Siteline Review 2026: Billing and A/R Software Built for the Subcontractor’s Side of the Pay App

Updated October 23, 2026 – Tested Intelligence

Quick verdict: Siteline is the rare construction billing tool built for subcontractors rather than GCs: it generates pay apps in whatever form each GC requires, manages lien waivers and compliance documents, and chases overdue invoices with automated collections. Pricing is custom and usage-based, with unlimited users. If you are a GC looking to collect documents from subs, this is not your tool – it serves the other side of the desk.

What it is

Siteline describes itself as 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 applications, tracking lien waivers and compliance documents, collecting lower-tier vendor waivers, and following up on overdue invoices. GetApp’s listing summarises the same benefits – simplified pay app management, automated lien waiver collection, compliance tracking, and real-time A/R reporting and forecasting.

Most pay app tools are bought by GCs to collect paperwork from subs. Siteline is bought by the sub – to bill correctly across every GC and portal, and see who owes what in one place.

Key features

• Pay app generation with custom GC forms: Siteline says it stores and generates forms for more than 24,000 GCs, including AIA-style G702/G703 billing
• Lien waiver management for primary and lower-tier waivers, with AI validation of waiver documents
• Compliance document tracking, so a missing certificate does not quietly hold up payment
• Retainage tracking and change order logs tied into the billing workflow
• Real-time A/R reporting, DSO tracking and cash flow forecasting built for the sub’s side
• Automated collections: reminders and follow-up on overdue invoices without manual chasing
• Billing deadline reminders across the project portfolio
• ERP and portal integrations: 10+ accounting and ERP systems, including Vista, Spectrum, Sage, Acumatica and FOUNDATION, with submission to GC portals such as Textura and Procore Pay

Pricing

Pricing is not a published rate card. Siteline’s own pricing information describes custom, usage-based pricing tied to billing volume, project count and integration needs. Every plan includes unlimited users and offices and dedicated onboarding, with no per-seat fees; Lien Rights Management is an add-on. Ask what the Lien Rights add-on costs before signing.

Who it’s for

Commercial subcontractors and specialty contractors – steel, mechanical, electrical, masonry, glazing, fire protection and similar trades – billing multiple GCs, each with different forms and portals. Siteline’s site claims a customer average of 52.6-day DSO against a 96-day industry average – a vendor claim, but it shows the outcome sold: getting paid faster.

Who should skip it

General contractors: Siteline is deliberately sub-facing and does not try to be the GC’s collection system. Very small subs billing one friendly GC on a simple spreadsheet will also struggle to justify a dedicated platform – the value appears when forms, portals and overdue accounts multiply.

Pros

• Built for the subcontractor’s A/R workflow, not adapted from a GC tool
• One system covers pay apps, waivers, compliance, retainage and collections
• Unlimited users and offices on every plan – no per-seat penalty for involving PMs
• Submits into the GC portals subs are forced to use, instead of adding another silo

Cons

• No published pricing – the quote depends on billing volume, projects and integrations
• Lien Rights Management costs extra as an add-on
• Value depends on connecting your ERP; a sub on lightweight accounting gets less from it
• It does not serve the GC side at all, so GC-mandated portals still exist in your process

FAQ

How much does Siteline cost?

Pricing is custom and usage-based, tied to billing volume, project count and integration needs. Plans include unlimited users and offices; Lien Rights Management is a paid add-on. You will need a quote from Siteline.

Does Siteline replace our GC portals?

No – it submits to them. Siteline generates the pay app in the GC’s required form and pushes it to portals such as Textura and Procore Pay, so the sub stops re-keying the same billing into different systems.

Which accounting systems does Siteline integrate with?

Siteline lists 10+ ERP and accounting integrations, including Viewpoint Vista, Spectrum, Sage, Acumatica and FOUNDATION.

Bottom line

For a commercial sub juggling GC forms, waivers and slow payers across dozens of jobs, Siteline attacks the exact admin that delays payment – and it is designed from the sub’s chair. Get the quote in writing and judge it against the hours your billing cycle burns.
