6 Best Subcontractor Prequalification Software for 2027

Subcontractor prequalification software stores the evidence a general contractor collects before awarding work, such as financial statements, safety records, licenses, and insurance certificates, and it records the decision so the next project can reuse it. Before comparing products, decide which job you are buying. Most buyers need one of four things: a standardized questionnaire or shared network that subcontractors complete once, an outsourced review where analysts read the financials for you, a prequalification module inside the project system you already run, or a workflow layer that moves approvals, reminders, and records between the tools you already have. The first three are what the six tools below mainly sell. US Tech Automations belongs to the fourth category, which means it can sit above a prequal record instead of replacing one.

TL;DR: Choose the job first, then the tool. Among the six profiled vendors, only Constrafor publishes dollar figures for general contractors on its own pricing page. PreQual's figures appear in its vendor-written article, and the other vendors quote on request or show no amounts. Budget against written quotes, not against list-style comparisons.

Key Takeaways

• Pick the job first: expert financial review, a shared subcontractor network, a module inside your project system, or a workflow layer that sits above a prequal record.

• PreQual's self-service rate is $6 per subcontractor, but its listed $10,000 annual minimum sets the real floor for smaller subcontractor lists.

• Constrafor is the only profiled vendor whose general contractor price is stated by annual construction volume band on its own site, though its prequalification product page could not be verified.

• Procore Prequalification, TradeTapp, and COMPASS are quote-based in the sources we checked, so get written totals before comparing costs.

• Vendor-written roundups rank or describe their own products, so treat their claims as things to test, not neutral rankings.

• Workflow automation can route, remind, and record prequal decisions, but the approval and the underlying evidence still need a named human owner.

Who this is for

You are a general contractor or construction firm that hires subcontractors on a recurring basis and needs to show why each one was approved. Your stack usually includes an accounting system, an email or CRM tool, and either a project platform or a set of spreadsheets. The pain is uneven financial review across estimators, slow subcontractor onboarding, and insurance certificates that expire unnoticed until someone is about to pay.

Red flags: you need a shared network of pre-vetted subcontractors more than you need your own vetting record; no one on your team owns the approval criteria; or you expect a tool to produce financial or safety evidence that subcontractors never submit.

How we checked this list

We read each vendor's own pricing or product pages where they loaded, and used third-party coverage where they did not. The TradeTapp overview page returned a 403 error during our check, and COMPASS's own site redirected to a page that returned a 404, so those rows rest on third-party coverage. Constrafor's prequalification product page also returned a 404, so its prequal features are not verified; only its pricing is. Vendor-authored claims are labeled as such. Highwire's roundup covers ten platforms and is discussed only as a source of claims, not as a ranking we adopt.

Evaluation criteria and weights

The weights below are our analysis, not vendor data. They reflect what a general contractor should prioritize, and you should change them to match your own risk profile before you score any tool.

Normalized feature matrix

Each cell records what a source states. "Not verified" means we could not confirm the capability from a vendor page or a named third party. It does not mean the capability is absent.

Subcontractor prequalification software pricing

Pricing checked October 20, 2026 against the live Constrafor, Procore, Contractor Compliance, and US Tech Automations pricing pages. PreQual's own page lists no prices, so its figures come from Vertikal RMS's January 4, 2026 article and from Construction Placements' June 25, 2026 update. Construction Placements repeats the same PreQual rates without the minimum, so treat the two as one data point, not two confirmations.

PreQual self-service: $6 per subcontractor according to Vertikal RMS (2026), with a $10,000 annual minimum and $4,200 to $6,000 implementation. The minimum changes the math. At an illustrative 150 prequalifications a year, $6 per subcontractor comes to $900, far below the minimum, so the $10,000 figure would set the floor if the minimum works the way the table implies. Vertikal's table does not explain how the minimum interacts with per-review fees, so confirm the billing terms in writing before you budget.

Table 3 converts the published figures into a first-year comparison. The 150-prequalification volume is an illustration to make the arithmetic comparable, not a recommended threshold.

Vertikal's market context puts general contractor-paid models at about $3,000 to $15,000 per year according to Vertikal RMS (2026), while the same article describes subcontractor-paid models from $1,000 to $40,000 or more per subcontractor. Because Vertikal sells PreQual, read those ranges as one vendor's framing, not market data.

Constrafor general contractor tier: $13,500 per year under $500M volume according to Constrafor (2026). The page moves to $25,000 for $500M to $1B and $40,000 for $1B to $3B. It does not define annual construction volume, and it describes "unlimited platform access" with "as many users and subcontractors as you need," so it is a platform fee, not a per-review fee.

