# List bills

`GET /companies/{companyId}/data/bills`

The *List bills* endpoint returns a list of [bills](https://docs.codat.io/accounting-api#/schemas/Bill) for a given company's connection.

[Bills](https://docs.codat.io/accounting-api#/schemas/Bill) are invoices that represent the SMB's financial obligations to their supplier for a purchase of goods or services.

Before using this endpoint, you must have [retrieved data for the company](https://docs.codat.io/codat-api#/operations/refresh-company-data).

### Tips and traps

To access the `paymentAllocations` property, ensure that the `billPayments` data type is queued and cached in Codat before retrieving `bills` from Codat's cache.
