This article explains how to add fees to an installment plan or subscription from a Learnybox offer and how to define the VAT rule applied to those fees.
You can choose to:
apply no VAT to the fees
use the offer’s default VAT rate
Step 1 – Access the payment methods for your offer
Go to Sales → Offers
Click the offer you wish to configure to access its dashboard.
Open the Payment Methods tab
Click Add payment method to add a new payment method, or click the Edit icon for the payment method you want to modify.
Step 2 – Open the payment configuration
Expand the Payment configuration section.
Locate the Increase setting. It will allow you to add fees to the total order amount when a customer selects that payment method.
⚠️ It is available only when the payment type is set to:
Step 3 – Enter the increase amount
In the Increase field, enter the additional amount you want to charge. This amount represents your fees (or surcharge).
The way this amount is applied depends on the payment type.
a) For multiple payments
The amount entered is added to the total price and divided across the configured number of payments.
For example, when you add a €10 increase to a four-payment installment plan, the customer is charged an additional €2.50 with each payment.
b) For a subscription
The amount entered is added to every recurring payment for as long as the subscription remains active.
For example, when you add a €10 increase to a monthly subscription, the customer is charged an additional €10 each month.
Step 4 – Choose the VAT rule applied to the increase
Use the VAT selector to the right of the increase amount to choose how VAT should apply.
The available options are:
Standard VAT — the offer’s default rate: Applies the VAT rate configured by default for the offer.
No VAT: Does not apply VAT to the fees.
⚠️ The VAT calculation and the final amount displayed to the customer are shown directly at checkout.
What your customer will see
When placing their order, the customer will see:
the order amount
the increase applied according to the payment type
the VAT applied to that increase
the final amount they will be charged
These details are automatically included on the order form and on invoices generated after the setting has been enabled.
How to check that the configuration works
After saving your configuration:
Open the offer’s direct order link.
Select the relevant payment method.
Check:
the fee amount
the VAT applied
the final total displayed to the customer
