Free forever
Every feature in the app costs nothing. No subscription, and no trial that runs out.
Works offline
Billing carries on when the internet is down, because everything runs on your computer.
Your data stays with you
Customers, products and invoices are saved on your computer, not on our servers.
A clear screen for every job
These are real screens from Invoiceo 1.0.0, filled with a sample shop.
Everything a shop counter needs
From the first quotation to the final receipt, Invoiceo keeps your billing in one place.
GST-ready invoices
Add your GSTIN, HSN/SAC codes and tax rates. Bills show CGST and SGST, or IGST for sales to another state, under titles such as Tax Invoice or Bill of Supply.
Quotations, payments and receipts
Send a quotation and turn it into an invoice in one step. Record full or part payments, print payment receipts and see what each customer still owes.
Print on the printer you have
Six invoice designs for A4, A5 and A6 paper, plus a receipt layout for 58 mm and 80 mm thermal printers. Receipts can print by themselves after every sale (Modern layout).
Tamil and seven other languages
Use the app in English, Tamil, Hindi, Nepali, French, Spanish, Chinese or Tibetan (partly translated). Tamil product and customer names print correctly on PDFs and thermal receipts.
Customers and products
Keep your customer list and product catalogue with prices, units, stock levels, batch numbers and expiry dates. Add items to a bill with a barcode scanner.
Reports that answer real questions
Revenue, tax, invoice status, money still to collect, daily sales and stock value. Print a statement for any customer and export your lists to CSV or PDF.
UPI QR and bank details
Print your UPI QR code and bank account on the invoice, so customers can pay the moment they receive it.
Several businesses, several users
Run more than one company from the same computer, each with its own data. Give staff their own login with admin or user rights.
Backup and restore
Back up a company in one click and restore it whenever you need to, including from a backup file you copied from another computer.
