Moves and generalizes `switch_realm_from_standard_to_plus_plan`
in stripe.py to be a more general function for changing a
CustomerPlan to a new and valid tier, `do_change_plan_to_new_tier`.
Adds a helper function with the previous function name to be used
for the support view and management command for changing a realm
from the Standard plan tier to the Plus plan tier.
Renames CustomerPlan.SWITCH_NOW_FROM_STANDARD_TO_PLUS to be more
generic, CustomerPlan.SWITCH_PLAN_TIER_NOW.
Because the plan tier change is immediate, moves the code to end
the current plan with the old tier and create the new plan with
the new tier from `make_end_of_cycle_updates_if_needed` to instead
be in a separate helper function, `switch_plan_tier`.
This commit moves a major portion of the 'update_plan`
view to a new shared 'BillingSession.do_update_plan' method.
This refactoring will help in minimizing duplicate code
while supporting both realm and remote_server customers.
This commit updates the 'get_initial_upgrade_context' method
to use 'get_price_per_license' for determining 'annual_price'
and 'monthly_price' based on tier and discount instead of hardcoding.
Also, removed the 'percent_off' page_params as
'get_price_per_license' already performs the price calculation
taking discount into consideration.
If the update / add card session is successful, return user to
manual license management page if user was on it before clicking
the add / update card button.
This commit moves a major portion of the 'initial_upgrade`
view to a new shared 'BillingSession.do_initial_upgrade' method.
This refactoring will help in minimizing duplicate code
while supporting both realm and remote_server customers.
These new models are incomplete and totally untested, but merging this
will provide valuable scaffolding for doing smaller PRs working on
individual gaps, and reveals a clear set of TODOs/refactoring/model
changes needed to support where want to end up.

This commit moves the main context creation part of the
'billing_home` view to a new shared
'BillingSession.get_billing_page_context' method.
This refactoring will help in minimizing duplicate code
while supporting both realm and remote_server customers.
Moves the 'make_end_of_cycle_updates_if_needed' function to
the 'BillingSession' abstract class.
This refactoring will help in minimizing duplicate code while
supporting both realm and remote_server customers.
Since the function is called from our main daily billing cron job
as well, we have changed 'RealmBillingSession' to accept 'user=None'
(our convention for automated system jobs).
There is a discrepancy between price per license shown on billing
and upgrade page for annual billing frequency due to difference
in methods used to calculate the amount.
To fix it, we use the same method on both the pages.
I didn't use the helpers.format_money directly here since that would
create a visual delay in showing the price per license which will
not be nice considering that will be the only thing on this page
being updated that way.
The stripe fixture used is same as
free_trial_upgrade_by_card--Customer.retrieve.3.json
This commit moves a major portion of the 'upgrade`
view to a new shared 'BillingSession.do_upgrade' method.
This refactoring will help in minimizing duplicate code
while supporting both realm and remote_server customers.
Moves the 'process_initial_upgrade' function to the
'BillingSession' abstract class.
This refactoring will help in minimizing duplicate code while
supporting both realm and remote_server customers.
Updates `process_initial_upgrade` to take a plan_tier parameter,
so that information can be specific to the type of BillingSession.
Note that ideally the plan tier would be passed as metadata to the
stripe.checkout.Session, but in order to do so, we need to be able
to update the generated stripe fixtures for tests. So for now, we
set the plan tier directly in the stripe event handler code.
Instead of hard coding the string for the stripe.InvoiceItem and
stripe.Invoice statement_descriptor, we use the name of the plan
that was just created.
Creates `do_change_plan_type` as a BillingSession abstract method
as an alias for updating the plan_type for a realm (and eventually
remote server).
This removes the last direct reference to a customer's realm in
`process_initial_upgrade`.
Creates `current_count_for_billed_licenses` as an abstract method
in BillingSession class, to get the latest seat count for the realm
(and eventually remote server) connected to the customer.
Moves the 'setup_upgrade_checkout_session_and_payment_intent'
function to the 'BillingSession' abstract class.
This refactoring will help in minimizing duplicate code while
supporting both realm and remote_server customers.
Instead of using the data from the stripe.SetupIntent for processing
an initial upgrade for the free trial session types, use the metadata
from the stripe.checkout.Session that was returned.
The metadata is the same for both the checkout session and the setup
intent.
According to stripe's documentation for attaching payment methods to
customers (see https://stripe.com/docs/api/payment_methods/attach),
payment methods should be attached to customers through a SetupIntent
or PaymentIntent, which is what we do as we process new customers
and accounts.
Updates create_stripe_customer so that it is clear that the payment
method should not be added when we directly create a new stripe
customer.
There is a 22 char limit on the stripe.Invoice.statement_descriptor
field. The current value for that field in this error case, "Zulip
Cloud Standard Credit" is 27 chars.
Updates the value for this error case to be "Cloud Standard Credit".
Adds `create_stripe_payment_intent` to the BillingSession abstract
class for the initial upgrade process, which is used only in
`setup_upgrade_checkout_session_and_payment_intent`.
Adds a helper dataclass for the data used to create the stripe
payment intent, StripePaymentIntentData, for the implementation of
more than one child class of BillingSession.
Also adds two abstract helper functions for getting the above stripe
payment intent data as well as updating that data for a stripe
checkout session that is associated with a payment intent:
update_data_for_checkout_session_and_payment_intent,
get_data_for_stripe_payment_intent.
Adds `create_stripe_checkout_session` to BillingSession abstract
class, which is then used in all places where a stripe.checkout.Session
and Session were created: start_retry_payment_intent_session,
start_card_update_stripe_session, and
setup_upgrade_checkout_session_and_payment_intent.
Adds a `billing_session_url` abstract property to the BillingSession
abstract class and for the RealmBillingSession child class sets that
value to `self.realm.uri`.
Moves `update_billing_method_of_current_plan` to the BillingSession
abstract class.
Adds a helper function for support views for the realm case:
`update_realm_billing_method`.
Moves `update_sponsorship_status` to BillingSession abstract class
as `update_customer_sponsorship_status`.
Updates the support views to have a helper for updating this on a
realm: `update_realm_sponsorship_status`.
Makes `approve_sponshorship` an abstract method in BillingSession
abstract base class and moves the implementation for realms to the
RealmBillingSession child class.
Adds `approve_realm_sponsorship` helper function that's used in
the support view and initiates the billing session.
