Construction Invoice Collection Best Practices
Retention, lien deadlines, and pay-when-paid clauses make construction the hardest industry to collect. Here's a process built around those realities.
By Doug Dunlap, Founding Sales Rep ·
Construction carries the highest average DSO of any industry CashLine tracks, 83 days, against a 58.4 day average across all industries. That gap isn't a sign of poor collections practices alone, it reflects how the industry is structured to pay, retention, conditional payment terms, and lien mechanics that don't exist in most other sectors.
Why Construction AR Is Uniquely Hard
Retention held for months or years. Standard contracts hold back 5 to 10% of every payment until substantial or final completion, sometimes long after a crew has moved to the next job.
Pay-when-paid and pay-if-paid clauses. Subcontractors are often contractually tied to when the general contractor is paid by the owner, adding delay outside the sub's control.
Lien rights and notice deadlines. Preliminary notices, mechanics liens, and bond claim deadlines vary by state and are unforgiving, missing one means losing real leverage on a disputed payment.
Change order disputes. Work performed under an unapproved or disputed change order routinely gets excluded from payment until resolved, and resolution can outlast the original scope of work.
Best Practices
- Track retention against specific release milestones, not generic aging buckets.
- Monitor lien and notice deadlines by state alongside AR aging, so a payment dispute never also costs you your lien rights.
- Resolve change order disputes quickly, with a documented trail, so the same CO doesn't stall payment indefinitely.
- Align pricing and internal expectations to the industry's real payment cycle, not a generic 30-day assumption.

Frequently Asked Questions
Retention holdbacks, pay-when-paid clauses, and lien notice complexity all add structural delay that most other industries don't face. Construction averages 83 days industry wide, the highest of any sector tracked, compared to a 58.4 day average across all industries.
Retention should be tracked against its specific release condition, substantial completion, final completion, or another contractual milestone, not lumped into standard aging buckets where it can make DSO look artificially high or obscure real risk.
Yes, significantly. Missing a preliminary notice or lien filing deadline can mean losing real leverage on a disputed payment regardless of whether the underlying work was performed correctly. Lien deadlines should be tracked alongside AR aging, not as a separate, disconnected process.
A pay-when-paid clause ties a subcontractor's payment to when the general contractor is paid by the owner, adding a layer of delay the sub doesn't control. Collections strategy needs to account for this dependency rather than treating every invoice as independently collectible on a standard timeline.
