Early payment discounts have existed for as long as trade credit has. The classic 2/10 net 30 arrangement — pay within 10 days and deduct 2%, otherwise pay the full amount within 30 days — is still common in Swiss B2B invoicing. But the traditional model has a significant limitation: the discount terms are fixed at invoice creation and apply uniformly to every payment, regardless of when exactly it arrives or how much working capital either party needs at that moment.
Dynamic discounting changes this. Instead of a binary choice between the early payment discount and the standard terms, it opens up a sliding scale: pay earlier, get a bigger discount. The economics adjust continuously based on when payment actually happens. And it only works reliably when invoices arrive as structured electronic documents that systems on both sides can process without manual handling.
Why structured invoices are the prerequisite
The logic of dynamic discounting depends on knowing the exact invoice details — amount, due date, payment terms — at the moment they arrive at the buyer's system. With a PDF invoice, this information is extracted by a human or by OCR software, both of which introduce delay and potential errors. By the time the invoice is approved and entered into the buyer's ERP, several days may have passed, narrowing the window for early payment.
A structured e-invoice — delivered via PEPPOL or through an integrated AP platform — arrives directly in the buyer's system with payment terms and due dates as machine-readable fields. The moment the invoice is received, the discount window can be calculated and surfaced to the treasury team. No data entry, no delay.
This is not a theoretical advantage. Platforms that run dynamic discounting programmes report that the average time from invoice receipt to approval drops from 7–12 days with manual processing to 1–2 days with straight-through processing. That gap is several hundred basis points of potential early payment yield, depending on your payment terms.
How the economics work
The appeal of dynamic discounting is that it creates a genuine win on both sides, which is not always the case with working capital tools.
For buyers, early payment under a dynamic discounting programme earns an annualised return on cash. A 1% discount for paying 20 days early is equivalent to an annualised return of around 18%. In a period where short-term cash yields are modest, deploying surplus working capital into supplier discounts can outperform money market rates. Buyers with strong cash positions and reliable cash flow forecasting — utilities, large retailers, public sector bodies with predictable budgets — are natural candidates for running discounting programmes.
For suppliers, the ability to accelerate payment on individual invoices provides liquidity on demand without the cost and complexity of a revolving credit facility. A supplier with a short-term cash need can offer a discount on a specific invoice to get paid in three days rather than 45. The discount cost is knowable and finite. Bank overdraft costs are less predictable and often higher for SMEs without strong credit ratings.
The key difference from traditional factoring or supply chain finance is that dynamic discounting uses the buyer's own cash. There is no third-party financier taking a margin, and no risk of the facility being withdrawn.
Static payment terms vs dynamic discounting: what the invoice carries
In a traditional settlement discount arrangement, the terms appear on the invoice as a text note — "2% discount if paid within 10 days" — or in a standard field like PaymentTerms/Note. The buyer's system may or may not parse this automatically; in many cases a human reads it and decides whether to take the discount.
Dynamic discounting platforms work differently. Instead of encoding the discount schedule on the invoice, they work with the approved invoice amount and due date and run the discounting calculation independently. The supplier agrees to offer invoices into the discounting platform, the buyer's treasury team sees available invoices and the cost of accelerating each one, and payment is triggered through the platform.
From an e-invoicing perspective, the structured invoice plays two roles: it provides the approved invoice data that feeds the platform, and it carries the payment reference that links the eventual payment back to the open item for reconciliation. The camt.054 notification that arrives when the buyer pays carries the same reference, allowing the supplier to close the invoice automatically.
The approval speed bottleneck
The biggest practical barrier to dynamic discounting is invoice approval time, not the discounting mechanics. If a supplier offers a 30-day invoice into a discounting programme, but the buyer's AP team takes 15 days to approve it, there are only 15 days left in which to take an early payment discount. That cuts the yield roughly in half.
This is why AP automation and dynamic discounting are so closely linked. An AP process that approves clean, matched invoices in one to two days — because structured data means there is nothing to re-key or manually verify — creates a wide window for early payment. An AP process that takes two weeks to approve an invoice because someone has to find the original purchase order and chase a department head for sign-off creates almost no window at all.
If you are evaluating a dynamic discounting programme and your current invoice approval cycle is longer than five days, fix the AP process first. The discounting benefit will be marginal until you do.
Practical options for Swiss companies
For buyers running their own dynamic discounting programme, the setup typically involves connecting your AP platform to a discounting module (some ERP systems have this built in) and agreeing terms with suppliers. You need a reliable cash flow forecast, clear treasury policies around how much of your surplus cash to deploy, and a straightforward supplier onboarding process. Suppliers need to be able to see their available invoices and opt in to early payment without significant friction.
For suppliers looking to access early payment from buyers who run programmes, the practical requirement is simply that your invoices arrive in a format the buyer's system can process automatically. If you are already sending structured e-invoices via PEPPOL or eBill and your invoices pass three-way matching without exceptions, you are already set up to benefit from any discounting programme a buyer offers. The discount is usually offered through the buyer's supplier portal, not through the invoice itself.
For SMEs that want the liquidity benefit but whose buyers do not run discounting programmes, there are third-party platforms that connect suppliers to a pool of investors willing to fund early payment in exchange for the discount. These are closer to invoice factoring in structure and typically involve higher transaction costs. The structured invoice data still matters here — platforms that can ingest validated, approved invoice data straight from a PEPPOL or eBill feed process faster and at lower cost than those relying on PDF uploads.
What to look for in your invoicing setup
If early payment discounting is on your agenda as either a buyer or a supplier, the practical checklist is short:
Your invoices should arrive as structured data with the due date and invoice amount as machine-readable fields — not as PDFs where these are read by a human. Your AP approval workflow should be automated enough that clean, matched invoices are approved within two days of receipt. And your payment process should be able to initiate early payment from a treasury instruction without requiring a manual invoice amendment or a new payment run setup.
None of this requires a specialised discounting platform to get started. The infrastructure improvements that enable dynamic discounting — structured invoices, fast approval, clean reconciliation — are the same improvements that reduce invoice processing costs across the board. The discounting programme is an additional return on top of the cost savings, not a separate investment.
