How do contractors handle progress payments?
Why Progress Payment Fundamentals Matter
Progress payments are a cornerstone of construction financing, allowing contractors to maintain cash flow while completing work over extended timelines. Rather than waiting until project completion for full payment, progress payments tie invoicing to completed milestones or time periods. Industry norms typically involve 3-5 payment stages spread across a project's duration, with the final 5-10% retained until substantial completion. This approach protects both parties: contractors secure regular income to cover labor and materials, while clients ensure quality work before releasing full payment.
Common Milestone-Based Payment Structures
Milestone-based payments align invoicing with tangible project achievements. Common milestones include design completion, permit approval, foundation completion, framing completion, rough-in work, and final inspection. Each milestone represents clear deliverables that clients can verify before releasing payment. This method works exceptionally well for renovation and custom construction projects where progress is visually evident. Define milestones upfront in your proposal so clients understand exactly when to expect invoices and what work must be completed to trigger payment. Clear milestone definitions prevent disputes and clarify payment obligations.
Payment Splits by Project Type
Different project types require different payment structures. Residential renovation projects typically use 50% down, 40% upon substantial completion, and 10% retention until final walkthrough. Commercial construction often splits payments into 5-6 equal installments (15-20% each) tied to construction phases. Smaller service-based projects might use 30% upfront, 40% upon completion of major scope items, and 30% at final completion. Design and engineering work typically follows 30% upon contract signing, 35% at milestone checkpoints, and 35% upon delivery. Align your payment terms to industry standards within your sector while accounting for your specific cash flow needs.
Time-Based vs. Percentage-of-Completion Payments
Beyond milestones, contractors often use time-based or percentage-of-completion payment models. Monthly payment schedules are common for long-term projects, invoicing clients on fixed dates regardless of milestone achievement. Percentage-of-completion ties payments to the percentage of total budget spent—when 25% of budget is consumed, invoice for 25% of contract value. This method requires detailed cost tracking but aligns payments with actual resource consumption. Many contractors combine approaches: use monthly invoicing for recurring labor costs while reserving milestone-based payments for major deliverables and equipment purchases.
Retention and Final Payment Considerations
Industry standard retention policies hold back 5-10% of progress payments until final project completion and customer approval. This final retention protects clients against undiscovered defects and incentivizes contractors to complete all work promptly. Document retention policies clearly in your initial proposal so clients understand the payment structure. Set a specific date for final payment tied to substantial completion, not indefinite retention. Many jurisdictions have mechanics lien rights that limit how long retention can be held—typically 30-60 days after final completion. Build final payment timelines into your contracts to maintain cash flow predictability.
Automating Payment Schedules with Erro
Managing multiple progress payments across dozens of active projects quickly becomes overwhelming when handled manually through spreadsheets and emails. Erro's construction management platform automates the entire payment schedule workflow. Define your payment milestones upfront in proposals—specify exact deliverables, payment amounts, and due dates. Erro automatically reminds clients at customizable intervals before the due date.
Scheduling Milestones and Creating Proposal Payment Terms
Within Erro, create reusable payment templates for each project type. Save your standard 50-40-10 residential structure, your 5-phase commercial split, or your monthly recurring invoice schedule as project templates. When creating a new proposal, select the appropriate template and Erro populates payment milestones with pre-configured amounts and dates. Customize individual projects by adjusting milestone names, payment percentages, and due dates—changes instantly update the proposal document. Clients see a clear payment schedule in the proposal, reducing confusion and improving approval rates.
Automated Payment Reminders and Follow-Up
Once a proposal is accepted and work begins, Erro invoices help automate payment reminders. If payments are overdue, Erro sends follow-up reminders. Clients receive consistent, professional communication without your team manually sending reminder emails. The invoice dashboard provides real-time visibility into payment status across all active projects. See which invoices are outstanding, overdue, or scheduled for future payment.
