Agent-ready accounting tools
We scanned 10 accounting, bookkeeping and invoicing software the way an AI agent would, and scored how well ChatGPT, Claude and Perplexity can read each one, sign a team up and connect through the API.
Which accounting software is best for AI agents?
It depends on what you need agents to do. If you want an agent to sign your team up and connect through the API, Digits scores highest (92/100), followed by Puzzle (79) and Zoho Books (74). Digits and Puzzle run remote MCP servers agents can connect to directly. QuickBooks, Xero and Sage block AI agents with a bot wall, so assistants can't read their sites at all. Scores as of 20 Oct 2026.
