Interior Design Invoice Template - South Africa

Yes, interior design services are subject to the 15% VAT in South Africa. You must add VAT to all design fees, consultations, and service charges if you're VAT-registered. This applies to design consultations, space planning, colour scheme development, and project management hours. VAT should be calculated on the subtotal before the final invoice amount. If your client is a registered VAT vendor, they can claim the input VAT back, so include your VAT registration number clearly on the invoice.

Break your invoice into distinct line items for each service type. Common categories include initial consultation, space planning and layout design, furniture selection and procurement, lighting design, custom treatments, and project management. This transparency helps clients understand where their money goes and justifies your fees. Separate hourly services from fixed-price services clearly. Listing services individually also provides audit clarity and helps establish your professional standing in the South African market.

Most South African interior designers charge either a fixed consultation fee (typically R1,500–R3,500) or an hourly rate (R400–R800 per hour). A fixed fee is simpler for clients and easier to quote upfront. Consider whether the consultation is refundable toward future design work—many designers offset the consultation cost if the client proceeds with the full project. Clearly state the consultation scope: how long it lasts, what's included, and whether travel is additional. This prevents scope creep and sets professional expectations.

You can charge for procurement services in two ways: as a flat service fee for sourcing and selection, or as a percentage markup on furniture costs (typically 15–25%). State clearly on the invoice whether furniture prices shown are net costs, your retail prices, or margin-inclusive totals. Separate the procurement service line item from furniture costs to maintain transparency. Include supplier names if relevant. If you're ordering furniture on behalf of clients, specify whether they're purchasing directly through you or if you're billing a sourcing service only.

Standard terms in South Africa are Net 30 or Net 14 for design services. For larger projects, many designers request a 50% upfront deposit to begin work, with the balance due on completion. Some require staged payments aligned with project phases—for example, payment after concept approval, again at design completion, and final payment on project handover. Clearly state your payment terms and any late payment interest (typically 1–2% monthly). Include your banking details prominently and specify acceptable payment methods: EFT, card, or cheque.

Include a limited number of revisions in your initial design fee—typically two or three rounds. After that, charge for additional revisions separately, either at an hourly rate or as a fixed service charge per revision round (R500–R1,500 depending on complexity). Document your revision policy in writing before starting work. On the invoice, clearly state whether revision charges apply or are included. If a client requests significant scope changes, issue a change order or addendum invoice rather than absorbing the cost. This prevents undercharging and manages expectations.

Include your business name, VAT registration number, physical and email address, and phone number. List the invoice number, date, and payment due date. Show the client's full details and project reference if applicable. Itemize each service with quantity, rate, and amount. Include any applicable discounts or deposits already paid. Add VAT clearly, showing subtotal, VAT amount, and final total. Include your banking details, payment instructions, and terms. Adding a brief project description or reference helps clients match the invoice to their project and improves record-keeping.

The template structure is similar, but commercial invoices often require a project code, purchase order reference, or department contact. Commercial clients typically expect formal payment terms (Net 30–60) and may require VAT invoices with strict compliance. Residential invoices are often simpler and may allow shorter payment windows. Commercial projects usually involve larger fees and more itemization. Consider adding a project code or reference line for commercial work to simplify their accounting. Some commercial clients require specific invoice formatting or sign-off procedures, so clarify requirements upfront before issuing your invoice.
