Small-job quotes: what would make you switch from a spreadsheet?

I own Contractor Vision, launching here October 22. I would like feedback from handymen and small crews who quote repair or remodeling jobs. The browser sample needs no account, installation or card: https://contractor-vision-web.onrender.com/demo . Change the material price and labor hours, review the total, convert the sample estimate to an invoice and preview the PDF. Are the labor, markup and invoice controls clear? What is missing from the workflow you use today? Please use sample information rather than real customer records. The full app includes separate hourly/daily helpers, tax, deposits and extras. Three new estimates/invoices total are free; Pro is $9.99 USD/month until cancelled, with separate AI limits. This is a request for honest feedback, not positive reviews or votes.
