Unified Accounting API

One Unified Accounting API to integrate with Netsuite, Quickbooks, and all your customers’ favorite Accounting tools.

Powering Global SaaS Organizations

What is a 

Unified Accounting API

Every accounting platform - QuickBooks, Xero, NetSuite, Zoho Books - stores financial data differently, with its own authentication methods, schemas, and APIs. Building separate integrations for each takes months of engineering work and ongoing maintenance as APIs evolve.

A Unified Accounting API standardizes these differences into a single interface. Integrate with Knit once to access multiple accounting platforms through one unified data model.

Your team works with a single API while Knit handles translation, rate limiting, retries, and sync management behind the scenes.
