About this app

Still chasing payments with spreadsheets and word-processor PDFs? Invoice Flow is a professional invoice maker and billing app for freelancers, the self-employed, and small business owners — create, send, and track invoices and estimates right from your phone, even offline.

⚡ TYPE TEXT — GET AN INVOICE
Write it like a message: "Acme, design 2 days at 150, hosting 40" — and the invoice generator turns it into a ready draft with client, items, and totals. Check, tap, send. The fastest way to bill on Android.

✍️ CLIENT SIGN-OFF ON YOUR SCREEN
Hand your phone to the client — they sign right on the screen. Name, date, and place are stamped into the invoice PDF. Perfect for contractors, deliveries, and on-site work.

💸 GET PAID FASTER
Offer early-payment discounts that apply and settle automatically when the client pays inside the window. Charge automatic late fees on overdue invoices. Embed payment links and QR codes — Stripe, PayPal, bank transfer, crypto.

📄 12 PROFESSIONAL TEMPLATES
12 polished PDF invoice templates × 5 color palettes = 60+ looks to match your brand. Plus a custom template editor to design your own.

🧾 INVOICES, ESTIMATES & CONTRACTS
Create quotes and estimates, convert them to invoices in one tap, manage contracts and delivery notes — your whole document flow in one invoice app.

🌍 BUILT FOR GLOBAL BUSINESS
150+ currencies with live exchange rates. Tax presets for 55+ countries (US sales tax, EU VAT, GST and more) — see the default rate and your own override side by side and choose which is active. PDF labels auto-translate into 16 languages.

🌐 SHARE AS A WEB PAGE
Send an invoice as a clean web page with payment buttons and QR — clients open it in any browser, no app needed.

⏱️ TIME TRACKING, EXPENSES & PROJECTS
