Introduction
A bill of materials, usually shortened to BOM, is the itemised list of everything a project needs, with quantity, size, specification and cost against each line. In manufacturing that list comes out of a product design and stays stable for years. In construction it is assembled from a drawing set by a person, changes with every addendum, and has to survive substitutions, back orders and field changes once the job starts.
That difference explains why most software marketed as bill of materials software is useless to a contractor. The established tools in the category were built for manufacturers managing multi-level assemblies of parts with fixed numbers. A contractor needs something that starts from a drawing, prices against current supplier rates, and stays connected to what actually gets bought and installed.
So the honest way to read this category is as a chain rather than a product type. The material list starts as a takeoff, becomes an estimate, turns into a purchase order, and ends up in job costing. Different tools own different stages, and almost nobody owns all four. This list follows that chain from the start.
Top 10 Bill Of Materials Software For Construction
1. The Takeoff AI
The Takeoff AI is the strongest tool on this list because it produces the material list rather than storing one. Every other option here manages, prices or tracks a bill of materials that somebody already built. This one builds it.
The engine reads a bid package and derives the quantities, covering mechanical, piping, structural, electrical and civil and concrete scope, including scanned and legacy sets with no three-dimensional model required. Items come off the schedules where schedules exist, meaning line lists, valve counts, instrument counts and equipment counts, and bulk items such as fittings, welds, supports and gaskets get derived from line length and specification using ASME B31.3 and B16.5, the American Society of Mechanical Engineers standards for process piping and flanged fittings. The output is a complete material take-off ready for material and labor pricing.
Traceability is what makes that list usable downstream. Click any line and you land on the exact element that produced it, along with the rule behind it, so a purchasing agent questioning a quantity gets an answer in seconds instead of a re-count. A bill of materials nobody can audit is a bill of materials people quietly work around. See How The Takeoff AI Works.
2. PlanSwift
PlanSwift is the desktop measuring tool a large share of estimators trained on, and for many contractors it is where the material list starts. You measure on screen, assign assemblies you have built yourself, and export quantities to Excel or an estimating package. Its flexibility across trades is genuine, since one tool covers several scopes. The cost is that it knows nothing about your materials until you teach it, so the assemblies, waste factors and specification logic are setup work your estimators perform. It runs on Windows only, with no browser or Mac version, and reviewers report stability problems on large plan sets.
3. Autodesk Construction Cloud
Autodesk Construction Cloud is where model-based material lists belong. Quantities come out of the building information model geometry rather than from measurement, which removes an entire translation step and keeps the list current as the design updates. One thing to check if you are still shopping by the old name: BIM 360 is now legacy, no longer receives new features, several of its modules have already retired, and Autodesk directs new projects to Construction Cloud. The catch is input quality, since model-derived quantities are only as good as the model, and on renovation work delivered as scanned documents there is no model at all.
4. Kojo
Kojo is the procurement half of the chain and the most construction-specific tool in this list after the takeoff engines. It takes a material list into sourcing, quoting, purchase orders, deliveries and inventory, connecting the field, the office, the warehouse, accounting and vendors, with access to a large supplier network for price and availability comparison. Trade and self-perform contractors are its audience, and it integrates with Autodesk Construction Cloud among others. It does not produce quantities, so it assumes an accurate list arrives from somewhere else, and its value is proportional to how much material you buy.
5. Procore
Procore matters here because the material list has to connect to the budget and the commitments. Keeping quantities, purchase orders and cost reports in the same system removes the reconciliation work that separate tools create, and its estimating module covers two-dimensional and three-dimensional takeoff built around commercial building drawings. The constraint is the purchase shape, since Procore is sold as a platform for the whole business rather than as material management, so buying it to handle a bill of materials means buying considerably more than that.
6. Sage 300 Construction And Real Estate
Sage 300 CRE is the most widely installed construction accounting system in the American market, and its role in this chain is the final one, where material cost lands against job cost codes. Purchase orders, subcontract commitments, billing formats and compliance reporting are thorough, and your accountant and bonding company both already know it. It is the oldest architecture on this list, the user experience reflects that, and takeoff typically comes from a partner tool rather than from Sage itself.
7. Viewpoint Vista
Vista, part of Trimble, is the enterprise option for contractors with heavy self-performed labor and equipment fleets, covering accounting, payroll, equipment, procurement and project management in one system. Its purchasing and inventory depth suits mechanical, electrical and heavy civil contractors who warehouse material across multiple jobs. It is a substantial implementation with a matching budget and timeline, and for a company running a handful of projects it is more system than the work requires.
