Carpentry Invoicing: A 2026 Guide
Clear, detailed invoicing protects your carpentry business and builds client confidence. Here is how to structure your invoices for maximum professionalism.
Detailed Materials Breakdown
Clients want to know where their money goes. List every material with specifics: "White Oak - 4/4 x 8' boards x 12 @ $14.50/board ft" rather than "Wood - $500." Include hardware (hinges, screws, drawer slides), adhesives, finishes, and sandpaper. This level of detail prevents disputes and demonstrates your transparency.
Labor Rate Structures
Carpenters typically bill using one of three structures: hourly rate (best for repair work and small jobs), per-project flat fee (best for custom builds with defined scope), or cost-plus (materials at cost plus a percentage markup, common in renovation work). Choose the model that fits the job and state it clearly on your invoice.
Change Order Documentation
Custom carpentry projects frequently involve design changes. Handle them properly:
- Get written approval for any scope change before starting additional work.
- Document change orders with the additional materials and labor required.
- Invoice change orders as separate, clearly labeled line items.