Procore charges an upfront annual fee by product based on annual construction volume, according to its pricing page, and that page gives no prequalification figures. The roughly $375 per month figure that appears in Construction Placements' roundup cites unnamed industry reports, so do not budget from it without a quote.

Why prequal is moving into software

Adoption is rising but not universal. Regular prequal software use: roughly 49% in 2025 to 52% in 2026 according to BuiltWorlds (2026). The sample size was not stated on the page we read, so treat the change as directional. The pressure behind the shift is clearer: Subcontractor distress or defaults: 70% of respondents according to AGC (2024 AGC/FMI study), and nearly half of those respondents reported project disruption from subcontractor defaults.

Prequal vs TradeTapp vs COMPASS

BuiltWorlds lists TradeTapp among the most commonly cited prequalification solutions and places COMPASS next, which is why these three come up most often in comparisons. They solve different problems, so the right question is which one matches your bottleneck.

The practical difference is who does the work. PreQual can outsource the analysis for a per-review cost. TradeTapp's value depends on whether your subcontractors and trades already sit inside Autodesk's network. COMPASS reduces subcontractor effort by standardizing the form, but it standardizes the input, not your decision criteria, so you still need your own approval rules.

Vendor profiles

Each profile separates sourced facts from our read.

1. PreQual by Vertikal RMS

Best fit: General contractors without in-house financial analysts who want outside review of subcontractor financials and can accept a minimum annual commitment.

Sourced facts: Vertikal's article lists self-service at $6 per subcontractor and full-service at $30 to $165 per prequalification, both with a $10,000 annual minimum and $4,200 to $6,000 implementation. PreQual's own page says the self-service tier is "software only" without expert support, and it lists a "vendor pay option" without explaining who pays under it. The article also says PreQual integrates with CertFocus for certificate tracking.

Limitations: Self-service excludes expert support. Pricing appears only in a vendor-written article, and the minimum's interaction with per-review fees is not explained anywhere we could find.

Implementation: PreQual's page says it is "compatible with internal systems," and Vertikal's table lists $4,200 to $6,000 for implementation.

Our read: Choose it if you want analyst review and will pay for it. If your team already reviews subcontractor financials well, a software-only tier may not justify the minimum at your volume, so price it against your current review hours.

Evidence: Vertikal RMS best-of article and PreQual product page.

2. Constrafor

Best fit: General contractors that want a fixed annual price by volume band, unlimited users and subcontractors, and a free trial before committing.

Sourced facts: Constrafor's pricing page lists $13,500 per year under $500M in annual construction volume, $25,000 for $500M to $1B, and $40,000 for $1B to $3B. The first three tiers show a "Start free trial" button with no trial terms. The page lists full-scale onboarding support and unlimited platform access among what is included. Vertikal's article describes a universal prequalification form and says subcontractors use Constrafor for free.

Limitations: Constrafor's prequalification product page returned a 404 during our check, so its prequal features, workflow, and integrations are not verified. The pricing page does not define annual construction volume. The homepage's figures, such as a 40,000-plus contractor network and SOC 2 certification, describe the company as a whole, not the prequalification product.

Implementation: Onboarding support is listed on the pricing page. We did not find implementation timelines.

Our read: Constrafor is the only profiled vendor whose general contractor price is stated by volume band, which makes it the easiest to budget. Test the prequalification depth during the trial before committing, because the sources available to us do not describe it.

Evidence: Constrafor pricing.

3. Procore Prequalification

Best fit: General contractors that already run projects in Procore and want approved vendors to flow into bidding and the Directory.

Sourced facts: Procore describes configurable questionnaires, a library of standard questions, a vendor-facing portal, a central record of approved vendors, and invitations to bid for approved firms. Its pricing page says it charges "an upfront annual fee by product" based on annual construction volume and directs buyers to a customized estimate. Highwire describes Procore's prequalification as less specialized than dedicated tools, but convenient because it connects to the rest of the project platform.

Limitations: Prequalification is a module inside a broader platform, so the decision depends on whether you already use Procore. The pricing page gives no prequalification-specific figures, and the $375 per month estimate is unconfirmed.

Implementation: Implementation runs through your existing Procore setup. We did not verify onboarding steps or timelines.

Our read: Choose it when the record of vendor approval belongs in your project system. If your prequal decisions happen outside Procore, a standalone tool or workflow layer may fit better.

Evidence: Procore Prequalification, Procore pricing, and Highwire's roundup.

4. Autodesk TradeTapp

Best fit: General contractors already inside Autodesk Construction Cloud or BuildingConnected that want to qualify subcontractors against a very large base.

