5 Cash Optimization Techniques Every CFO Should Know in 2026

Most cash optimization advice aimed at CFOs is either obvious ("collect faster") or academic ("optimize your working capital cycle"). Neither helps when you are sitting in front of a board deck on Sunday night, staring at a €4M idle cash balance that earned exactly nothing last year, and trying to decide whether to push DPO out another five days or finally sign that supply chain finance term sheet that has been on your desk since Q3. This article skips the theory. Five techniques, real numbers, the order to deploy them, and the specific moments where each one quietly destroys value if you do it wrong.

The 5 techniques as compounding wins

Treasury optimization is rarely about one heroic move. It is about five or six adjustments that each free 20–80 bps of margin or release a few weeks of working capital, and which compound into something material. A €30M revenue mid-market group running €4M average idle cash earned €0 in 2024 — at today's overnight rates, that is €120 000–€140 000 left on the table per year. Add another €200 000 from dynamic discounting, €350 000 from a clean DPO stretch, and €150 000 from a netting cycle, and you have moved EBITDA by close to a percentage point without touching pricing, headcount, or the commercial pipeline.

The five techniques in this article are ranked roughly by ratio of impact to effort, but the right order for your group depends on whether you have idle cash, a long supplier tail, a multi-entity footprint, or all three. We will get to a prioritization table at the end. First, the techniques themselves — including the ways each one can backfire.

1. DPO optimization without supplier damage

Every CFO knows that pushing payment terms releases working capital. Fewer know how to do it without quietly poisoning the supplier base — which is a problem you only discover the day a critical single-source vendor decides you are not worth the trouble and gives you 30 days' notice. The trick is segmentation, not blanket policy.

Segmenting the supplier book

Before you touch a single payment term, segment the AP ledger into four buckets. For a typical €30–€80M revenue mid-market group, the distribution looks roughly like this:

• Strategic / single-source (5–10% of spend): the supplier you cannot replace inside six months. Touch their terms and they will price the abuse back into the next renewal, or worse, deprioritize you in an allocation event. Leave alone — or actually shorten their terms in exchange for a discount.
• Tier-1 commodity (40–50% of spend): large, multi-source, financially resilient suppliers who can absorb a 15–30 day stretch without pain. This is where 80% of your DPO gain lives.
• Tier-2 long tail (30–40% of spend): hundreds of small invoices. Stretching them produces marginal cash and disproportionate noise. Standardize terms instead.
• Fragile / SME suppliers (5–10%): small businesses for whom your payment is a meaningful share of their working capital. Stretch them and you inherit their cash flow problem two quarters later. Pair these with supply chain finance (technique 3) instead of a stretch.

The graceful stretch

For Tier-1 commodity suppliers, the move is what treasury practitioners call the graceful stretch: extend at renewal, not mid-contract; align with a clear communication ("we are harmonizing terms across the group to net 60"); and bundle it with something the supplier wants — volume commitments, multi-year scope, or a faster onboarding for new SKUs. Done well, a 30→60 day stretch on €15M of Tier-1 spend releases roughly €1.25M of one-time cash and roughly €50 000–€70 000 of annualized financing benefit at current rates.

We pushed DPO from 42 to 58 days across the board in 2022. Released €3.4M. By Q2 2023, three of our top fifteen suppliers had quietly moved us off their priority allocation list. We got the cash. We also got a six-month delivery delay on a critical SKU during an upcycle. Net-net, it cost us more than it released.

2. Dynamic discounting — the math nobody runs

Dynamic discounting is the highest-return, lowest-risk trade in the entire CFO toolkit, and the majority of mid-market groups still leave it on the table. The mechanism is trivial: a supplier offers a discount for early payment (the classic is 2/10 net 30 — take 2% off if you pay in 10 days instead of 30), and you decide on an invoice-by-invoice basis whether the implied yield beats your cost of cash.

