Siteline vs. Trimble Pay
Which is Right for Your Construction Billing Workflow?
Trimble Pay and Siteline both deal with construction pay apps, lien waivers, and compliance documents. But they solve the problem from opposite sides of the transaction. Trimble Pay (formerly Flashtract) is built for general contractors (GCs) who need to collect documentation from their subcontractors and vendors. Conversely, Siteline is built from the subcontractors' perspective. Subcontractors use Siteline to generate, compile, and track that same documentation, and then submit it to their GC clients. If you're a subcontractor evaluating both, this page will help you understand the distinction.
Siteline vs. Trimble Pay at a Glance
The Verdict
Trimble Pay and Siteline sit on opposite sides of the same pay app transaction, so "which is better" depends entirely on which side of the desk you sit at. If you're a GC standardizing how subs submit documentation, especially one already running Trimble Vista or Spectrum, Trimble Pay's escrowed waiver vault and Trimble Construction One integration are real advantages. If you're a subcontractor who needs to generate, track, and submit your own billing across multiple GC clients and portals, Siteline is built for that job in a way Trimble Pay isn't, since Trimble Pay doesn't offer A/R reporting, DSO tracking, or collections automation for subs at all.
Overviews
What is Siteline?
Siteline is the only billing and accounts receivable software built specifically for subcontractors. It manages the full upstream billing workflow: pulling project data from your ERP, generating pay apps in whatever format your GC requires, tracking lien waivers and compliance documents, collecting lower-tier vendor waivers, and following up on overdue invoices with automated collections. Siteline integrates with major construction ERPs and pushes finalized pay apps directly to GC portals to eliminate double entry.
Subcontractors using Siteline beat the national average DSO for construction by 44% and speed up billing and lien waiver workflows by 6x. Specialty contractors across all trades, including structural steel, mechanical, electrical, masonry, glazing, and fire protection, leverage the user-friendly software.
Trimble Pay, formerly Flashtract, is a construction billing and compliance platform that joined the Trimble Construction One ecosystem in 2024. It's designed for general contractors who need to collect, review, and approve pay applications, lien waivers, and compliance documents from their subcontractors and vendors. Its core function is giving GCs a standardized, automated way to manage what their subs submit for payment on progress bills.
Subcontractors can access Trimble Pay to submit documents when invited by a GC, who pays for the product. Trimble Pay integrates with Trimble Vista, Trimble Spectrum, CMiC, Sage 300, and Procore. Siteline's own published comparison of top construction payment application software lists Trimble Pay in the GC tools category, not the subcontractor tools category.
Feature Comparison
The Real Difference: A/R vs. A/P
In subcontractor billing, every pay app transaction has two sides. The subcontractor manages the accounts receivable side: tracking work completed, compiling the pay app package, submitting it to the GC, and following up until payment arrives. The GC manages the accounts payable side: collecting documentation from subs, reviewing it for accuracy and compliance, and processing payment.
Trimble Pay is built for the A/P side. Siteline is built for the A/R side. This distinction shapes every feature decision each product has made, which is why their feature sets look so different despite both dealing with pay apps and lien waivers. That's why Trimble Pay competes with other GC-facing tools like GCPay, Textura, and Procore Pay, while Siteline integrates with them. In practice, Siteline's biggest competitor is billing spreadsheets.
Where Siteline Wins for Subcontractors
Billing and A/R Live Where Subs Work
Trimble Pay was built to solve a GC's problem: collecting documentation from subs. It was not built to solve a subcontractor's problem: getting paid faster across all projects and clients. That distinction shows up immediately in the toolset. Trimble Pay gives subs a submission portal for whichever GC has deployed it. Siteline gives subs a complete billing system: pay app generation, lien waiver management, retainage tracking, change order logs, and collections, all in one place regardless of which GC or portal is on the other end.
For a subcontractor managing projects across multiple GCs, that difference compounds fast. Trimble Pay only covers the projects where a specific GC has adopted it. Every other project still needs a separate process, which is exactly the fragmented, portal-by-portal patchwork Siteline is built to eliminate.
