 In most countries, you will be required to pay some form of sales tax for your event tickets. If you don't know about
 the exact rules, you should consult a professional tax consultant right now.

+FAQ and Troubleshooting
+=======================
+
+How can I test my shop before taking it live?
+---------------------------------------------
+
+There are multiple ways to do this.
+
+First, you could just create some orders in your real shop and cancel/refund them later. If you don't want to process
+real payments for the tests, you can either use a "manual" payment method like bank transfer and just mark the orders
+as paid with the button in the backend, or if you want to use e.g. Stripe, you can configure pretix to use your keys
+for the Stripe test sytem and use their test credit cars. Read our :ref:`Stripe documentation <stripe>` for more
+information.
+
+Second, you could create a separate event, just for testing. In the last step of the :ref:`event creation process <event_create>`,
+you can specify that you want to copy all settings from your real event, so you don't have to do all of it twice.
+
+We are planning to add a dedicated test mode in a later version of pretix.
+
+If you are using the hosted service at pretix.eu and want to get rid of the test orders completely, contact us at
+support@pretix.eu and we can remove them for you. Please note that we only are able to do that *before* you have
+received any real orders (i.e. taken the shop public). We won't charge any fees for test orders or test events.
+
+How do I delete an event?
+-------------------------
+
+It is currently not possible to delete events, you can just disable the shop by clicking the first square on your event
+dashboard. Events can't be deleted as they most likely contain information on financial transactions which legally
+needs to be kept on record for multiple years in most countries.
+
+If you are using the hosted service at pretix.eu and want to get rid of an event that you only used for testing, contact
+us at support@pretix.eu and we can remove it for you.
+
+Why doesn't my product show up in the ticket shop?
+--------------------------------------------------
+
+If you created a product and it doesn't show up, please follow the following steps to find out why:
+
+1. Check if the product's "active" checkbox is enabled.
+2. Check if the product is in a category that has the "Products in this category are add-on products" checkbox enabled.
+   If this is the case, the product won't show up on the shop front page, but only in the first step of checkout when
+   a product in the cart allows to add add-on products from this category.
+3. Check if the product's "Available from" or "Available until" settings restrict it to a date range.
+4. Check if the product's checkbox "This product will only be shown if a voucher matching the product is redeemed." is
+   enabled. If this is the case, the product will only be shown if the customer redeems a voucher that *directly* matches
+   to this product. It will not be shown if the voucher only is configured to match a quota that contains the product.
+5. Check that a quota exists that contains this product. If your product has variations, check that at least one
+   variation is contained in a quota. If your event is an event series, make sure that the product is contained in a
+   quota that is assigned to the series date that you access the shop for.
+6. If the sale period has not started yet or is already over, check the "Show items outside presale period" setting of
+   your event.

+Using a custom domain
+=====================
+
+By default, event shops built with pretix are accessible at ``https://<domain>/<organizer>/<event>/``, where
+``<domain>`` is ``pretix.eu`` if you are using our hosted service and ``<organizer>`` and ``<event>`` are the short
+form versions of your organizer account name and event name, respectively.
+
+However, you are also able to use a custom domain for your ticket shops! If you work for "Awesome Party Corporation"
+and your website is ``awesomepartycorp.com``, you might want to sell your tickets at ``tickets.awesomepartycorp.com``
+and with pretix, you can do this. On this page, you find out the necessary steps to take.
+
+With the pretix.eu hosted service
+---------------------------------
+
+Step 1: DNS Configuration
+#########################
+
+Go to the website of the provider you registered your domain name with. Look for the "DNS" settings page in their
+interface. Unfortunately, we can't tell you exactly how that is named and how it looks, since it is different for every
+domain provider.
+
+Use this interface to add a new subdomain record, e.g. ``tickets`` of the type ``CNAME`` (might also be called "alias").
+The value of the record should be ``www.pretix.eu``.
+
+Step 2: Wait for the DNS entry to propagate
+###########################################
+
+Submit your changes and wait a bit, it can regularly take up to three hours for DNS changes to propagate to the caches
+of all DNS servers. You can try checking by accessing your new subdomain, ``http://tickets.awesomepartycorp.com``.
+If DNS was changed successfully, you should see a SSL certificate error. If you ignore the error and access the page
+anyways, you should get a pretix-themed error page with the headline "Unknown domain".
+
+Step 3: Tell us
+###############
+
+Write an email to support@pretix.eu, naming your new domain and your organizer account. We will then generate a SSL
+certificate for you (for free!) and configure the domain.
+
+
+With a custom pretix installation
+---------------------------------
+
+If you installed pretix on a server yourself, you can also use separate domains for separate organizers.
+First of all, configure your webserver or reverse proxy to pass requests to the new domain to pretix as well.
+Then, go to the organizer account in pretix and click the "Edit" button. Enter the new domain in the "Custom Domain"
+field, then you're done!
