CatSimba vs. Double (formerly Keeper)
A ledger-connected close workflow and a bank-data-to-workpaper workflow have different starting points.
What the other tool does
Double supports accounting firms and internal finance teams, integrates with QuickBooks Online, Xero, Sage and NetSuite, and includes review, client communication and 1099 workflows. Its official material also describes a white-labeled client portal.
Where CatSimba differs
CatSimba’s core starts with supported bank spreadsheets and cash-basis categorization, without requiring a separate QBO/Xero ledger. Schedule C-ready workpapers, optional AI and per-client Standard upgrades define its scope.
Choose for the workflow you need
Double may suit firms already standardized on those ledgers and broader close processes. CatSimba may suit a professional handling cash-basis clients from source data. Neither comparison should imply Double lacks bank automation, W-9 collection or portal branding.
