Select a source
Direct bank aggregation, Android banking notifications, transaction emails and statement imports each expose different data. Notification and email approaches can work without bank credentials, but depend on the messages your bank provides.
Recognize, then review
A transaction parser may extract amount, currency, merchant, date and account hints. A good workflow shows uncertain results instead of silently treating every message as correct. Review is especially important for refunds, transfers, reversals, fees and foreign-currency alerts.
Plan for duplicates
The same purchase may appear as a push notification, an email and later a statement row. Use stable source identifiers and transaction details to detect likely duplicates, but keep a way to inspect ambiguous cases.
Keep a manual fallback
Cash, missing notifications, unsupported formats and delayed messages will still occur. Automation is sustainable when manual correction is quick and does not require maintaining a second ledger.
Stash's approach
Stash can process selected Android notifications and optional Gmail transaction emails into reviewable candidates. It does not require a direct bank-account connection, and its recognition pipeline runs on the Android device.
