Outsource Estimating Services Outsource your estimating. Keep your own estimator.

Looking to outsource estimating services without sending your plans to whoever is free? We assign you a dedicated, AI-enabled estimator who works only on your bids, in your time zone, on your company email, in your software and your templates. One fixed monthly fee, about a third of what an in-house estimator costs once payroll tax and benefits are counted.

Why contractors outsource estimating

More bids out the door, without the hiring.

Finding and training a good estimator takes months, and the market is short of them. Outsourcing to a dedicated estimator gets you the same capacity in about a week, with one predictable monthly cost.

Capacity

Bid the jobs you pass on today

Most contractors turn down invitations because nobody has time to price them. A dedicated estimator adds bidding capacity without adding headcount or desk space.

Cost

About a third of in-house cost

No salary, payroll tax, 401(k) match, health insurance, recruiting fees or PTO coverage. One fixed monthly fee covers your estimator, QA and management.

Speed

About 7 days, not 3–5 months

Skip the job posts and interviews. Your estimator is typically on your live bids in under 7 days.

What outsourced estimating actually means

Outsourced estimating means someone outside your payroll prepares your takeoffs, pricing and bid documents. There are two very different ways to buy it. A per-project service takes a set of plans, sends back quantities and moves on to the next customer. A dedicated model, which is how we work, assigns one estimator to your company. That estimator stays on your account, learns how you price work, and works through your bid list the way an in-house estimator would.

Three kinds of companies outsource estimating most often. Subcontractors use it to price the scopes their crews self-perform, with takeoffs, labor hours and unit rates. General contractors use it for self-perform takeoffs, sub-bid leveling, scope sheets and bid coordination across every division. Suppliers use it for material takeoffs and quote support, so they can quote more jobs without adding estimators. The model is the same in each case: one estimator who learns how your company prices work.

The rest of this page covers how outsourcing compares with an in-house hire, what it costs, which parts of the bid process you can hand over, how the first week works, the trades and software we cover, and when outsourcing is the wrong call.

In-house vs outsourced

In-house estimator vs outsourced estimating.

An in-house estimator is a great asset when you can find one, afford one and keep one. Here is how the two options compare on the points that usually decide it: cost, time to start, overhead, software, coverage and scaling.

*Market figures are typical industry estimates and vary by region and role.

The salary is only part of an in-house estimator’s cost. Employer payroll tax, a 401(k) match, health insurance, paid time off, recruiting fees, a desk, hardware and software seats all sit on top of it, along with the months of bids you can’t chase while the seat is empty. A dedicated outsourced estimator puts all of that into one fixed monthly fee, and you still get what made in-house attractive in the first place: someone who knows your company, works your hours and answers to you.

Two ways to outsource

Per-project takeoffs vs a dedicated estimator.

Once you decide to outsource, the next choice is the model. Most estimating services online sell per-project takeoffs. That works for the occasional job. For a steady bid list, a dedicated estimator gives you continuity: the same person, your standards, and better numbers on every bid.

Per-project takeoff services

Pay per job, start over every time

  • Whoever is free works your plans
  • You re-explain your standards on every job
  • Takeoff quantities only, rarely a full estimate
  • Turnaround depends on their queue
Bidding Enterprise

Your own dedicated estimator

  • One estimator who works only on your bids
  • Learns your company, past bids and pricing
  • Full estimates in your software and templates
  • Reports directly to you, in your time zone
Backed by a team

QA and AI on every bid

  • AI takeoff tools speed up the first pass
  • QA and technical managers check the work
  • 140,000+ jobs estimated, 600+ estimators
  • 2026 Inc. 5000, #63 in Construction
What you can outsource to us

The whole pre-construction workload, or just the part that’s buried.

Your estimator can own a single step or run your bids end to end, from finding the work to following up after bid day. Start with whatever is slowing you down, usually takeoffs and pricing, and hand over more as you get comfortable.

