Billing software built for traders.
Bill and buy with GST handled, keep supplier and customer accounts straight, and see your real margin on every sale. Zehen runs on your own PC and keeps working when the internet doesn’t.
Trading is a game of margins.
You make your money in the gap between what you buy for and what you sell for. When you can’t see that gap clearly, it quietly disappears.
You don’t know your real margin
A good selling rate means little if you’re not sure what the stock actually cost. Rough guesses hide the items that are quietly losing you money on every sale.
Purchases and sales live apart
Billing on the computer and purchases in a notebook means stock never matches, and you can’t line up what you owe suppliers against what customers owe you.
Cash and credit get mixed up
Some customers pay on the spot, some run an account. Without a clear ledger the credit slips through, and you end up chasing it months later.
GST and e-way bills eat time
Matching bills, working out the tax and making an e-way bill for each load by hand takes days you would rather spend trading.
It runs the whole business, not just the billing.
Zehen is one system for billing, purchases, inventory, ledgers and full double-entry accounting. Fast billing is only where it starts.
Bills in seconds with a barcode
Scan or pick an item, take cash, UPI or credit on one bill, and print in seconds. The counter keeps moving and you spend far less of your day on billing.
True profit on every bill
Stock is costed on a weighted average, so you see the real margin on each bill and each item and can spot what’s actually making you money.
Suppliers and customers in one place
A running balance and ageing for every party, payables and receivables side by side, so you always know what you owe and what you’re owed.
GST and e-way bills without the scramble
GSTR-1, GSTR-3B and HSN come ready from your own bills, and e-invoices and e-way bills print from the same screen, so filing stops eating your days.
And because it all runs on your own PC and shop LAN, it stays fast even on a day the internet is down, and your books never leave your machines.
