Where each falls short
The honest trade-offs — what you give up with each, versus the proprietary tools they replace.
Fava
- All data entry is in plain-text Beancount syntax; no GUI transaction entry out of the box
- No automatic bank import; requires manual or third-party import scripts
- Steep learning curve for Beancount format and double-entry concepts
- No mobile app; purely browser-based
Lago
- Developer-oriented billing API, not a personal finance or budgeting tool for end-users
- No AR/AP or general-ledger accounting; revenue recognition requires integration with an ERP
- Tax calculation engine is basic; real-world tax compliance needs third-party integration (e.g. Avalara)
- Dunning workflows and payment retries are less mature than Chargebee or Stripe Billing
Bottom line