Find the work

Sourcing & outreach

  • Sourcing bids. Invitations tracked and logged, and new projects surfaced from the bid boards and portals you use, matched to the work you want.
  • GC outreach. Introductions to the general contractors and owners you want to bid to, so more invitations come to you.
  • Bid follow-up. We chase the outcome after bid day, so good opportunities don’t die in an inbox.
Price the work

Takeoffs & pricing

  • Quantity takeoffs. Measured in your takeoff software, organized the way you price, and easy to review.
  • Labor hours. Realistic crews and production rates for the work you self-perform.
  • Supplier quotes. Material and sub quotes requested, chased and normalized so you compare like with like.
  • Unit-rate analysis. Your rates checked against the live market and against your own past won and lost bids, so you know where you’re high or low.
Submit the bid

Scope, RFIs & proposals

  • Scope writing and leveling. Trade-specific scope so nothing is assumed, and sub bids compared on equal footing.
  • RFIs. Questions raised early and answers tracked, with drawings and addenda kept straight.
  • Proposals. Clean proposals in your template and your voice, with inclusions, exclusions and clarifications spelled out.
Run the desk

Analysis, reporting & coordination

  • Market analysis. What’s being bid in your market, where pricing is moving, and which GCs and project types you win with.
  • Monthly reports. A monthly summary of what was bid, what was won and lost, and what’s coming up.
  • Coordination. Your estimator works with your PMs, owners and field team through your email and your meetings, like an in-house estimator.

If you need help coordinating bids rather than pricing them, see our bid coordination services: bid calendars, ITBs, sub and supplier invitations, addenda and bid forms, handled by a dedicated coordinator.

How it works

From first call to live bids in about a week.

Outsourcing your estimating shouldn’t turn into a long onboarding project. Here is the whole process, start to finish.

Step 1

A one-hour call

We review your trade, the bids you chase, your software and templates, and how you price work today. You find out on that call whether we’re a fit, and qualified contractors get 15 days of free estimating.*

Step 2

Matched to an estimator trained on your scope

We match an estimator who already knows your trade, then train them on your templates, past estimates, pricing and standards. They work on your company email, in your time zone.

Step 3

Your live bids, in your software

Your estimator starts on real bids, not test files, inside the takeoff and estimating tools you already use, with Build Intel and Dexter speeding up the first pass.

Step 4

QA review before it reaches you

Our QA and technical managers check the takeoff and pricing for gaps, outliers and missed scope. You review the final number and submit.

Step 5

Scale up or down

Add a second estimator, a bid coordinator or a full desk as your bid list grows, or scale back when it slows, on the notice terms in your agreement. If the fit isn’t right, we replace your estimator at no cost.

A straight answer

Should you outsource your estimating?

Owners and estimators ask each other this all the time, and the honest answer is that it depends on your bid volume, your margins and how much of your pricing lives in one person’s head. Here is how we’d think it through, even if the answer isn’t us.

It usually makes sense when

Estimating is the bottleneck

  • You’re turning down invitations because nobody has time to price them.
  • The owner or a PM is doing takeoffs at night instead of running jobs.
  • You’ve tried to hire an estimator and gone months without finding the right person.
  • Your bid volume swings, so a permanent hire would sit idle in slow months and drown in busy ones.
  • You want to bid a new trade, region or project type without building a department first.
  • You want a second set of eyes on your numbers but have nobody to check the estimator.
It usually doesn’t when

The volume or the role isn’t there

  • You bid a handful of jobs a year. A per-project takeoff, or doing it yourself, is cheaper.
  • Your “estimator” also runs jobs, walks sites daily and manages crews. That’s a different role.
  • You won’t spend a few hours on onboarding. A dedicated estimator learns your pricing from your past bids and your feedback; skip that and you get generic numbers.
  • You need someone physically in your office every day.

Many growing contractors sit in the middle: steady bid volume, an owner who has become the bottleneck, and no appetite for a 3–5 month search. That’s the problem a dedicated, outsourced estimator is built to solve. If you’re not sure, the 15 free days are the cheapest way to find out. Your estimator works your real bids, and you decide with real results in front of you.

Choosing a partner

Eight questions to ask any outsourced estimating service.

Estimating services look alike from the outside. These questions separate a partner who will sharpen your bids from one who sends back quantities and disappears. Ask them of us, and of anyone else you’re considering.

01 · People

Who actually works my bids?

A good answer names one person who stays on your account. A pool of whoever is free means re-explaining your standards on every job. Our answer: one dedicated estimator, exclusive to your company.

02 · Trade

Do they know my trade?

A general estimator pricing electrical or steel learns on your bids. Ask what trade experience the person assigned to you has. Our answer: every estimator is trained for the trade they estimate, across 50+ trades and scopes.

03 · Tools

Will they work in my software and templates?

If the output arrives in someone else’s format, you re-key it, and that’s where errors creep in. Our answer: your software, your templates and your cost data, across 100+ tools.

04 · Quality

Does anyone check the work?

