The subscription item object

A subscription item is one price on a subscription: a price, a quantity and a unit amount, billed every interval. Its plan is its price’s. A subscription’s amounts are summed from its items. Items are usually written with their subscription, as its items, and can also be changed one at a time.

Attributes

idstring (UUID)
The item’s Summerbase id. Anywhere an item is addressed, one of its identities works too.
objectstring
The object’s type, always subscription_item.

Always subscription_item
created_attimestamp
When this item was first recorded.
deletedboolean
Whether the item has come off the subscription. When it did is the effective_at of the write that set this.
discount_amountdecimal string
What comes off this item’s invoice, in the subscription’s currency, after every discount the source applies to it has been worked out: coupons at any level, stacked in the source’s order, restricted to the products they cover. The item is worth unit_amount × quantity less this, each interval. Zero is no discount.
discount_ends_attimestamp
When the discount, or the earliest part of it, stops applying, if the source knows. Information for a reader: the discount comes off when the source writes a smaller discount_amount, not when this passes.
identitiesarray of strings
What each source calls this subscription item, as source:id. Any entry addresses it — stripe:cus_123.
intervalenum
The unit this item bills in.

One of day, week, month, year
interval_countinteger
How many intervals between charges.
net_amountdecimal string
What this item comes to each time it is billed, in its subscription’s currency: unit_amount times quantity, less discount_amount.
plan_idstring (UUID)
The plan this item is on: its price’s.
plan_namestring
What the plan this item is on is called: its price’s.
priceobject
The price this item is on, when a source named one. Expandable.

    The provider’s own id for the account the source is connected to: acct_… for Stripe. Kept through a disconnect, so that connecting again is checked against it.

  - slugstring
    How this source’s records are identified — the stripe in stripe:cus_123. Lowercase letters, digits, hyphens and underscores; unique within the project and fixed once the source exists, because integrations hard-code it. A reference shaped like an id is read as one, so a slug may not look like a UUID.
  - webhook_installed_attimestamp
    When the provider’s webhook was installed for this source — by the connection, or by hand and registered with register_stripe_webhook — or empty: nothing is connected, or the source is connected without a webhook and its changes arrive with the hourly reconcile.
  - webhook_urlstring
    Where the provider posts this source’s events: the address of the endpoint a connection installs, and of one to install by hand. Empty for a source whose provider posts no webhooks.

properties_by_sourceobject
Every source’s properties on this subscription item, keyed by source slug — including your own. Read-only: a write only ever reaches the source it is attributed to.
quantitydecimal string
How many units at this unit amount. A decimal, because a unit is not always a whole seat: a billing system that meters usage sends 1.5 of something, and rounding it would misstate what the item is worth.
subscriptionobject
The subscription this is an item of. Expandable.

  Always subscription
- annual_amountdecimal string
  What this subscription is worth a year, in currency_code: monthly_amount times twelve.
- billing_amountsarray of objects
  What this subscription comes to each time it bills: the items still on it, their net_amount summed per billing interval, longest interval first. One entry for nearly every subscription; one per interval for a subscription whose items bill on different ones, such as a yearly fee beside a monthly one. Its price whatever its status — a trial still has one. monthly_amount is what it is worth on one footing.

  - intervalenum
    The unit these items bill in: day, week, month or year.
    
    One of day, week, month, year

- currency_codestring
  The currency it bills in, by its ISO 4217 code.
- current_period_ends_attimestamp
  When the current billing period ends. The next charge is due then, unless a cancellation is booked for it.

    The customer’s Summerbase id. Anywhere a customer is addressed, one of its identities works too.
  - objectstring

    Always customer
  - arrdecimal string
    What this customer is worth a year, in the project’s reporting currency, at today’s rate: mrr, rounded to the cent, times twelve.
  - churned_attimestamp
    When the current churn began — the instant status became churned. Null while the customer is trialing or active, and cleared when they come back.
  - countryobject
    The country the customer is billed in. Expandable.
  - country_codestring
    The country the customer is billed in, by its ISO 3166-1 alpha-2 code — the country_code property, resolved the same way as name, from the highest-priority source whose value is a country’s code. Expand country for its name.
  - created_attimestamp
    When Summerbase first recorded the customer.
  - emailstring
    The customer’s address, resolved the same way as name.
  - erasuresarray of objects
    Every erasure of their personal data, oldest first. Expandable.
  - first_paying_attimestamp
    The first instant this customer had revenue — when status first became paying, and what cohort analysis groups by. Set once and kept through churn and reactivation. Which month it falls in depends on the timezone being reported in.
  - first_seen_attimestamp
    The earliest instant anything was asserted about this customer, their subscriptions or their items — the first thing we were told. Set once.
  - first_subscribed_attimestamp
    The first instant one of this customer’s subscriptions was live, free or paying — when status first became one of the two. Set once and kept through churn.
  - identitiesarray of strings
    What each source calls this customer, as source:id. Any entry addresses it — stripe:cus_123.
  - mrrdecimal string
    What this customer is worth a month, in the project’s reporting currency, at today’s rate, rounded to the cent.
    
    Every kind of revenue counts, each change converted from the currency it was billed in, so this amount moves when a rate does and when the project’s reporting currency changes. The same amount a filter on customer.mrr compares and a list sorted by mrr orders by.
  - namestring
    What the customer is called — the name property, resolved to the highest-priority source that has one. Write properties.name to change it.
  - propertiesobject
    Your source’s properties on this customer, as they stand now. What you write here is what you read back — another source’s values never appear in it and can never be overwritten through it. properties_by_source has everyone’s.
  - properties_by_sourceobject
    Every source’s properties on this customer, keyed by source slug — including your own. Read-only: a write only ever reaches the source it is attributed to.
  - signed_up_attimestamp
    When the customer signed up for the product — the signed_up_at property, resolved the same way as name. Write properties.signed_up_at to set it; a billing provider’s source writes the moment it first saw the customer, and a project’s own source outranks it. A customer who has signed up and never subscribed is trialing.
  - statusenum
    Where the customer stands with us, derived from what is live now: paying, free, churned, trialing or lead. A subscription is live while its status is active; paying and free are told apart by mrr, so paying means on a paid plan, whether or not an invoice has been settled. A customer with nothing live who has subscribed before is churned; one on a trial, or who has signed up and never subscribed, is trialing; anyone else is a lead. A change undone inside the project’s collapse window never happened to the status either.
    
    One of paying, free, churned, trialing, lead

- started_attimestamp
  When the subscription began — derived, not reported.
  
  It is the earliest instant anything was asserted about the subscription or its items. A source cannot say it began earlier than it described it: send the earliest write with effective_at at the real start instead, which is what an import of history does anyway.
  
  It moves earlier when a later write describes an earlier moment.