Sourced facts: Construction Placements reports over 250,000 registered subcontractors and quote-based pricing. Highwire says TradeTapp focuses on financial risk assessment and subcontractor qualification and is most commonly used by general contractors inside Autodesk's ecosystem. Vertikal's article lists automated financial benchmarking and a mobile interface.

Limitations: Autodesk's TradeTapp overview page returned a 403 error during our check, so the network size and feature list rest on third-party coverage. The Capterra reviews we found are from 2017 and 2022. The 2017 review noted missing workflows to automate the review process, and the 2022 review praised reminders.

Implementation: Depends on your Autodesk setup. We did not verify onboarding terms.

Our read: A network that large helps when you need a wide search across regions or trades. It helps less when your work depends on a short list of local subcontractors you already know, because a network count is not the same as qualified coverage in your trade.

Evidence: Construction Placements roundup, Highwire's roundup, and Capterra's TradeTapp listing.

5. COMPASS by Bespoke Metrics

Best fit: General contractors that want subcontractors to complete one standardized form for many general contractors, with risk analytics on top.

Sourced facts: Highwire describes a "standardized, one-form model" in which subcontractors complete one common questionnaire. Vertikal lists Q Score risk analytics, a prequalified subcontractor network, Procore integration, and a 92% surety acceptance rate. Construction Placements says pricing is custom quote-based.

Limitations: COMPASS's own site could not be retrieved; the redirect returned a 404. Every feature in this profile therefore comes from third-party roundups, and the 92% surety figure is a vendor claim published in a competitor's article. Treat it as unverified.

Implementation: Not verified.

Our read: The one-form model helps most when your subcontractors already work across several general contractors. It helps less if you need your own financial review standard, because the form standardizes the input, and you still need your own approval rules.

Evidence: Highwire's roundup, Vertikal RMS article, and Construction Placements roundup.

6. Contractor Compliance

Best fit: Teams whose main risk is compliance documentation and permits across job sites, particularly if they already use VelocityEHS products.

Sourced facts: The Contractor Compliance homepage says the company is now a VelocityEHS solution. It mentions managing permits in one place and "real-time visibility and control over compliance across all job sites." Its headline claims it reduces compliance admin, but the page does not explain how that was measured. The pricing page shows no dollar amounts and splits into two paths, "I Hire Contractors" and "I Am A Contractor," without describing what each includes.

Limitations: The pages we checked do not describe prequalification questionnaires or certificate-of-insurance workflows, so those capabilities are not verified. Highwire and Vertikal both list VelocityEHS's Contractor Safety product as a separate platform, so confirm which product you would be buying.

Implementation: Not verified.

Our read: It is a credible candidate if your need is compliance tracking and permits more than financial prequalification. Choose it only after a demo confirms the prequalification workflow you actually need.

Evidence: Contractor Compliance pricing.

Where US Tech Automations fits, and when it does not

US Tech Automations does not run a subcontractor network, a financial review service, or a prequalification database. Its public pricing page describes ready-made AI workflows for customer email, invoice follow-up, deadline tracking, and ticket triage, sold on monthly plans with a 14-day free trial. The site does not mention subcontractors, prequalification, certificates of insurance, or construction. A prequal design would therefore be a custom scope, and the Performance tier is priced after a discovery call.

The plan limits matter for scoping. The Solo plan is $117 per month for 3 active workflows and 1 team member. The Growth plan is $447 per month for 5 active workflows, and the Scale plan is $1,647 per month for 10 active workflows with custom integrations and write-your-own code steps. Yearly billing is discounted, which the page describes as saving 17%.

When NOT to use US Tech Automations: Skip a workflow layer if your prequal system already handles the one step you need, such as Procore's built-in vendor approval feeding your bidding, because an added layer is a second system to maintain. Skip it if you need financial analysts to review submissions, since an orchestration layer does not provide that evidence. Skip it if your only problem is a missing form, which a standalone questionnaire or a prequal vendor solves without a custom workflow. Use one only when a prequal decision already exists and the handoffs around it are the real bottleneck.

The realistic alternative for many general contractors is not doing nothing. It is a stitched setup: a form tool, a shared drive, a spreadsheet, and a no-code automation tool such as Zapier, Make, or n8n. Those tools can keep run histories, retry failed steps, branch on errors, and produce audit evidence when configured. The buyer still has to design and own idempotency so a repeated trigger does not create a duplicate approval, plus escalation paths, access controls, retention periods, and maintenance when connected apps change. A workflow built on a layer like this would be scoped differently: a trigger when a prequal decision is recorded, a certificate-expiry check, a required human approval before any accept or reject status changes, and a write to your accounting or CRM record. The prerequisites are an export or webhook from the prequal system, scoped integration accounts, a written retention rule, and a named reviewer. The public site cannot answer whether those prerequisites are available in your stack, so that scoping has to happen with the vendor.