Access to A/R Reporting, DSO Tracking, and Collections Automation
Trimble Pay does not offer A/R aging reports, DSO tracking, or automated collections follow-up for subcontractors, because GCs don't need those tools to collect documentation from their subs. Subs do. Siteline gives accounting teams real-time visibility into what's outstanding, why, and for how long, plus automated reminders that chase down slow-paying GCs without manual follow-up.
Generate Custom Forms and Submit to Portals without Leaving the System
Siteline stores and generates forms for more than 24,000 GCs and submits directly to GC portals, like Textura and Procore Pay. Trimble Pay integrates with Vista, Spectrum, CMiC, Sage 300, and Procore on the ERP side, but it doesn't submit pay apps to portals outside its own system. Trimble Pay competes directly with other GC portals; Siteline doesn't.
Where Trimble Pay May Be a Fit
Portal Lives within the Trimble Construction One
For GCs already running Trimble Vista or Trimble Spectrum, Trimble Pay plugs directly into an ecosystem they've already invested in. That's a real advantage for GCs standardizing subcontractor payment collection without adding a separate platform. Siteline doesn't compete on that front as it isn't a GC-facing product.
Escrowed Lien Waiver Vault is Tied to ACH Release
Trimble Pay holds conditional lien waivers in escrow until an ACH payment clears, which is a well-designed risk-management feature for GCs managing legal and financial exposure across a large subcontractor base. Siteline doesn't offer an equivalent GC-side escrow mechanism, since that isn't the side of the transaction it's built for.
Free Access is Available for Subs Already Working with a Trimble Pay GC
If your GC has already standardized on Trimble Pay, submitting through it for that project is free and requires no separate purchase decision. For subcontractors whose work is concentrated with GCs on Trimble Pay, that's a low-friction way to handle submissions on those specific jobs, even though it doesn't address billing, A/R, or compliance for the rest of a sub's project portfolio.
Pricing
Siteline uses custom, usage-based pricing based on billing volume, project count, and integration needs. Every plan includes unlimited users and offices, dedicated onboarding, and access to the full billing and A/R workflow. Lien Rights Management is available as an add-on. Get a custom quote at siteline.com/pricing.
Trimble Pay doesn't publish subcontractor-facing pricing on its own site; Trimble's product page states that subcontractors can submit documents for free when invited by a GC, with the GC as the paying customer. That said, a third-party listing on Capterra shows two flat-rate tiers, $199/month for general contractors and $99/month for subcontractors, which doesn't match Trimble's current public messaging. The Capterra figures may be outdated or tied to when the product was Flashtract, so confirm pricing directly with Trimble Pay.
Customer Proof
Cooper Steel
Cooper Steel's billing process was fragmented across multiple systems, and routine work took far longer than it should. After implementing Siteline, Cooper Steel saved 22 hours per month across A/R workflows. Pay application processing time dropped by 15 minutes per project. Lien waiver management, previously a two-day task for two employees, became a half-day task for one. That time back went toward higher-value work.
Acme Erectors
Acme Erectors, a structural steel subcontractor, runs FOUNDATION for accounting and Siteline for billing. The result: a 19-day reduction in DSO (from 77 days to 58 days), a 10% increase in monthly billing volume, and 5 days saved per month on pay app processing for the A/R manager. The team also saved 16 hours per month on change order management.
Binswanger
Binswanger is a 600-person glazing contractor with 45 branch offices across the country. Before Siteline, each office managed billing differently, with its own folder structure, point person, and process for handling forms. Forty-six employees handled billing part-time in addition to their other responsibilities, while the finance team spent more than two hours per month just reviewing the status of open projects. Pay applications were taking 40 minutes each to compile. After implementing Siteline, Binswanger consolidated all billing operations into a dedicated team of four without losing capacity. Project managers now complete monthly billings for all their projects in under an hour. The finance team reviews open project statuses in under 15 minutes. DSO dropped from 60 to 54 over six months. And the estimating team gained something they did not have before: data on which GCs pay consistently and which ones don't, feeding directly into their bidding decisions.
A Note on Integration
Siteline and Trimble Pay do not currently integrate. That said, Siteline is part of Trimble's vendor network and integrates with both Viewpoint Vista and Viewpoint Spectrum on the ERP side, which is a separate connection from Trimble Pay. If your accounting system runs on Vista or Spectrum, Siteline connects to it directly for billing data syncs.

