Field Quoting Glossary and FAQ Hub for Trade Contractors
Reviewed for 2026, updated September 8, 2026.
Plain-language definitions of the terms that show up in estimating, pricing, and quoting, plus straight answers to the questions contractors ask most.
- Acceptance
- The customer's formal agreement to a quote, usually a signature, an electronic approval, or a written confirmation. Acceptance turns the quote into an agreement to do the described work at the stated price and terms.
- Allowance
- A placeholder dollar amount in a quote for items the customer has not yet selected, such as fixtures or tile. If the customer's final choice costs more or less than the allowance, the difference is adjusted on the invoice.
- Assembly
- A bundled price book item that combines the labor, materials, and incidentals for a common task into one line, such as replacing a standard water heater. Assemblies speed up quoting because the components do not have to be added individually each time.
- Bid
- A formal offer to perform a defined scope of work for a stated price, most often used in commercial and public projects with a competitive selection process. In residential work the terms bid, quote, and estimate are frequently used interchangeably, though a bid usually implies a firm price.
- Change order
- A written, approved modification to the original scope or price after the quote is accepted, typically triggered by a hidden condition or a customer request. A good change order documents the reason, the added or removed work, and the price impact before the work is performed.
- Contingency
- An amount added to a quote to cover unknowns that are likely but not yet identified, such as concealed damage in an older home. It can be shown as a separate line or built into the pricing, and it should be sized to the actual risk of the job rather than applied by habit.
- Cost-plus pricing
- A pricing arrangement where the customer pays the contractor's actual costs plus an agreed percentage or fee. It shifts the risk of overruns to the customer and is common on projects where the scope cannot be fully defined up front.
- Deposit
- A partial payment collected at acceptance, before work begins, that commits the customer and covers early material purchases. Some states limit the deposit a home improvement contractor may collect, so the allowed amount should be checked against local rules.
- Direct costs
- The costs that can be tied to a specific job: labor hours, materials, subcontractors, equipment rental, permits, and disposal. Direct costs are the starting point of a profitable price, before overhead and margin are added.
- Estimate
- An approximate price for a job based on the information available at the time, with the understanding that the final amount may vary. In everyday trade use an estimate is often treated as a quote, so the document itself should state whether the price is firm or approximate.
- Exclusions
- The section of a quote that lists work, materials, or conditions that are specifically not included in the price. Clear exclusions prevent disputes by setting the boundary of the scope before the customer accepts.
- Fixed-price quote
- A quote where the total is firm for the stated scope regardless of the actual hours or materials used. The contractor carries the risk of overruns and keeps the benefit of efficiency, which is why the scope and exclusions must be precise.
- Flat-rate pricing
- A pricing method where each task has a set price from a book, presented to the customer before work begins, instead of billing by the hour. It is common in residential service trades because customers know the total up front and technicians quote consistently.
- Fully loaded labor rate
- The true hourly cost of a worker, including wages, payroll taxes, insurance, benefits, paid time off, and unbillable hours, rather than the wage alone. Quoting from the bare wage is one of the most common ways contractors underprice labor.
- Good-better-best options
- A presentation style that offers the customer three tiers for the same job, typically a basic fix, a recommended solution, and a premium option. It gives the customer control over the decision and often raises the average job value without pressure.
- Gross margin
- The portion of the selling price left after direct costs, expressed as a percentage of the price. Margin is different from markup: a 50 percent markup on cost produces a gross margin of about 33 percent of the selling price, and confusing the two leads to underpricing.
- Line item
- A single entry on a quote representing one task, material, or option with its own description, quantity, unit, and price. Line items let the customer see the structure of the total and make it easy to add or remove parts of the scope.
- Markup
- The percentage added on top of cost to arrive at a selling price. Because markup is calculated on cost rather than price, it always looks like a larger number than the margin it produces.
- Mobilization
- The cost of getting people, equipment, and materials to the site and set up before productive work begins, including travel time and staging. It is frequently forgotten on quotes and is a common source of margin loss on small or distant jobs.
- Overhead
- The ongoing costs of running the business that are not tied to any single job, such as vehicles, insurance, tools, software, office expenses, and the owner's time spent quoting and managing. Overhead must be recovered across all jobs through pricing or it comes out of profit.
- Price book
- A maintained list of the tasks, assemblies, and materials a contractor sells, each with a unit, a cost, and a selling price. It is the foundation of fast, consistent quoting and should be reviewed regularly as wages and material costs change.
- Progress payment
- A scheduled partial payment on a larger job tied to a milestone, such as completion of rough-in or delivery of materials. Progress payments keep the contractor's cash flow healthy and should be spelled out on the quote before acceptance.
- Quote
- A document offering to perform a described scope of work for a stated price, valid for a set period. In the trades a quote usually implies a firm price for the stated scope, which is why it should include exclusions, terms, and an expiration date.
- Scope of work
- The written description of exactly what will be done, where, with what materials, and to what standard. A clear scope is the single most effective protection against disputes and unpaid extras.
