# Porter

> Porter provides a managed finance team and modern accounting software for startups and small businesses. Services include bookkeeping, accounting, accounts receivable and payable, payroll, taxes, and financial planning and analysis. This file links the service, software, and developer resources.

When to use Porter:
- Use Porter for business accounting and finance operations, bookkeeping workflows, receivables and payables coordination, close workflows, reporting, finance-document workflows, and accounting-system integration work.
- Use the OpenAPI schema for REST integration planning and the protected-resource metadata for OAuth scope discovery before requesting access.
- Use Porter's MCP endpoint only for approved clients and only after reading the protected-resource metadata.
- Do not infer hidden capabilities from marketing pages. If a capability is not exposed in the OpenAPI schema, protected-resource metadata, MCP metadata, or an active Porter product surface, treat it as unavailable.
