## Context A production customer was stuck on the billing settings page: their workspace was `SUSPENDED` (with `suspendedAt` set) while their subscription was `active` in the database. ## Problem Stripe webhook events can be delivered out of order or processed concurrently ([Stripe explicitly does not guarantee ordering](https://docs.stripe.com/webhooks#events-ordering)), and `BillingWebhookSubscriptionService.processStripeEvent` made its suspend/reactivate decision from stale and incomplete data: - The decision used the **event payload's** subscription status, while the subscription row was upserted from a **live Stripe fetch** — so the two could diverge. Around trial end, Stripe emits `active → past_due` then (once the customer pays) `past_due → active` within a short window. If the stale `past_due` event is processed last, it suspends the workspace while writing an `active` subscription to the DB. Nothing self-heals from that state: the workspace stays suspended while the cleanup cron warns and eventually soft-deletes it. - The decision only looked at the **event's own subscription**, but suspension is a workspace-level decision and a Stripe customer can hold several subscriptions (plan switch, cancel-then-resubscribe). A `customer.subscription.deleted` event for the old subscription is *genuinely* canceled — only the sibling subscription proves the customer is still paying. - The workspace snapshot was read at the top of the handler, before several slow awaits, so a concurrent event could change it mid-flight. ## Fix Every event now converges the workspace to the current Stripe state, regardless of delivery order: - **Live input**: fetch the customer's not-ended subscriptions from Stripe (`subscriptions.list` without a `status` param excludes the unbounded canceled history server-side; an explicit `NOT_ENDED_SUBSCRIPTION_STATUSES` filter additionally drops `incomplete_expired`, which would otherwise block suspension forever since it is neither suspend-worthy nor activating). The event's subscription is taken from that list, or fetched directly by id when absent (deletion events, deleted customers) — same retrieve the code used before. The DB upsert uses this live object, never the payload. - **Workspace-level decision over all live subscriptions**: suspend only when **every** subscription warrants it, reactivate as soon as **one** is activating (`active`/`trialing`), and deliberately do nothing in between — e.g. a `past_due` subscription in its payment-retry grace period blocks suspension without triggering reactivation. - **Guarded transitions (compare-and-swap)**: `WorkspaceService.suspendWorkspace`/`reactivateWorkspace` now apply their UPDATE only when the workspace is still in a state the transition is valid from, and return whether they applied. Repeated suspensions keep the first `suspendedAt` so the cleanup countdown stays anchored to the original suspension date; the deletion-warning cleanup job is only enqueued when a reactivation actually applied. The suspend path re-reads the workspace right before deciding and switches exhaustively on `activationStatus` (`assertUnreachable` in `default`), preserving the previous behavior including suspend-over-reactivate precedence. ## Tests Unit tests cover the incident scenario and its neighbors: a stale `past_due` event after payment reactivates instead of suspending; a live `unpaid` state suspends even when the payload says `active`; a canceled subscription event does not suspend (and reactivates) when a sibling `active`/`trialing` subscription exists; a sibling in `past_due` grace blocks suspension without reactivating; the direct-retrieve fallback handles subscriptions absent from the customer list; the guarded reactivation skips the cleanup job when it did not apply; and soft-deleted workspaces are never transitioned.

Why Twenty
Twenty gives technical teams the building blocks for a custom CRM that meets complex business needs and quickly adapts as the business evolves. Twenty is the CRM you build, ship, and version like the rest of your stack.

Installation
Cloud
The fastest way to get started. Sign up at twenty.com and spin up a workspace in under a minute, with no infrastructure to manage and always up to date.
Build an app
Scaffold a new app with the Twenty CLI:
npx create-twenty-app my-app
Define objects, fields, and views as code:
import { defineObject, FieldType } from 'twenty-sdk/define';
export default defineObject({
nameSingular: 'deal',
namePlural: 'deals',
labelSingular: 'Deal',
labelPlural: 'Deals',
fields: [
{ name: 'name', label: 'Name', type: FieldType.TEXT },
{ name: 'amount', label: 'Amount', type: FieldType.CURRENCY },
{ name: 'closeDate', label: 'Close Date', type: FieldType.DATE_TIME },
],
});
Then ship it to your workspace:
npx twenty app:publish --private
See the app development guide for objects, views, agents, and logic functions.
Self-hosting
Run Twenty on your own infrastructure with Docker Compose, or contribute locally via the local setup guide.
Everything you need
Twenty gives you the building blocks of a modern CRM (objects, views, workflows, and agents) and lets you extend them as code. Here's a tour of what's in the box.
