The Numbers at Work Lab · By Zach Houk

Finally understand the numbers at work.

A course on the numbers that get talked about at work. They are the same in every business. You learn what they mean, how to read them, and how to use them to make more money and move up.

What this is

The numbers are the same in every business. Learn them once and they go with you to every job.

6sessions. The whole of business finance.What the company made, what it spent, what’s left, where the budget came from, and why the real year never matches the plan. Plain words, one picture, no glossary.
✓Built on your job’s numbers.Marketing, HR, Ops, Sales, Finance or Product. Every file and every example is one your job actually puts in front of you — and nothing locks, so you can work another role any time.
24/7An AI coach, in my voice.It knows the whole course and every practice file. When you’re stuck you talk to it, and it keeps explaining until it clicks.
How this gets paid for

Before you dive in - it’s important to know that our goal is to get this paid for by your employer. So as you read, decide how valuable and effective this will be for you in your current role and we have all the resources you need to ask your employer to pay for it.

How your company pays →
The problem

You can read the whole report and still not understand the numbers.

Revenue, margin, variance, accrual. The words go past you in the meeting and you don’t want to ask. That is not an intelligence problem. Nobody ever showed you how money moves through a company, so the numbers have nothing to attach to.

How does X impact Y? Seasonal, or one-time? What even is margin? Price, or mix?

The next level expects you to truly understand the numbers.

Manager and beyond means you don’t just read the numbers. You own them, and you defend them.

That sounds like a lot. It isn’t, once somebody draws you the picture. I’ve spent twenty years finding the ways this actually lands, and that is the whole job of this course.

How it works

What a session actually looks like.

01Recorded. You go at your own pace.

Every session is ready when you are. There’s no class to show up for and no cohort to keep up with.

02Me teaching, then you building.

Each session is me teaching in short chapters, then you working it yourself with the coach. Eight hours of each across the six sessions.

03A Boss ends every session.

The Boss is the build at the end: real numbers for your role, worked by you and sent in. The coach reads it and tells you what to fix.

04About two hours a week.

Six sessions, sixteen hours, 60 days of access. Long enough to finish, short enough that you do.

05When you’re stuck.

Talk it through with the coach, any hour. Still stuck? Email me. You can always reach me.

06On your job’s numbers.

Marketing, HR, Ops, Sales, Finance or Product. Pick yours, and switch any time — nothing locks.

The curriculum

Six sessions. Every number your company runs on.

By the end you can read them, explain them out loud, and say what to do about them.

What you’ll be able to do
  • Explain how a company makes money in ninety seconds, out loud, with no notes.
  • Open your company’s P&L, find your team’s line, and say what the page is telling you.
  • Tell a cash problem from a profit problem, and say which one your team has.
  • Build your department’s budget and defend every assumption in it.
  • Name what caused the gap between the plan and the real year, and write the one line that explains it.
  • Make the ask out loud, in their language, and hold your ground on the answer.

All of it on your role’s own numbers.

6 sessions · 16 hours Tap a session for what’s inside.
01The WhiteboardNo slides, no spreadsheet, no glossary — a marker and a wall. The whole of business finance drawn by hand in one sitting, so every document you meet later is a picture you have already drawn.
  • Money in, money out, what’s left. The only equation.
  • Where your own job sits on the board, and which number your job moves.
  • The four questions every business is always asking — and why every report exists to answer one of them.
  • Why nobody ever drew you this.
  • Now you draw the whole board yourself, from memory.
  • You can explain how a company makes money in ninety seconds, out loud, with no notes.
02The ScoreboardThe profit and loss statement, one page at a time: what the company made, what the company spent, what is left, and where your team’s line sits on that page.
  • Revenue, costs, profit. In that order.
  • Cost of goods versus operating expenses — the split that decides who gets blamed.
  • Margin, and the four different things people mean when they say margin.
  • Finding your own team inside a document nobody ever showed you.
  • Reading a real profit and loss statement end to end, out loud.
  • You can open your company’s P&L, find your team’s line, and say what the page is telling you.
03The Timing TrapA profitable month can still leave less money in the bank. Once you can explain why, half the arguments you have sat through at work start making sense.
  • The profitable month with less money in the bank.
  • When a sale counts versus when the cash actually clears.
  • Receivables and payables, one plain sentence each.
  • Accruals — the word you finally have a picture for.
  • Why the thing you ordered in March hits the budget in May.
  • You can tell a cash problem from a profit problem, and say out loud which one your team has.
04Where the Number Comes FromWhat your team is allowed to spend next year, and who decided that number. Then you build a budget yourself, assumption by assumption.
  • October: who actually sets the number, and how.
  • Top-down or bottom-up — and which kind of budget you are really in.
  • Assumptions are the whole budget, so you name your own out loud.
  • Your department’s next year, built line by line.
  • Headcount: the biggest line, and how headcount gets argued.
  • Sandbagging: what padding a budget means, why everyone pads, and what padding badly costs you.
  • You can build your department’s budget and defend every assumption inside that budget.
05The VarianceThe plain question of why the real year never matches the plan. Every variance comes down to price, volume or timing, and you learn to sort any of them into one of the three.
  • Budget, actual, variance — and reading the parentheses.
  • Favorable and unfavorable, and why a favorable number is not always good news.
  • Price, volume, timing. Every variance is one of the three.
  • One-time, or the new normal? Telling a blip from a trend.
  • Writing the explanation: one line first, then the backup.
  • You can look at the variance between the plan and the real year, name what caused it, and write the one line that explains it.
06The AskSomebody in every department has to explain the year and ask for what comes next. This session makes that person you.
  • What an ask looks like from the other side of the table.
  • The number and the reason. Never a spreadsheet.
  • Payback, and rough math that is good enough to be believed.
  • Building the one-page case.
  • The three objections you will get, and the answers.
  • Asking for headcount, asking for budget, asking for yourself.
  • You can make the ask out loud, in their language, and hold your ground on the answer.

