Accubid vs. ConEst: how to compare them fairly.
Accubid (Trimble) and ConEst are both long-established electrical estimating platforms with labor databases, assemblies and pricing. Choosing between them comes down to your bid mix, takeoff workflow, pricing service and deployment preference. RenderDraw is not a replacement for either; it speeds the takeoff that feeds them.

Questions to ask any electrical estimating tool.
| Criterion | What to check |
|---|---|
| Takeoff speed | How are devices, fixtures and runs counted: clicked, assembled or proposed by AI? |
| Labor database | Which labor units ship with it, and how easily can you calibrate them to your history? |
| Price updates | How material pricing is updated and from which services. |
| Revisions | How addenda and change orders are compared and repriced. |
| Traceability | Can a reviewer trace any quantity to its sheet and location? |
| Deployment | Desktop, cloud or both; licensing; IT requirements. |
| Output | Bid summaries, proposals and exports to your other systems. |

From plan set to reviewed quantities.
AI-powered, human-approved. Each stage records what ran, what changed and who approved it.
Start with your bid package
Drawings, specs and addenda together: power and lighting plans, the fixture schedule, panel schedules, the one-line and the Division 26 spec sections.
AI proposes quantities
Counts, lengths and areas come back with the source sheet and location attached to every row.
Estimator review
Low-confidence items surface first. Your estimator accepts, corrects or rejects each one.
Map to your assemblies
Approved quantities map to your items, assemblies and estimating assumptions.
Price reviewed rows
Labor units, material pricing and supplier quotes apply only to rows that passed review.
Hand off with evidence
Approved quantities move on to pricing and visual CPQ with the evidence trail still attached.

The AI drafts. Your estimator decides.
Speed is easy to promise. Defensible numbers are the job, so RenderDraw keeps the estimator in control of every quantity that gets priced.
- Source on every row. Each quantity keeps its source sheet, location and reviewer decision.
- Lowest confidence first. The review queue shows the drawing tile with the detection highlighted and the extracted value.
- Uncertain items flagged, not hidden. Anything the AI can't confirm goes to the estimator rather than being guessed.
- Nothing priced before approval. Rows move on to pricing only after they are accepted.
Questions estimators ask
Accubid vs ConEst: which is better?
Neither is better for everyone. Compare on a real bid: takeoff speed, labor database fit, price updates, revisions and output.
What does ConEst estimating software cost?
ConEst quotes pricing for its products; contact the vendor for current pricing and licensing options.
Does RenderDraw replace Accubid or ConEst?
No. RenderDraw produces reviewed device, fixture and run quantities from drawings with source links, which you can carry into your estimating platform.
Can AI speed up takeoff for Accubid or ConEst users?
Yes. AI-proposed counts reviewed by the estimator reduce the time spent clicking devices before pricing in the estimating system.
