Send a professional invoice in under a minute β€” and keep your money. FairInvoice is the honest way to bill your own clients: unlimited invoices free forever, no account, and a fair pay-once option for Pro. Your paperwork belongs to you; we don't rent it back. WATCH YOUR INVOICE BUILD ITSELF Type a line item and the finished PDF updates in front of you. On iPad and Mac the editor splits in two: the form on one side, a live preview of the real PDF on the other. UNLIMITED INVOICES, FREE FOREVER No monthly invoice cap. No "three free, then pay" bait. Create as many invoices as your work needs, and share them as clean PDFs. SEE WHO OWES YOU The dashboard totals what's outstanding, flags overdue invoices with days-late badges, and charts what you've been paid by month. GET PAID, NOT JUST INVOICED Put a tappable payment link and a scannable QR code right on your PDF so clients pay in a tap, get a nudge when an invoice slips past due, and set recurring invoices for the clients you bill every month. Record deposits and partial payments β€” 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 β€” client, line items and numbers carry over, linked both ways. Estimates are a Pro feature; your first one is free to try. LOOK PROFESSIONAL Six clean PDF designs. Add your business logo, set your brand color and typeface, put your payment instructions right on the PDF, and sign on screen β€” draw it or type it. Your currency, your date format, full right-to-left support. ON YOUR MAC, IN SYNC FairInvoice is a native Mac app too, with a desktop widget and keyboard shortcuts. Turn on iCloud Sync (Pro) and the same invoices, clients and items follow you across iPhone, iPad and Mac β€” through your own iCloud, never our servers. Or export a single backup file anytime and restore it anywhere β€” free. TAX TIME, HANDLED The Income Report totals what you've been paid by year, quarter or any date range, with tax collected and a per-client breakdown, exported as PDF or CSV. Optional reminders keep the quarterly estimated-tax dates on your radar. YOURS. PRIVATE. OFFLINE. No account, no sign-in. Everything stays on your device β€” 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) β€” never your documents, never linked to you. Announcements are opt-in. If you allow notifications, a push token is added. FREE FOREVER - Unlimited invoices and payment receipts - Unlimited clients and saved items - The Ledger design, shared as a clean PDF - The who-owes-me dashboard and widget - Back up and restore to a single file - Quarterly tax-date reminders - One estimate to try FAIRINVOICE PRO β€” PICK HOW YOU PAY All six designs, brand colors and fonts, your logo, no footer credit, unlimited estimates, iCloud Sync, deposits and partial payments, pay-by-QR, the Income Report, signatures, CSV export, custom number prefixes and the larger widgets. - Monthly β€” $2.99/month - Yearly β€” $19.99/year (best value; any free trial is shown before you buy) - Lifetime β€” $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. WHO IT'S FOR Handymen, landscapers, cleaners, electricians, freelancers β€” anyone who bills their own customers and would rather keep the money than rent an app. FairInvoice creates and organizes your billing documents; payment instructions on your PDFs are between you and your client β€” the app never touches the money.
