Release 4.10.0 of pretix

May 27, 2022

Today, we are releasing pretix 4.10.0. This release contains a feature we are really excited about: automated discounts based on cart content! Of course, there are lots of bug fixes and improvements on smaller features throughout the system as well.

Big thanks go to Edd28, Emanuele Signoretta, Henryk Plötz, Helias Mackay, Iryna Loik, Iryna N, Jonathan Berger, Maico Timmerman, Ola, Olha Dolinska, Viktoriia, Yuliya Palmova, and Олександра Сергіївна Миргородська who contributed to this release. ❤️

pretix 4.10.0 is now available for installation via pip. The new Docker images will appear on Docker over the next few hours. All customers of pretix Hosted are already using the new version and do not need to take any action.

Automated discounts

This release introduces a new feature into our range of pricing options: Automated discounts. With this powerful new part of pretix, you can create rules that automatically grant a discount when a cart fulfills a certain condition. Typical examples include:

  • a group discount that automatically grants 20 % off if someone buys at least 5 tickets.

  • a 3-for-2 discount that reduces the price of one ticket to zero if at least three are in the cart.

  • a volume discount that automatically grants 10 % off if someone spends at least €500.

  • a loyality discount that automatically grants 10 % off if someone buys tickets to at least 3 different dates of the same event series.

All of these can of course be limited to specific products, sales channels, or time frames. And in contrast to vouchers, your customers do not need to do a single thing to profit from the discount, as soon as they add the products to the cart, the discount will automatically be applied.

You can find the new options in the main menu at "Products" > "Discounts".

Change to voucher budgets

(If you use pretix Hosted and have NOT received an email from us about this earlier this month, you can very likely ignore this section.)

As a side effect of the new discount feature, our pricing logic has changed with an impact on the "maximum budget" feature for vouchers. Currently, if a voucher with a fixed budget is redeemed, the amount subtracted from the budget is calculated by subtracting the actual gross price of the item from the gross price it would have had without the voucher. This has a few disadvantages, such as when dealing with country-specific tax rates, or with other factors affecting the price such as a customer-determined price.

For all vouchers redeemed after the upgrade to 4.10, voucher budgets will be handled differently and only respect the discount given directly by the voucher. Additionally, if the product's tax rule is set to not include taxes in the configured price, only the net difference will be subtracted from the budget.

Voucher redemptions created before that date will be unaffected.

  • Example 1: If you have a product that costs €119.00 incl. 19% VAT for some countries and €100.00 incl. 0% VAT for other countries, a voucher that reduces the price by 10% will now always use €11.90 of the budget, instead of sometimes €11.90 and sometimes €10.00 like before.

  • Example 2: If you have a product that costs €100 and that allows customers to voluntarily increase the price, a voucher that reduces the price by 50% will now always use €50 of the budget, instad of sometimes €50 and sometimes less, depending on the customer's input.

  • Example 3: If you have a product configured with a price of €100.00 plus 19% VAT, a voucher that reduced the price by 10% will now only use €10.00 of the budget instead of €11.90.

We believe that new method is both clearer to understand and closer to what most of you are trying to achieve with voucher budgets.

Warning: Upcoming changes to the PayPal plugin

In anticipation of some big changes to the PayPal plugin coming with the next pretix release, we will be deprecating event-level PayPal webhooks. If you are using PayPal, please read the following section to see if this change affects you. If you have been using the "Connect with PayPal" feature, you can skip this section.

If you have manually set up a webhook in the PayPal Developer Center pointing to a event-level URL (such as, you will need to change your webhook to point to the global PayPal webhook URL which is posted on the PayPal settings page of your event. The new webhook-URL can be identified easily, as it ends in /_paypal/webhook/.

We do not expect many to be impacted by this since we have been recommending the global URL for over 4 years now.

In addition, there are also big changes coming to the simplified "Connect with PayPal"-flow for users of pretix Community and Enterprise. With the upcoming pretix release, you will need to use specially crafted platform-level API-keys in order to offer this feature to your users. If you are using platform-level API-keys for PayPal on your self-hosted pretix system, please reach out to your PayPal Account Manager to be onboarded for ISU.
