This endpoint allows specifying multiple time periods (specified in months, years, or custom date ranges) and tags and will generate a comparison for every combination. Note that this endpoint is retrieval only, but uses a `POST` HTTP verb rather than `GET` because of the complexity of the parameters. ## OpenAPI ````yaml post /v1/businesses/{businessId}/reports/profit-and-loss-comparison openapi: 3.0.1 info: title: API version: latest servers: [] security: - BearerAuth: [] tags: [] externalDocs: url: / paths: /v1/businesses/{businessId}/reports/profit-and-loss-comparison: post: tags: [] summary: Create P&L comparisons description: >- Compare Profit & Loss views across time periods and/or tags.
