Rutter

Rutter is a Unified API that lets B2B software read and write data across accounting, ERP, commerce, payments, and ads platforms through a single data model, replacing the need to build and maintain separate integrations for each system. It supports use cases such as bank feeds, accounting automation, expense management, bill pay, invoicing, sales tax, lending and underwriting data, and supplier enablement.

The platform includes Rutter Link, a white-labeled end-user authentication flow that handles permissions, consent, and data governance; a monitoring and observability dashboard covering authentication, data access, webhooks, and data syncs; and Custom Fields, Platform Data, and API passthrough for accessing source data outside the common schema. The integration library spans platforms including QuickBooks, NetSuite, Sage Intacct, Xero, Shopify, Stripe, PayPal, Square, Meta Ads, and Google Ads. Rutter MCP connects Claude, ChatGPT, and Cursor to a Rutter account for debugging connections and checking platform support in plain English.

Rutter is aimed at fintechs, banks, and B2B SaaS companies building financial products. Pricing is based on connection volume, growth in connections, product capabilities, and platforms integrated. A free Starter Plan provides 30 days of building with sandbox data and a limited set of accounting integrations; a Full Access Plan with custom quoting adds unlimited live production access, all platforms, integration management tools, onboarding guidance, and support.
