## Summary

YC-backed practice management platform for bookkeepers integrating with QuickBooks and Xero; $12M raised from Lattice/Front/Plaid founders automating month-end close and client communication.

## Company Overview

Double is an Austin-based practice management platform purpose-built for bookkeepers and accountants — providing client communication tools, month-end close workflow automation, and advisory service delivery infrastructure that replaces the combination of email, spreadsheets, and disconnected apps that most accounting practices cobble together. Founded in 2020 and a Y Combinator graduate, Double has raised $12 million from investors including founders of Lattice, Front, Superhuman, and Plaid, serving thousands of accounting professionals managing books for startups and small businesses across the United States.

Double integrates natively with QuickBooks and Xero — the dominant bookkeeping software — to pull live client financial data into Double's client portal and workflow engine. The platform provides standardized month-end close checklists, automated client document requests, recurring task management, and a client-facing portal where business owners can view their financials, approve transactions, and communicate with their bookkeeper. This eliminates the back-and-forth email chains that consume bookkeeper time while creating a professional client experience that supports premium pricing.

In 2025, Double competes in the accounting practice management market with Canopy (practice management for tax and accounting firms), TaxDome (all-in-one accounting firm platform), and Karbon (accounting workflow automation) for professional services workflow software. The accounting profession has been slower than other industries to adopt SaaS workflow tools — most bookkeepers still use email and Dropbox for client collaboration. Double's YC-backed founder network gives it distribution among venture-backed startup founders who want modern bookkeeping experiences. The 2025 strategy focuses on deepening the QuickBooks/Xero integration, growing the advisory services delivery features that help bookkeepers evolve from compliance work to higher-value advisory, and building the automation that reduces month-end close time for bookkeepers managing large client portfolios.
