How Progress Billing Works
The process starts with a contract that defines the total project price, billing milestones, payment percentages, supporting documentation, and payment terms. The project team records progress against each milestone, and finance verifies that the agreed billing conditions have been met before issuing an invoice.
A furniture installation contract might use the following milestones:
- Contract award: Invoice an agreed deposit after the customer signs the contract.
- Design approval: Bill the next portion after layouts, finishes, and furniture specifications are approved.
- Procurement and manufacturing: Invoice when materials are ordered or customized furniture reaches the contracted production milestone.
- Delivery: Bill the portion associated with delivery to the project site.
- Installation and acceptance: Invoice the remaining amount after installation, inspection, or customer sign-off, according to contract terms.
Each milestone should have clear completion criteria. For example, a procurement milestone may require supplier order confirmation, while an installation milestone may require a signed completion record. This evidence gives finance a consistent basis for preparing invoices and responding to customer questions.
Calculating Progress Billing Amounts
Progress billing commonly uses a fixed percentage of the contract value or an agreed amount for each milestone. A basic calculation is:
Milestone billing amount = Total contract value × Milestone percentage
Assume a furniture project has a contract value of $120,000 and the agreed billing schedule allocates 20% to contract award, 30% to manufacturing completion, 40% to delivery and installation, and 10% to final acceptance.
- Contract award: $120,000 × 20% = $24,000.
- Manufacturing completion: $120,000 × 30% = $36,000.
- Delivery and installation: $120,000 × 40% = $48,000.
- Final acceptance: $120,000 × 10% = $12,000.
The four milestones total $120,000, matching the contract value before taxes, approved change orders, credits, or other adjustments. If the first two invoices have been issued and paid, the project has billed $60,000, leaving $60,000 scheduled for the remaining milestones. Businesses should distinguish amounts billed from amounts collected because an issued invoice does not mean the customer has paid.
Invoices, Approvals, and Financial Records
A consistent Progress Billing procedure defines when work qualifies for billing and which documents must support each invoice. The Billing System should maintain the customer, contract, milestone, amount, invoice date, due date, and payment status. Each Billing Document should clearly identify the milestone covered, the amount requested, and any relevant contract reference.
Invoice preparation should also include validation of customer details, contract rates, approved changes, tax treatment, and milestone evidence. Invoice software can help capture and validate billing information, match records, support general ledger coding, and route invoices through approval before posting. Finance should ensure that the invoiced amount follows the contract and applicable revenue-recognition policy; billing milestones and accounting revenue recognition are related but not necessarily identical.
Managing Cash Flow and Project Commitments
Progress billing helps a furniture business plan cash needs across procurement, manufacturing, delivery, and installation. When milestone invoices are issued and collected on schedule, incoming cash can help fund supplier payments, freight, labor, and site preparation. Finance teams should forecast expected collections against the timing of project expenditures rather than treating all billed amounts as immediately available cash.
Customer payment follow-ups and collections processes help manage overdue milestone invoices. AR Automation Software can support invoice follow-ups and payment matching, while cash application helps allocate customer receipts to the correct invoice. Together, these processes improve receivables visibility and help teams identify outstanding balances that may affect project funding.
For a broader view of how billing connects with customer orders, invoicing, and receivables, Sync Sales to Cash provides context on aligning sales and billing workflows. Businesses can also use the Hyperbots Platform and its integrations with finance systems to connect billing information with relevant ERP records, where supported by their configuration.
Best Practices for Furniture Project Billing
Establish billing milestones before work begins and confirm that the customer accepts the associated evidence requirements. Coordinate sales, project management, procurement, installation, and finance so that each team understands what must happen before an invoice can be issued.
Use a project-level billing schedule to monitor planned milestones, actual completion dates, invoices issued, receipts collected, and the remaining contract balance. If scope or pricing changes, update the approved contract value and billing schedule before calculating subsequent invoices. For purchasing visibility, keep the related purchase order and supplier commitments aligned with the project schedule, particularly when customer deposits are expected to fund customized materials.
Review overdue invoices, disputed milestones, unbilled completed work, and upcoming supplier obligations regularly. These checks help managers identify collection delays early, maintain reliable project forecasts, and make informed decisions about scheduling resources across multiple furniture projects.
Summary
Progress billing for furniture projects divides contract payments into agreed stages tied to project milestones. By defining completion criteria, calculating each installment accurately, documenting invoice support, and monitoring collections separately from billings, businesses can strengthen cash flow planning and maintain transparent customer accounts throughout procurement, production, delivery, and installation.