- Takeoff
- The process of measuring and counting the quantities of materials and labor a job requires, taken from a site visit, drawings, or photos. Accurate takeoffs feed the price book quantities and are where most estimating error originates.
- Time and materials
- A billing arrangement where the customer pays for actual hours worked at an agreed rate plus materials at an agreed markup, rather than a fixed price. It suits diagnostic or open-ended work but gives the customer less certainty about the final cost.
- Unit price
- The price for one unit of a measurable item, such as per square foot of roofing, per linear foot of fence, or per fixture installed. Unit pricing makes quotes scale cleanly with quantity and is easy for customers to verify.
- Walkthrough
- The on-site visit where the contractor inspects the job, measures, photographs, and discusses the customer's expectations before pricing. A thorough walkthrough is the best defense against surprises and the natural moment to quote on site.
- Win rate
- The share of quotes sent that are accepted, sometimes called the conversion or close rate. Tracking it, even roughly, tells a contractor whether problems are coming from pricing, presentation, speed, or follow-up.
Questions people ask
What is the difference between a quote, an estimate, and a bid?
In strict use, a quote is a firm price for a defined scope, an estimate is an approximate price that may change, and a bid is a formal competitive offer, usually on commercial or public work. In residential trades the words are used loosely, so the document itself should say clearly whether the price is firm and for how long. What matters is that the customer and the contractor share the same understanding before work begins.
How long should a quote be valid?
Thirty days is a common default for residential work, with shorter windows when material prices are volatile or the schedule is filling quickly. Whatever you choose, print the expiration date on the quote. It protects you against cost changes and gives the customer a gentle reason to decide.
Should I charge for estimates?
It depends on the trade and the market. Free estimates are the norm for many residential services and are effectively a marketing cost recovered through overhead. Charging a fee, often credited against the job if the customer proceeds, makes sense for diagnostic work, complex projects, or long drives where unpaid visits are a real drain. Either way, be clear about it before you arrive.
How do I price a job when I do not know what is behind the wall?
Quote the work you can see at a firm price, state plainly what you could not inspect, and describe how hidden conditions will be handled, usually through a priced change order approved before the extra work starts. Some contractors add a contingency line for likely unknowns. Photographs of the visible conditions on the quote make later conversations far easier.
What is a reasonable markup for materials?
There is no single correct number because it depends on your overhead, your trade, and what you provide beyond the part itself, such as sourcing, warranty handling, and delivery. The honest approach is to work backward from the margin your business needs to cover overhead and earn a profit, then apply a markup that produces it. Remember that a markup percentage is always larger than the margin percentage it yields.
Is it better to quote on site or send the quote later?
On site is better for most routine residential work because the details are fresh, the customer is engaged, and you avoid the delay that loses jobs to faster competitors. Larger or unusual projects can justify a day of thought and a supplier call. The practical rule is to quote on site whenever your price book covers the work, and to set a clear delivery expectation when it does not.
How many photos should a quote include?
Enough to show every condition you are charging to fix, typically one wide shot for context and one close-up per issue. Attach each photo to the line item it supports rather than adding a gallery at the end. More is not always better; a few clear, relevant photos do more than dozens of unlabeled ones.
How do I follow up on a quote without annoying the customer?
Add something useful each time: an answer to a likely question, a scheduling opening, a clarification about what is included, or a reminder of the expiration date. A short first touch after a couple of days, a second about a week later, and a polite close-out after that is a reasonable cadence. Silence is not always a no, and one good follow-up often revives a job.
Should I show the customer my labor and material breakdown?
Itemize at the level of tasks and major materials so the customer understands what they are paying for, but avoid listing every fitting and every hour, which invites haggling and rarely helps. Most customers want to see structure and options, not an audit. Keep descriptions in plain language written for a homeowner.
What should I do when a customer says my quote is too high?
Ask what they are comparing it to, then walk through the scope differences, because a lower competing number is often for less work or thinner materials. Offer a good-better-best set of options if you can remove scope honestly. Do not cut price without cutting scope; that trains the customer and erodes the margin your business runs on.
How do I know if my prices are actually profitable?
Track actual hours and materials against what you quoted on a sample of jobs, and compare the result to the overhead and profit your business needs each month. If jobs consistently take longer than quoted, or your bank balance does not reflect your sales, the price book is optimistic somewhere. Fixing the few chronically underpriced items usually has the biggest effect.
Do I need a signed contract in addition to an accepted quote?
For many small residential jobs, a quote that includes scope, price, terms, exclusions, and a signature or electronic acceptance serves as the agreement. Larger projects, and home improvement work in some states, are subject to specific contract requirements about content, cancellation rights, and deposits. Check your state's rules and, when in doubt, use a written contract that references the quote.
What is the fastest way to build a price book from scratch?
Start with the twenty to forty jobs that make up most of your revenue, write down the labor hours and materials for each, apply your fully loaded labor rate and material markup, and set a selling price with the margin you need. Do not try to be complete on day one. Add items as you quote them and review the whole list on a regular schedule.
