Invoice AI is the fastest way to bill from your phone. Build the invoice in three steps — client, items, total — turn it into a PDF and send it by WhatsApp or email before you leave the job. No templates, no laptop, no waiting until you're back at the office. INVOICES • Three-step flow: client, items, total • Taxes and discounts per line or on the total • PDF with your details, your logo and your numbering • Full-screen customer signature • Duplicate a past invoice and change only what moved • Void without deleting: the document stays in your history PAYMENTS • Record partial payments and see the outstanding balance instantly • Save how you were paid: bank transfer, PayPal, Zelle, CashApp, Venmo • Send a payment link by WhatsApp, SMS or email, with the amount built in • The app remembers the methods you use with each client ESTIMATES • The same screen you already know, with its own numbering • Statuses: draft, sent, accepted, declined, expired and invoiced • Turn an accepted estimate into an invoice without retyping anything • Optional expiry date, so it lapses on its own CLIENTS AND PRODUCTS • Your client list with their details and payment terms • A catalog of products and services with price, tax and discount • Search by name or code, no menus • Add a client or a product without leaving the invoice DASHBOARD AND REPORTS • What you're owed and what's overdue, right on the first screen • Sales and estimates for the period you pick • Charted reports on invoicing, clients, products and estimates • Export any of them to PDF or CSV for your spreadsheet YOUR ACCOUNT, YOUR DATA • Sign in and get your data back on a new phone • Automatic cloud backup • Choose which backup to restore, not just the latest one WORKS OFFLINE Your data lives on your phone. Bill on site, at the market or at your client's door with no signal, and the PDF still comes out. YOUR LANGUAGE, YOUR LOOK English, Spanish and Portuguese, light or dark theme. The app follows your phone if you'd rather not choose. BUILT FOR ONE HAND Big targets, buttons where your thumb lands, not one extra step. We designed it watching how people actually bill: standing up, in a hurry, with the client waiting. Invoice AI is for people who bill and collect themselves — trades, retail, home services, distribution and counter sales.
