+# Account management
+You can manage billing for your Timescale Cloud account by navigating to the
+`Billing` details section in your Cloud console. From here, you can see your
+monthly usage, past payments you have made, the estimated cost of your next
+payment confirmation, and your current payment method.
+
+## About Timescale Cloud billing
+Timescale Cloud payment confirmations are issued on the first day of every
+month, and cover usage of your Timescale Cloud services for the entire calendar
+month. By default, your payment confirmation is sent to the email address you
+registered your account with. If you want to set a different billing email
+address, you can do so on the `Billing` details page, see instructions in this
+section.
+
+The billing email you receive at the end of each calendar month includes a PDF
+copy of your payment confirmation for your own records. The PDF includes
+information on the services you have used through the month, broken down into
+storage, compute, and VPC hourly consumption.
+
+You can see previously issued payment confirmations on the `Billing` details
+page, in the `Past Payments` section. If a payment could not be processed,
+payment confirmations in this section display an error asking you to review the
+payment method.
+
+When you open a new Timescale Cloud account, the first thirty days is free for
+you to use. During the trial, a payment confirmation is issued on the last day
+of the calendar month for the value of the services you have used, with a
+discount applied to bring the payment confirmation total to $0.00. If the
+entirety of your consumption for the month was within the trial, you do not
+receive an emailed payment confirmation, but the payment confirmation is
+available to download in the `Past Payments` section.
+
+## Add or change payment methods
+If you haven't yet added a payment method, you can add one in this section. You
+can also update to a new credit card here.
+
+<procedure>
+
+### Adding or changing a payment method
+1.  [Log in to your Timescale Cloud account][cloud-login] and navigate to
+    the `Billing` details section.
+1.  Click `Add a payment method`. If you already have a payment method saved,
+    you need to delete it before you start. Click the trash can icon to delete
+    your saved credit card.
+1.  Type your credit card details, and click `Add billing address`.
+1.  Type your address, and click `Save payment method`.

+
+<highlight type="note">
+The first charge on your new credit card is for the period from the date you
+added the card, to the end of that calendar month. After that, all payment
+confirmations are for usage from the first of the month, to the last day of the
+month.
+</highlight>
+
+</procedure>
+
+## Add or change your billing email address
+By default, your Timescale Cloud payment confirmations are sent to the email
+address that you used when you signed up. This is also the address that receives
+alerts about your Timescale Cloud services. If you want your payment
+confirmations to also go to a different email address, for example the email address
+for your finance department, you can add it in the `Billing` details section.
+
+<highlight type="note">
+When you add a billing email address, payment confirmations are sent to both the
+email address you add, and the original email address that you signed up with.
+</highlight>
+
+<procedure>
+
+### Adding a billing email address
+1.  [Log in to your Timescale Cloud account][cloud-login] and navigate to
+    the `Billing` details section.
+1.  In the `Payment emails` tab, click `Add New Email`.
+1.  Type the email address that you want Timescale Cloud payment confirmations
+    sent to, and click `Add email`. A confirmation email is sent to the email
+    address you entered.
+1.  Follow the instructions in the confirmation email to confirm the email
+    address. Another email is sent to the address you signed up with to notify
+    that the new email address is saved.
