Invoice clients for architectural design, planning applications, and construction administration. Get paid on time with Tidybill.
An architect invoice documents fees for the professional design and management services provided during a building or renovation project. Architectural services are typically structured across defined RIBA stages (or equivalent): from initial feasibility and briefing through concept design, planning application, technical design, construction management, and project close-out. Because architecture projects span months or years and involve significant liability, invoicing is closely tied to project stages. Architects charge either a percentage of the construction cost, a lump sum, an hourly rate, or a combination depending on project type and client agreement. Detailed, stage-based invoices protect the architect's fees and provide the client with a clear audit trail of services rendered.
| Service | Typical Rate | Unit |
|---|---|---|
| Feasibility Study & Initial Briefing | 1-2% | of construction cost |
| Concept Design (RIBA Stage 2) | 2-3% | of construction cost |
| Planning Application Preparation | £800 - £3,000 | per application |
| Technical Design & Drawings (RIBA Stage 4) | 4-6% | of construction cost |
| Construction Administration | 2-4% | of construction cost |
| Disbursements (planning fees, prints, surveys) | At cost | per project |
Invoice at the end of each RIBA stage or at agreed monthly intervals for construction-stage work. Include a clear description of which stage has been completed and what services were delivered. For hourly rate commissions (common for smaller residential projects), submit monthly invoices with a timesheet attachment showing hours worked per day. Disbursements should be invoiced at actual cost with receipts available. VAT at 20% applies to all UK architectural services. Net 14 to Net 30 depending on client agreement.
