What a quote contains.
You send the product and the scenario. I reply with a one-page quote, and the quote is the contract.
The scenario, in one paragraph.Written the way a customer would run it, so there is no argument later about what was tested.
The product and the account I will use.Public trial, a sandbox you provide, or an invite. The tier matters: a trial that hides the feature the scenario needs is a finding, but it is a cheap one.
The dates.Start, report delivery, and for an audit, the retest window after it.
The price and the split.One number. Half to start, half on delivery of the report. No hourly billing.
What is out of scope.Named, so a second scenario becomes a second quote rather than a surprise.
If anything in the quote turns out to be wrong once I am inside the product, we fix the quote. The report does not bend to fit it.
