Progress Billing Best Practices in Precast Manufacturing

Progress billing is the lifeblood of cash flow management in precast manufacturing. With production cycles spanning weeks or months and significant upfront costs, the ability to bill customers at key milestones can make the difference between healthy growth and constant cash struggles.

Why Progress Billing Matters in Precast

Unlike retail businesses that collect payment at the point of sale, precast manufacturers face a fundamental cash flow challenge: you invest heavily in materials, labor, and overhead weeks before final payment arrives. Without progress billing, you're essentially providing free financing to your customers.

Consider a typical $200,000 precast project:

Progress billing transforms your working capital requirements from funding entire projects to bridging short-term gaps between milestones.

Establishing Billing Milestones

The key to effective progress billing is defining clear, measurable milestones that align with your actual costs and production flow. Here are the most common and effective milestone structures:

Standard Milestone Structures

Creating Verifiable Milestones

The best billing milestones are objective and easily verifiable. Avoid vague terms like "substantial completion" or "50% complete." Instead, use concrete triggers:

• Shop drawings approved - Engineering complete, production ready
• Steel reinforcement placed in molds - Photographic proof
• Concrete poured and curing - Timestamp verification
• Pieces removed from molds - Production milestone reached
• Quality inspection passed - Third-party or internal QC sign-off
• Bill of lading signed - Delivery confirmed
• Installation complete - Site photos or GC confirmation

Negotiating Progress Billing Terms

Many general contractors default to back-loaded payment schedules that favor their cash flow, not yours. You need to proactively negotiate better terms upfront.

Effective Negotiation Strategies

When to Be Flexible

Not every situation warrants rigid adherence to your preferred billing schedule. Consider relaxing terms for:

• Long-standing customers with perfect payment history - Reward loyalty with better terms
• Public works projects - Government contracts often have fixed payment structures
• Large contractors with strong credit - Financial stability reduces your risk
• Repeat business opportunities - Win the relationship, optimize terms later

However, always require some deposit (minimum 15-20%) and shorten payment terms where you relax milestones.

Automating the Billing Process

Manual billing processes cost you money in three ways: delayed invoicing, billing errors, and administrative overhead. Modern ERP systems can automate progress billing from milestone tracking to invoice generation.

Key Automation Features

Documentation Best Practices

Strong documentation prevents payment disputes and accelerates approval. For each billing milestone, provide:

• Photographic evidence - Timestamped photos showing work completed
• Production reports - Piece counts, pour dates, cure completion
• Quality certifications - Test results, inspection reports
• Shipping documentation - BOLs, delivery receipts, GPS tracking
• Time tracking - Labor hours invested (for cost-plus contracts)

The easier you make it for contractors to verify and approve your invoices, the faster you'll get paid.

Handling Common Billing Challenges

Delayed Milestone Approvals

General contractors sometimes delay approving billing milestones to manage their own cash flow. Combat this with:

Disputed Billing Amounts

Occasionally contractors will dispute a billing milestone or amount. Minimize disputes by:

• Including detailed milestone definitions in your contract
• Providing comprehensive documentation with every invoice
• Proactively communicating when milestones are approaching
• Building in small contingency buffers for minor variations

Change Order Billing

Scope changes are common in construction. Establish clear change order procedures:

• Written approval required - Never proceed without signed change order
• Payment terms on change order - Often 50% upfront, 50% on completion
• Separate billing line items - Don't bury changes in original billing schedule
• Expedited payment for rush changes - Net 15 instead of net 30 for emergency work

Implementation Roadmap

Transitioning to effective progress billing doesn't happen overnight. Follow this phased approach:

The Bottom Line

Effective progress billing fundamentally changes your cash flow dynamics. Instead of financing entire projects for months, you're bridging short gaps of weeks. Instead of scrambling to make payroll, you have predictable cash inflows aligned with your production cycle.

The manufacturers who master progress billing grow faster, stress less, and maintain healthier relationships with suppliers and employees. Those who don't find themselves perpetually cash-strapped despite winning profitable work.

Start with your next new contract. Include clear milestone billing terms upfront. Document completion thoroughly. Invoice immediately. You'll see the difference in your bank account within weeks.