About all that AI hype

AI multiplies what you already know. So know something.

AI can produce a report in ten seconds. It cannot tell your boss what the report means, and it cannot tell you when it’s wrong. The people who understand how the numbers work are the ones AI makes more valuable, not less.

So I teach it. Easy, practical ways to use AI for real work you could do tomorrow. And the part that matters more: how to know, fast, whether what it handed you is even right.

Zach Houk
The coach

Like having me on call.

It’s an AI coach. I cloned my own voice and handed it the entire curriculum, every practice file, and 20 years of my finance opinions. You talk, it talks back.

I’ve spent twenty years finding the ways this stuff actually lands for people who never got it in school. The coach has every one of them, at 11pm, as many times as you need. Nobody is judging you. Nobody is bored of the question.

“Profitable month, less cash in the bank. Walk me through where the money went.”

The other side

There’s a version of your life on the other side of these numbers.

01 / The paycheck

The raise you stopped waiting for someone to offer you.

02 / The meeting

The gap you explain in one line, before anyone asks.

03 / The budget

The budget you build and defend, line by line.

04 / The ask

The person who explains the year and asks for what comes next.

The point

None of this is about accounting — it’s about what it buys you.

The difference

Here’s exactly what you’re getting.

The Excel Lab is the tool. Numbers at Work is the game the tool is played in. The Stack is both.

The other half of the Stack

The Excel Lab

The 20% of Excel that actually matters, taught as one connected system — so it finally sticks. This is the “tool” part of making more money.

The launch special · Limited capacity

An actual reference letter for your career.

Everyone else gives you a certificate. I read your actual work.

I taught business at a college — youngest they ever hired — and I’ve spent twenty years in finance since. I’m not telling you that to impress you. I’m telling you because you’re about to pick someone to learn this from, and you should know who’s actually on the other end.

And yes I’m grading your actual work and signing your personal reference letter if you truly learn what I teach you.

  • It has to be earned — that’s the only reason it’s worth having.
  • If the work isn’t there yet, you get exactly what to fix and another go.
  • This doesn’t scale, so I’m taking a limited number. When it’s full, it’s full. Stack only.

Your company pays

You probably won’t pay for this.

It comes out of a training budget, like a conference does. I’ll invoice your company directly, or you expense it with a proper invoice. I’ll even write the request for your manager. How it works →

Paying yourself

Split it up.

Payment plans at checkout. Same price, spread out.

The guarantee

Forty-five minutes. In or out?

Watch the first three chapters of The Whiteboard — about 45 minutes — then I ask you point-blank. Out — full refund, every dollar. In — we finish what we started, and refunds are off the table.

Before you ask.

Do I need to be in finance to take this?

No — it’s built for people whose jobs touch the numbers without being about the numbers. Marketing, ops, sales, HR, product. You pick your department and the course meets you there.

I’ve tried to learn this before and it didn’t stick. Will this be different?

Most courses open with a glossary. This one opens with numbers you already recognise — by the time the vocabulary shows up, you already know the thing it’s pointing at.

Do I need Excel skills to take this?

No. This course is about the numbers, not the tool. If you want both, that’s exactly what the Stack is for.

What’s the difference between this and the Excel Lab?

The Excel Lab is the tool. This is the game the tool is played in — the numbers themselves. The Stack is both.

Is it live, or recorded?

Recorded. Every session is ready when you are, so you go at your own pace. The coach is there any hour, and you can email me any time.

How much time does it take?

Sixteen hours in all across six sessions: eight of me teaching, eight of you working it with the coach. Spread over the 60 days, that’s about two hours a week.

What if my job isn’t one of the six roles?

Pick the closest one. Nothing locks, so you can work another role’s numbers any time. The numbers are the same in every business.

What does the Stack add?

The whole Excel Lab, Cash Money, the “Accounting for Cool People” cheatsheet, and the Final Boss — the one I read myself, with the reference letter if you earn it.

Can my company pay for it?

Usually, yes. It comes out of a training budget, like a conference does. I’ll invoice your company directly, or you expense it with a proper invoice — and I’ll write the request for your manager. Here’s how it works.
