+Resource description
+--------------------
+
+Discounts provide a way to automatically reduce the price of a cart if it matches a given set of conditions.
+Discounts are available to everyone. If you want to give a discount just to specific persons, look at
+:ref:`vouchers <rest-vouchers>` instead. If you are interested in the behind-the-scenes details of how
+discounts are calculated for a specific order, have a look at :ref:`our algorithm documentation <algorithms-pricing>`.

+Pricing algorithms
+==================
+
+With pretix being an e-commerce application, one of its core tasks is to determine the price of a purchase. With the
+complexity allowed by our range of features, this is not a trivial task and there are many edge cases that need to be
+clearly defined. The most challenging part about this is that there are many situations in which a price might change
+while the user is going through the checkout process and we're learning more information about them or their purchase.
+For example, prices change when
+
+* The cart expires and the listed prices changed in the meantime
+* The user adds an invoice address that triggers a change in taxation
+* The user chooses a custom price for an add-on product and adjusts the price later on
+* The user adds a voucher to their cart
+* An automatic discount is applied
+
+For the purposes of this page, we're making a distinction between "naive prices" (which are just a plain number like 23.00), and
+"taxed prices" (which are a combination of a net price, a tax rate, and a gross price, like 19.33 + 19% = 23.00).
+
+Computation of listed prices
+----------------------------
+
+When showing a list of products, e.g. on the event front page, we always need to show a price. This price is what we
+call the "listed price" later on.
+
+To compute the listed price, we first use the ``default_price`` attribute of the ``Item`` that is being shown.
+If we are showing an ``ItemVariation`` and that variation has a ``default_price`` set on itself, the variation's price
+takes precedence and replaces the item's price.
+If we're in an event series and there exists a ``SubEventItem`` or ``SubEventItemVariation`` with a price set, the
+subevent's price configuration takes precedence over both the item as well as the variation and replaces the listed price.
+
+Listed prices are naive prices. Before we actually show them to the user, we need to check if ``TaxRule.price_includes_tax``
+is set to determine if we need to add tax or subtract tax to get to the taxed price. We then consider the event's
+``display_net_prices`` setting to figure out which way to present the taxed price in the interface.
+
+Guarantees on listed prices
+---------------------------
+
+One goal of all further logic is that if a user sees a listed price, they are guaranteed to get the product at that
+price as long as they complete their purchase within the cart expiration time frame. For example, if the cart expiration
+time is set to 30 minutes and someone puts a item listed at €23 in their cart at 4pm, they can still complete checkout
+at €23 until 4.30pm, even if the organizer decides to raise the price to €25 at 4.10pm. If they complete checkout after
+4.30pm, their cart will be adjusted to the new price and the user will see a warning that the price has changed.
+
+Computation of cart prices
+--------------------------
+
+Input
+"""""
+
+To ensure the guarantee mentioned above, even in the light of all possible dynamic changes, the ``listed_price``
+is explicitly stored in the ``CartPosition`` model after the item has been added to the cart.
+
+If ``Item.free_price`` is set, the user is allowed to voluntarily increase the price. In this case, the user's input
+is stored as ``custom_price_input`` without much further validation for use further down below in the process.
+If ``display_net_prices`` is set, the user's input is also considered to be a net price and ``custom_price_input_is_net``
+is stored for the cart position. In any other case, the user's input is considered to be a gross price based on the tax
+rules' default tax rate.
+
+The computation of prices in the cart always starts from the ``listed_price``. The ``list_price`` is only computed
+when adding the product to the cart or when extending the cart's lifetime after it expired. All other steps such as
+creating an order based on the cart trust ``list_price`` without further checks.
+
+Vouchers
+""""""""
+
+As a first step, the cart is checked for any voucher that should be applied to the position. If such a voucher exists,
+it's discount (percentage or fixed) is applied to the listed price. The result of this is stored to ``price_after_voucher``.
+Since ``listed_price`` naive, ``price_after_voucher`` is naive as well. As a consequence, if you have a voucher configured
+to "set the price to €10", it depends on ``TaxRule.price_includes_tax`` again whether this is €10 including or excluding
+taxes.
+
+The ``price_after_voucher`` is only computed when adding the product to the cart or when extending the cart's
+lifetime after it expired. It is also checked again when the order is created, since the available discount might have
+changed due to the voucher's budget being (almost) exhausted.
+
+Line price
+""""""""""
+
+The next step computes the final price of this position if it is the only position in the cart. This happens in "reverse
+order", i.e. before the computation can be performed for a cart position, the step needs to be performed on all of its
+bundled positions. The sum of ``price_after_voucher`` of all bundled positions is now called ``bundled_sum``.
+
+First, the value from ``price_after_voucher`` will be processed by the applicable ``TaxRule.tax()`` (which is complex
+in itself but is not documented here in detail at the moment).
+
+If ``custom_price_input`` is not set, ``bundled_sum`` will be subtracted from the gross price and the net price is
+adjusted accordingly. The result is stored as ``tax_rate`` and ``line_price_gross`` in the cart position.
+
+If ``custom_price_input`` is set, the value will be compared to either the gross or the net value of the ``tax()``
+result, depending on ``custom_price_input_is_net``. If the comparison yields that the custom price is higher, ``tax()``
+will be called again . Then, ``bundled_sum`` will be subtracted from the gross price and the result is stored like
+above.
+
+The computation of ``line_price_gross`` from ``price_after_voucher``, ``custom_price_input``, and tax settings
+is repeated after every change of anything in the cart or after every change of the invoice address.
+
+Discounts
+---------
+
+After ``line_price_gross`` has been computed for all positions, the discount engine will run to apply any automatic
+discounts. Organizers can add rules for automatic discounts in the pretix backend. These rules are ordered and
+will be applied in order. Every cart position can only be "used" by one discount rule. "Used" can either mean that
+the price of the position was actually discounted, but it can also mean that the position was required to enable
+a discount for a different position, e.g. in case of a "buy 3 for the price of 2" offer.
+
+The algorithm for applying an individual discount rule first starts with eliminating all products that do not match
+the rule based on its product scope. Then, the algorithm is handled differently for different configurations.
+
+Case 1: Discount based on minimum value without respect to subevents
+""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""
+
+* Check whether the gross sum of all positions is at least ``condition_min_value``, otherwise abort.
+
+* Reduce the price of all positions by ``benefit_discount_matching_percent``.
+
+* Mark all positions as "used" to hide them from further rules
+
+Case 2: Discount based on minimum number of tickets without respect to subevents
+""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""
+
+* Check whether the number of all positions is at least ``condition_min_count``, otherwise abort.
+
+* If ``benefit_only_apply_to_cheapest_n_maches`` is set,
+
+    * Sort all positions by price.
+    * Reduce the price of the first ``n_positions // condition_min_count * benefit_only_apply_to_cheapest_n_matches`` positions by ``benefit_discount_matching_percent``.
+    * Mark the first ``n_positions // condition_min_count * condition_min_count`` as "used" to hide them from further rules.
+    * Mark all positions as "used" to hide them from further rules.
+
+* Else,
+
+    * Reduce the price of all positions by ``benefit_discount_matching_percent``.
+    * Mark all positions as "used" to hide them from further rules.
+
+Case 3: Discount only for products of the same subevent
+"""""""""""""""""""""""""""""""""""""""""""""""""""""""
+
+* Split the cart into groups based on the subevent.
+
+* Proceed with case 1 or 2 for every group.
+
+Case 4: Discount only for products of distinct subevents
+""""""""""""""""""""""""""""""""""""""""""""""""""""""""
+
+* Let ``subevents`` be a list of distinct subevents in the cart.
+
+* Let ``positions[subevent]`` be a list of positions for every subevent.
+
+* Let ``current_group`` be the current group and ``groups`` the list of all groups.
+
+* Repeat
+
+    * Order ``subevents`` by the length of their ``positions[subevent]`` list, starting with the longest list.
+      Do not count positions that are part of ``current_group`` already.
+
+    * Let ``candidates`` be the concatenation of all ``positions[subevent]`` lists with the same length as the
+      longest list.
+
+    * If ``candidates`` is empty, abort the repetition.
+
+    * Order ``candidates`` by their price, starting with the lowest price.
+
+    * Pick one entry from ``candidates`` and put it into ``current_group``. If ``current_group`` is shorter than
+      ``benefit_only_apply_to_cheapest_n_matches``, we pick from the start (lowest price), otherwise we pick from
+      the end (highest price)
+
+    * If ``current_group`` is now ``condition_min_count``, remove all entries from ``current_group`` from
+      ``positions[…]``, add ``current_group`` to ``groups``, and reset ``current_group`` to an empty group.
+
+* For every position still left in a ``positions[…]`` list, try if there is any ``group`` in groups that it can
+  still be added to without violating the rule of distinct subevents
+
+* For every group in ``groups``, proceed with case 1 or 2.

