What's inside:
- 🧾 Invoice register with auto sequential numbering (INV-2026-001) and a custom prefix
- 💲 Full & partial payment tracking with an auto-calculated balance and % paid progress bar
- 🟡 Automatic status: Draft → Sent → Partially Paid → Paid, and auto-flips Overdue past the due date
- 👤 Client database — total billed, paid, outstanding, and average days-to-pay per client, so you know who owes you the most and who always pays late
- 📊 Automated dashboard with 5+ charts: outstanding vs paid, income by month (with a year picker for tax-time review of past years), income by client, invoices by status, aging
- 📈 Aging report — 0–30 / 31–60 / 61–90 / 90+ days, so "very late" never sneaks up on you
- ⏰ Optional late fees that accrue on the unpaid BALANCE — a partial payment doesn't let an overdue invoice off the hook
- 📅 Smart calendar of due dates, color-coded, filterable to overdue-only — picking a client auto-fills the due date from their Net terms, with Due today / Net 7 / 14 / 30 quick-tap chips
- 🖨️ Printable invoices — turn any tracked entry into a clean, print/PDF-ready invoice with your business header
- 📋 Copy-paste chase-list reminders — polite, pre-written reminder text you actually send
- 🪙 Deposit & custom-order friendly — record a 40% deposit, track the remaining balance to the cent

Also:

- 📤 CSV export for your accountant + full JSON backup/restore
- 💱 Single currency-symbol setting and a toggleable tax field — stays simple, never bloated

🔒 Private & yours — no account, no internet, no subscription. Your client and payment data lives in one file you own, on your device. Requirements: a modern browser (Chrome, Edge, Firefox, Brave; Safari with a one-time fix).

🎁 A great gift for — the freelancer who's tired of chasing payments; the maker selling wholesale or custom orders; the photographer, cleaner, tutor, or VA who invoices clients; the self-employed parent who'd rather not run accounting software.

How it works: 1) Buy → 2) Receive your personalized HTML file → 3) Open it in your browser → 4) Add clients and invoices and see who owes you what.

This tool tracks amounts, dates, and statuses — it does not provide tax, legal, or accounting advice.
