KVN Billing & Accounting is a GST billing app for Indian small businesses. It writes the invoice to your phone, not to somebody else's server, so it works with no signal at all.
BILLING THAT DOES NOT WAIT FOR THE NETWORK
Put the phone in aeroplane mode and raise a full GST tax invoice. The number comes from your own series, kept on the device, so it never skips and never repeats. When signal returns, everything syncs.
NINE DOCUMENT TYPES, EACH DRAWN CORRECTLY
Tax invoice, credit note, debit note, purchase bill, quotation, proforma, delivery challan, purchase order and payment receipt. A credit note is not an invoice with the heading swapped, and it is not printed that way.
GST WORKED OUT FOR YOU
CGST and SGST inside the state, IGST across it, decided from the place of supply rather than from memory. HSN and SAC codes, cess and tax-inclusive pricing all handled.
REAL DOUBLE-ENTRY ACCOUNTING
Not a summary that looks like accounts. Every invoice, payment and expense posts a real double entry. Trial balance, profit and loss and balance sheet come out on demand, and they tally.
GSTR-1 AND GSTR-3B
Built from bills you have already raised. B2B and B2C split the way the return expects, HSN totalled. Upload it yourself or send it to your accountant.
STOCK AND INVENTORY
Stock moves when the bill saves, not when you remember. Closing quantity and value per item, with a warning before something runs out.
SCAN INSTEAD OF TYPING
Photograph a supplier's bill and the app reads the name, GSTIN, bill number, date and amounts. The reading happens on the phone. The photo is never uploaded.
BARCODES
Generate codes for loose items and print stickers in five label sizes. The scanner holds a read for a full second before accepting it.
PRINT THE WAY YOU NEED
A4 for filing and email, A5 for a compact invoice, 4-inch thermal for the counter roll. Each drawn for its own paper.
SHARE IT
Send the PDF on WhatsApp or by email in two taps.
E-WAY BILL
Produces the JSON file the NIC portal accepts, built from an invoice you have already raised.
GSTIN VERIFY AND AUTO-FILL
Type the GSTIN once and the registered trade name, address and state fill themselves in.
ENCRYPTED BACKUPS
The file is encrypted on your phone before it goes anywhere. Your logo and signature travel inside it, so a restore on a new phone looks exactly as it did.
MULTI-COMPANY AND STAFF LOGINS
Two firms on one phone with nothing shared between them. Give staff a login that bills but cannot open the accounts.
NOT BUILT YET
Automatic payment reminders, web access and one-click payment links are not in the app. They are listed here so you know before you install, not after.
GETTING ACCESS
Accounts are set up by us rather than created inside the app. We configure your company, GSTIN and invoice numbering first, so your very first invoice is correct. Request access at billing.kvngroups.in.
