Budget Overview
The Ledger: Nested Accounts
The left card is your ledger—every income and expense line. Use Category::Subcategory to organize (Housing::Mortgage, Income::Salary). No chart of accounts to memorize—you build as you go, nest as deep as you need. Monthly Savings is what you can put toward a down payment or emergency fund.
Budget Overview: Executive Report
The right card is the Account Summary—the same data rolled up by category. Expand the chevron to see detail (Mortgage, Insurance, Property Tax under Housing). One view answers "How much am I spending on housing?" and "What's left?"—with drill-down when you need it. Full clarity on your finances—without the complexity.
Ledger Overview
The Overview page shows all your ledgers at a glance. Each card summarizes income and expenses by category. Click a card to drill into the full Account Summary Report. Create as many ledgers as you need—one for household expenses, one for a rental property, one for a side business. Each one gets its own summary.

Full Ledger View
In the app, you add entries to your ledger, organize them with nested accounts, and watch your Budget Overview update in real time.
Import & Export
Import and export to JSON—by design, for security. Your data stays in your browser's persistent storage. You own it.
Why not spreadsheets?
Spreadsheets are great at rows and columns. But they can't nest your accounts into a hierarchy, roll up subcategories automatically, or generate a summary report that drills down from Housing to Mortgage to Insurance in one click. Budget Sidekick does all of that—no formulas, no pivot tables, no setup. You enter the numbers. We build the reports spreadsheets can't.
Start with a Budget
Track your income. Track your expenses. See what's left. A budget doesn't have to be perfect—it just has to start.
Add your numbers and watch your overview update in real time. When you know your numbers, you move forward with confidence.
