At Growbi, we spend a lot of time thinking about transparency — specifically, how to make learning progress visible and honest. A student’s quiz history should be clear to them, not locked inside an opaque system. Data should be inspectable. Progress should be auditable.

So when we came across beancount.io, we felt something click.

The idea is simple and kind of brilliant

Plain-text accounting means your financial records live in a text file. Plain prose, structured data, no proprietary binary format. Every transaction is a line you can read. Your entire financial history can sit in a Git repository.

“Write your finances like code” is their tagline, and it’s not just marketing — it’s a genuine design philosophy. If you’ve ever been frustrated that your bank’s CSV export looks different every quarter, or that your accounting app holds your data hostage, plain-text accounting is the antidote.

What beancount.io actually does

The open-source Beancount format has been around for years and has a loyal following among developers and finance nerds. What beancount.io adds on top is a full product experience:

• AI-assisted bookkeeping — automated transaction categorization and anomaly detection, so the tedious parts get handled
• Scriptable workflows — write custom automation for anything the defaults don’t cover
• Hosted Fava dashboard — Fava is the standard web UI for Beancount data; beancount.io hosts it for you so you’re not wrangling a local server
• Real-time analytics and dashboards — the kind of charts you’d otherwise build yourself in a spreadsheet
• Open-source mobile apps for iOS and Android

The free tier gets you started. Paid plans go from $14.99/month (Premium) up through Growth and Organization tiers for teams and firms.

Why this resonates with us

We build software for parents trying to help their kids prepare for standardized tests. One of our core beliefs is that the practice data — every question attempted, every mistake made — should serve the student, not a vendor. It should be readable, portable, and honest.

Plain-text accounting applies the same instinct to money. Your ledger shouldn’t be an abstraction managed by someone else’s cloud. It should be something you own, can inspect, can version-control, and can take with you.

There’s also something we appreciate about the Git-native angle. Version control for financial data means you have a complete audit trail. You can git blame a transaction. You can roll back an entry. You can branch and experiment. For anyone who thinks in code, this is genuinely freeing compared to dragging line items around in a spreadsheet.

Not for everyone — and that’s fine

To be clear: plain-text accounting has a learning curve. If spreadsheets already feel like too much, a double-entry ledger syntax might not be your thing. But if you’re a developer, a finance professional, or just someone who’s frustrated that their “personal finance app” can’t answer a custom question about their own spending — this is worth a look.

We’re rooting for tools that respect their users’ data. Beancount.io is one of them.
