Send an invoice from your phone and always know who still owes you: every unpaid bill, how many days late, and the client one tap away on WhatsApp. No account needed.
Send an invoice from your phone, and always know who still owes you.
Build a professional invoice in a minute and send the PDF on WhatsApp or email. The dashboard ranks every unpaid bill by amount and shows how many days late it is, and each client is one tap away on WhatsApp, phone or email. Record full or partial payments and see what's left until the bill is paid. Add a tax rate and the invoice is titled Tax Invoice, with the VAT shown on every line.
The Smart Billing is the all-in-one invoicing, billing, and expense tracking app designed for freelancers, small businesses, and entrepreneurs.
Whether you're sending invoices to clients, tracking your monthly expenses, or reviewing your revenue at a glance — The Smart Billing puts everything you need in one beautifully designed app.

YOUR DATA STAYS YOURS
The Smart Billing is built with your privacy in mind. No account. Works offline. Your data stays on your device and in your own iCloud. The app shares limited usage information in fixed categories, such as which features you use — never client names, invoices, amounts or anything you type — and you can switch it off in Settings → Privacy. AI features use Apple Intelligence only — on your device or on Apple's Private Cloud Compute, where nothing is stored. No third-party AI is ever involved.
WIDGETS
See your monthly revenue, unpaid invoices, and overdue bills right from your home screen — without opening the app. Available in small, medium, large, and a new extra-large iPad board.

Very easy to use

Perfect for a freelancer. My only request would be for a vendor list as well and maybe seperate customers from personal contacts. Love this program otherwise.

Fixes in this update:
• Dates are always in the Gregorian calendar, in the app and on invoices, receipts and quotations. Before, a device set to Saudi Arabia could show them in the Hijri calendar.
• A VAT rate typed with a comma (5,5) or Arabic digits is kept. Before, it could remove the VAT.
• A new device no longer adds an extra USD account while iCloud syncs; extra copies are cleaned up.
• Record Payment starts empty and uses your region's decimal mark. Pay Full Amount fills in what's due.
• CSV import and PDF exports are more reliable.
Smart Billing 5.1 is our biggest update yet.
• Every bill on its own screen: the invoice a tap away, and a timeline of everything that happened: when it was sent and how, each payment and its receipt.
• Send in two taps: the invoice or any receipt by Mail, WhatsApp or Messages. An overdue bill goes out as a friendly reminder.
• Record a payment the way it was paid: cash, card, transfer or cheque, on the day it came in. Anything extra stays as the client's credit.
• A new Dashboard: your month in 3D, paid and due, a dial to look back, and what needs stock.
• Reports rebuilt in 3D. Tap a column to open its bills, or a month's profit to see exactly what made it.
• Over 450 new 3D item icons, sorted by trade. The icons you picked switch over by themselves, and a new item picks one from its name.
• Subscribers can move to Pro or to a yearly plan from the subscription screen.
• Dates and numbers follow your region, and invoices are named in your language.
