How to invest your company cash - 101

Managing corporate cash is one of the most overlooked responsibilities in a business. Most companies focus on revenue, payroll, and invoices - and forget that idle cash is a financial waste.

Money that just sits in a bank account loses value every day due to inflation and foregoes the opportunity to strengthen the company’s financial position.

Taking good care of excess cash on hand can do amazing things for your company's financial health. Treasury management doesn’t need to be complicated.  At a basic level, it simply means keeping your company liquid, safe, and earning a modest, reliable return.

This guide breaks down treasury management in a way that works for startups, small companies, business owners, and CFOs. It covers the basic principles, the simplest tools, and what modern options fit naturally into a responsible cash strategy.

Understanding corporate treasury: The basics

Corporate treasury is the part of the business that manages:

  • Cash entering the company
  • Cash leaving the company
  • How much liquidity the business needs to operate
  • Where to invest the surplus

Think of treasury as the company’s internal “financial engine room”. If it runs well, the entire business feels safer and more stable.

For smaller companies, treasury often sits with the founder, CFO, or head of finance - and usually without any formal structure. But even a simple, clear setup can give a company a major advantage: steadier liquidity, better planning, and higher returns on idle cash.

Treasury focuses on two essentials:

1. Liquidity

The company must always have enough cash available to pay suppliers, run payroll, and handle unexpected expenses

2. Risk control

The company should not take unnecessary financial risks for the sake of yield. Treasury prioritises staying safe first - returns second.

The core principles of treasury investment

There are three non-negotiable principles you should follow when managing corporate cash:

1. Know your risk tolerance

For small companies, risk tolerance should be:

“Don’t lose money.”

Treasury is about capital preservation. That means:

  • Avoiding volatile assets
  • Avoiding anything with long lock-ups
  • Avoiding complex products you don’t understand

2. Diversify your allocation

Don’t put everything in one bucket. Even for small companies, you want:

  • Some cash reserves immediately available
  • Some placed in safe short-term instruments
  • A small portion in slightly higher-yield products with controlled risk

3. Respect liquidity needs

Every company should know its:

  • Operational cash (money you need immediately)
  • Reserve cash (buffer for 3-12 months)
  • Investable surplus (anything above the buffer)

Good treasury management is simply about allocating these three buckets wisely.

Setting up a treasury investment policy

Even a two-page document is enough to create structure. Your treasury policy should state:

  • Your goals (preserve capital, stay liquid, earn a modest return)
  • What instruments you can use (MMFs, T-Bills, deposits, digital credit, etc.)
  • Limits (e.g., no more than 20-30% in any single product)
  • Liquidity rules (e.g., keep at least 3 months of expenses in instant cash)

This prevents emotional or impulsive decisions.

It also makes internal approvals easier and keeps everyone aligned.

Treasury cash management: Optimising liquidity

Cash management is about making sure the company never runs short.

This involves:

  • Forecasting upcoming payments
  • Tracking receivables
  • Building a minimum liquidity buffer
  • Identifying the amount of cash surplus to invest

For small companies, the biggest issues are usually:

  • Unpredictable invoices
  • Late payments
  • Seasonal swings
  • Raising cash only when it’s too late

A small improvement in cash forecasting makes treasury investment possible. Once you clearly know what part of your cash must stay liquid, everything else can be invested safely. As a small business, consider setting up an emergency fund to cover unexpected invoices or shortfalls from late payments.

Investment strategies for corporate treasury

Treasury investments fall into three simple categories:

1. Immediate liquidity (0-7 days)

This is your operational cash used to cover business operations and should remain in:

  • Current accounts
  • Instant-access savings accounts
  • Overnight deposits

Low return, but absolute safety and easy access.

2. Short-term investments (1-6 months)

This is typically where most treasury sits. Options include:

  • Money market funds (MMFs)
  • T-Bills
  • Short-term government paper
  • Short-duration deposits
  • Digital credit products offering short-term, secured lending

3. Longer-term investments (6 months - 3+ years)

Less relevant for treasury unless you have a large cash cushion.

These include:

  • Bonds
  • Equities
  • Structured products
  • Real estate

Long-term assets fluctuate in value and shouldn’t be used for operational cash.

Treasury risk management: Balancing safety and yield

Risk management is simply asking:

  • Is the return worth the risk?
  • What could go wrong?
  • How fast can I get my money back?

CFOs mainly face:

  • Interest rate risk: Rates move and your returns change.
  • Credit risk: The borrower fails to repay.
  • Liquidity risk: You can’t withdraw when needed.
  • Operational risk: Poor reporting, complex products, or misaligned incentives.

Leveraging technology and automation in treasury

Modern treasury tools give finance teams:

  • Real-time reporting
  • Automated cash forecasts
  • Scenario modelling
  • Instant updates on positions

Today, treasury platforms offer more transparency than ever before: Positions are tracked continuously, and reporting doesn’t usually rely on quarterly statements. That makes it easier for CFOs - especially in smaller teams - to maintain oversight without hiring a dedicated treasury analyst.

Building a resilient treasury team and governance structure

To take good care of your treasury, you don’t need a large team - you need clarity.

For a mid-size company, you need at minimum:

  • CFO: defines risk limits and approves products
  • Accountant/Controller: tracks cash and reconciliations

Their treasury governance should cover:

  • Approved instruments
  • Withdrawal rules
  • Diversification limits
  • Liquidity thresholds
  • Review schedule

Measuring success: KPIs and continuous improvement

Evaluating treasury operations involves defining key performance indicators (KPIs). These metrics help assess whether financial strategies align with business goals. Clear KPIs provide insight into liquidity, risk management, and investment performance.

Common Treasury KPIs:

  • Liquidity ratios
  • Weighted average yield
  • Weighted average liquidity
  • Risk-adjusted returns
  • Cash conversion cycle

Continuous improvement is essential for adapting to market changes. Regular audits and reviews highlight areas for enhancement. This proactive approach ensures that treasury strategies remain effective and aligned with the company's evolving financial landscape.

Practical tips for small businesses, startups, and consultants

  • Use products that you can easily explain to your CEO or board.
  • Don’t chase high yields - treasury is not speculation.
  • Keep a clear liquidity buffer.
  • Diversify across different safe buckets.
  • Never use long-term or volatile instruments for operational cash.

Conclusion: Keep it simple, safe, and structured

Treasury management doesn’t need to be complicated or intimidating. With a few clear principles - safety, liquidity, diversification - any company can turn idle cash into a reliable financial asset.

Traditional tools like MMFs and T-Bills remain essential. Modern tools like digital credit add flexibility, higher transparency, and better short-term yield.

The companies that handle treasury well are the ones that grow with confidence: they stay liquid, stay safe, and let their cash consistently work for them.
