The Treasurer: A Strategic Guardian of Financial Stability

In large corporations, the treasurer sits near the top of the finance function, managing billions in liquidity, hedging currency exposure, and negotiating with a syndicate of banks. Most small and medium-sized businesses have no such person — and yet every single one of them has a treasury function, whether anyone calls it that or not. Someone decides which supplier gets paid this week. Someone watches the bank balance before signing a new lease. Someone worries, at 2 a.m., about whether the big client's payment will land before payroll.

That someone is usually the owner. This article looks at what the treasury function actually involves, how to run it deliberately rather than by instinct, and how the role is changing as tooling takes over the mechanical parts.

Who Is the Treasurer in an SMB?

In a business with no dedicated finance team, treasury responsibilities are scattered by default: the founder checks the bank app in the morning, the office manager chases late invoices, the external accountant sees the picture months later. Nothing is written down, and nobody owns the whole.

As companies grow, the function typically consolidates in stages:

• Up to roughly 10–20 people: the owner-manager is the treasurer, usually without the title and often without the method.
• Growing SMBs: a bookkeeper, office manager, or finance assistant takes over daily payments and collections, while the owner keeps the strategic decisions.
• Established mid-sized firms: a finance manager or CFO absorbs treasury among other duties; only at significant scale does "treasurer" become a full-time job.

The important insight is that treasury is a function, not a headcount. It exists in your business today. The only question is whether it is performed deliberately — with an owner, a rhythm, and a forecast — or reactively, one bank-app refresh at a time.

Profitability is an opinion shaped by accounting conventions; cash is a fact. The treasurer is the person in the business whose job is to deal in facts.

Core Responsibilities of the Treasury Function

1. Liquidity Management

The first duty is brutally simple: make sure the company can pay what it owes, when it owes it. That means knowing the current cash position across all accounts, knowing what is due in and out over the coming weeks, and maintaining a buffer for surprises. A common rule of thumb for SMBs is to hold a reserve covering at least two to three months of fixed costs — enough to absorb a lost client or a late-paying quarter without panic decisions.

Liquidity management also means putting excess cash to work sensibly (short-term deposits rather than idle balances) and arranging access to credit — an overdraft facility or credit line — before it is needed. Banks lend most willingly to companies that do not urgently need the money.

2. Cash Flow Forecasting

The treasurer's defining tool is the forecast. Two horizons matter:

• Short-term (4–13 weeks), week by week: built from actual invoices due, payroll dates, VAT and tax deadlines, and loan repayments. Its job is to spot the specific week where cash dips dangerously — while there is still time to act.
• Medium-term (12 months), month by month: built from the budget and known seasonality. Its job is to inform decisions: can we hire in March, buy the machine in June, take the fitting-out loan now?

A worked example: a distribution business sees on its 13-week forecast that week 7 combines quarterly VAT, payroll, and a large supplier payment, producing a projected dip €18,000 below zero. Because the gap is visible five weeks ahead, the fix is easy — offer a 2% early-payment discount on two large customer invoices and shift the supplier payment one week with a phone call. Discovered in week 7 itself, the same gap becomes an emergency overdraft and a damaged supplier relationship. Forecasting does not change the future; it changes how early you get to react to it.

3. Banking Relationships

The treasurer owns the relationship with the bank — or better, with two. That includes negotiating fees and terms, keeping the bank informed (bankers hate surprises far more than they hate bad news), reviewing account structures, and periodically testing the market. A second banking relationship, even a minor one, is cheap insurance: it provides a fallback if your main bank tightens credit, and negotiating leverage every time terms come up for renewal.

4. Payment Security and Controls

Treasury is also the front line against fraud and error. SMBs are prime targets for invoice fraud and "CEO fraud" (urgent payment requests impersonating an executive). Basic controls cost little and prevent disasters:

• Verify any change to a supplier's bank details by phoning a known contact — never by replying to the email that requested it.
• Require dual approval for payments above a defined threshold.
• Separate duties where headcount allows: the person who enters invoices should not be the only one who approves payments.
• Review bank access rights whenever someone joins or leaves.

5. FX Basics

Any SMB that buys or sells outside its home currency carries exchange-rate risk. A European importer agreeing to pay $100,000 in 90 days does not know today what that will cost in euros. The treasury function's job is not sophisticated speculation — it is the opposite: remove the uncertainty. Simple tools include invoicing in your own currency where you have the negotiating power, natural hedging (matching dollar revenues against dollar costs), holding a foreign-currency account to time conversions, and forward contracts that lock in a rate for a known future payment. The goal is that currency moves never decide whether a deal was profitable.

