20% off everything – with no unexpected discount costs.
Limit discount risks
With every addition to your range, every new business customer and every additional sales channel, the risk of unplanned discount costs on percentage campaigns grows. A single large order with a public 20% code can exceed the planned campaign budget per redemption several times over.
What this OPAL does for you
1.Percentage vouchers stay percentage-based on the outside, while internally they are capped at a fixed maximum amount per series.
2.The setting is made directly in the familiar voucher series management; multi-currency conversion and the checkout note are built in.
3.This OPAL comes directly from the platform vendor and works without core overrides or external dependencies.
Before / After
A 20% code is applied to a €1,500 cart and takes €300 out of your margin that nobody had planned for.
The same code on the same cart deducts no more than €30, exactly as planned.
The finance team cuts your campaign from '20% off everything' to '5% off everything' because nobody can control the outliers.
The briefing stays at '20% off everything' because the maximum cost per redemption is fixed.
A customer applies the 20% voucher to an €800 order, sees only €30 deducted and calls customer service.
She sees 'Max. discount: €30.00' right next to the voucher and understands immediately.

Maximum amount per voucher series
You set a maximum discount amount per voucher series. The voucher stays percentage-based but is automatically capped as soon as the calculated discount reaches your limit.
Automatic multi-currency conversion
You store the maximum amount once in the default currency. For orders in other currencies, this OPAL converts it automatically based on the stored exchange rate.
Set directly in the voucher series
The two new fields appear in the familiar voucher series form in the admin area.
Optional checkout note
Can be enabled via a checkbox: a note about the maximum amount appears right next to the voucher line in the checkout. It works in any theme where the corresponding Twig block is included, even with JavaScript disabled.
Automatic input correction
Negative values entered by mistake are automatically normalized to 0 on saving, without an error message or interruption to the workflow.
Bilingual DE and EN
All admin fields, help texts and the checkout note are available in German and English right after installation. Ready to use for DACH and international stores.
Who is this OPAL for?
Marketing / editorial
You are preparing a campaign briefing and need to justify the discount percentage to the finance team.
How it helps
You can push through bolder percentage promotions because the budget behind them is defensible. The messaging stays '20%', not '5%'. The optional checkout note makes your campaign transparent and professional for customers, so they understand the discount instead of complaining to you.
