Enter each item with its quantity and rate, add the customer name and any advance received, then press Check and Share. The tool writes the whole summary as one block of text with the line totals, grand total and balance already worked out. Copy it and paste it into the chat, or use the Share button to hand it straight to WhatsApp. Nothing has to be typed twice and the arithmetic is done for you.

Put an asterisk immediately before and after the words, with no space between the asterisk and the text — for example *Grand Total: ₹29,610*. WhatsApp turns that into bold when the message is sent, and the asterisks themselves disappear. This tool already places the asterisks around the customer name, the date label and the total lines, so the summary arrives with the important numbers standing out.

For confirming what was ordered, no. A written order summary in the chat is a record both sides can scroll back to, and it settles most disputes about quantity, rate and what was already paid. It is not a tax invoice: it has no invoice number, no GSTIN and no tax breakup. If your buyer needs a tax invoice for input credit, your accounting software or accountant still has to raise one. Use the slip for confirming the deal and the invoice for the paperwork.

Each line total is quantity multiplied by rate. The grand total is the sum of those line totals. The balance due is the grand total minus the advance or token amount you have already received. If you enter an advance larger than the order value, the tool flags it as extra advance rather than showing a negative balance, so a typo does not go out to a customer as a confusing number.
