Overview
Trim-Out gives plumbers, electricians, and HVAC techs the calculators they already do by hand (voltage drop, wire size, pipe volume, tonnage), plus a quoting and invoicing tool that turns a line-item quote into a client-ready PDF the client signs with a finger, on the spot.
No account and no server of ours: quotes and invoices are saved on the phone and go out only when you send them.
Features
- Job-site calculators
- Voltage drop and wire sizing, pipe volume, and tonnage and airflow: the math a tech does on every job. A calculator, not a substitute for the code book.
- Quote to invoice, in the same visit
- Build a line-item quote from a saved rate catalog, get a client signature on the spot, then turn it into an invoice with a payment link.
- No account. Your data stays on your device
- No account, no server of ours, no analytics. Quotes, invoices and client signatures are saved on the phone that made them and reach no one until you send a PDF or text.

What it does
- Run a calculator: voltage drop and wire size, Ohm's law, load to breaker size, pipe offset, drain slope, water heater recovery, BTU, tonnage to airflow, superheat and subcooling, or round duct size. Answers update as you type.
- Build a quote from labor and material lines, with material markup and sales tax. Wire size and breaker results can go straight onto the quote as a material line.
- Your client signs on the phone to accept, and you send the quote as a PDF or as text.
- Turn the quote into a numbered invoice for the full amount or a deposit, with payment terms and your payment link printed on it. Trim-Out prints the link; it doesn't take payments.
Who it's for
Owner-operator electricians, plumbers and HVAC techs who set their own rates and send their own quotes and invoices.
Questions
Are the calculators free?
Yes, all of them, with no limit. Drafting quotes, saving them and getting a client's signature are free too.
What does Trim-Out Pro add?
Your first 5 quotes are free to send. Trim-Out Pro is a one-time purchase that unlocks unlimited quotes and invoices. Nothing else is locked.
Are the results code-compliant?
They're reference calculations. Check them against your local code.
Where are my quotes stored?
Only on your phone. There's no account and no server. Export a backup file from the help screen and restore it on any phone; restoring adds what's missing and never overwrites anything.
