Sound familiar?

You're roughing in a bath remodel and the homeowner leans in: "While you're at it, could we get a hose bib out back? And move the washer box to the other wall?" Both good adds — real work that makes the house better, and work you should be paid for.

Or you open the wall and the supply is fifty-year-old galvanized that has to go before anything new ties in. Either way: drop the line items in your phone — fittings, pipe, labor — the app figures your markup and local tax, you both sign on the screen, and they get a clean PDF before the saw comes back out. Nobody's surprised at the invoice, and the job stays friendly.

Questions plumbers ask

Does it work in a crawlspace or basement with no signal?

Yes. It's 100% offline. Once it's on your phone, you can write, sign, and generate change order PDFs with zero bars.

Can I write up a surprise pipe replacement on site?

That's exactly what it's for. Write the added work as line items, the app figures markup and tax, and the customer signs on your phone before you keep going.

Is it really free?

Yes — no account, no password, no monthly fee. A one-time $29.99 Suite Pro upgrade puts your company logo on every PDF — across all three DFS apps.
