Siteline vs. Procore
Which is Right for Subcontractors?
Siteline and Procore solve different problems for subcontractors. Procore is a broad construction management platform often used by GCs and owners to manage projects, financials, and collaboration. Siteline is purpose-built for the subcontractor's billing workflow: pay apps, lien waivers, collections, A/R visibility, and cash flow.
That said, because Procore is so widely used across construction, many subcontractors end up asking: Do I need Siteline if my GC already uses Procore? Or should I use Procore for my own billing too? This page has the answers.
Siteline vs. Procore at a Glance
The Verdict
Most subcontractors working on Procore-managed projects use both tools. Siteline handles the sub-side billing workflow—pay apps, lien waivers, lien rights, collections, A/R reporting—and pushes finalized pay apps into Procore Pay. Procore alone doesn't replace Siteline for subcontractors who need a billing-first workflow with custom forms, collections automation, and cross-ERP integration. When subcontractors use Procore, they use it for its project management capabilities, not billing, which is built for the GC workflow.
Overviews
What is Siteline?
Siteline is billing software built specifically for commercial subcontractors. It manages the full monthly billing cycle: pay app generation with AIA®-style and custom GC forms, PM collaboration, lien waiver collection with AI validation, compliance document management, lien rights tracking, change order tracking, collections workflows, A/R reporting, billing projections, and cash flow forecasting.
Siteline integrates with more than 10 ERP and accounting systems, including Sage 300 CRE, Sage 100, Sage Intacct, Viewpoint Vista and Spectrum, Acumatica, CMiC, Foundation Software, and QuickBooks, and connects directly to GC portals like Procore Pay and Textura. Across nearly $14 billion in tracked receivables, Siteline customers achieve an average DSO of 52.6 days, compared to a construction industry average of 96 days.
Siteline is a strong fit for growing, mid-market, and enterprise commercial subcontractors with recurring monthly progress billing.
Procore is a cloud-based construction management platform used across the industry for project management, document control, financial management, preconstruction, and business intelligence. It is one of the most widely adopted platforms in commercial construction and integrates with more than 500 construction technology tools.
Procore's financial tools include invoice creation and approval workflows, budget management, change order management, cost forecasting, and Procore Pay. This payment module allows subcontractors to submit pay applications through the platform. Procore contracts include unlimited users and data, plus 24/7 support.
Procore is primarily designed around the needs of GCs and owners. For many subcontractors, Procore shows up as the GC's project and payment portal. Siteline is different because it gives the subcontractor its own billing and A/R workspace across all GCs.
Siteline vs. Procore: Feature Comparison
Where Siteline Wins for Subcontractors
Billing Workflow is Built for Your Company's Needs, Not Your Clients'
The most important distinction between Siteline and Procore is who each tool was designed to serve. Procore's invoicing module is built to help GCs collect and approve pay apps from their subcontractors. That means the workflows, forms, permissions, and reporting structures all center on the GC's view of the project. Many subcontractors use Procore to submit into a GC-controlled project workflow, but still need their own system to manage billing across every GC, form, waiver, and collection step.
Siteline is the opposite. Every workflow—form generation, PM notifications, lien waiver collection, collections follow-up, A/R reporting, etc.—is designed for the subcontractor's accounting team. When your billing coordinator opens Siteline, they see their work queue, not data they have to navigate around GC-owned fields to find.
Custom Forms Improve First-Time Approval Rates
Subcontractors working across multiple GCs deal with a different billing format for almost every project. One GC wants a sworn statement. Another requires a specific cover sheet, and a third needs certified payroll attached to the pay app. Procore's billing module has limited customization for sub-specific billing formats.
Siteline digitizes any GC-specific billing form to match their requirements and can then be used throughout the project. That translates into fewer pay apps being rejected and less rework for accounting teams. Universal Metro, a Siteline customer, eliminated pay app rejections after going live and reduced DSO by 10 days.
Lien Waivers Are Built Into the Billing Workflow
Procore offers limited lower-tier lien waiver support via its Procore Pay tool (which is built for the GC workflow), and its primary lien rights tool (Levelset) is a separate product with its own pricing and interface as well as a legal-first focus on preliminary notices and filing rather than the day-to-day waiver workflow.
Siteline's lien waiver management is embedded in the billing process. When you generate a pay app, Siteline surfaces the correct waiver to include. At the same time, vendor waivers get tracked, AI-validated, and can be automatically included in the billing package. Teams save 75 to 150 hours per year on waiver automation alone—a level of efficiency that's difficult to achieve when lien compliance lives in a separate tool.
