Takeoff
Counts and measures quantities from drawings or site data: devices, luminaires, feeders, conduit lengths and other components. The output is quantities, not automatically a complete price.

An electrical contractor pricing a service-panel replacement may need a customer-ready quote in minutes. A commercial estimator pricing hundreds of circuits from construction drawings needs a fundamentally different takeoff and labor workflow. These tools are not interchangeable.
CORE CONCEPTS
Estimate, bid, takeoff and job costing explained
Estimate
Assigns material, labor, equipment, subcontract, overhead and contingency assumptions to the planned work. Estimating methods may use assemblies, labor units or unit pricing.
Bid or proposal
Turns an approved estimate into an offer with exclusions, scope, alternates, payment terms and validity dates. A professional bid is not only a spreadsheet total.
Job costing
Tracks committed and actual labor and purchases after award. Compare actual costs against the estimate and approved change orders to protect projected margin.
Ask vendors to demonstrate the entire sequence: drawing revision → takeoff adjustment → estimate revision → approved quote → change order → job-cost report.
WORKFLOW FIRST
How to choose the right estimating approach
Residential service and troubleshooting
Flat-rate tasks and clear labor/material line items can be more important than plan takeoff. Choose a tool that sends a usable quote, obtains approval and transitions smoothly into the scheduled job.
Renovations and installation jobs
You may need repeated labor assemblies, custom material lists, alternates, change orders and multiple approval steps. Verify how revisions change the original estimate.
Commercial plan-and-spec work
Prioritize drawing takeoff, takeoff revisions, electrical assemblies, labor unit adjustments, vendor quote comparison and bid leveling. Validate accuracy using one of your own drawings.
Project cost control
Check whether the estimate creates budget categories and whether invoices, committed costs and timesheets appear in the same report. Otherwise, understand the required integration.
TOOLS TO SHORTLIST
Products to evaluate and their boundaries
Crewigo may earn a commission when you use these links.
Contractor ForemanEstimate to project
Contractor Foreman can be evaluated for construction estimate, change order and job-cost workflows. It fits the project administration side of the problem.
Check before buying: Do not assume that specialist electrical takeoff, labor-unit databases or supplier price feeds are included.
JobberService quotations
Jobber documents client-facing quotes that convert to work and invoicing. Useful where the job starts from a service request rather than a drawing package.
Check before buying: Test material complexity, assembly reuse and costing detail before using it for major electrical bids.
Housecall ProService estimates
Housecall Pro is appropriate to evaluate for operational quoting tied to dispatch and field jobs.
Check before buying: Ask for a demonstration with multiple estimate options, approval requirements and revised material prices.
ServiceTitanTrade pricebook
ServiceTitan belongs on a shortlist where pricebook-driven service estimates and complex trade dispatch need to work together.
Check before buying: Request plan-specific demonstrations; validate quote assembly, permissions and the complete accounting flow.
Specialist alternative: Conest IntelliBid ↗ offers electrical estimating and material/labor libraries according to its product documentation. Crewigo does not currently have a dedicated IntelliBid review or commercial redirect. Evaluate it directly for detailed electrical bids.
CHOOSING THE CORRECT CATEGORY
Service quoting is different from commercial drawing takeoff
| Question | Residential service quote | Drawing-based commercial bid |
|---|---|---|
| Starting information | Customer request, site visit and job description | Drawing register, specifications and addenda |
| Main estimate inputs | Labor hours, parts, travel and approval | Takeoff quantities, assemblies, labor factors and supplier bids |
| Critical change | Customer requests another device or visit | Revised drawing changes measured quantities and scope |
| Must-have output | Readable customer quote and approval status | Version-controlled bid, quantities, alternates and exclusions |

