Send a professional invoice in under a minute โ€” and keep your money. FairInvoice is the honest way to bill your own clients: unlimited invoices free forever (no "three free, then pay" bait), no account, and a fair pay-once option for Pro. Your paperwork belongs to you; we don't rent it back. DESCRIBE THE JOB, CHECK THE DRAFT Type or say one sentence about the job and Describe It drafts the invoice or estimate for you to check. Scan Lines turns a photo of a supplier receipt or handwritten quote into lines you pick. Write a Reminder drafts a polite payment reminder in your client's language. All on your device with Apple Intelligence, nothing sent to a server; shown where it's available (iOS and macOS 26, supported languages). 5 free drafts and 3 free reminders, then Pro. WATCH YOUR INVOICE BUILD ITSELF Type a line item and the PDF updates in front of you. On iPad and Mac, the form sits beside a live preview of the real PDF. GET PAID, NOT JUST INVOICED The dashboard totals what you're owed, flags overdue invoices and charts what you've been paid. Put a payment link and QR code on your PDF so clients pay in a tap, get a nudge when an invoice slips past due, and set recurring invoices. Record deposits and partial payments โ€” every PDF shows Paid to date and Balance due. ESTIMATES THAT WIN THE JOB Send an estimate, get the nod, then convert it to an invoice in one tap, linked both ways. Estimates are Pro; your first one is free. LOOK PROFESSIONAL Six clean PDF designs. Your logo, your exact brand color and typeface, payment instructions on the PDF, and a signature drawn or typed on screen. Your currency and date format, full right-to-left support. ON YOUR MAC, IN SYNC A native Mac app too, with a desktop widget and keyboard shortcuts. iCloud Sync (Pro) keeps your invoices, clients and items on iPhone, iPad and Mac through your own iCloud. Or export one backup file and restore it anywhere โ€” free. TAX TIME, HANDLED The Income Report totals what you've been paid by year, quarter or any range, with tax collected and per-client totals, as PDF or CSV. Optional reminders keep quarterly estimated-tax dates on your radar. YOURS. PRIVATE. OFFLINE. No account, no sign-in. Everything stays on your device โ€” and, only if you turn on iCloud Sync, in your own iCloud, never on our servers. We receive only anonymous usage statistics, crash reports and a device record our own server registers at launch (a random ID, app and OS version, language, time zone and your announcements choice), and โ€” only if you choose to answer it โ€” one optional question when you cancel Pro. Never your documents, never linked to you. Announcements are opt-in; if you allow notifications, a push token is added. Feedback you send from Settings reaches us with the email you give, so we can reply. FREE FOREVER Unlimited invoices, payment receipts, clients and saved items; the Ledger design as a clean PDF; the who-owes-me dashboard and widget; backup and restore to a single file; quarterly tax-date reminders; one estimate to try. FAIRINVOICE PRO โ€” PICK HOW YOU PAY All six designs, an exact brand color and fonts, your logo, no footer credit, unlimited estimates, AI drafts and reminders, iCloud Sync, deposits and partial payments, pay-by-QR, the Income Report, signatures, CSV export, number prefixes and larger widgets. - Monthly โ€” $2.99/month - Yearly โ€” $19.99/year (best value; any free trial is shown before you buy) - Lifetime โ€” $29.99 once. Yours forever. Not a subscription, never renews. Subscriptions auto-renew until canceled; cancel anytime in your App Store settings, at least 24 hours before the current period ends. FairInvoice creates and organizes your billing documents; payment instructions on your PDFs are between you and your client โ€” the app never touches the money.