Collections Automation Reduces DSO
Procore doesn't offer automated collections functionality for subcontractors. Once a pay app is submitted and approved, payment follow-up falls back on the accounting team via manual emails, calendar reminders, and phone calls.
Siteline automates that follow-up. When a pay app goes overdue, the system triggers GC reminders on a defined cadence. Siteline customers who activate automated collections see a median improvement of 11.2 days in time to payment. For a $50M subcontractor, even just a nine-day reduction in DSO frees approximately $1.23M in working capital.
A/R Visibility is Built for the Finance Team, Not the GC
Procore's reporting and analytics are strong, but they're designed for the GC to monitor project cost and payment status across their subcontractor base. A sub's controller logging into Procore to forecast cash flow for their own business runs counter to the product's intent.
Siteline gives controllers and CFOs a real-time view of A/R aging, payment status by project and GC, billing projections, and cash flow forecasts. This is built for the sub's finance team, not filtered through a GC's project management interface.
Where Procore Has an Edge
Procore is the GC Ecosystem
If your GCs use Procore, it becomes the system of record for project data, RFIs, submittals, drawings, and change orders—and it's where subcontractors access and collaborate on that information. Siteline doesn't replicate that. It doesn't try to. Siteline handles billing; Procore handles project collaboration.
If your business genuinely needs a single platform for both project management and billing, and you primarily work with GCs who run everything through Procore, then Procore's financial tools may be sufficient at low project volume. Most mid-size and enterprise subs find they need a dedicated billing layer as project volume grows, but smaller operations with simpler billing may not. That said, smaller subcontractors should evaluate whether Procore's broader platform scope and pricing model make sense if billing is the primary pain.
Procore's Integration Marketplace is Extensive
Procore integrates with more than 500 tools via its marketplace (including Siteline). For organizations that want to connect multiple construction technology systems through a single platform hub, Procore's ecosystem is broader than Siteline's. Siteline integrates deeply with its supported ERPs and GC portals, but it doesn't position itself as a platform hub. It positions itself as the billing layer that sits between your ERP and your GCs' billing portals.
Pricing
Siteline's pricing is based on monthly pay app volume and billed annually. Every plan includes unlimited users and offices, core billing and vendor management functionality (including pay apps, lien waivers, change order tracking, collections, PM collaboration, reporting and forecasting), one ERP integration, and GC portal integrations.
Plans also include free onboarding, training, a dedicated account representative, and ongoing support. Lien Rights Management is a paid add-on, and additional ERP integrations are charged per product. Siteline does not publish specific pricing tiers publicly; you'll receive a proposal based on your monthly pay app volume.
Procore also uses a custom quote model, with pricing dependent on company size, modules selected, and contract terms. All Procore contracts include unlimited users, unlimited data, free training, and 24/7 support. Procore does not publish pricing publicly.
Given that Procore is primarily a GC platform, subcontractors evaluating Procore as a billing tool should confirm which sub-specific billing features are included in their contract tier, as Procore's financial module depth can vary by package.

How Siteline and Procore Work Together
Siteline and Procore are not mutually exclusive. Many commercial subcontractors use both: Procore for project collaboration and Siteline for billing. Siteline's integration with Procore Pay lets customers submit pay apps and waivers directly to GCs working in Procore. Here's how that integration works:
- Your GC sends you a Procore invite (the same way they'd add a project manager to their directory) and installs the Siteline Connector from the Procore Marketplace.
- Project information, SOVs, and change orders flow from Procore Pay into Siteline.
- Your team updates invoices and generates pay apps in Siteline with all required forms and compliance documents.
- Finalized pay app data flows back to Procore.
- You go into Procore Pay to sign and submit.
In other words, Procore remains your GC's system of record, and Siteline becomes your billing workflow, handling the sub-side work before you submit. You can read more about the integration here.
Who Should Choose Siteline vs. Procore?
Who should choose Siteline?
Siteline is the right fit if:
- You're a commercial sub who submits recurring pay apps across multiple active projects and GCs
- Your billing team manages custom GC forms, compliance documents, and lien waivers for multiple active projects.
- Your accounting team needs A/R visibility, strong retention tracking, and cash flow forecasting that isn't dependent on your GCs' reporting.
- You want to automate collections follow-up without adding headcount.
- You're managing billing currently across your ERP or accounting system as well as spreadsheets, emails, PDFs, and other manual methods.
- You're concerned about pay app rejections causing payment delays.
- You want to track mechanic's lien laws and deadlines and submit notices alongside your billing and collections.
- You want to improve communication, collaboration, and efficiency across the entire billing workflow.
