Payment Terms
Payment terms are the contractually agreed rules by which an invoice must be settled — above all the payment period, payment method, early-payment discount and consequences of default. They define by when, how and on what conditions the invoice amount falls due.
Payment terms are the rules agreed between seller and buyer for how an invoice is to be paid. They answer the questions: by when must the amount reach the supplier (payment period), by what means is payment made (payment method), is there a price reduction for fast payment (early-payment discount, "Skonto") and what happens if payment is not made on time (default)? As part of the contractual and delivery terms, they appear on the quote, order confirmation and invoice and form the basis for the entire payment process.
A classic payment term reads, for example, "Payable within 30 days net, 2% discount if paid within 10 days." It combines a net period (30 days) with a discount period (10 days) and a discount rate (2%). Payment terms are not a purely commercial detail: they directly govern the liquidity of both sides, influence the effective price of a transaction and help decide how quickly a receivable actually turns into cash.

Components of payment terms
Payment terms are made up of several elements that together form the complete payment agreement. The most important is the payment period: the deadline within which the invoice amount is to be paid without deduction — common values are "immediately", 14, 30 or 60 days net from the invoice or delivery date. It is often supplemented by an early-payment discount agreement, that is, a percentage reduction for payment within a shorter period. Added to this are the payment method (bank transfer, direct debit, credit card, prepayment, invoice, cash on delivery) and rules for the event of default such as default interest or dunning fees.
Payment period and early-payment discount
The payment period and the early-payment discount form the commercial heart of the terms. The payment period defines the latest payment date; the discount rewards earlier payment with a deduction. What matters is the reference date ("discount basis"): deadlines run from the invoice date, the invoice receipt date or the delivery date — depending on the agreement. An effective interest rate can be derived from the discount period: a 2% discount for paying 20 days earlier corresponds to a very high annual rate, which is why taking the discount is almost always worthwhile.
Payment method and default rules
The payment method defines the payment channel and helps determine the risk of default and the effort involved: prepayment minimises the seller's risk, while purchase on account raises conversion in commerce but shifts the risk onto the supplier. Default rules take effect when the payment period is exceeded — in B2B, statutory default in Germany occurs at the latest 30 days after the amount falls due and the invoice is received, regardless of any reminder.
Why payment terms matter
Payment terms are a direct lever on liquidity. A longer payment period that a supplier grants its customers ties up capital, because the receivable stays open longer; conversely, a long period on the purchasing side gives the buyer a financing advantage. Designing payment terms is therefore an instrument of working-capital management: it influences the average receivables period (Days Sales Outstanding) as well as the payables period.
At the same time, payment terms are a pricing instrument. An early-payment discount is economically a price reduction, and a long payment period is a hidden supplier credit. Anyone granting generous periods in sales should price in their financing cost; anyone negotiating in purchasing can lower the effective price via payment terms without touching the list price. Clearly defined terms also reduce disputes: due date, discount deduction and default consequences are unambiguously governed and can be checked automatically.
Payment terms in the ERP system
In an ERP system or inventory management system, payment terms are maintained as reusable condition keys and assigned to the master data. Stored on the customer master, they flow automatically into the quote, order and invoice; on the supplier master, they govern the evaluation of incoming invoices and the payment scheduling. From these, the system automatically calculates the net due date, discount period and discount amount and carries these values into the open-item management.
The benefit unfolds in automation: from the stored payment period, the ERP determines the due date of each open item and thereby controls dunning runs and payment forecasting. On incoming payments, it checks whether payment was made within the discount period and posts the discount deduction automatically. For outgoing payments, the payment scheduling generates proposals that make due supplier invoices ready for payment by SEPA transfer at exactly the optimal date — ideally while taking advantage of the discount.
Distinction: payment terms vs. delivery terms
Payment terms must be distinguished from delivery terms. While payment terms govern how and when payment is made, delivery terms determine how and when delivery takes place — in particular, who bears the transport costs and risk. In international trade, the latter are standardised via the Incoterms. Although both belong to the general terms and conditions, they concern different levels of the transaction.
The concept must likewise be distinguished from the early-payment discount and the payment period, which are merely individual components of the payment terms: the payment period is the deadline, the discount is the reduction for early payment — the payment term is the overarching agreement that encompasses both and more. Finally, payment terms should not be confused with the payment method alone: the payment method is only one of several parameters within the payment terms.
DACH specifics and legal framework
In the German-speaking region, payment terms are framed by statutory requirements. In Germany, § 271a BGB limits the permissible length of contractual payment periods — in B2B, periods over 60 days are only effective under strict conditions, and even stricter limits apply towards public-sector clients. Without an express agreement, the payment is generally due immediately upon receipt of the invoice.
For default, § 286 BGB applies: in a transaction between businesses, default occurs at the latest 30 days after the amount falls due and the invoice is received, even without a reminder. Default interest in B2B is nine percentage points above the base rate, plus a flat fee of 40 euros. Austria and Switzerland have comparable but differing rules. Payment terms should therefore be worded in a legally sound way and stored in the ERP so that due dates and default consequences are calculated correctly.
Example
Payment terms in B2B trade
A wholesaler agrees with a regular customer on the payment term "30 days net, 2% discount if paid within 10 days". In the ERP, this condition key is stored on the customer master and flows automatically into every invoice. For an invoice of 10,000 euros, the system calculates two dates: the discount due date after 10 days with a 200-euro deduction, and the net due date after 30 days for the full amount.
The customer pays 9,800 euros on the eighth day. The automatic payment reconciliation recognises the payment within the discount period, posts the 200 euros as discount expense and clears the open item in full. Had the customer paid only after 30 days, the full amount would have been due; from the 31st day, the ERP would have flagged the item as overdue and triggered the dunning run.