Every estimator misses something eventually. Ask who reviews the numbers before you see them. Our answer: QA and technical managers review the work, and you review and approve the final number.

05 · Cost

Is the cost predictable?

Per-bid pricing makes your estimating cost swing with your bid volume. Our answer: one fixed monthly fee, about a third of an in-house estimator’s loaded cost.

06 · Fit

What happens if it isn’t working?

Even good estimators aren’t right for every company. Ask what the remedy is. Our answer: if the fit isn’t right, we replace your estimator at no cost.

07 · Confidentiality

How is my pricing protected?

Your unit rates and past bids are your edge. Ask how they’re handled. Our answer: your drawings, pricing and cost data are treated as confidential information under our terms and used only to do your work.

08 · Proof

Can I try it on real bids first?

Sample takeoffs on someone else’s project prove little. Ask to see the work on your own bids. Our answer: qualified contractors get 15 days of free estimating on their live bids.*

Getting the most from it

What to send your estimator in week one.

The difference between generic numbers and numbers that sound like your company is what you share at the start. The more of your history your estimator sees, the faster their estimates match the way you price.

Your history

Past bids, won and lost

  • A handful of recent bids with the final numbers you submitted
  • Which ones you won and lost, and the winning number where you know it
  • Jobs that made or lost money, so rates can be benchmarked to your actual results
Your standards

Templates and pricing rules

  • Your estimate templates, assemblies and cost database
  • Labor rates, crew makeup and the production rates you trust
  • Your standard inclusions, exclusions and clarifications
  • How you apply overhead and markup
Your pipeline

Access and go/no-go rules

  • Logins or invitations for the bid boards and plan rooms you use
  • Your preferred subs and suppliers
  • Your bid calendar, and the jobs you will and won’t chase

You stay in control of the number. Your estimator prepares the takeoff and pricing the way you’ve shown them, our QA team checks it, and you decide the final price and markup before anything goes out. Mark up the first few estimates the way you would for a new in-house estimator. That feedback is how a dedicated estimator gets sharper on every bid, and it’s the advantage a per-project service can’t give you.

Trades we estimate

If it gets bid, we estimate it.

Every estimator is trained for the trade they estimate. We cover 50+ trades and scopes for subcontractors, general contractors and suppliers. They’re organized below by CSI MasterFormat division. Pick a trade to see what a takeoff and estimate include.

Software our estimators use

Your software, your templates.

You don’t switch platforms or rebuild templates to outsource estimating. Your estimator learns your setup, works in the tools you already own, and delivers in your format, ready to drop into your bid.

Takeoff & estimating

  • Bluebeam Revu
  • PlanSwift
  • On-Screen Takeoff
  • STACK
  • Excel
  • Your own bid templates

The everyday tools for measuring plans and building the estimate. Your estimator uses your company’s setup, assemblies and cost data, not a generic library.

Trade-specific programs

  • Trimble Accubid
  • McCormick
  • ConEst IntelliBid
  • Trimble QuickPen
  • FastPIPE
  • Trimble QuickDuct
  • FastDUCT
  • AGTEK
  • Trimble Business Center
  • Carlson Takeoff
  • RebarCAD
  • aSa Rebar
  • Measure Square
  • RFMS Measure
  • Tekla model quantities

Electrical, plumbing, HVAC, site work, rebar, flooring and steel estimators are matched to the trade programs those scopes are priced in.

Bid boards & plan rooms

  • BuildingConnected
  • PlanHub
  • ConstructConnect
  • iSqFt
  • Procore Bid Management
  • Dodge
  • The Blue Book
  • Public agency portals

Where invitations arrive and plans are pulled, so sourcing bids and tracking addenda happen where your GCs already post them.

Our AI tools, included

  • Build Intel
  • Dexter

Build Intel is our AI-assisted estimating software. Dexter is our AI co-estimator: it reads your drawings and specs and answers with the sheet or section cited. AI drafts, your estimator verifies, QA signs off, and you review and submit.

AI-enabled, human-verified

AI makes an estimator faster; it doesn’t replace one. Build Intel’s AI-assisted takeoffs, learned from 140,000+ jobs estimated, get quantities started sooner and more consistently. Dexter finds what a spec section requires or where a detail lives, so questions get answered in seconds instead of a page-by-page search. Automated QC flags missing scope and outlier numbers before a bid leaves the building. Then an experienced estimator checks every count, our QA team signs off, and you make the final call.

These are common examples, not a complete list. Our estimators work in 100+ estimating and takeoff tools. See how software changed estimating.

