Mercury has introduced Mercury Books, a double-entry accounting platform that integrates directly into its existing digital banking services. The software uses artificial intelligence to manage transaction categorization and reconciliation for users.

Why it matters

The platform aims to eliminate manual data entry and reconciliation by importing financial activity directly from banking, card, and payment platforms into a single accounting view. This consolidation seeks to provide businesses with real-time financial reporting.

Mercury Books is available at no cost to business customers through the end of 2026, after which the service will cost $35 per month. The platform provides unlimited accountant seats at no cost to help businesses manage their financial records.
