HubSync
HubSync is an AI-powered, end-to-end tax and accounting workflow platform built for CPA firms, founded in 2019 by John McGowan and headquartered in Franklin, Tennessee. The SaaS platform unifies the engagement lifecycle in one interface: engagement letter generation and tracking, tax organizers and prepared-by-client data collection, document management, e-signature (including IRS Form 8879), batch federal and state extensions, tax return breakup and delivery, e-file status tracking, web-based tax workpapers, firm analytics dashboards, and integrated bill-and-pay. Its HubSync Halo layer adds agentic AI orchestration across those stages. HubSync publishes an llms.txt and states that it ships a Model Context Protocol (MCP) server and bi-directional API integrations with CCH Axcess/ProSystem fx, Thomson Reuters GoSystem/UltraTax and SurePrep, but it publishes no public developer portal, API reference, OpenAPI description or endpoint documentation — the entire integration surface is provisioned per customer firm.
HubSync is profiled on the APIs.io network. Tagged areas include Company, Tax, Accounting, Workflow-Automation, and Document-Management.
HubSync’s developer surface includes engineering blog, support, and 12 more developer resources.