FAQ

Outsource estimating services: common questions

What are outsourced construction estimating services?

Outsourced estimating means a team outside your company prepares your takeoffs, pricing and bid documents. With Bidding Enterprise you get a dedicated estimator who works only on your bids, in your software, templates and cost data, like an in-house estimator without the hiring, payroll and overhead.

How much does it cost to outsource estimating?

Bidding Enterprise charges one fixed monthly fee for a dedicated estimator, typically about a third of what an in-house estimator costs once salary, payroll tax, 401(k), health insurance, recruiting and overhead are counted. The exact fee depends on your trade and how much of the bid process you hand over, and we confirm it on the free assessment call. Qualified contractors can try it free for 15 days.

How is a dedicated estimator different from per-project takeoff services?

Per-project services send each job to whoever is free, so you re-explain your standards every time. A dedicated estimator learns your company, your past bids and your pricing, stays on your account, and reports directly to you.

Should I outsource my estimating?

If you're turning down bids, the owner is doing takeoffs at night, or you've spent months trying to hire, outsourcing to a dedicated estimator usually pays off. If you only bid a few jobs a year, a per-project takeoff or doing it yourself is likely cheaper. See when outsourcing makes sense, and when it doesn't.

Can ChatGPT do construction estimates?

Not on its own. General chatbots like ChatGPT can explain estimating methods, draft scope language or check arithmetic, but they don't measure your drawings, don't know your crews' production rates or current supplier pricing, and can produce confident numbers that are simply wrong. A bid you sign needs quantities taken off the actual plans and prices tied to real quotes and your own history. Our estimators use purpose-built AI instead: Build Intel speeds up takeoffs, and Dexter answers questions about the drawings and specs with the sheet or section cited. An experienced estimator checks every output, and our QA team reviews it before it reaches you.

Why do estimators make so much money?

Because good estimators are scarce and the job is hard to do well. It takes field knowledge, plan reading, math, software skills and pricing judgment, and one missed scope item can wipe out the margin on a job. Demand outruns supply: by typical industry estimates there are more than 12,000 open estimator positions across the US, and an estimator's salary runs around $100K-$120K before benefits, payroll taxes and overhead, varying by region and role. That cost is why many contractors outsource estimating to a dedicated estimator for a fixed monthly fee instead.

What are the four main types of estimating?

Most estimating references group them into four: (1) order-of-magnitude or conceptual estimates, based on the cost of similar past projects; (2) square-foot or cubic-foot estimates, a cost per unit of area or volume for early budgets; (3) assembly or systems estimates, which price complete systems such as a wall type or roof assembly; and (4) unit-price or detailed estimates, built from a full quantity takeoff with material, labor and equipment priced line by line. Accuracy and effort both rise as you move down the list. Bid-day numbers are almost always unit-price estimates, and that's the core of what our estimators produce, along with conceptual budgets when you need an early number.

Do contractors usually charge for estimates?

It depends on the market. On small residential jobs, many contractors give free estimates as a cost of winning work, while some charge a fee and credit it back if the customer signs. In commercial work, subcontractors and general contractors usually bid at their own cost, and paid estimating tends to appear as preconstruction or design-assist services. Either way, most estimating is unbilled overhead, so keeping its cost predictable matters. A fixed monthly fee for a dedicated estimator is easier to plan around than a salary plus benefits.

Who sets the final bid price and markup?

You do. Your estimator prepares the takeoff and pricing using your templates, rates and rules, our QA team checks it, and you review and approve the final number, including overhead and markup, before anything is submitted.

Is my pricing kept confidential?

Yes. Your drawings, pricing, historical cost data and templates are treated as confidential information under our terms and used only to perform your work. Your estimator is exclusive to your company, so your numbers aren't shared across other clients' bids.

Is outsourced estimating accurate?

Every estimate is prepared by an experienced estimator, sped up by AI takeoff tools, then checked by our QA and technical managers before it reaches you. You review and approve the final number.

Will the estimator work in our time zone, email and software?

Yes. Your estimator is exclusive to your company, works your hours in your time zone, uses your company email, and works in your estimating software and templates, so to your GCs and suppliers they are part of your team.

Which trades and software do you cover?

Over 50 trades and scopes, from concrete, site work and steel to drywall, flooring, MEP and full general-contractor bids, in the 100+ estimating and takeoff tools contractors already use.

How fast can we start?

The free assessment and setup take about an hour, and most clients have their estimator on live bids in under 7 days.