The reason it gets ignored is that 2% looks small. It is not small. It is an annualized return calculated as follows:

Read that again. A 2/10 net 30 invoice you choose to pay early is earning you a risk-free, fully collateralized 37% annualized return. Your overnight cash is earning 3.2%. There is no other instrument on the balance sheet that comes close, and it is sitting in your AP module right now, unused, because nobody has the authority — or the discipline — to act on it invoice by invoice.

What the math actually looks like

On a €40M annual AP spend with roughly 25% of suppliers offering discount terms and a 60% take-up rate, this trade routinely produces €150 000–€220 000 of pure margin per year. The reason most groups capture maybe 10% of it is operational: discount terms are buried in PDFs, AP clerks pay on net date by default, and there is no dashboard showing the partial-month opportunity cost of paying late.

The tradeoffs

• Cash availability: dynamic discounting consumes cash. If you are tight on liquidity, the implicit cost of the discount is your incremental borrowing rate, not your overnight rate. At 6% RCF cost, 2/10 net 30 still wins; at 11% mezzanine cost, 1/10 net 60 may not.
• Supplier-funded vs. third-party-funded: a true dynamic discounting platform (Taulia, C2FO, Coupa Pay) lets you propose dynamic terms — pay on day 5 for 1.0%, day 10 for 0.7%, day 15 for 0.4%. The APR sliding scale is yours to set.
• Don't cannibalize SCF: if you are running supply chain finance (next section), dynamic discounting and SCF compete for the same supplier wallet. Pick one channel per supplier.

3. Supply chain finance — reverse factoring at scale

Supply chain finance (SCF), also called reverse factoring or confirming, is the institutional cousin of dynamic discounting. The structure: a tier-1 bank (BNP Paribas, Santander, ING, Citi, HSBC) buys your approved invoices from your suppliers at a discount, pays the supplier early, and collects from you on the original net date. The supplier gets early cash priced at your credit rating, not theirs — which for a SME supplier of a €100M corporate is typically a 300–600 bps reduction on their financing cost.

What it costs and what it pays

For the buyer (you), an SCF programme costs typically 50–100 bps in arrangement and ongoing fees, sometimes embedded in the bank's overall relationship pricing rather than charged separately. In exchange you get four things:

1. Term extension without supplier pain: the canonical play. You stretch payment terms from 45 to 75 days. Suppliers who would normally complain are made whole because they can draw early through the SCF facility at a rate that is better than their existing factoring or RCF.
2. Off-balance-sheet treatment (sometimes): if structured correctly, SCF payables remain trade payables and do not flip to debt classification. This is now under heavy IFRS scrutiny — IAS 1 disclosure requirements tightened in 2024 — but with a clean structure it still works.
3. Supplier risk reduction: your fragile SME suppliers (bucket 4 from technique 1) become financially healthier because they get reliable early cash. You inherit a more resilient supply chain.
4. ESG narrative: if your SCF programme is structured to favor suppliers in sustainability programmes, this becomes a sustainability-linked financing line. Useful in your annual report, occasionally useful in your covenant pricing.

The pitfalls

• IFRS reclassification risk. If the SCF programme is too aggressive — terms extended dramatically beyond market, or the bank's recourse pattern looks debt-like — auditors can reclassify the payables as bank debt. This blows up leverage covenants. Get your auditor in the room before you sign the term sheet.
• Concentration with one bank. SCF concentrates AP funding with a single bank. If that bank tightens lines (as several did in March 2023), suppliers lose access overnight. Run two banks if your programme is large enough.
• Supplier onboarding drag. Plan for 6–12 months from term sheet to 50% supplier adoption. KYC on every supplier is the bottleneck.

4. Intercompany netting — for any group with three or more entities

If your group consists of three or more legal entities transacting with each other — typical for any multi-country mid-market business — you are almost certainly leaking cash through intercompany flows. The leak has three sources: FX spreads on each conversion, transaction fees on each cross-border payment, and float costs from days of in-transit cash that earns nothing.