ILLUSTRATIVE CALCULATOR
Electrical estimate worksheet
This free calculator illustrates how assumptions affect a simple quote. It is not a drawing takeoff tool or a substitute for measuring a job. All figures are editable and remain in your browser.
Estimated cost (incl. overhead)—
Illustrative quoted price—
Gross margin on quote—
Quote needed for target margin—
Exports your input assumptions and calculated totals; no data is uploaded.
Formula: direct cost = hours × labor cost + materials + other; estimated cost = direct cost × (1 + overhead%); quote = estimated cost × (1 + markup%). Sales tax, contingency, bond costs and other scope-specific items are not included.
ESTIMATING MATH
Markup is not gross margin
If total estimated cost is $1,000 and you add 20% markup, the quote is $1,200. The estimated gross profit is $200; gross margin is 16.7% ($200 ÷ $1,200), not 20%. To target a 20% gross margin on a known $1,000 cost, the price would instead be $1,250 (cost ÷ 0.80).
Actual profit depends on accurate quantities, scope, field productivity, supplier changes, rework, overhead allocation and collections. A pricing calculator cannot establish whether the underlying estimate is complete.
QUESTIONS TO ASK
Demo checklist for electrical estimators
- Import an actual drawing and count devices, fixtures and conduit—not a vendor-supplied sample only.
- Change a drawing revision and verify how changed quantities are highlighted and priced.
- Edit labor difficulty, crew rate and work conditions without corrupting the underlying assemblies.
- Compare supplier quotations, freight and substitutions, then generate a traceable bid version.
- Create one alternate and one change order; confirm the original bid stays auditable.
- Transfer the accepted estimate into the project budget and compare it with actual purchases and time entries.
- Export a customer-ready proposal and show how the accounting process handles sales tax and progress billing.
For a broader electrical contractor management comparison, also evaluate dispatch, field documentation and invoicing. Those are related but separate decisions.
ESTIMATING FAQ
Frequently asked questions
Does estimating software automatically produce an accurate electrical bid?
No. Accuracy depends on scope, quantities, assemblies, supplier quotes, labor productivity, exclusions and estimator review. Automation can speed up the workflow but cannot remove professional judgment.
What is the difference between electrical estimating and takeoff software?
Takeoff extracts and organizes quantities from drawings. Estimating turns those quantities and other costs into a priced scope. Some specialist products combine the two.
Can Jobber or Housecall Pro replace specialist electrical estimating software?
They may cover many routine service quotes. For complex plan-and-spec bidding, request a demonstration of drawing takeoff, labor databases and bid revisions before deciding.
Why do labor units matter?
A material count does not tell you actual install hours. Electrical estimating must account for installation conditions, crews, access and productivity assumptions.
How do I compare software prices?
Include seats, onboarding, training, takeoff modules, data subscriptions, supplier feeds and support. A low software fee can be outweighed by manual labor or missing integrations.
Is markup the same as gross margin?
No. Markup measures profit as a share of cost; margin measures profit as a share of sales price. A 20% markup yields about 16.7% gross margin, before unexpected costs.

Worked example · estimating math
From measured quantities to a defensible electrical estimate
This simplified, fictional example illustrates the calculation steps, not market prices or a recommended bid. Replace every assumption with your own supplier quotes, labor rates and site conditions.
| Estimate input | Illustrative assumption | Extended cost |
|---|---|---|
| 12 devices | 12 × $18 materials | $216 |
| 80 m cable | 80 × $2.50 materials | $200 |
| Installation labor | 14 hours × $55 burdened labor cost | $770 |
| Material waste allowance | 5% × $416 materials | $20.80 |
| Illustrative direct cost | Materials + waste + labor | $1,206.80 |
Margin check: at a target 30% gross margin, price = $1,206.80 ÷ (1 − 0.30) = $1,724.00, before any additional overhead or scope-specific charges not already included. A 30% markup is not a 30% gross margin.
Revision test: what happens when the drawings change?
Add two devices and 10 m of cable. A useful estimating tool should show the delta separately, retain the previous revision, update labor assumptions and identify which bid alternates changed. Ask each vendor to reproduce this process from the same drawing set.

Estimator verification workflow
How to test electrical estimating software with a revised drawing set
Run a controlled comparison using your own small bid package. Each vendor should price the same scope, apply the same labor assumptions and demonstrate the same drawing revision before you compare speed or total cost.
| Step | Evidence to request | Failure to watch for |
|---|---|---|
| 1. Baseline takeoff | Count fixtures, devices and measured conduit lengths against a fixed drawing revision. | Unexplained quantities or silent rounding |
| 2. Electrical assemblies | Show how materials, labor units, waste factors and work conditions combine into a cost. | Manual edits without a traceable estimate basis |
| 3. Drawing revision | Introduce a revised sheet and list all added, removed and changed quantities. | Double-counting unchanged items |
| 4. Supplier updates | Replace one supplier quote and preserve the original pricing reference. | Prices updated without audit history |
| 5. Bid and alternates | Generate base scope, exclusions, optional work and an approval-ready proposal. | Alternates unintentionally included in the base price |
| 6. Project handoff | Show whether the accepted bid transfers into a budget and actual-cost tracking. | Rekeying or broken cost-code mapping |
Compare bids using equivalent cost boundaries
Keep material, labor, equipment, subcontractor, overhead, contingency, and commercial allowances separate. A lower subscription price is not comparable if the other option includes a takeoff module, supplier-price feed or labor database that must be purchased separately.
Service estimating
Prioritize reusable service items, customer approvals and a reliable quote-to-job handoff. See electrical quoting software.
Commercial estimating
Prioritize drawing change tracking, electrical labor assemblies, bid alternatives and exportable quantities. See commercial electrical estimating.