 Use case: Group discounts
 -------------------------
 
-Often times, you want to give discounts for whole groups attending your event. pretix can't automatically discount based on volume, but there's still some ways you can set up group tickets.
+Often times, you want to give discounts for whole groups attending your event.
 
-Flexible group sizes
+Automatic discounts
+"""""""""""""""""""
+
+pretix can automatically grant discounts if a certain condition is met, such as a specific group size. To set this up,
+head to **Products**, **Discounts** in the event navigation and **Create a new discount**. You can choose a name so you
+can later find this again. You can also optionally restrict the discount to a specific time frame or a specific sales
+channel.
+
+Next, either select **Apply to all products** or create a selection of products that are eligible for the discount.
+
+For a **percentual group discount** similar to "if you buy at least 5 tickets, you get 20 percent off", set
+**Minimum number of matching products** to "5" and **Percentual discount on matching products** to "20.00".
+
+For a **buy-X-get-Y discount**, e.g. "if you buy 5 tickets, you get one free", set
+**Minimum number of matching products** to "5", **Percentual discount on matching products** to "100.00", and
+**Apply discount only to this number of matching products** to "1".
+
+Fixed group packages
 """"""""""""""""""""
 
-If you want to give out discounted tickets to groups starting at a given size, but still billed per person, you can do so by creating a special **Group ticket** at the per-person price and set the **Minimum amount per order** option of the ticket to the minimal group size.
+If you want to sell group tickets in fixed sizes, e.g. a table of eight at your gala dinner, you can use product bundles.
+Assuming you already set up a ticket for admission of single persons, you then set up a second product **Table (8 persons)**
+with a discounted full price. Then, head to the **Bundled products** tab of that product and add one bundle configuration
+to include the single admission product **eight times**. Next, create an unlimited quota mapped to the new product.
+
+This way, the purchase of a table will automatically create eight tickets, leading to a correct calculation of your total
+quota and, as expected, eight persons on your check-in list. You can even ask for the individual names of the persons
+during checkout.
+
+Minimum order amount
+""""""""""""""""""""
+
+If you want to promote discounted group tickets in your price list, you can also do so by creating a special
+**Group ticket** at the reduced per-person price and set the **Minimum amount per order** option of the ticket to the minimal
+group size.
 
 For more complex use cases, you can also use add-on products that can be chosen multiple times.
 
 This way, your ticket can be bought an arbitrary number of times – but no less than the given minimal amount per order.
