You work with custom specs, heavy materials, and tight deadlines — and your invoice needs to reflect that complexity. It should clearly separate charges for templating, fabrication, and installation, while breaking out material costs for granite, quartz, marble, or other surfaces. Details like edge finishes, sink cutouts, and backsplash additions should be itemized, and the invoice should accommodate partial payments or deposits. Providing clear, permanent documentation helps keep clients and contractors aligned. With homeowners, designers, and general contractors all in the mix, transparent billing is key to avoiding disputes and keeping projects on track.
