Spreadsheets vs a real report system
Excel will hold a flow and a pressure. It will not hold the photo, the two signatures, or the letterhead the client expects.
A spreadsheet is a good working pad. It is a poor deliverable. Someone still copies the figures into a document, still chases a scan, still sends it tomorrow.
When a spreadsheet is enough
Scratch maths. A column of last year’s flows. A unit conversion you do not want to look up again. That is what the calculators are for — use them when you just need the number.
What the client still needs
Site, system, gauges, pass or fail, photos, both signatures, and a page that looks like it came from your business. Oz Fire Wizard is the report: field capture, review queue, branded PDF. The history of the site stays with you so next year is faster.