Bilateral vs. multilateral netting

Bilateral netting means entity A and entity B settle their two-way position once a month: instead of A paying B €1.2M and B paying A €1.0M, B pays A a net €0.2M. Citi and JPM both run mature bilateral netting platforms; smaller relationship banks offer simpler versions.

Multilateral netting generalizes this across the whole group. Twelve entities with a tangled web of receivables and payables collapse, on a fixed netting day each month, into a small number of net positions paid to or received from a central netting entity. A typical European mid-market group with eight entities and €60M of annual intercompany flow finds that gross flows compress to €15–€20M of net flows — a 65–75% reduction.

The FX hedging side benefit

Once you net, you also concentrate FX exposure at a single point. Instead of twelve entities each running their own ad-hoc forward contracts (or worse, no hedging at all), the netting center sees the consolidated exposure and hedges once. This typically reduces FX hedging cost by another 10–20 bps because the netting center gets institutional pricing on larger blocks, and reduces over-hedging — which is the most common FX mistake in decentralized treasuries.

Setup effort

• Bank platform selection (Citi, JPM, BNPP, Deutsche): 2–3 months
• Legal documentation across entities (intercompany agreements, netting agreements): 3–4 months
• Tax structuring and transfer pricing: 2–3 months in parallel
• ERP integration for IC invoice feeds: 2–4 months
• First netting cycle: typically 6–9 months from kickoff

Total setup cost for a mid-market group: €80–€150k in legal and advisory, plus internal team time. Annual savings on a €60M IC flow group: €250–€450k. Payback in year one.

5. Sweep accounts and money market funds — the easiest €100k you will ever earn

This is the most embarrassing technique to leave on the table, because it requires zero supplier negotiation, zero ERP work, zero tax restructuring, and roughly two weeks of effort. And yet a startling number of mid-market groups in 2026 are still running large operating balances at 0% on a current account because "we've always banked there."

How sweeps work

A sweep account automatically moves balances above a defined floor — say €500k for operational liquidity — into an overnight investment vehicle each evening, and sweeps them back the next morning. The investment vehicle is typically:

• Bank overnight deposit: simplest, currently around 2.8–3.2% on EUR for mid-market relationships, no credit risk beyond the bank itself.
• EUR money market fund (MMF): AAA-rated, daily liquidity, currently yielding 3.0–3.5% net of fees. Underlying investments are short-dated commercial paper, T-bills, and bank deposits. Constant NAV (CNAV) MMFs trade at exactly €1 per share, fluctuating only the yield.
• Term deposits laddered: for the portion of cash you know you won't need for 30 / 60 / 90 days, ladder term deposits at 3.4–3.8% for another 20–40 bps.

We had €11M average idle cash earning 0.4% on a current account in 2023. Took us eleven business days to set up an MMF sweep with our existing bank. In year one we earned €310k that the prior CFO had simply been giving away. The board asked why nobody had done it before. The honest answer was: nobody asked.

When to deploy each instrument

Prioritization — which to do first

Five techniques, finite treasury bandwidth, a board that wants to see results before the next quarterly review. The right sequence depends on three things: your liquidity position today, the size of your IC flows, and how exposed your supplier base is. The table below ranks the techniques by effort versus impact for a typical €30–€100M revenue mid-market group.

The sequence we recommend

1. Week 1–2: sweep accounts and MMFs. No excuse. If your bank can't set this up in 10 business days, your bank is the problem.
2. Month 1–2: map dynamic discount opportunities in the AP ledger. Build a simple decision rule: take any discount with implied APR > 12%. Start executing manually if needed; automate later.
3. Month 2–4: segment the supplier book. Identify the Tier-1 commodity bucket and queue them for term renegotiation at next contract renewal. Identify single-source suppliers and explicitly protect their terms.
4. Month 4–9: if IC flows justify it (above ~€30M), launch netting structuring with bank, tax, and legal in parallel.
5. Month 6–12: if AP scale justifies it, evaluate SCF — but only after you have your supplier segmentation and dynamic discounting baseline. SCF on top of an unsegmented book is just an expensive way to confuse your suppliers.
