Managing subcontractor payments without killing your cash

Fourteen subcontractor invoices totaling $127K are due Friday. The general contractor draw covering that work pays in eleven days. Missing sub payments risks liens, delays, and damaged relationships. Paying from reserves drains the buffer you need for next week's payroll.

Subcontractor payment management is the daily cash balancing act that defines construction finance. You are paying for work performed before you collect for work billed. The gap is structural, and mismanaging it has legal and operational consequences.

Sub payment terms and expectations

Most subcontractors expect payment within 15 to 30 days of invoice. Your contract with the general contractor may specify Net 45 or Net 60 on draws. That 15 to 45 day gap between sub payment expectations and your collection timeline is the core cash challenge.

Experienced subcontractors know this gap exists and price it into their bids or demand faster payment terms. Newer subs may not, and delayed payment damages relationships that took years to build.

Lien waivers and payment timing

Lien waivers create a payment timing constraint. Subs provide conditional waivers with their invoices and expect unconditional waivers upon payment. GCs often require lien waivers before releasing draw payments. The documentation cycle adds days to an already tight timeline.

Track lien waiver status per sub per project. A draw held up because one $8K waiver is missing blocks collection on $220K in approved work. The administrative bottleneck has a direct cash cost.

Paying subs before getting paid by the GC

Paying subcontractors before collecting from the general contractor is standard practice, not a sign of poor management. It is the operating model. The question is not whether you pay first. The question is whether you have sized the cash buffer to fund that pattern across all active projects.

Calculate your sub payment float: total sub obligations due in the next 30 days minus expected draw collections in the same period. That number is your minimum cash requirement. If it exceeds available reserves, you need a credit facility or you need to negotiate faster draw cycles.

Cash buffer strategies

Maintain a dedicated sub payment reserve sized to your 30-day float calculation. Do not commingle it with operating cash. When draws arrive, replenish the reserve before deploying surplus elsewhere.

Negotiate partial upfront payments on large sub contracts to align their cash needs with yours. Schedule sub payments to cluster after expected draw collection dates rather than spreading them throughout the month.

Prioritize subs whose work is on the critical path. Delaying payment to a non-critical sub is less risky than delaying one whose absence stops work and triggers schedule penalties.

Weekly sub payment review

Review subcontractor obligations every Monday against expected draw deposits for the next 30 days. This single meeting prevents most payment crises. When the forecast shows a gap, you have the full week to accelerate a draw follow-up, arrange a line of credit draw, or negotiate a short extension with a sub you have paid reliably in the past.

Construction firms that model sub payment obligations against draw collection schedules maintain relationships, avoid liens, and enter each week knowing whether the cash is there or the credit line is needed.
