- Suggested payment source, category and payee per import
- Approve in a batch with shared defaults
- Duplicate posts are collapsed by idempotency key
- Series with expected amounts and due dates
- Lead-up reminders days before the date
- Snooze, skip or post an occurrence as it happens
- Income, expense, net and closing balance per period
- Category movements and flagged anomalies
- Compare two versions of the same period side by side
- Holdings, allocation and watchlist
- Historic valuations over time
- Net worth across accounts and positions
Built for One Household's Books
JAG Finance started because off-the-shelf apps flatten a receipt into a single number. It keeps the detail instead, and every feature exists because it was needed for real day-to-day bookkeeping.
Invite-only
Sign-in is limited to an allowlist, so the app stays a private set of books.
Privacy First
One database, no bank connections and no third-party analytics on your ledger.
Mobile Ready
Installable as a PWA, with offline pages and push notifications on your phone.
Versioned history
Period summaries are stored per version, so a later backfill never rewrites what you already read.
Private by Design
JAG Finance is a personal project rather than a product for sale. That shapes how you get in and what happens to your data.
