Create professional invoices, estimates, and sale receipts for your own business, send them as PDFs, and track exactly who has paid. No account. No cloud. No tracking. Free to start, and Pro is one payment, never a subscription. Built for freelancers, contractors, and small businesses who want to bill a client in two minutes and get back to the work that earns the money. INVOICES, ESTIMATES, AND RECEIPTS Every document is issued by your business, in your name. Write an invoice for work you have done, send an estimate or quote before you start, or hand a customer a sale receipt on the spot. Add line items with quantities and rates, and watch the total update as you type. Set your own numbering, too. ACME-0001 instead of INV-0001, with a separate sequence for each document type, so your books read the way you keep them. SEND A PDF YOUR CLIENT WILL TAKE SERIOUSLY Every document renders as a clean, printable PDF invoice. Send it straight from the app by email, or push it through the share sheet into whatever your client actually uses. No watermark on any plan. GET PAID, AND SEE WHO HASN'T PAID Record part payments and full payments against any invoice and watch the balance fall. CustomInvoice works out paid, part paid, outstanding, and overdue from your payment record every time it shows them, so the number in front of you is never a stale total someone forgot to update. INVOICE TEMPLATES AND YOUR OWN BRANDING Start with the Classic template, free. Pro adds the Modern and Minimal templates and puts your logo and brand colour on every page, so your invoice looks like your business, not like an app. TAX RATES AND DISCOUNTS THAT ADD UP Create named tax rates and apply them per line, so a job that mixes taxable labour with exempt materials bills correctly. Discount a single line or the whole invoice. Every amount is calculated the way an accountant would check it. REPORTS, AND CSV FOR YOUR ACCOUNTANT See what you are owed at a glance, and export your documents and payments to CSV for your bookkeeper, free on every plan. Pro adds the aging report, how much is late and how late, and what you billed each month. BUILT TO BE TRUSTED WITH MONEY Every amount is a whole number of cents. Line totals are rounded individually and then added, so the total on the invoice always equals the column your client is reading. Document numbers are never reused, so your sequence stays an audit trail. PRIVATE BY DESIGN, AND GENUINELY OFFLINE CustomInvoice has no account, no login, and no cloud sync. Your clients, your rates, and your invoices live on your device and are never uploaded. The app works with the radio off: on a plane, in a basement, or on a site with no signal. Back everything up to one file you keep, and restore it on a new phone. WHO USES CUSTOMINVOICE Freelance designers, developers, and writers. Photographers and videographers. Electricians, plumbers, painters, landscapers, and cleaners. Tutors, coaches, therapists, and consultants. Market traders and makers. Anyone self employed who invoices a client and wants to be paid on time without handing their books to a stranger. FREE TO START. PRO IS ONE PAYMENT. Free on every plan: three new documents a month, the Classic template, every tax rate, estimates, CSV export, and a full backup. Sending, printing, and editing what you have made is never locked. CustomInvoice Pro is a one-time purchase, not a subscription: unlimited documents, the Modern and Minimal templates, your logo and brand colour, and the aging and monthly reports. Restore purchase brings it to a new phone. Used CustomInvoice before Pro? You keep everything, free. Questions: info@customapps.us

Verdict

CustomInvoice also leads on monetization model (free vs free with in-app purchases) and iOS requirement (15.0 vs 17.0). Invoice Biz's advantage is update cadence (every 6 days vs every 3 weeks). On price, rating, ratings volume and in-app purchases there is nothing between them.
