When more than one person sells, "who sold this" is a question the bill should answer, not a conversation at month end.
A shop with three people on the floor, or a business with field staff, has a measurement problem: turnover is known and who produced it is not. Incentives get paid on impressions, and the person quietly doing the most rarely gets the credit.
Recording the salesperson on the bill makes it a fact. It also makes the harder question answerable — not just who sold the most, but who sold at the best margin, which is rarely the same person.
The same list attendance and payroll use.
On the bill, as it is raised.
What each brought in over the period.
Volume and profit are different questions.
The paperwork either side of the bill: quotations and orders before it, returns and notes after it, on both the selling and the buying side. Each document carries over to the next, so an accepted quote becomes an order or an invoice without being typed again.
Trades that quote before they deliver live in this area — the quote goes out, the order confirms it, the challan moves the goods, and the invoice closes it.
The people it attributes to and the leads behind the sales.
Your staff, from the same employee list attendance and payroll use.
It gives you the recorded basis — what each person sold — rather than an impression of who was busy.
Bill-wise profit with the salesperson on the bill answers it, which is usually the more interesting question.
Turnover is easy to measure. Attribution is what changes behaviour.
