Monthly vs. Twice-Monthly Draw Schedules: A GC Case Study

The Short Answer

Billing twice a month instead of once can cut your average cash gap in half on a large project. The catch is that owners and architects resist it, and you have to negotiate the right terms before you sign the contract, not after the job starts.

The Scenario: Millbrook Office Renovation, $4.2M Contract

Meridian Construction is a 35-person commercial GC with a solid backlog and a consistent cash problem. They win a $4.2 million interior renovation for a regional insurance company. The project runs 11 months. Meridian carries roughly $2.1 million in monthly subcontractor and material costs at peak.

The owner's standard contract calls for monthly draw submissions on the 25th of each month, with payment due 30 days after the architect certifies the application. Certification typically takes 7 to 10 business days after submission. That structure puts Meridian's realistic payment window at 37 to 40 days after each billing date.

Meridian's controller, Dana, runs the numbers before execution. At $2.1M in monthly field costs, a 37-day payment cycle means Meridian is financing roughly $2.58M in work-in-place at any given peak month. Their $1.5M line of credit covers it, but just barely, and only if every payment comes in on time. It rarely does.

The Negotiation: Pushing for a Semi-Monthly Draw Schedule

Dana brings the cash flow projection to the owner's representative three weeks before contract execution, while terms are still on the table. This timing matters. Owners are far less flexible once they've routed the agreement through legal review and the CFO has signed.

The ask: replace the single monthly billing with two draws per month, submitted on the 10th and 25th. Dana frames it not as a financing request but as a project-management benefit. Two billing cycles mean the GC tracks cost more frequently, catches schedule-of-values errors earlier, and keeps subcontractors paid tighter, which reduces the risk of a sub walking off the job mid-project.

The owner pushes back on architect review load. Certifying two applications a month instead of one doubles the architect's administrative time, and the owner pays that fee. Dana's counter is straightforward: the application on the 10th covers only work completed in the first half of the month. Each individual application is smaller and simpler to review than one large end-of-month billing. Total review time per billing cycle drops, even if frequency doubles.

The parties land on a modified structure:

• Draw 1 (10th of each month): Covers labor and installed materials from the 1st through the 10th. Payment due within 21 days of architect certification.
• Draw 2 (25th of each month): Covers the balance of work through the 25th. Payment due within 21 days of architect certification.
• Retainage held at 10% on both draws through substantial completion.

The architect's certification window stays at 7 to 10 business days. Meridian's realistic payment receipt moves from 37 to 40 days per billing to 28 to 31 days per billing, and they receive funds twice as often.

Running the Numbers

Here is how the two structures compare at project peak, month 6, when Meridian's gross billings hit $420,000 for the month:

Monthly billing (original): Meridian submits $420,000 on the 25th. After a 9-business-day certification and 21-day payment window, cash arrives roughly 37 days later, in early the following month. Meridian finances $420,000 for 37 days, plus the carry on the previous month's retainage.

Semi-monthly billing (negotiated): Meridian submits $195,000 on the 10th (first-half work) and $225,000 on the 25th (second-half work). The first draw pays out around the 31st of the same month. The second draw pays out around the 15th of the following month. Average days of float per dollar drops from 37 to approximately 18 to 21 days. Meridian's peak financing need shrinks from $420,000 to roughly $225,000 in outstanding receivables at any given point.

Over the 11-month project, Dana calculates that the semi-monthly structure reduces Meridian's average line-of-credit draw by $180,000 to $200,000. At their bank's 8.5% annual rate, that saves roughly $13,000 to $15,000 in interest, without cutting a single cost on the job. That is money that flows directly to the bottom line.

Subcontractor Payment Alignment

Meridian passes a version of the semi-monthly structure down to its major subs. Their electrical sub and drywall sub, who together represent $1.8M of the contract, had been billing Meridian monthly. Meridian revises those subcontracts to mirror the owner's billing windows: subs submit on the 8th and 23rd, two days before Meridian's own submissions, so sub invoices can be verified and rolled into the GC application without a scramble.

This matters for two reasons. First, it keeps Meridian's cost data current when they prepare each draw. Second, it gives the subs faster payment. Under Meridian's standard pay-when-paid clause, sub payment runs within 7 days of Meridian receiving owner funds. With twice-monthly owner payments, subs receive funds roughly every 15 to 16 days instead of every 30 to 35 days. That alone reduces the number of "where's my check" calls Meridian's office manager fields each month.

What Meridian Got Right, and One Thing They Missed

Meridian negotiated the draw schedule before signing. That is the single most important thing they did. Draw schedules written into the contract are far easier to enforce than verbal agreements made after mobilization.

They also built a clean schedule of values before the first billing, allocating costs across 22 line items tied to CSI MasterFormat divisions. That made splitting each month's billing into two halves straightforward because costs were tracked by division and phase, not lumped into broad buckets.

The one thing they missed: they did not negotiate a stored-materials billing right. In months 3 and 4, Meridian pre-purchased $310,000 in millwork and specialty glazing, paying the vendor 60% upfront for long-lead items. Because the contract did not explicitly allow billing for stored materials on or off site, those costs sat outside the draw schedule until the materials were installed. That created a short-term gap of about $186,000 that hit the line of credit hard. Negotiating a stored-materials provision, and tying it to vendor invoices and lien waivers, would have solved it. For projects with significant long-lead purchases, this clause belongs in the contract alongside the draw schedule.

Retainage tracking is the other piece to keep clean when billing twice monthly. With 10% held on every draw, retainage accumulates twice as fast in the accounting system. Dana used EZBilling's retainage tracking tools to keep a running balance by cost division, so forecasting the release at substantial completion was straightforward rather than a manual spreadsheet exercise.

Key Takeaways for Your Next Contract Negotiation

• Negotiate the draw schedule before execution. Once a contract is signed, owners rarely agree to change billing frequency mid-job.
• Frame the benefit to the owner. Smaller, more frequent applications are easier to certify than one large monthly billing.
• Align sub billing windows to your own. Require sub invoices two days before your owner submission date so costs are verified and included.
• Include stored-materials rights for any project with long-lead purchases. Pre-purchased materials can create significant cash gaps if the contract does not allow billing for them.
• Build a detailed schedule of values from day one. You cannot split a month's billing cleanly if your line items are too broad to attribute to a specific period of work.
• Model the interest savings before the negotiation. A concrete number gives you leverage with owners and helps justify the ask internally if your principals are skeptical.

Cash flow visibility starts with clean billing and cost data. EZBilling gives you both in one system built for construction.
