Show HN: MoneyCo – A coding agent built for accounting

MoneyCo, a coding agent for accounting built by Mert and posted as a Show HN under HN AI Agents, is available at thecompany.money. It connects to multiple QuickBooks Online and Xero accounts by default and is meant for bookkeeping through an agent rather than through a general chat interface.

The product is framed around how bookkeeping actually runs across tools. Accountants Mert spoke with tried Claude, Codex, Hermes, and OpenClaw and hit the same frictions: QBO and Xero MCP integrations that are brittle and expose only limited access, setups that they could only get working locally, and LLMs that are weak at math. MoneyCo’s pitch is multi-account QuickBooks and Xero access as a default path so bookkeeping work does not depend on fragile, partial MCP wiring.

For engineers and builders, the gap is not “another chatbot for finance.” It is reliable multi-tenant connections to production ledgers, non-local operation so staff do not have to run agents on their own machines, and handling of numerical work that generic coding agents still mishandle. Anyone shipping agent tools against QBO or Xero is shipping against the same brittleness and access limits those MCPs already show.

The competitive field Mert names is Claude, Codex, Hermes, and OpenClaw used as general coding or agent stacks, not purpose-built accounting systems. MoneyCo sits where those tools fail for bookkeepers: multi-account QuickBooks and Xero by default, bookkeeping as the primary workflow, and an attempt to route around MCP brittleness, local-only runs, and weak math rather than asking accountants to glue those pieces themselves.

Watch whether multi-account QBO/Xero access holds up under real books, whether the agent stays usable outside a local install, and how it deals with numerical errors that already block accountants on Claude, Codex, Hermes, and OpenClaw. Those three failure modes—brittle limited MCPs, local-only setups, and bad math—are the bar this Show HN has set for itself.