Worked example: prequal approvals into accounts payable

A general contractor with 180 active subcontractors and 150 new prequalifications a year keeps approved vendor records in QuickBooks Online, and this scenario is illustrative, not a benchmark. After each approval, a workflow reads the Vendor record and compares MetaData.LastUpdatedTime with the approval date, so any record untouched for 365 days creates a re-review task for the approver, and no payment hold is released without a named person signing off. At PreQual's self-service rate of $6 per subcontractor, the 150 reviews would cost $900 a year, far below the $10,000 annual minimum in Vertikal's table, so the minimum would set the cost if it works as a floor. A design like this would need a named approver for each flagged record, an escalation path for any record that fails the check, and a retained log of every decision, and the buyer would have to design and own all three.

Vetting a small general contractor without a platform

A smaller general contractor can start with a shared folder, a standard questionnaire, and a checklist covering licenses, certificates of insurance, and recent financials, without buying software. Constrafor's pricing page shows free trials on its first three tiers, and Vertikal's article says subcontractors can use Constrafor for free, so the subcontractor side can cost nothing. We did not find a vendor-published free form that a general contractor can use without a subscription.

The tradeoff shows up later as rework. A spreadsheet does not send expiry alerts, keep an audit trail, or share an approval history across projects. Choose a manual form while the process still works reliably for your volume, and move to software when reminders, expiry tracking, or approval history start breaking down.

Decision checklist

• Name the job you are buying: expert review, a shared network, a project-system module, or a workflow layer.

• Write your approval criteria and weights before any demo or trial.

• Request written quotes that include minimums, per-review fees, and implementation costs.

• Confirm whether a stated minimum is a floor or a prepayment.

• Confirm what the base or self-service tier excludes.

• Test the shortlisted tool with three real subcontractor files, including one you would reject.

• Confirm where certificates of insurance are tracked and who receives expiry alerts.

• Name one owner for approvals and one for escalations.

Glossary

• Prequalification (prequal): The review of a subcontractor's qualifications before a contract is awarded.

• Certificate of insurance (COI): A document that shows a subcontractor's insurance coverage and limits.

• Annual construction volume (ACV): The yearly construction value that vendors such as Constrafor and Procore use to set price bands. Constrafor's page does not define it.

• Full-service vs. self-service: Outside analyst review versus software-only use, as PreQual describes its two tiers.

• Standardized questionnaire (one-form model): A single subcontractor form shared across general contractors, as COMPASS describes its approach.

• Surety: A company that issues bonds guaranteeing a contractor's performance on a bonded project. Surety acceptance rates in our sources are vendor claims.

• System of record: The one place where a subcontractor's approved status is kept as the reference.

• Idempotency: A workflow property meaning a repeated trigger does not create a duplicate approval or record.

Frequently asked questions

Is there a free subcontractor prequalification form?

You can run a free form yourself using a standard questionnaire and a checklist, but we did not find a vendor-published free form for general contractors in our research. Vertikal's article says subcontractors can use Constrafor for free, while Constrafor's general contractor pricing starts at $13,500 per year.

How much does subcontractor prequalification software cost?

It depends on the model. PreQual's self-service tier is $6 per subcontractor with a $10,000 annual minimum, its full-service review runs $30 to $165 per prequalification, and Constrafor's general contractor tiers start at $13,500 per year. Procore, TradeTapp, COMPASS, and Contractor Compliance quote on request or show no amounts, so get written totals before you compare.

How does PreQual differ from TradeTapp and COMPASS?

PreQual sells software-only self-service or analyst-backed full-service review. TradeTapp sits inside Autodesk's ecosystem and claims a network of over 250,000 registered subcontractors. COMPASS standardizes one form that subcontractors complete for multiple general contractors. COMPASS's own site could not be retrieved, so verify its claims directly before relying on them.

Do I need separate prequal software if we already use Procore?

Not necessarily. Procore Prequalification keeps approved vendors in one record and links them to bidding, so start there if your project record already lives in Procore. Confirm your edition and pricing with Procore, because its pricing page gives no prequalification-specific figures.

Where does a workflow layer fit next to a prequal tool?

A workflow layer sits above the prequal record. It can route approvals, chase missing documents, and write results to your systems, but it does not supply subcontractor evidence or a review service. Because its public site does not mention construction or prequalification, any design needs a separate scope.
