SREs, and Tier-1/2 technical support directly required to keep the product running — not account managers or R&D headcount building what's next.

Capitalized Product Amortization

What GAAP requires you to see

Under standards like ASC 350-40, development costs capitalized during the application development stage get amortized into COGS once the product goes live — a non-cash line non-finance founders routinely miss.

The Approach

Built by people who've
priced a product against
rising cost, not just studied it

Margineer is a free tool from Marginwell Advisory — a fractional VP of Finance, Technology & FinOps practice. The calculator is the first look; the teardown is where the real work happens.

Why this exists

Most cost tools stop at spend

Cloud cost tools optimize cloud. Procurement tools optimize contracts. AI usage — Claude, OpenAI, and the rest — usually gets buried inside whichever of those it was easiest to bill to. Almost nothing connects the resulting COGS back to gross margin and price.

What the calculator is

A first read, not a full audit

Six COGS lines and a unit count won't catch everything — a mispriced enterprise contract, an unamortized software asset, or usage-based cost hiding inside a flat category. What it will do is tell you, honestly, whether your price still covers your cost. That's the point.

What the benchmarks are

Starting points, stated plainly

The margin ranges behind every stamp are general practitioner guidance, not a proprietary dataset claiming false precision. They're visible in the Playbook because a benchmark you can't see isn't one you can trust — or challenge.

What happens after

A teardown, line by line

A "Watch" or "At Risk" margin means cost is outrunning price somewhere specific — not where, or by how much. That's the work a full engagement does: COGS line by line, against your actual contracts and pricing.

Marginwell Advisory

Fractional VP of Finance, Technology & FinOps

Rising COGS changes how you have to price. That's a specific problem, and a generalist fractional CFO usually isn't the right fit for it. This is a small, capped practice that works only on margin and cost questions, for technology companies from growth-stage SaaS to established enterprise.

Case Study — Technology Cost Governance

A nine-figure technology
expense base nobody
could attribute

Governance built across public, private, and PE-backed technology organizations. An eight-figure engineering savings mandate was set for the year. It was met in full — and roughly seven of every ten dollars came out of software, cloud, and hosting before compensation was ever sized. Client details, geographies, and ownership structures are withheld; figures and mechanics are representative.
