Painting Invoice Template: Interior vs Exterior, Per-Room Pricing, Preparation & Staged Billing

Painting jobs vary widely—from a single room refresh to a full exterior repaint. How you structure the invoice affects clarity, cash flow, and client trust. Interior and exterior work have different pricing models; preparation often takes as long as the paint itself. Per-room pricing suits residential; per-square-metre suits commercial or large areas. This guide covers pricing structures, preparation work, paint supply and markup, colour consultation, and staged billing for large jobs, with example breakdowns.

Interior vs Exterior: Different Pricing Models

Interior �?Often quoted per room or per wall. Ceilings, trim, and feature walls add complexity. High-traffic areas (kitchens, bathrooms) may attract a premium. Per-room is simple for clients to understand: "Living room �?walls and ceiling �?$450."

Exterior �?Typically per square metre or per lineal metre for fascia and trim. Access (scaffolding, ladders) and surface condition affect the rate. Two-storey work costs more than single-storey. Weather delays are common—include a clause in your terms.

Per-Room vs Per-Square-Metre

Per-room �?Best for residential. Clients think in rooms. Example: $350�?600 per room depending on size, ceiling height, and trim. Specify what's included: "Walls, ceiling, one coat undercoat, two coats finish."

Per-square-metre �?Best for open-plan, commercial, or large areas. Example: $25�?45/m² for walls and ceiling, depending on finish and access. Use when room-based pricing doesn't fit.

For a detailed breakdown of how to structure painting quotes, see our painting job quote example. The invoice should mirror the accepted quote.

Preparation Work: Don't Underquote It

Preparation—filling, sanding, masking, washing—often takes 40�?0% of job time. Itemise it:

Item	Qty	Unit	Total
Filling and sanding (walls)	1	$180	$180
Masking and protection	1	$95	$95
Wash down (exterior)	1	$120	$120

If you bundle prep into labour, state it: "Labour includes filling, sanding, and masking." Otherwise clients may assume prep is included and dispute the line.

Paint Supply and Markup

Supply at cost �?Some painters charge paint at cost plus a small handling fee. Transparent but no margin on materials.

Markup �?15�?5% on paint is common. State it: "Paint supplied at cost + 20%." Or show it as a line: "Paint and materials �?$420 (includes 20% handling)."

Customer supplies �?If the client buys paint, bill labour only. Specify in your quote: "Quote based on customer-supplied paint. Supply by us: add $X."

Colour Consultation and Staged Billing

Colour consultation �?If you charge for colour advice, list it: "Colour consultation �?1 hr �?$85." Or absorb it for larger jobs.

Staged billing for large jobs �?For jobs over $5,000, split into deposit, progress, and final. Example for a $12,000 interior repaint:

Stage	Amount	Trigger
Deposit	$3,600 (30%)	On signing
Progress	$4,800 (40%)	Prep complete, first coat on
Final	$3,600 (30%)	Job complete, touch-ups done

Invoice each stage separately. Reference the quote number. For structuring deposits and milestones, see how to quote for a job.

Example Breakdown

Interior �?Single Room

Item	Qty	Unit	Total
Prep (fill, sand, mask)	1	$120	$120
Undercoat	1	$85	$85

Deposit (30% of $8,500)	$2,550

Stage 2 �?Progress

Item	Qty	Unit	Total
Wash, scrape, fill	1	$480	$480
Primer (exposed areas)	1	$220	$220
Two coats exterior paint	85 m²	$42/m²	$3,570
Paint supply	1	$680	$680
Progress total			$4,950

Stage 3 �?Final

Item	Amount
Balance (trim, touch-ups, cleanup)	$1,000

Always send a quote before starting. Match the invoice to the accepted quote. For more on structuring painting quotes and invoices, see painting job quote example and how to quote for a job.

Summary

A painting invoice should distinguish interior from exterior, use per-room or per-square-metre pricing as appropriate, and itemise preparation work. Show paint supply and any markup clearly. For large jobs, use staged billing—deposit, progress, final—and reference the quote. Clear line items and staged payments reduce disputes and improve cash flow.
