A practical document, not accounting software
This builder is designed for fast quoting and customer presentation. Draft data stays in local browser storage; it is not sent to WaterProStack. Use Print / Save PDF and choose your browser's PDF destination to create a file.
Before sending a document, verify prices, tax treatment, licensing language, scope, exclusions, payment terms, and any consumer-contract requirements that apply where you work. This tool does not create legal or accounting advice.
Keep the margin after the quote.
