Interior Designer Invoice Template: Free + What to Include

Interior design invoicing is uniquely complex β€” you're billing for design time, procurement, trade discounts, and physical goods all on the same project. Here's exactly what to include and how to structure it.

What Makes Interior Design Invoicing Unique

Unlike a web designer who invoices for time and deliverables, an interior designer may invoice for multiple revenue streams on a single project:

Design fee

Your professional fee for design work β€” concept, space planning, drawings, supplier coordination. Typically flat fee or hourly.

Furniture, fixtures & equipment (FF&E) procurement

You purchase items on behalf of the client. You may invoice at trade cost + markup, or at retail price (keeping the trade discount as profit).

Procurement management fee

A fee for managing the procurement process β€” typically 15–30% on top of item costs, separate from the design fee.

Contractor coordination fee

For managing tradespeople (painters, carpenters, plumbers) β€” usually 10–15% of total contractor costs.

Trade discounts β€” to pass on or not?

As a trade buyer, you typically receive 30–50% off retail prices. Whether you pass this to clients or keep it as profit should be agreed upfront and stated in your letter of agreement.

Interior Design Invoice Fields

A professional interior design invoice needs more fields than a typical freelance invoice:

Getting Your Interior Design Invoices Paid on Time

Interior design invoices can be large β€” €5,000–€50,000+ β€” which makes late payments very painful. Protect yourself:

1.Never release FF&E orders until the procurement advance is paid
2.Hold final design files (CAD drawings, specification sheets) until final payment received
3.Include a retention clause for large commercial projects (5–10% held back 30 days after completion)
4.Use milestone-based invoicing to spread cashflow risk
5.Automate payment reminders β€” most late payments are forgotten, not malicious

Frequently Asked Questions

How do interior designers typically charge for their services?

Most use a combination: hourly or flat fee for design work, plus cost-plus markup (15–30%) on FF&E procurement. The exact model should be agreed in writing before starting.

Should I show my trade discount on the invoice?

Only if you've agreed to pass it on. If you're using cost-plus pricing, show the client your cost (what you paid) plus your markup. Full transparency prevents disputes.

Do interior designers charge VAT on furniture they buy for clients?

VAT rules on goods and services vary by country. In most EU countries, you charge VAT on your design fee and on goods you supply. Consult your accountant.

What happens if a client doesn't pay before I've ordered furniture?

This is why procurement advances exist. Do not order FF&E without the advance paid β€” you become personally liable for the order. Make this clear in your letter of engagement.

How do I invoice for an ongoing interior design retainer?

Monthly retainer invoices should specify: service period, included hours, any additional hours at [rate]/hr, and what's covered (project management, supplier liaison). Chaser can automate monthly retainer invoicing.
