Improving cash flow rarely means generating more revenue — it means getting the money that is already in the business to become available sooner and more predictably. Most effective levers free up capital that is already tied up, rather than raising new financing: they work without adding to the company’s debt.
This guide sets out the concrete measures a finance lead can use to materially improve the cash position of a mid-market business — from days sales outstanding through payment terms and tied-up capital to the financing levers everyone knows about but should use deliberately. The common thread is sequence: pull the cheap, internal levers first, then reach for external financing. How all of this comes together in an ongoing forecast is covered in the cash flow forecasting guide.
The levers at a glance
Before the individual measures, the map helps. Improving cash flow comes down to five levers — four of them free up internal capital at no financing cost, the fifth bridges short squeezes deliberately.
| Lever | How it works | New debt? |
|---|---|---|
| Receivables (DSO) | Invoice and collect faster — the money is already owed to the business. | no |
| Payment terms (DPO) | Use agreed terms in full, without giving up early-payment discounts. | no |
| Tied-up capital | Reduce inventory and work in progress that lock up capital. | no |
| Payment timing | Schedule large outflows deliberately into cash-strong weeks. | no |
| Financing lines | Use the overdraft facility and factoring deliberately, for short squeezes. | maybe |
The first four levers are the core of working capital — they increase cash under the company’s own power. That is exactly why it pays to exhaust them before reaching for a new credit line.
Collect receivables faster (DSO)
The fastest and cheapest lever almost always sits with receivables. Every day an invoice stays open longer is money the business is owed but doesn’t have in the bank. Days sales outstanding (DSO) is the metric for this, and it is directly actionable:
- Invoice immediately, not in batches. Issue invoices on the day the work is delivered, not bundled at month-end. Every day earlier is a day earlier in cash receipts.
- Clear payment terms and deposits. A clear due date on every invoice; on larger orders, deposits and staged billing tied to project progress.
- Consistent collections. Fixed stages with fixed deadlines, triggered automatically — not by gut feel. An overdue invoice is the most expensive form of customer financing there is.
- Early-payment discounts, used with judgment. An early-payment discount pulls receipts forward; it only pays off if the interest saved exceeds the discount given up.
How these pieces come together as a reliable process is covered in the accounts receivable management guide. To give a sense of scale: in this illustrative example, at €12m revenue each day of DSO ties up roughly €33,000 of cash, so five fewer days frees up a six-figure sum — generic example values, not real figures.
Using payment terms and timing payments (DPO)
The flip side of receivables is payables. Days payable outstanding (DPO) measures how long you take to pay suppliers. Using agreed payment terms in full is legitimate and costs nothing — as long as it doesn’t forfeit an early-payment discount or strain a supplier relationship. The skill is balance: stretch the term where it costs no discount, and pay early where the discount earned beats the cost of financing.
Closely related is payment timing. Outflows that are not operationally urgent — an investment, a one-off payment, a large purchase — can often be shifted by days or weeks without causing harm. Scheduling them into a cash-strong week instead of an already-tight one eases the squeeze without a single extra euro flowing. The precondition is knowing which weeks are tight ahead of time — which is exactly what a weekly forecast delivers.

Every business ties up capital between purchasing and cash receipt — in raw materials, finished goods and work in progress. That capital isn’t available as cash while it sits in the warehouse or on the shop floor. Reducing it is one of the strongest levers, because it keeps working permanently:
- Lean inventory. Review safety stock regularly, work down slow-moving and obsolete items, and size orders to actual need rather than to discount thresholds.
- Shorter work in progress. The faster a job moves from the workbench to an invoice, the shorter capital stays tied up. Staged invoicing tied to milestones pulls the cash receipt forward.
- Synchronize buying and selling. Where purchasing runs too far ahead of sales, inventory builds up and absorbs cash — particularly during growth phases.
Together with DSO and DPO, these three points are the core of working-capital management. They determine the cash conversion cycle — the stretch of time between paying for purchases and receiving cash from the customer that the business has to pre-finance. The shorter that cycle, the more cash is free. The metrics and how they interact are covered in depth in the working capital guide.

Using financing levers deliberately
Once the internal levers are exhausted and a short squeeze remains, financing lines come into play — deliberately, as a buffer, not as a permanent state:
- The overdraft facility. The classic buffer for a short shortfall. The precondition is knowing how much of the facility is genuinely free — not the agreed limit, but what remains undrawn after every current charge against it.
- Factoring. Where receivables are structurally high, selling them brings cash receipts forward and eases working capital permanently. This is more of a structural decision than an ad-hoc lever — with a cost that should be weighed against the cash gained.
The difference between an expensive and a calm use of these levers is timing: a business that sees a gathering squeeze weeks ahead negotiates a facility calmly and uses it as planned. One that only notices it on the bank statement pays a premium for being under time pressure. Which is why the foundation of every one of these measures is the same: a rolling weekly view of cash flows. For what to do about a squeeze that is already here, see the cash flow shortage guide.
The common denominator across all seven levers is visibility. Only once expected receipts and payments sit in front of you week by week can you see which lever applies in which week — and steer with the calm, cheap levers rather than the expensive ones under pressure.
