Residential Spatial Planning & Concept Interior Styling
Deliverable Scope Management
Residential design contracts cover client lifestyle discovery, room spatial layouts, bespoke color schemes, surface material specifications, and high-resolution 3D photorealistic perspective visualizations. When operating in France, clarify statutory deliverable milestones and TVA obligations upfront.
Billing Structure & Fee Models
Bill per design room package or flat project fee staged across milestone phases: 50% mobilization deposit, 30% schematic design approval, and 20% final design pack handoff. Standard commercial settlement in France operates under Net 30 terms with statutory late compensation governed by Key ECB refinancing rate plus 10 percentage points, plus statutory €40 recovery indemnity.
Protective Legal Clauses & IP Rights
State that design drawings represent artistic concepts requiring licensed contractor verification, limit design iterations to two rounds, and retain copyright for portfolio showcase. Under France commercial law, contracts should clearly define tax point dates and liability caps.
Allowable Business Expenses & Tax Write-Offs
Deduct CAD drawing software licenses, 3D rendering cloud engines, fabric and wallpaper swatch decks, digital measuring lasers, and professional design society subscriptions. Maintain all itemized purchase receipts for at least 10 years to satisfy Direction Générale des Finances Publiques audit mandates.
Timesheet & Milestone Logging Protocol
Organize design documentation by spatial phases: client brief notes, concept mood boards, revised CAD layouts, and final client sign-off certificates. For registered interior designers in France, digital PDF records are classified as CONDITIONAL for accounting source verification.
Invoicing Tips & Best Practices for Interior Designers
Upfront Deposits & Retainers: Require an upfront design deposit of 50% prior to preparing conceptual mood boards and technical drawings. FF&E furniture purchases must be 100% pre-funded by the client before orders are placed with manufacturers.
Common Invoicing Pitfalls:
- Purchasing bespoke furniture or fixtures on corporate credit cards without 100% advance client reimbursement.
- Allowing unlimited design revisions without specifying baseline concept iteration thresholds.
- Accepting structural architectural liability for load-bearing modifications without licensed engineering sign-off.
- Failing to disclose trade discount sharing or purchasing commissions transparently in contract agreements.
Cross-Border Considerations: Cross-border interior design services for immovable property are commonly taxed at the jurisdiction where the real estate is physically situated. Confirm local property place-of-supply rules.

Payment Pacing: Commercial credit agreements standardly require settlement within 30 calendar days. Late interest compensation: Key ECB refinancing rate plus 10 percentage points, plus statutory €40 recovery indemnity.
Statutory Archive Requirements: Official regulations demand archival storage of all commercial bills for at least 10 years.
