## What is Mr Invoice?

Make GST-ready bills, quotations and estimates in seconds. Every feature of Mr Invoice is free, with no paywall and no hidden charges. Built for Indian shopkeepers, traders, wholesalers, freelancers and small businesses who want professional billing without paying a rupee.

FREE FOREVER, NOTHING LOCKED
Every feature is unlocked from the start. There is no paywall and no trial that quietly expires and then asks for your card. You keep making unlimited GST bills, estimates and quotations for free, for as long as you use the app. Most billing apps lock the useful parts behind a subscription. Mr Invoice does not. The app is paid for by ads, and an optional subscription turns them off. It unlocks nothing, because nothing is locked.

MADE FOR INDIAN BUSINESS
Whether you run a kirana store, a dukan, a wholesale counter, a service business or work as a freelancer, Mr Invoice fits how you already work. Create tax-ready documents that look professional and match your business.

WHAT YOU CAN DO
- Create GST invoices with correct tax, CGST, SGST and IGST split
- Add HSN and SAC codes for compliant billing
- Send estimates and quotations to win more customers
- Generate a proforma before you raise the final bill
- Issue a delivery challan for goods sent out
- Run fast POS billing at your counter
- Maintain a khata and udhar ledger of who owes you
- Track hisab, payments received and dues pending
- Manage stock and inventory with low-stock alerts
- Record expenses and see where money goes
- Raise a purchase order for your suppliers
- Print or share a clean PDF straight to WhatsApp

PROFESSIONAL TEMPLATES
Choose from a large library of ready invoice templates. Add your logo, signature and business details once, and every document you make looks polished and trustworthy.

SHARE ANYWHERE IN SECONDS
Every bill becomes a crisp PDF you can share on WhatsApp, email or print. Your customer gets a professional document instantly, and you look established even if you are just starting out.

KHATA AND UDHAR MADE SIMPLE
Keep a running ledger of credit given and payments received, just like your old bahi khata, but on your phone. Know exactly who owes you and how much, send gentle reminders, and mark payments as they come in. You never lose track of your hisab again, and you always know how much money is still to be collected from the market.

STOCK AND EXPENSES IN ONE PLACE
Track inventory as you bill, get alerts before you run out, and log your expenses so you always know your real profit. No separate accounting app needed.

GST AND TAX READY
Your invoices carry the tax details your accountant and your GST filing need. HSN and SAC codes, tax splits and totals are calculated for you, so there is nothing to compute by hand.

WHY SHOPKEEPERS CHOOSE MR INVOICE
- Every feature free, with no surprise charges
- Simple enough to use from day one
- Professional results that build customer trust
- Made in India for Indian small business needs
- Everything from billing to ledger to inventory in one app

YOUR DATA, HANDLED WITH CARE
Your business information is treated with care and used only to run the app for you. Back up your data and restore it when you switch or upgrade your phone, so your billing history is always safe. Ads are non-personalised unless you choose otherwise.

WORKS FOR EVERY KIND OF SELLER
Retailers, wholesalers, distributors, service providers, contractors, consultants, home businesses and freelancers all use Mr Invoice to bill faster and get paid sooner.

Download Mr Invoice and make your first GST invoice in under a minute.