Siteline may not be the right fit if:
- You're a very small subcontractor with low monthly pay app volume and simple billing requirements.
- You're a residential subcontractor.
- Your billing complexity is low, and your current ERP or accounting system handles AIA®-style pay apps adequately.
- You're a GC (or a self-performing contractor working with subs) evaluating billing tools for the GC-to-owner billing workflow. (Siteline is built for subs.)
Who should choose Procore (or keep using it)?
Procore makes sense if:
- You need a single platform for project management, document control, and GC collaboration, with lightweight billing.
- Your GCs require Procore for project communication, RFIs, submittals, and drawing management.
- You're a GC or owner/developer evaluating construction management software.
- You want access to a broad marketplace of 500+ integration partners.
You might still want to add Siteline even if you're on Procore if:
- Your billing team is spending significant time building custom pay app packages outside of Procore's system.
- You're managing lien waivers and compliance documents manually or across disconnected tools.
- Your A/R aging and cash flow visibility are limited in your current setup.
- Pay app rejections are causing payment delays on Procore-managed projects.

Frequently Asked Questions
Yes, if you're a subcontractor. Procore is your GC's system for managing projects, collecting pay apps from subs, and tracking costs from their side. Siteline is your billing system, where you generate those pay apps, manage your custom forms, collect and validate lien waivers, track A/R aging, and automate collections follow-up. The two tools serve different sides of the transaction, which is why many Siteline customers submit to Procore-managed projects every month via Procore Pay.
Yes. Siteline integrates directly with Procore Pay. Project information, schedules of values, and change orders flow from Procore into Siteline. Your team builds and finalizes the pay app in Siteline, and that data flows back to Procore for signature and submission. Setup requires your GC to invite a Siteline account to their Procore directory and install the Agave API app from the Procore Marketplace. You can find full setup details at siteline.com/integrations/procore.
Procore includes invoice creation and approval workflows, and subcontractors can generate pay apps in AIA®-style G702®/G703® formatting through the software. For subcontractors with simple billing requirements and low project volume working primarily with Procore-based GCs, it may be sufficient. As billing becomes more complex, though, the gaps become harder to ignore. Procore offers limited customization for sub-specific billing formats, limited functionality for subcontractors initiating change orders, limited lower-tier lien waiver support, and reporting designed around the GC's view rather than the sub's A/R. Subcontractors managing multiple GCs, custom forms, lien waivers, and collections typically find Procore's billing tools insufficient for their daily workflow.
Not directly. Procore is a GC-facing construction management platform; Siteline is a sub-facing billing and A/R software. They operate on opposite sides of the payment application process and are therefore complementary tools. Siteline even integrates with Procore Pay, enabling subcontractors to use both.
The comparison is worth making because many subs encounter Procore on their GCs' projects and wonder whether they need a separate billing tool. For most commercial subcontractors doing meaningful monthly billing volume, the answer is yes.
Several features make Siteline a better fit for subcontractor accounting teams. It generates unlimited custom GC billing forms, not just standard AIA® forms, and includes a built-in lien waiver workflow with AI validation and automated vendor reminders. Siteline also automates collections follow-up and provides A/R aging reports, cash flow forecasting, and billing dashboards designed around the subcontractor's financial view. It integrates with more than 10 ERP and accounting systems, making it easier to connect billing with the rest of your financial workflow.
In short: Procore Pay is built to help GCs receive and process pay apps. Siteline is built to help subs generate, submit, and get paid on them.
Siteline integrates directly with Procore Pay. Project data, SOVs, and change orders sync from Procore into Siteline, where your billing team prepares the pay app and gathers all required documentation. Once it's finalized, the pay app syncs back to Procore Pay for signature and submission. This eliminates the double entry and manual re-keying that comes with preparing billing packages outside the portal. Siteline handles the prep; Procore handles the submission.
Based on Siteline's published content and product documentation, Procore has:
- limited customization for sub-specific billing formats,
- limited functionality for subcontractors initiating change orders,
- limited lower-tier lien waiver support,
- limited reporting designed for subcontractor A/R needs, and
- insufficient tools for tracking retainage at the subcontractor level.
Most Siteline customers are typically up and running within a few weeks, depending on billing complexity, ERP setup, and the number of active projects and GC forms that need to be configured. Siteline's onboarding team helps connect your ERP or accounting system, load your GC-specific billing forms, configure active projects, and train your team on the workflow.
For bulk setup, Siteline can also support project imports using structured templates when needed. The goal is to get your billing team live quickly with the right forms, data, and workflows in place, so they can start managing pay apps, waivers, and A/R in Siteline with confidence.
