It is the working notebook of a company building a voice-first back office for 1-5 person trades shops. Every post answers one practical question about the phone, the admin, or the money — with arithmetic you can re-run yourself and no filler. No trend pieces, no thought leadership. Every post belongs to one of three clusters, each with a hub page that goes deeper: starting your own shop lives at [going independent](https://therivetapp.com/going-independent), the phone-coverage money questions live at [Rivet vs. an answering service](https://therivetapp.com/vs/answering-service), and the missed-call arithmetic lives in the [missed-call cost calculator](https://therivetapp.com/tools/missed-call-cost). Start with whichever question is currently costing you sleep. ## All posts Going independent ### [How to send an invoice from the truck](https://therivetapp.com/blog/how-to-send-an-invoice-from-the-truck) Getting invoices out the same day as the job, from your phone: the options, what an invoice needs on it, and how to stop the 9pm paperwork session.

Updated July 25, 2026 ## Common questions ### Who is this blog for? Owners of 1-5 person trades shops — HVAC and plumbing are the trades our models are deepest in, with electrical and painting supported and expanding — who do their own admin from the truck. If you dispatch a ten-truck fleet with office staff, most of these posts will feel small to you, and that's by design. ### Do I need Rivet for any of this advice to work? No. The checklists, comparisons, and math are written to be useful on their own. Where Rivet fits, we say so in a clearly marked section — and Rivet itself is in early access, so we'd rather earn trust with useful posts than oversell. ### How do you keep the numbers honest? We don't publish invented market statistics or unnamed customer stories. When a post needs a number, it is either arithmetic you can re-run with your own figures — like the missed-call calculator — or an assumption stated in the open that you can adjust. ## Done reading about the back office? Hear yours out loud Forward your line, speak one job, and watch the proposals come back. Nothing ever sends without your yes.
