Show Me the Money: CS Edition

Hi there,

It took me a while to fully understand this.

Customer Success is not about adoption.
It’s not even about keeping your customers happy.

It’s about ROI.

If your customer cannot clearly see the return they are getting from their investment, everything else becomes noise.

Let’s break this down in a practical way.

What is ROI?

ROI stands for Return on Investment.

In simple terms, it answers one question:

Was this investment worth it?

In business, ROI measures the return of an investment relative to its cost. It is usually expressed as a percentage.

The formula is straightforward:

ROI = (Net Profit / Cost of Investment) x 100

Where:

Net Profit = Total Gain from the investment – Total Cost of the investment

That’s it.

Executives use this logic every single day. Whether they are buying software, hiring headcount, opening a new office, or launching a new initiative, they are asking:

• What will we gain?

• What will it cost?

• Does the math make sense?

If the answer is yes, they move forward.

If the answer is unclear, they hesitate.

If the answer is no, they cut it.

A simple example (from my personal life)

I used to spend 2 hours per week manually tracking expenses in spreadsheets.

Logging into my multiple bank accounts.
Classifying every type of expense into a spreadsheet.
Creating formulas to track income and spending.

It worked.

But it was time-consuming.

2 hours per week x 52 weeks = 104 hours per year

If my time is worth $75 per hour, that is:

104 hours x $75 = $7,800 per year.

That’s what my “free” spreadsheet system was actually costing me.

Then I switched to a budgeting tool (YNAB) that costs $191 per year. 

It connects to my bank accounts automatically.
Transactions are categorized for me.
The reports are built in.

What used to take two hours now takes a few minutes.

Now let’s look at the math.

Net profit:

$7,800 – $191 = $7,609.

ROI:

$7,609 / $191 x 100 = 3,983%

When you look at it that way, the decision becomes obvious.

I’m not paying $191 for a tool.

I’m investing $191 to recover $7,609 worth of time and mental energy.

That is an obvious investment.

Businesses think the exact same way.

Just with a lot more zeros!

What ROI means in Customer Success

Customers do not buy software for features.

They buy it because they believe the investment will:

• Increase revenue

• Reduce costs

• Improve productivity

• Reduce risk

In other words:

It makes financial sense.

Your job as a CSM is to make that financial sense visible.

Not assumed.
Not implied.
Visible.

For example, in the workplace technology industry that I work in, ROI might look like:

• Reducing real estate footprint

• Increasing space utilization

• Lowering cost per seat

• Eliminating manual reporting (productivity, time saved)

In the MarTech space, it might look like:

• Increasing pipeline

• Improving conversion rates

• Reducing customer acquisition cost

Different industries. Same principle.

ROI is the bridge between product usage and executive value.

How to calculate ROI in your accounts

You do not need a finance degree to do this.

You need clarity.

Start with three simple questions:

1. What was the customer doing before?

2. What changed after implementing your product?

3. What is the financial impact of that change?

Let’s use a workplace example.

Before:

• 15,000 square feet

• 20% utilization

• $345 per square foot

• Total annual cost: $5.1M

After optimization:

• 7,000 square feet

• 60% utilization

• Same cost per square foot

• Total annual cost: $2.4M

Net savings:
$5.1M – $2.4M = $2.7M

Now imagine your software costs $300,000 per year.

ROI:
$2.7M / $300,000 x 100 = 900%

That changes the conversation.

Now you are no longer discussing “feature adoption.”

You are discussing $2.7M in savings.

Why this matters to you

Last week, I asked you where you are in your CS journey.

43% of you said you are already managing enterprise or strategic accounts.

At that level, ROI is not just helpful.

It is expected.

Enterprise customers operate under constant scrutiny.
Budgets are reviewed.
Procurement gets involved.
Every line item is questioned.

And when renewal season comes around, the conversation becomes very simple:

“What did we actually get from this investment?”

This is where many CSMs struggle.

They show:

• Adoption charts

• Feature usage

• Training sessions delivered

• Support tickets resolved

But none of those answer the question executives actually care about.

What was the business impact?

When you can quantify ROI:

You defend renewals.
You create expansion opportunities.
You earn executive credibility.

And most importantly, you shift the conversation away from price and toward value.

Executives do not renew contracts because users like the interface or because they are logging in.

They renew because the investment makes financial sense.

Period.

ROI is not just about savings

Sometimes ROI is about:

• Avoided risk

• Improved compliance

• Faster decision-making

• Increased employee satisfaction tied to retention

Not everything fits neatly into a spreadsheet. But even qualitative impact should connect back to business results.

A useful question to ask yourself is this:

“If this product disappeared tomorrow, what financial or operational gap would it create?”

If the answer is unclear, there is probably more work to do.

Final thought

ROI is not just a financial metric.

It is a credibility metric.

When you can translate product outcomes into financial outcomes, you change how you are perceived.

You stop being the person who manages accounts.

You become the person who drives business impact.

And in a world where roles are evolving, and AI can automate tactical work, strategy and financial fluency are not optional skills.

They are your edge.

If you want to go deeper into how to define outcomes, tie them to measurable metrics, and build Success Plans that make ROI obvious, that is exactly why I wrote the Success Plan Playbook (coming soon!)
