### Which general ledgers does Meridian work with?

Meridian currently supports QuickBooks Online and Xero. Support for NetSuite, Sage Intacct, QuickBooks Desktop, Rillet, and additional or custom ledgers is in development. Meridian separates ledger-specific connectors from its accounting workflows, which makes it straightforward to add a ledger while preserving the depth required for subledgers, dimensions, schedules, write-back, and review. Firms with mixed portfolios or a priority ledger on this list should talk to Meridian about their requirements and the development roadmap.