Siteline or Trimble Pay: Which to Choose?
Siteline is the right fit if:
- You're a commercial subcontractor managing billing across multiple GC clients with different form requirements.
- Your accounting team spends more than a few hours per month compiling pay apps manually.
- You work across different GC portals and want to eliminate double entry.
- You need A/R reporting, DSO visibility, and collections tools in the same platform as your billing.
- You want to track retainage, change orders, and compliance documents across a full project portfolio.
- You use Vista, Spectrum, Sage, Acumatica, Foundation, or another major ERP and want your billing synced to it.
Trimble Pay may be the right fit if:
- You're a general or prime contractor collecting pay apps and compliance documents from your subcontractors and vendors.
- You're already running Trimble Construction One and want an integrated payment workflow.
- You need an escrowed lien waiver solution tied to ACH payment release.
- You want to standardize how your subcontractors submit documentation to you.
- You already have a billing solution—like Siteline—in place, and you're looking for an A/P solution for managing your lower-tier sub billing. (Siteline has customers that use Siteline for their own billing and then use Trimble Pay to collect pay apps downstream.)
Frequently Asked Questions
Yes. Trimble acquired Flashtract in 2022 and rebranded the product as Trimble Pay. The core product serves the same function: a GC-facing tool for collecting pay applications, lien waivers, and compliance documents from subcontractors. The Trimble Pay name reflects its integration into the broader Trimble Construction One ecosystem, which includes Viewpoint Vista and Viewpoint Spectrum on the ERP side.
Subcontractors can submit documents through Trimble Pay when invited by a GC, and that access is free. But Trimble Pay is not a subcontractor billing tool. While it can generate custom pay apps for GCs, those forms are specific to GCs using Trimble Pay. It cannot generate any forms for GC clients outside of the Trimble Pay system. Furthermore, it does not track retainage or change orders across a project portfolio, provide A/R aging reports, automate collections follow-up, or integrate with other GC portals on the sub's behalf. Those workflows belong to the A/R side of the transaction, whereas Trimble Pay is built for the A/P side.
Siteline and Trimble Pay do not currently have a direct integration. Siteline is part of Trimble's vendor network and integrates with both Viewpoint Vista and Viewpoint Spectrum, both of which are Trimble's ERP products used by many subcontractors. That connection allows billing data to sync between Siteline and your ERP. It is a separate relationship from Trimble Pay, which handles GC-facing payment and compliance workflows.
Yes. Siteline integrates directly with both Viewpoint Vista and Spectrum. Project data, schedule of values, and invoice information sync between your ERP and Siteline so your billing team doesn't need to re-enter data manually. For a full list of supported integrations, visit siteline.com/integrations.
In the context of subcontractor progress billing, accounts receivable (A/R) falls under the subcontractor's workflow: compiling the pay app, submitting it to the GC, tracking approvals, and following up on payment. Accounts payable (A/P) is the GC's workflow: collecting pay apps and compliance documents from subs, reviewing them, and processing payment. Siteline is built for the A/R side. Trimble Pay is built for the A/P side. They operate on opposite ends of the same transaction.
Siteline is built for commercial subcontractors managing billing across multiple GC clients with varying form and portal requirements. It's a strong fit for subs that submit multiple pay apps per month, deal with varying GC requirements and forms, and manage lien waiver requirements, retainage tracking, and change order management as part of their regular billing cycle. Siteline also has lien rights tracking, automated collections, forecasting, and A/R reporting. Specialty trades—including structural steel, mechanical, electrical, masonry, fire protection, and glazing—are well-represented in Siteline's customer base.
Yes. If your GC requires submissions through Trimble Pay, you would continue to submit through that portal as required by your client. Siteline manages your billing workflow on the sub side: compiling the pay app, tracking your SOV, handling lien waivers, and maintaining your A/R reporting across all your projects. Submission through GC-mandated portals is a separate step that Siteline supports for Textura, GCPay, and Procore Pay. For Trimble Pay specifically, you'd generate everything you need in Siteline, download the documents, and then log into Trimble Pay to manually upload and submit your materials. Siteline's value is in centralizing everything that happens before and after that submission.
