Comparison Table
PlanSwift
SMBConstruction takeoff and estimating software with BIM file support.
Measurement rules drive consistent quantities across drawings and model inputs without redoing takeoff logic each revision.
PlanSwift targets BIM model-based estimating teams that need repeatable quantity takeoff tied to a live plan set and managed measurement rules. The workflow supports material takeoff with layers, assemblies, and quantity schedules that estimate can export into an estimate workbook style output.
PlanSwift also supports model integration paths like IFC import and PDF sheet overlays for hybrid estimating when full model authoring varies by trade. Its distinguishing focus is estimator workflow speed through measurement rules and bid-ready quantities rather than authoring edits back into the model.

Kreo
SMBCloud takeoff and estimating software that processes BIM models and construction drawings.
AI plan recognition converts common drawing symbols into editable measured items that estimators can review and adjust.
Kreo supports PDF-based takeoff, drawing measurement, item counting, and model-based workflows within a browser interface. Users can define assemblies and formulas, assign measurements to estimate items, and export results for downstream estimating work. AI recognition reduces repetitive identification of doors, windows, walls, and other visible plan elements, while manual controls handle irregular geometry.
The main tradeoff is that recognition quality depends on drawing clarity, symbol consistency, and user review. Kreo fits contractors pricing repeated residential or commercial layouts where standardized plans create enough repetition for automated measurement to save time.
- +AI identifies common plan elements for faster count-based takeoffs
- +Supports lengths, areas, volumes, counts, and custom measurement formulas
- +Custom assemblies connect measured items with estimating calculations
- +Exports quantities for spreadsheet-based bid preparation
- –Recognition needs review when drawings use inconsistent symbols or poor scan quality
- –Complex assemblies require user-defined configuration before production use
- –Advanced model coordination coverage is narrower than dedicated BIM coordination suites
- –Automated results can require correction on irregular or highly detailed plans

Assemblies apply configured labor, material, and equipment values to measured items, while shared access supports estimator and reviewer collaboration.
The main tradeoff is configuration depth because accurate assemblies, templates, and report outputs require deliberate setup by an estimating lead. Model quantities depend on source geometry and object classification, so model cleanup can precede measurement. A commercial subcontractor can quantify a received plan set, attach scope notes, and return a priced bid without moving files between separate takeoff and estimating applications.
- +Cloud workspace supports concurrent estimator and reviewer access
- +STACK Assist AI reduces repetitive plan-symbol counting
- +Custom assemblies connect measurements to labor and material costs
- +Sheet and model workflows share one estimate record

How to Choose the Right BIM Takeoff Software
For BIM takeoff software, what separates options is how reliably quantities come out of your model and how much control you have over the measurement process. We focus on integration depth and automation where it directly affects takeoff accuracy and repeatability, not on marketing claims.
Quantity extraction accuracy
Why it matters
Quantity extraction accuracy is what determines whether your takeoff matches what the model actually contains. If extraction drifts across views or revisions, your downstream estimating work becomes guesswork.
How to check
In a demo, load a sample model and run the same quantity report from two different view states. Compare key totals (by major item categories) and check whether the result changes without any model edits.
Measurement rules control
Why it matters
Measurement rules control matters because two teams can get different quantities from the same BIM. Fine-grained rules reduce rework when your scope requires consistent cut planes, counting logic, or inclusions.
How to check
Ask the demo maker to show how they configure measurement rules for one tricky case (openings, overlaps, or partial elements). Then rerun the takeoff after toggling a rule and confirm the expected change is isolated and traceable.
Cost code mapping transparency
Why it matters
Cost code mapping transparency affects auditability of your estimate and how quickly changes flow through. When mapping is opaque, you can’t tell which quantities moved and why.
How to check
Request a walkthrough where a single model element changes and the software updates the linked cost items. Inspect whether the tool shows the mapping path from extracted quantities to cost lines in a way you can verify.
Repeatable takeoff workflows
Why it matters
Repeatable takeoff workflows reduce variation between projects and estimators. This matters when you need consistent outputs for repeated bids or iterative model updates.
How to check
Ask how they save and reuse a complete takeoff configuration (filters, rules, mappings, and output layout). Then recreate a takeoff from scratch using the saved configuration and confirm you get the same structure and totals.
Model revision comparison behavior
Why it matters
Model revision comparison behavior determines whether you can manage change without manual cleanup. If the tool can’t clearly attribute what changed, you spend time reconciling instead of estimating.
How to check
Provide two revisions of a sample model (or request a demo workflow with one). Check whether the software highlights changes at the quantity or item level and supports an orderly review process for modified totals.
Red flags
- Totals change when you switch views, without model edits.
- Rules sound configurable, but the demo can’t show an auditable reason for a quantity change.
- Mapping from quantities to cost items isn’t traceable element-by-element.
Fit by situation
- If you often receive models from different design tools, prioritize Quantity extraction accuracy.
- If your takeoffs require consistent counting logic across projects, prioritize Measurement rules control.
- If you run frequent updates to the same model, prioritize Model revision comparison behavior.
