About this app

Stop rebuilding the same invoice in a spreadsheet every week. Invoice+ is an offline invoice maker that turns a finished job into a numbered PDF invoice in about a minute, right on your phone.

Pick a client, add your lines, hit send. The app does the math, applies your tax rate, stamps the next invoice number and puts your logo on the page. No desktop, no template file, no account to create first.

🧾 MAKE AN INVOICE IN UNDER A MINUTE
• Sequential invoice numbering handled for you — INV0001, INV0002, and on
• Line items with quantity, unit price and your unit: hour, day, sq ft, piece
• Per-line discount, and a discount on the whole invoice, percentage or fixed
• Issue date, due date and payment terms on every bill
• Subtotal, discount, tax and total recalculated as you type

💵 SALES TAX, DONE THE WAY YOU DO IT
• Four tax modes: none, on the total, tax-inclusive, or per line item
• Name the tax yourself — Sales Tax, VAT, GST, whatever your paperwork says
• Set any rate, and flip individual lines to non-taxable
• Six currencies built in: $, CA$, €, £, ¥ and CHF

📄 A PDF INVOICE THAT LOOKS LIKE A REAL BUSINESS
• Print-ready PDF invoices with your logo, business name, address, phone, email
• See the finished page inside the app before your customer does
• Email it — your mail app opens with the subject and message written
• Share the PDF through any app, or print to a connected printer
• Sending an invoice marks it as sent for you

👥 CLIENTS YOU ONLY TYPE ONCE
• Import from your phone contacts; add tags, a rating and notes
• Company, two emails, two phones, billing address, tax or ID number
• Clients with invoices are protected from deletion

📦 A PRICE LIST THAT REMEMBERS
• Save any line as a reusable item: name, description, price, unit, tax
• Drop a saved item onto a new bill instead of typing it out again

💰 KNOW WHO STILL OWES YOU
A billing app and an invoice tracker in one.
• Draft, Sent, Paid and Overdue on every invoice
• Anything past its due date flags itself overdue automatically
• One switch marks a bill paid
• Month by month: total invoiced and balance still due, on the home screen
• Search invoice numbers, clients, addresses, line items and notes

📊 REPORTS THAT FIT ON A PHONE SCREEN
• Your invoiced total climbing across the month
• Paid against unpaid, day by day
• Tax collected and net totals, any month you pick

🔒 IT WORKS WITH NO SIGNAL AT ALL
Invoices, clients and prices live on the device, so a basement or a job site is fine. No account, no subscription and no cap on how many invoices you write. Google sign-in is offered once during setup and you can skip it.

🛠️ SET UP FOR YOUR TRADE
Pick your trade at setup — plumbing, electrical, HVAC, carpentry, roofing, landscaping, painting, flooring, masonry, drywall, fencing, decking, cleaning, pest control, pressure washing, snow removal, remodeling, general contracting, handyman, consulting, photography, web design. Your logo goes on every invoice.

WHY PEOPLE KEEP THIS INVOICING APP
1. It opens and it bills. No dashboard to learn first.
2. The page looks like it came from a company, not from a phone.
3. Your clients, prices and history are already there the next time.
