On-Site Quote & Customer Approval: the full procedure
Turn a confirmed diagnosis into a clear, written, approved price before any work starts.
- Applies to: Plumber on a service call.
- Frequency: Every paid repair or install.
- Scope: Covers building the on-site price, presenting options, and capturing written approval. Does NOT cover pricing of code-mandated or gas work beyond the plumber’s authorization, which defers to a licensed plumber and the business safety plan.
What you need
- Job app or price book on tablet
- Flat-rate / pricing guide
- Written estimate or quote form
- Parts and materials list
- Customer signature capture (app or paper)
The procedure, step by step
- Translate the diagnosis into scope — List exactly what will be repaired or replaced based on the confirmed fault. Keep it to the work that solves the customer’s problem.
- Price from the shop’s price book — Use the standard flat-rate or pricing model the shop has set, not an improvised number. Consistent pricing protects margin and the customer relationship.
- Offer good/better/best where it applies — Where there is a repair-vs-replace or upgrade choice, present clear options with the tradeoffs. Let the customer choose with full information.
- Put the quote in writing — Itemize labor, parts, and any trip or diagnostic fee on the estimate form. No verbal-only pricing.
- Note exclusions and unknowns — State clearly what is not included and what could change if hidden conditions appear once opened up. Flag any code/gas/permit work that must go to a licensed plumber.
- Walk the customer through the quote — Explain each line and answer questions before asking for a decision. Make sure they understand price and scope.
- Capture written approval — Get a signature or recorded digital approval before touching tools. Approval ties to the specific written scope and price.
- Send a copy to the customer and office — Email or text the approved quote and sync it to the office system. Everyone works from the same number.

Frequently asked questions
Should plumbers give a written quote before starting work?
Yes. A written, itemized quote with labor, parts, and fees, approved by the customer before tools come out, prevents disputes and protects margin. State exclusions and what could change if hidden conditions appear, and route any code, permit, or gas work to a licensed plumber per your safety plan.
How do you price a plumbing repair consistently across a crew?
Use a shop price book or flat-rate guide so every plumber quotes the same job the same way instead of improvising. This is a core operational standard contractor playbooks recommend. Pricing for code-mandated or gas work that exceeds a technician’s authorization should defer to a licensed plumber and the governing code.