8. OpenBOM
OpenBOM is the pure bill of materials tool on this list, built for engineering and manufacturing rather than for construction. It handles multi-level assemblies, revision control, vendor catalogs and real-time collaboration on part lists with genuine depth. Construction contractors who fabricate, meaning modular builders, skid assemblers and shops producing repeatable units, are the ones who get value from it. For a contractor working from architectural or process drawings it is oriented around a product structure your work does not have, so the fit is narrow.
9. Buildertrend
Buildertrend covers the material list as part of a residential builder's operating system, alongside scheduling, client communication, selections, change orders and financial tracking, with supplier price integration feeding quotes. For a homebuilder or remodeler that combination beats a specialist tool, and the client portal is the best in its category. It absorbed CoConstruct, which is worth knowing since CoConstruct still appears on many comparison lists despite being folded into this product. For commercial or industrial work the material handling is too light.
10. Smartsheet
Smartsheet belongs on this list because it is what a large number of contractors actually use, which is a structured spreadsheet with collaboration, approvals and automation on top. For a small contractor or a one-off project it handles a material list at almost no learning cost, and it connects to most systems through integrations. What it lacks is any construction knowledge at all, meaning no assemblies, no waste factors, no supplier pricing and no specification logic, so every rule lives in a formula someone wrote and nobody else fully understands.
Comparison Of Features
Core Functionality
The ten split into four groups. Generation covers The Takeoff AI and PlanSwift, which create the list from a drawing set. Model-based extraction is Autodesk Construction Cloud, pulling it from geometry. Procurement and control covers Kojo, Vista and Sage, which turn the list into orders and track the money. And general-purpose tools, meaning OpenBOM and Smartsheet, manage a list somebody else produced.
Most contractors need one tool from the first or second group and one from the third. The common mistake is buying two from the same group and leaving a gap at the front.
Customer Support
Two things predict support quality better than a service level agreement. Whether the vendor is construction-specific, since generalist tools staff support with people who do not know what a spool or a submittal is, and whether implementation includes data conversion, since that is where most rollouts stall.
Benefits Of Using Bill Of Materials Software
Better Project Management
A reliable material list is what makes procurement schedulable. Long-lead items get identified while there is still time to order them, and the difference between knowing in week one and finding out in week nine is usually the difference between a sequenced job and a delayed one.
Collaboration Across Roles
The estimator, the project manager, the purchasing agent and the foreman all work from the same list when it is in a shared system. Where the list lives in one person's spreadsheet, every question about it becomes a request to that person, and the list stops being accurate the moment they get busy.
Improved Cost Estimation
Material waste, over-ordering and emergency purchases at retail prices are the quiet margin losses on most jobs. A list built from the drawings with proper waste factors, rather than rounded up from memory, cuts all three, and the accuracy compounds because actual usage feeds back into the next estimate.

Integration With Other Software
Construction Estimating Software
The quantity list and the priced estimate are different documents and the handoff between them is where detail gets lost. Check that line items carry their specification, size and cost code across rather than collapsing into summary rows, because a summarised estimate cannot be purchased against.
Construction Financial Management Software
The material list has to reach job costing with its cost codes intact, so a project manager can compare committed cost to budget by code rather than in total. This is the single integration worth testing properly during a trial, since vendors describe it in similar language regardless of how deep it actually goes.
Takeoff Software For Construction
Everything downstream depends on the front of the chain being right. A procurement platform buying against a bad list orders the wrong material efficiently, and a job costing system reporting against a bad estimate reports a variance that was created before the crew arrived. Fixing the takeoff is the only change that improves every stage after it.
Future Trends In BOM Software For Construction
Three shifts are worth watching.
Automated generation is moving the work from measuring to reviewing, which changes what an estimator's day looks like and what the software has to prove, since the test becomes whether a reviewer can verify a line rather than how fast it was produced.
Supplier price feeds are becoming standard rather than premium, and with material volatility of the past few years that matters more than it used to, because a list priced six weeks ago is a different list today.
And the chain is consolidating, with takeoff, procurement and job costing vendors all extending into each other's territory. Contractors should expect fewer handoffs over the next few years and should still buy for the stage that is costing them money now rather than for a roadmap.
Conclusion
Work out which stage of the chain is leaking. If material lists take days to build and nobody can check them, the problem is at the front and no procurement platform will fix it. If the list is fine but you are paying retail for emergency orders, Kojo or your enterprise platform's purchasing module is the answer. If material cost never reaches job costing by code, that is an accounting integration problem rather than a bill of materials problem.
Start at the front, because every stage after it inherits whatever the first one produced. The Takeoff AI builds the list straight from the bid package with every line traceable to the element that created it, which gives procurement, purchasing and job costing something they can rely on.
