Why payment terms affect liquidity
Working capital measures a company's ability to finance day-to-day operations: the difference between current assets (accounts receivable, inventory, cash) and current liabilities (trade payables, short-term tax and social security obligations). In many Swiss SMEs, trade payables represent one of the most significant — and often underestimated — sources of spontaneous financing.
Extending supplier payment terms means retaining cash longer before settling invoices. With the same collections and inventory levels, every additional day of deferral translates directly into greater cash availability. This is not about delaying payments haphazardly, but about deliberately structuring contractual terms and managing them with accounting discipline.
This guide explains how to calculate the impact on working capital, which negotiation levers to use in Switzerland, which risks to avoid, and how to integrate payment term management into the daily administrative cycle — with tools such as Accountex to monitor due dates, cash flows, and balance sheet position in real time.
Working capital and the cash conversion cycle
Before negotiating more favourable terms, it is essential to understand how payment terms fit into the company's operating cycle:
| Metric | Formula | What it measures |
|---|---|---|
| Net working capital | Current assets − Current liabilities | Short-term operational liquidity reserve |
| DSO (Days Sales Outstanding) | (Accounts receivable ÷ revenue) × 365 | Average collection period in days |
| DIO (Days Inventory Outstanding) | (Inventory ÷ cost of goods sold) × 365 | Average inventory holding period in days |
| DPO (Days Payable Outstanding) | (Trade payables ÷ purchases) × 365 | Average payment period to suppliers in days |
| Cash conversion cycle | DSO + DIO − DPO | Days between cash outflow and cash inflow |
An increase in DPO — with DSO and DIO unchanged — reduces the cash conversion cycle and frees up liquidity. Example: a company with annual purchases of CHF 600,000 that moves from 30 to 45 days of average deferral retains approximately CHF 25,000 more in cash (600,000 ÷ 365 × 15). For businesses with tight margins, the effect is tangible without resorting to external financing.
Most common payment terms in Switzerland
Swiss B2B commerce uses several different contractual formulations. Knowing them allows you to negotiate with precision:
Net payment
Terms such as "net 30 days", "net 60 days", or "payable within 30 days of invoice date" indicate the due date without discount. They are the most transparent contractual basis and the easiest to monitor in accounting.
Watch out for end-of-month formulations: "payable at end of month following invoice month" (e.g. invoice dated 5 January with due date 28 February) can add up to nearly 30 days compared to "net 30 days" from invoice date (due date ~4 February). "30 days after end of month" follows different calculation rules: always verify the contractual wording.
Skonto (early payment discount)
Typical terms: "2% within 10 days, net 30 days" (2/10 net 30). Skonto is very common in Switzerland and represents an implicit financing cost for those who pay after the discounted deadline.
Before extending net terms, calculate whether skonto is worthwhile: a 2% discount over 10 days equates to an effective annual rate of approximately 37%. Forgoing skonto to gain 20 days of deferral may not be economically advantageous.
Advance payment or cash
Required mainly by new suppliers or in sectors with high insolvency risk. It reduces available working capital, but may justify price discounts or delivery priority.
Assess whether the business relationship allows a gradual transition to deferred terms after a period of mutual trust.
Instalment plans and partial payments
For major purchases (machinery, IT projects), suppliers may accept down payments plus a final balance. This does not extend overall DPO, but spreads cash outflows over time.
Document each tranche with precise due dates and record down payments as prepayments or partial liabilities, depending on when economic risk transfers.
How to negotiate longer terms without damaging the relationship
Extending payment terms is a commercial negotiation, not an administrative workaround. Suppliers assess insolvency risk, business volume, and past payment regularity. A structured approach increases the likelihood of success:
- Demonstrate solvency: share up-to-date financial statements or bank statements with strategic suppliers. Transparency reduces perceived risk and justifies more favourable terms.
- Offer volume or multi-year commitment: a framework agreement with purchase forecasts can be exchanged for 45- or 60-day deferrals instead of the usual 30.
