About

Invoice Tracker

Features
Read full description

Every freelancer knows the feeling: you sent the invoice weeks ago, and you genuinely cannot remember whether it was paid. InvoiceNotes is an invoice tracker that answers that in one glance — who owes you, how much, and which invoices slipped past their due date. No account, no cloud, no client portal to configure. Add an invoice in seconds — client, amount, sent and due dates — and the dashboard keeps a running total of what you're owed. The moment a due date passes, the invoice flags itself Overdue. You never update a status by hand, and you never chase money you already received. WHAT YOU GET • A dashboard that always knows your number: total outstanding, split by currency, the second you open the app • Overdue status that sets itself — an invoice one day late turns red on its own, with "3 days overdue" spelled out • A local reminder the day before an invoice is due and another the morning it turns late, so following up stops depending on memory • A clean, paginated A4 PDF of any invoice, with your business details and tax number in the FROM block, ready to share straight from the detail screen • Itemised invoices with quantities, unit prices, your own tax rate and discounts — totals recalculate to the exact cent • A monthly income summary showing what actually got paid each month and what is still hanging PERFECT FOR • Freelancers juggling a handful of clients who pay on wildly different schedules • Side-hustlers who invoice a few times a month and refuse to run accounting software for it • Contractors and tradespeople who need a presentable PDF on the spot • Anyone whose current system is "scroll the sent folder and hope" WHY NOT JUST A SPREADSHEET? A spreadsheet never taps you on the shoulder. It won't notice a due date passed, won't remind you the day before, and won't hand your client a numbered, professional PDF. InvoiceNotes does all three — and invoice numbers are issued sequentially and never reused, so your records stay audit-friendly without you thinking about it. PRIVATE BY DEFAULT Your ledger is your business — literally. Everything stays in on-device storage. No account, no server, no analytics on your clients or your income. Back up your iPhone and your records are backed up too. FULL ACCESS InvoiceNotes Pro unlocks unlimited invoices, itemised invoicing with tax and discount rates, and the monthly income summary. Choose a weekly or yearly subscription, or a one-time lifetime purchase. Subscriptions renew automatically and can be cancelled anytime in your Apple ID settings. Add the invoice you're waiting on right now — the next time you wonder "did they ever pay that?", the answer is already on screen.
