When should I use fixed-fee vs cost-plus on FF&E projects?

If you run a design studio, you know how FF&E procurement can quietly eat into your margin. Most of us have a default pricing method—usually the one we learned as a junior designer. But choosing between a fixed-fee and a cost-plus model is a strategic decision. It affects your profit, your client relationships, and the risk you carry on a project.

See budget and profitability signals without manual rollups. There is no single right answer. The best approach depends on the project, the client, and your own studio's comfort with risk.

The fixed-fee model—predictability for both sides

Apply markup guidance tied to project context. With a fixed fee, the client gets a clear, all-in price for FF&E. That can be a strong selling point—especially for clients who need budget certainty. They know the total cost for every item before they sign off.

The trade-off is that you carry all the risk. You have to be confident in your cost estimates. If a vendor price goes up, shipping gets delayed, or a piece arrives damaged—that cost comes directly out of your fee.

This model works best for projects with a tight scope and few unknowns. It's a good fit for jobs with mostly off-the-shelf items from vendors you trust.

A fixed-fee example

Let's say you're specifying a custom sofa for a client. You need to build a single, fixed price that covers the item and your fee.

• Sofa Trade Cost from "Heirloom Upholstery": $5,000
• Estimated Freight (based on past orders): $500
• White-Glove Receiving & Delivery: $250
• Your Estimated Landed Cost: $5,750

Now, you add your procurement fee. Let's say you aim for a 25% margin on your cost.

• Your Procurement Fee: $5,750 x 0.25 = $1,437.50
• Total Fixed Price to Client: $5,750 + $1,437.50 = $7,187.50

The risk is clear. If that freight quote comes back at $850 instead of $500, that unexpected $350 is your loss. Your fee shrinks from $1,437.50 to $1,087.50, cutting your margin by nearly 25%.

The cost-plus model—flexibility and margin protection

The cost-plus model is more common in residential design for a reason. You charge the client your actual net cost for an item, plus a percentage markup. That markup is your procurement fee.

This approach gives your studio flexibility and protects your margin. If a vendor’s freight costs go up, that increase is passed to the client. Your markup is applied to the new, higher total—so your fee scales with the actual landed cost.

The challenge is client communication. You have to be transparent about your costs and how your fee is calculated. It comes down to building trust and showing the work your fee covers—the sourcing, negotiating, purchasing, and tracking.

A cost-plus example

Let's use the same sofa, but with a cost-plus model and a 30% markup.

• Sofa Trade Cost: $5,000
• Actual Freight Cost: $850
• White-Glove Receiving & Delivery: $250
• Your Actual Landed Cost: $6,100

You present this landed cost to the client and apply your markup.

• Your Procurement Fee (30%): $6,100 x 0.30 = $1,830
• Total Price to Client: $6,100 + $1,830 = $7,930

In this scenario, the unexpected freight increase is covered, and your fee adjusts accordingly.

Hybrid approaches—finding a middle ground

You don’t have to stick to just one model. Many studios I know use a hybrid approach to balance predictability with flexibility.

A common strategy is to charge a fixed fee for your design services—the creative work, drawings, and presentations. Then you use a cost-plus model for all FF&E procurement. This gives the client a predictable cost for your design time, while the procurement budget remains flexible.

For very large or phased projects, you might even use different models for different parts of the job. Perhaps a fixed fee for standard items in guest rooms and a cost-plus model for the highly custom furniture in the main lobby.

How to choose

So, how do you choose? It comes down to a few key factors on each project.

• Project complexity. Is this a straightforward furnishing project with standard items, or a complex custom build with many variables? The more custom and complex, the stronger the case for cost-plus.
• Scope clarity. How well-defined is the scope from the start? If the client is decisive and the vision is clear, fixed-fee is a safer bet. If they are exploratory and likely to make changes, cost-plus protects you when the scope changes.
• Client relationship. Trust is everything. A long-time client who understands the value you bring may be perfectly comfortable with a cost-plus model. A new client might prefer the certainty of a fixed fee for their first project with you.
• Your risk tolerance. How much financial risk is your studio prepared to take on? Fixed-fee pricing puts the risk on you. Cost-plus shares it with the client.

Protecting your margin—no matter the model

No matter which model you choose, your profit depends on tracking everything. Most studios already track specs in a spreadsheet or manage approvals through email threads. The details matter.

Unexpected shipping fees, backorders, and client changes can quietly eat your margin if you aren't watching closely. You need a clear view of every item’s landed cost, approval status, and payment schedule. Otherwise, you're pricing in the dark.

Price with clarity. Install with confidence.

The goal is to price your work in a way that’s fair to your clients and profitable for your studio. So you can spend more time on design decisions and less on chasing down numbers. Alcove gives your team one organized system for specs, quotes, approvals, POs, order status, and financials—so you're no longer digging through emails, spreadsheets, or vendor threads for answers.

Seeing how every spec, cost, and markup decision affects your project’s bottom line is powerful. We built Alcove to give you that clarity from the first spec to the final install. See how we do it at alcove.co.

Questions I get asked

What’s the biggest risk of fixed-fee FF&E pricing?

The biggest risk is scope creep and surprise costs. If a client changes their mind, a vendor raises prices, or a long lead time forces you to pay for expedited shipping—your profit margin can disappear. Fixed-fee pricing requires very accurate upfront estimates and a solid change order process.

How do I make cost-plus pricing transparent for clients?

Transparency comes down to clear communication from the start. Explain how your percentage is applied and what it covers. Then, provide regular, detailed reports of the actual costs and your markup. Alcove’s client portal, for example, lets them see approved items and their costs in one place—which builds trust and prevents surprises.

Can I switch pricing models mid-project?

I wouldn’t recommend it. Switching models mid-project can damage client trust. If a project's scope changes so much that your original agreement doesn't work anymore, it’s better to have an honest conversation. Outline the new scope and costs, and get a formal sign-off on a revised plan—don't just change the pricing model.

What’s a typical markup percentage for cost-plus FF&E?

It varies a lot depending on your studio's overhead, the project's complexity, and your local market. Most studios I have worked with apply a markup between 15–30% on trade costs. That percentage needs to cover your time, admin costs, project management, and still leave a healthy profit. Designed spaces require clear communication and coordination.