- Propose a compromise on skonto: if the supplier insists on 2/10 net 30 terms, negotiate "1.5% within 10 days, net 45 days" — a balance between financing cost and liquidity.
- Standardise internally: define a company policy (e.g. DPO target of 40 days for non-critical suppliers) and apply it consistently, avoiding arbitrary exceptions that undermine credibility.
- Pay on time: meeting agreed deadlines is a prerequisite for future negotiations. Systematic delays damage the relationship and can lead to worse terms or suspension of deliveries.
Risks to avoid when extending DPO
Every additional day of deferral involves trade-offs that must be evaluated carefully:
| Risk | Consequence | How to mitigate |
|---|---|---|
| Loss of skonto | High implicit financing cost | Calculate the effective annual rate; pay within skonto terms for high-volume suppliers |
| Relationship deterioration | Higher prices, low priority, restrictive terms | Proactive communication; on-time payments; volume as leverage |
| Supply chain disruption | Delivery delays or order blocks | Diversify critical suppliers; do not push beyond reasonable limits |
| Cash cycle imbalance | Slow collections + long payments = accumulated liabilities | Monitor DSO and DPO jointly; align customer and supplier policies |
| Default interest | Art. 104 CO: 5% per annum (minimum statutory rate; agreements for a lower rate are invalid) | Meet deadlines; explicitly negotiate any exceptions |
| Signals of financial distress | Perceived by banks, auditors, and business partners | Document the strategy; maintain a liquidity reserve |
Accounting and tax impact in Switzerland
Trade payables appear under current liabilities on the balance sheet. Under Swiss accounting rules (Code of Obligations, Art. 957 et seq., and GAAP/FER for SMEs), received invoices must be recorded at the time of economic accrual — regardless of the actual payment date. Extending contractual terms does not change cost recognition, but shifts the cash outflow over time.
For VAT, input tax deductibility follows the standard rules: the supplier invoice must be compliant (VAT number, amounts, period). The timing of payment does not affect the deduction, provided the invoice is valid and correctly recorded in the relevant accounting period.
At year-end, verify that all received but unpaid invoices are recorded as trade payables. Omissions understate both costs and current liabilities, distorting net working capital and liquidity ratios presented to banks or investors.
Typical accounting entries
On receipt of invoice: debit expense account (e.g. 4000 Materials purchased) + debit recoverable VAT (1170) / credit trade payables (2000).
On payment: debit trade payables (2000) / credit bank or cash (1020). Contractual deferral requires no additional entries: the liability remains on the balance sheet until settled.
Operational strategy for SMEs: from calculation to action
A structured plan avoids reactive decisions and allows you to measure results:
- Map suppliers by criticality: classify them as strategic (sole supplier, critical components), important (high volume), and replaceable. Focus negotiations on the second and third groups.
- Calculate current DPO and target: extract average trade payables and annual purchases from accounting. Set a realistic target (e.g. +10 days over 12 months).
- Simulate the impact on liquidity: translate additional days into Swiss francs and compare with projected cash requirements for payroll, VAT, taxes, and investments.
- Negotiate and formalise: every new term must be documented in writing (purchase order, framework agreement, or addendum). Update due dates in accounting systems.
- Monitor monthly: compare actual DPO against target, check upcoming due dates, and maintain a liquidity buffer for strategic suppliers you pay on time.
Quick checklist before changing terms
- ✓Is the average customer DSO compatible with the target DPO? An excessive gap signals liquidity tension.
- ✓Have you calculated the effective cost of forgoing skonto with key suppliers?
- ✓Have the new terms been agreed in writing with every affected supplier?
- ✓Does the cash flow plan cover at least 90 days of outflows, including payroll and tax obligations?
- ✓Are all received invoices correctly recorded, including those awaiting payment?
- ✓Is there an internal policy defining who approves exceptions to standard terms?
- ✓Are strategic suppliers given payment priority, regardless of average deferral?
