Double

Accounting workflow automation with QuickBooks/Xero

Overview

Double provides an all-in-one platform for professional firms to communicate with clients, catch coding errors, manage receipts, and streamline workflows. It integrates with QuickBooks Online and Xero through a two-way sync to connect to clients’ ledger files and reduce the time spent on month-end close by 50%. How it works: the product ties together client communications, error checking, receipt management, and workflow automation in a single system, syncing data bidirectionally with accounting ledgers so information stays up to date. How it’s different: its core value comes from offering a single, connected workspace that directly links to major accounting platforms and ledger files, delivering substantial time savings without needing multiple separate tools. Its goal: help firms close their books faster and more accurately by centralizing critical accounting tasks in one platform.

Double raises $6.5M Series A to streamline accounting workflows with AI-powered close management platform

Double, formerly Keeper, has raised $6.5 million in a Series A round led by Album Ventures, with participation from Y Combinator and Jack Altman, co-founder and CEO of Lattice. The funding brings total capital raised to over $12.5 million. The New York-based startup provides a close management and practice management platform for accounting and bookkeeping firms. Its software automates repetitive tasks, centralises client data and streamlines month-end closing processes whilst preserving human judgement. Double serves over 4,000 firms across North America and maintains 150% net-dollar retention. The company rebranded from Keeper in October 2024 to reflect its mission of doubling accountants' capacity and accuracy. The new funding will accelerate product development, expand teams and enhance AI-powered features for financial reporting.