The Treasury Rhythm: Daily, Weekly, Monthly

Good treasury is less about brilliance than about cadence. A workable rhythm for an SMB:

Daily (5–10 minutes)

• Check balances across all accounts.
• Confirm expected large receipts arrived; flag any that did not.
• Release the day's approved payments.

Weekly (30–60 minutes)

• Update the 13-week rolling forecast with actuals.
• Review aged receivables and trigger collection calls on overdue invoices.
• Plan the coming week's payment run and check it against available cash.

Monthly (1–2 hours)

• Compare last month's forecast to what actually happened, and improve the assumptions behind the biggest misses.
• Refresh the 12-month projection.
• Review bank fees, credit-line usage, and covenant headroom.
• Brief the management team (or, in a one-person show, take a deliberate step back) on the cash outlook.

The monthly forecast-versus-actual review deserves emphasis: it is how a forecast stops being a spreadsheet of hopes and becomes an instrument you can trust. If customers systematically pay 15 days later than assumed, the review catches it and the next forecast is honest about it.

KPIs the Treasurer Watches

A handful of indicators cover most of what matters in an SMB:

• Cash position — total available cash across accounts, today.
• Cash runway — months of survival at current net burn if inflows stopped growing; the single most sobering number in a downturn.
• DSO (Days Sales Outstanding) — average days customers take to pay. If your terms say 30 and your DSO says 55, your customers are financing themselves with your money.
• DPO (Days Payable Outstanding) — average days you take to pay suppliers. Paying dramatically faster than you collect is generous, and expensive.
• Cash conversion cycle — DSO plus days of inventory minus DPO: how long a euro stays trapped in operations before returning as cash. Shortening it releases funding no bank has to provide.
• Forecast accuracy — how far last month's projection missed reality; the health check on your whole treasury process.

How Tooling Changes the Job

Historically, SMB treasury meant logging into several bank portals, exporting statements, and rebuilding a fragile spreadsheet every week — hours of mechanical work that produced a snapshot already out of date. The tedium is precisely why so many owners skipped it and flew blind.

Modern cash-management software removes the mechanical layer. Trezy, for example, connects to more than 2,000 banks, so all balances and transactions consolidate automatically into one live view; its AI builds a rolling 12-month cash flow forecast from your actual patterns; and setup takes about five minutes, with a free plan and paid plans from €7.50 per month — a fraction of the cost of the spreadsheet hours it replaces, and a 7-day trial to see it on your own numbers.

What tooling changes is not the responsibility but the altitude. When consolidation and projection are automatic, the daily check takes two minutes instead of twenty, and the hours saved move up the value chain: negotiating better terms, deciding when to invest, stress-testing scenarios ("what if our biggest client pays 30 days late?"), and building the buffer before the storm. The machine handles the bookkeeping of the future; the human makes the judgment calls.

Writing a Simple Treasury Policy

Larger companies formalize the treasury function in a policy document. An SMB does not need thirty pages, but writing down a few rules — even one page — turns good intentions into a system that survives busy weeks and staff changes. A minimal policy answers five questions:

• What is our minimum cash buffer? Pick a floor — commonly expressed as a number of weeks of fixed costs — below which the balance must not fall without triggering action. The right level depends on how volatile your receipts are and how quickly you could draw on credit.
• Who can move money, and up to what amount? Define payment approval thresholds: for example, one signature up to a set amount, two signatures above it, and a named backup approver for holidays. This is your single best defence against both fraud and error.
• Where do we keep surplus cash? Decide in advance how much stays in the operating account, what goes to a savings or term account, and at what threshold you review it — so surplus is a deliberate choice rather than an accident.
• How do we handle new counterparties? A simple verification step for new supplier bank details, and a callback rule for any request to change payment details, closes off the most common invoice-fraud scenarios.
• When do we escalate? Define the events that trigger an immediate conversation with the bank or your accountant: the forecast showing a breach of the cash floor, a covenant at risk, or a major customer missing a payment date.

Review the policy once a year. The document matters less than the conversation it forces: agreeing these rules while things are calm is infinitely easier than improvising them mid-crisis.

The Guardian Role, in Practice

Calling the treasurer a "strategic guardian of financial stability" sounds grand for someone reconciling bank feeds on a Tuesday morning. But the title is earned. Businesses rarely die of bad products; they die of running out of cash — often while still profitable on paper. The treasury function, however modest its scale, is the discipline that prevents exactly that.

If you run a small business, the practical conclusion is simple: appoint a treasurer, even if it is yourself for one focused hour a week. Give the role a rhythm (daily glance, weekly forecast, monthly review), a handful of KPIs, and tools that do the mechanical work. You will make the same decisions you make today — hiring, investing, borrowing — but you will make them with headlights on. That is what financial stability actually is: not the absence of risk, but the ability to see it coming.
