Vorker handles the paperwork roofing firms do after hours: inspection findings, repair quotes, invoices and seasonal offers to past customers. You approve everything.

No. Every quote, invoice, email and text is prepared and then waits for you. You can read it, edit any line, reject it, or approve it and schedule it to go out later. Nothing sensitive happens on its own.
Yes. Photograph the damage and speak or type a few words, and Vorker books the findings to the property with the photos attached. The quote is then drafted from those findings and your rates, so the numbers trace back to what you actually saw up there.
Every enquiry gets a drafted reply with inspection slots from your calendar, and every inspection you photograph becomes a findings record and a quote draft. You still decide the order and press every send. The point is that the paperwork stops being the bottleneck.
You tell it once: when autumn comes, offer past customers the gutter clean and roof check. When the season arrives, the email is drafted to everyone you have worked for and held for your approval. Nothing goes out until you press.
That is exactly the size it is built for. Vorker is made for businesses of one to ten people, where the owner is on the roof all day and the admin waits until evening. There is nobody else to hand the paperwork to, which is the point.
No. You talk to Vorker the way you would text someone in the office, from the roof if you like. It works inside the tools you already have: your email, your calendar, your accounting. The quotes and invoices arrive as ordinary PDFs.
