Built for families and individuals who want full control over their financial data without compromising on features.
Single-entry, account-based transaction ledger. Balances computed by account, with optional category splits and virtual accounts for flexible tracking.
Household-level accounts with multiple logins. Owner, Member, and Viewer roles keep everyone in the loop with the right level of access.
Every account has a base currency. Transactions can be in any currency with automatic or manual exchange rate overrides.
CSV, QIF/QFX, Google Sheets, and OFX. Preview every transaction before committing — fix categories, amounts, and dates first.
Hierarchical categories with parent/child relationships. Flexible tags for cross-cutting concerns like "tax-deductible" or "vacation."
Net worth tracking, income vs. expense breakdowns, spending by category, and account balance trends — all from your dashboard.
Multi-Currency
Living abroad? Paid in multiple currencies? OtterFin treats multi-currency as a first-class feature, not an afterthought.
Import System
The #1 pain point with other finance tools? Importing messy data and having to clean it up after. OtterFin lets you fix everything first.
Family Accounts
Most finance apps are single-user. OtterFin is designed from the ground up for families managing money together.
