In classic invoices, you often encounter them: cash discount or early payment discount. But what if you switch to e-invoicing or invoice through the Peppol network? Does that discount remain? Is it supported in the digital format? And how do you pass them correctly in a machine-readable invoice?
What can you read on this page?
What is an early payment discount?
A financial discount or cash discount is a discount your customer receives when they pay faster than the normal payment deadline. For example:
Invoice amount: €1,000
Cash discount: 2% if paid within 10 days
Normal payment term: 30 days
If the customer pays within the 10 days, he pays €980. If he pays later, then the full amount of €1,000 applies.
Note that this is not cash, but a financial incentive for faster payment.
VAT processing at financial discount (cash discount)
Here is often the biggest pitfall. You always calculate the VAT on the total amount with discount, regardless of whether the customer uses the early payment discount. Working with a credit note is not correct, according to the VAT Code (Article 28, 1°).
Example:
| Description | Amount |
|---|---|
| Total excluding VAT | €100 |
| Financial discount (2%) | €2 |
| Measure of charge | €98 |
| VAT 21%. | €20,58 |
| Total on invoice (without discount) | €120,58 |
| Payable when paid on time | €118,58 |
If the customer pays late, he pays the full amount of €100 + €20.58 VAT = €120.58.
This is a special case of a “discount for earlier payment,” and this is where things often go wrong in e-invoicing if the fields are not filled in correctly.
What is a commercial discount
In addition to financial discount, you can also give a commercial discount. This is a discount on the gross amount and is accounted for in operating income, not as a financial cost as with a financial discount.
A commercial discount can be applied to one product or the total amount; therefore, it does not have to be on the entire invoice.
Example:
| Description | Amount |
|---|---|
| Total price excluding VAT | €100 |
| Commercial discount (2%) | €2 |
| Measure of charge | €98 |
| VAT 21%. | €20,58 |
| Total amount on invoice (with discount, incl. VAT) | €118,58 |
| Payable | €118,58 |
Important difference:
Like a financial rebate, VAT is calculated on the amount after the rebate is applied.
A commercial discount is an acquired discount, once allowed you receive the discount regardless of the quantity of goods you buy or the term in which you pay. You are always entitled to it.
Accounting-wise, the difference is significant: a financial discount is a deductible financial expense, while a commercial discount is part of operating income.
Is cash discount supported in e-invoicing?
Yes. Both UBL (the invoice format on which e-invoicing and Peppol are based) and the Peppol network fully support cash discount. The standard provides specific fields for the discount percentage, period and payment terms so that the discount can be processed correctly by software and is clear to the recipient. In practice, we are that many companies work with credit notes. That is not the correct way to apply a cash rebate.
How do you process cash discount in Peppol format & UBL?
At Peppol, cash discount is included in the payment terms, usually via a text field(PaymentTerms / PaymentTermNote). This includes, for example, the discount percentage and the time limit within which payment must be made.
The invoice itself contains three mandatory elements per VAT rate to correctly process discount cash:
Allowance → the discount percentage or amount
Charge → the calculated discount amount
Tax segment → determines how VAT is applied to the rebate
On this basis, a receiving party can determine:
Whether there is entitlement to the early payment discount
what amount the discount represents
Important to know:
Peppol ensures correct and structured invoice delivery. However, the application of cash discount is done at the receiving end, not automatically by Peppol itself. Therefore, it is important to work with an AP tool, ERP system or Access Point that has experience with cash discount and can interpret it correctly.

Why setting cash discount correctly is crucial
An improperly set cash discount can affect different teams within your organization.
For finance teams:
Invoices may be unclear or contain incorrect amounts
Additional manual work to correct errors
Erroneous VAT calculations and tax reports
Delays in payments due to customer confusion
For IT teams:
Additional support requests from finance or customers
Disrupted workflows or automatic processing of invoices
Difficulties in integrations with ERP systems or e-invoicing tools
Complexity in modifying systems to correct errors

Early payment discount is technically possible in Peppol. This is done via allowances, charges & tax segments in the UBL, so that the invoice remains correct. In practice, this requires proper implementation and alignment with your systems. Concrete XML examples are part of our project support for customers.

No. The rebate can be fully included in the UBL via allowances, charge & tax segment. VAT is calculated on the total amount including the rebate, regardless of whether the customer actually takes the rebate. A credit note is not required for this purpose.
