Why Subcontractor Payments Take So Long, and How GCs Cut That Time

General contractors get paid within 30 days more than twice as often as their subcontractors do. That single comparison, from Levelset's 2022 Construction Cash Flow & Payment Report (519 construction companies surveyed), is the cleanest evidence that a payment delay isn't really about the owner or the bank. Most of it happens in the paperwork exchanged between GC and sub, the part both sides can actually fix.

This is a data-first look at where a construction payment cycle stalls and what closes each gap, not another pay app comparison. We already wrote that one. This is the layer underneath it.

The numbers, with sources

• Construction's average Days Sales Outstanding runs around 90 days, roughly double the 45-day mark healthy commercial businesses hit (Levelset, 2022 report, referencing industry DSO research).
• Only 5% of subcontractors report always being paid on time, against 21% of general contractors (Levelset, 2022, 519 companies surveyed).
• Slow payment is estimated to drain $280 billion a year from the US construction industry as of 2024, up from $208 billion in 2022 and $100 billion in 2020 (Rabbet's construction payment survey data, via DocJoist's 2026 construction payment statistics report).
• 74% of contractors reported moderate to severe cash-flow challenges in 2024 (Dodge Construction Network, per the same DocJoist compilation).
• The average wait between submitting a pay app and receiving payment runs about 56 days (Billd, 2025 data).

Read those together and a pattern shows up: it's not that owners refuse to pay. It's that the distance between "work done" and "check cleared" has too many manual steps, and every one of them adds days.

The three points where a payment cycle actually stalls

1. Pay app review on the GC side. The schedule of values gets reconciled against actual work in place, retainage gets recalculated, and someone checks the math before it goes to the owner or lender. This is what pay app software (Procore Pay, Siteline, GCPay, Trimble Pay, Built) is built to speed up. We compared all seven of the major tools here.

2. The lien waiver. Most states require a signed waiver before a payment releases, and the form has to be the right one, conditional or unconditional, progress or final, in the wording that specific state's statute requires. When this step runs on email, it's the one most likely to stretch a same-week payment into a two-week one. Nobody re-keys a schedule of values for it, they just wait on a signature.

3. Owner or lender draw timing. Once the GC submits, disbursement runs on the owner's or lender's schedule. This piece sits furthest from a GC's direct control, though a clean, complete draw package (pay app plus every waiver already signed) gets reviewed faster than one an accountant has to chase pieces for.

Of the three, the lien waiver step is the one most GCs treat as an afterthought and the one that's cheapest to fix. It doesn't require new accounting software or a lender conversation, just a faster way to get a signature.

What "payment transparency" actually means here

A transparent payment process is one where the GC and the subcontractor are both looking at the same status, not one where the sub calls the office to ask. In practice that means two things exist somewhere the sub can see them: where the pay app sits in approval, and whether the compliance paperwork, the lien waiver, is signed. Most GCs have the first (a pay app tool or at minimum a spreadsheet). Far fewer have the second visible to the sub at all, it usually lives in an email thread only the office manager can search.

What actually closes the gap

Bottleneck	What fixes it	Where to start
Pay app review is slow or manual	Pay app software with schedule-of-values tracking	Compare the 7 major tools
Retainage math gets argued over	A retainage calculator both sides trust	Free retainage calculator
Lien waivers get chased by email	Dedicated lien waiver software with statutory forms	LienDone, $99 a month
Nobody has one place to check status	A compliance dashboard both GC and sub can reference	Covered by most lien waiver and pay app tools

Where LienDone fits, honestly

LienDone is not a pay app platform and doesn't try to be. It's the second row in that table: a dedicated lien waiver layer that runs alongside whatever a GC already uses for billing, or alongside nothing at all for a GC still running pay apps as a PDF. The subcontractor gets a link, signs on their phone in about two minutes with no account to create, and the signed PDF lands in the GC's dashboard the moment they submit. Statutory forms cover 12 states word for word (California, Texas, Florida, and nine others), with a standard compliant form for the rest. Flat $99 a month, no per-waiver or per-seat charge, 14-day free trial.

If the slow part of your payment cycle is the billing side, one of the seven pay app tools compared here is the right purchase. If it's the waiver chase, that's the gap LienDone was built for.

The takeaway

Owners aren't the reason subcontractor payments run slow. The distance between a completed pay app and a signed lien waiver is. Fix the pay app side with the right billing tool, fix the waiver side with a signing flow subs will actually use, and the 56-day wait starts closing from both ends.
