# Lifecycle of a Service

URL: /products/service/lifecycle · Id: `page:products/service/lifecycle`

> The states a Service, each Order and each line move through, and who holds the next move in each.

A [Service](/business/nouns/service) has three lifecycles: the product's, set by its [Offers](/business/nouns/offer); each [Order](/business/nouns/order)'s, for the money; and its `fulfillment`, for the work. Each work state says who holds the next move.

## The product

The Service is `draft` until a published Offer sells it, and [`Offer.publish`](/business/nouns/offer/publish) refuses an Offer whose promise its checks cannot back. It is `retired` when its last Offer is withdrawn, and every placed Order keeps the terms it was bought under.

## The money

Payment is authorized when the Order is placed or the [Quote](/business/nouns/quote) accepted, and captured line by line on `Order.confirmed`. A refund before that [Event](/business/nouns/event) releases the authorization, so no revenue was counted.

## The work
| `fulfillment` | Holds while | Next move | Moved by |
| --- | --- | --- | --- |
| `intake` | The inputs are checked against the brief | The buyer, when an input is missing | [`Order.start`](/business/nouns/order/start) |
| `working` | The steps run and their checkers grade them | The [Startup](/business/nouns/startup) | [`Order.deliver`](/business/nouns/order/deliver) |
| `delivered` | The acceptance window is open | The buyer | [`Order.confirm`](/business/nouns/order/confirm), [`Order.revise`](/business/nouns/order/revise), [`Order.dispute`](/business/nouns/order/dispute) |
| `revising` | A revised line is redone, its window paused | The Startup | `Order.deliver` |
| `accepted` | The line is confirmed and earned | Nobody | None |
| `disputed` | The remedy runs and the fee is held | The Startup | The contract's remedy |

The clock charges each delay to whoever holds the next move. [Deadline clocks](/products/service/deadline-clocks) has the rule.

The work states live on the Order's `fulfillment`. A work [Thing](/business/nouns/thing) of its own, such as a catalog audit that callers watch apart from the commercial Order, has status `planned`.

## Open, pause, close
A Service also opens to new Orders, pauses at capacity and closes. [Service capacity](/products/service/capacity) has the [Verbs](/business/nouns/verb), with status `planned`. [`Offer.withdraw`](/business/nouns/offer/withdraw) stops new Orders, and every placed Order runs to its end.
