## StockMovement
A StockMovement is created whenever stock of a particular ProductVariant goes in
or out.
```ts title="Signature"
class StockMovement extends VendureEntity implements HasCustomFields {
@Column({ nullable: false, type: 'varchar' })
readonly type: StockMovementType;
@Index()
@ManyToOne(type => ProductVariant, variant => variant.stockMovements)
productVariant: ProductVariant;
@Index()
@ManyToOne(type => StockLocation, stockLocation => stockLocation.stockMovements, { onDelete: 'CASCADE' })
stockLocation: StockLocation;
@EntityId()
stockLocationId: ID;
@Column()
quantity: number;
@Column(type => CustomStockMovementFields)
customFields: CustomStockMovementFields;
}

## Allocation
An Allocation is created for each ProductVariant in an Order when the checkout is completed
(as configured by the [StockAllocationStrategy](/current/core/reference/typescript-api/orders/stock-allocation-strategy#stockallocationstrategy). This prevents stock being sold twice.
```ts title="Signature"
class Allocation extends StockMovement {
readonly type = StockMovementType.ALLOCATION;
constructor(input: DeepPartial)
@Index()
@ManyToOne(type => OrderLine, orderLine => orderLine.allocations)
orderLine: OrderLine;
}
```
* Extends: [`StockMovement`](/current/core/reference/typescript-api/entities/stock-movement#stockmovement)
### type
\
### orderLine
\OrderLine`} />
## Cancellation
A Cancellation is created when OrderItems from a fulfilled Order are cancelled.
```ts title="Signature"
class Cancellation extends StockMovement {
readonly type = StockMovementType.CANCELLATION;
constructor(input: DeepPartial)
@ManyToOne(type => OrderLine, orderLine => orderLine.cancellations)
orderLine: OrderLine;
}
```
* Extends: [`StockMovement`](/current/core/reference/typescript-api/entities/stock-movement#stockmovement)
### type
\
### orderLine
\OrderLine`} />
## Release
A Release is created when OrderItems which have been allocated (but not yet fulfilled)
are cancelled.
```ts title="Signature"
class Release extends StockMovement {
readonly type = StockMovementType.RELEASE;
constructor(input: DeepPartial)
@ManyToOne(type => OrderLine)
orderLine: OrderLine;
}
```
* Extends: [`StockMovement`](/current/core/reference/typescript-api/entities/stock-movement#stockmovement)
### type
\
### orderLine
\OrderLine`} />
## Sale
A Sale is created when OrderItems are fulfilled.
```ts title="Signature"
class Sale extends StockMovement {
readonly type = StockMovementType.SALE;
constructor(input: DeepPartial)
@ManyToOne(type => OrderLine, line => line.sales)
orderLine: OrderLine;
}
```
* Extends: [`StockMovement`](/current/core/reference/typescript-api/entities/stock-movement#stockmovement)
### type

### orderLine
\OrderLine`} />
## StockAdjustment
A StockAdjustment is created when the `stockOnHand` level of a ProductVariant is manually adjusted.
```ts title="Signature"
class StockAdjustment extends StockMovement {
readonly type = StockMovementType.ADJUSTMENT;
constructor(input: DeepPartial)
}
```
