You had the piece sourced. You’d discussed it. And then you found out the client buys it themselves, maybe from a big-box retailer, maybe from the vendor directly, maybe just because they found it cheaper somewhere. Now you’re managing a project with an item you didn’t select, can’t stand behind, and didn’t earn any revenue on.
It happens more often than designers want to admit. And when it does, it tends to surface two problems at once: how to handle the immediate situation without damaging a relationship, and how to make sure it doesn’t happen again. Both are solvable. The order in which you solve them matters.
The Interior Design Community heard from a designer navigating exactly this situation: no contract language to cover it, a relationship to preserve, and a real question about how to move forward without it happening again. The responses ranged from practical scripts to specific contract clauses to one designer’s frank admission that she genuinely doesn’t care because her income model doesn’t depend on it.
All of it is worth reading.
Handle This One First, Then Fix the Contract
The most practical advice in the thread came from @lsi_workshop:
“First, I would deal with the situation at hand. It sounds like there isn’t anything in your contract to cover this, so have a friendly discussion with your client and tell them that this is not okay, you can’t let this happen again, and explain why in such a way that they think it’s to their own detriment to purchase on their own. Don’t make it about you losing money. Make it about them and the problems that can arise if you’re not coordinating things. The profit on one piece of furniture isn’t worth killing the relationship. Be friendly but firm. Then immediately go update your contract so it doesn’t happen again.”
@lsi_workshop
That sequence matters: handle the current situation relationally, frame the explanation around the client’s interests, and then close the gap in the contract before the next project.
The client’s actual risks when they buy independently are real and worth explaining:
- No control over lead time or delivery coordination
- If the item arrives damaged or incorrect, they own the problem
- The item may not integrate cleanly with the design concept
- Dimensions, clearances, and finish compatibility are their responsibility
The concrete risks show up in practice more than clients expect. @joseph.bellone shared a common scenario:
“I can’t tell you how many times they tell me they’ve bought material and after I find out the slab and quantity they purchased, I advise them that they’re short and need to buy more because they NEVER figure the right quantity correctly. Worse still is if the material is defective.”
@joseph.bellone
The message to a client isn’t “you violated our agreement and cost me money.” It’s “here’s what can go wrong when purchases aren’t coordinated, and here’s why I handle this for you.”
The framing of that conversation matters more than most designers expect. When you lead with what the client risked, not what you lost, the dynamic shifts. Most clients who buy independently aren’t trying to undermine the designer. They acted impulsively, thought they were being resourceful, or genuinely didn’t understand the scope of what they were bypassing.
Acknowledging that impulse before addressing the problem keeps the conversation from feeling like a reprimand. Something like: “I understand why you acted quickly on this. It’s a great piece, and you didn’t want to lose it. Here’s what I need you to know going forward.” That small adjustment tends to open the client up rather than put them on the defensive.
What Goes in the Contract: Real Language Designers Use
Designers in the thread varied in their specific approach. @patricklandrumdesign uses a fee structure paired with a built-in explanation:
“In my contract I specify a 43% fee on items selected without my involvement. But I explain when reviewing the contract that this is not a penalty; it’s because every piece must make sense in the entire concept. Stepping outside the concept affects the whole. I also let them know additional design fees may be incurred to integrate the piece into the plan. I’ve never had any pushback.”
@patricklandrumdesign
Others take a harder line on scope altogether. @kenneth_crawford_interiors_ describes what happened when a client tested it twice:
“In my contract it clearly states that they are not permitted to purchase anything for the project once the contract is signed. I had a client do that in the beginning and told them they violated the contract. They apologized and all was well, until toward the end they did it again on a huge ticket item. They got an email saying that I am terminating their contract.”
@kenneth_crawford_interiors_
That escalation, from warning to termination, is consistent with a firm contract and clear communication. The first violation got a warning. The second, on a major item, ended the relationship.
What the different approaches have in common: they’re defined in writing before the project begins, explained to the client during contract review, and connected to a coherent design rationale rather than presented as purely punitive.
Across the community, fees ranged from 15% on the lower end to 43% on the higher end, reflecting real differences in how designers structure their income and position their services. A designer whose business depends heavily on procurement markup may need a higher fee because the financial stakes are real. A designer in a more cost-sensitive market may set a lower threshold to avoid making the clause feel adversarial. What matters less is the exact number. What matters more is that it’s in writing, explained at contract signing, and grounded in a clear rationale. For the specific language that holds up in practice, the IDC post Essential Interior Design Contract Clauses to Protect Your Business covers the broader contract framework worth having in place before any of these conversations become necessary. Professional organizations like ASID also offer business practice resources and contract guidance for designers building or updating their agreements.
The Designer Who Doesn’t Care: Why Her Model Makes That Work
“Client is responsible for everything regarding this item. If something goes wrong with it, will I be nice and give a few talking points for their call with the furniture provider? Yes. Will I call for them? No, unless they pay my full hourly rate. Buy through me, don’t buy through me. I honestly don’t care. Design time is the bulk of my income because I know clients want to purchase on their own. I don’t have time to be petty about it.”
@lanotthecity
This is a coherent position for a designer whose business model is primarily design fee-driven rather than procurement-driven. If your income doesn’t depend heavily on product markup, clients buying on their own is a nuisance, not a revenue threat.
The business model question is worth examining honestly. If procurement revenue is a significant portion of your income, protecting it contractually is essential. If it’s a minor line item, the emotional energy required to enforce procurement control may not be worth it. Know which situation you’re in before deciding how hard to enforce.
Why Clients Do This, and How to Get Ahead of It
Clients rarely go around a designer out of malice. More often, something specific triggered the purchase: they found the item cheaper somewhere, they saw it in a store and acted on impulse, they didn’t fully understand what the designer’s coordination role actually covers, or they assumed the designer would be fine with it. Most of those reasons come back to a gap in expectations that could have been closed before the project started.
At contract review, walking clients through the procurement process explicitly, not just the clause, but what it means in practice, changes how they receive it. How items are sourced. Why lead time coordination matters. What happens when something arrives damaged? What the designer’s involvement means for their project warranty. When clients understand those details, the clause no longer feels like a restriction and becomes protection.
Designers who report zero friction around procurement clauses tend to say the same thing: they talk through the rationale rather than letting the clause speak for itself. @patricklandrumdesign is a good example. He specifies a 43% fee and has never had pushback, because he frames the clause around design concept integrity rather than revenue protection.
There’s also a simpler version of this conversation that can happen early, even casually: “Some clients ask about sourcing items on their own. You can, but I want you to understand what falls outside my scope when that happens.” That one sentence, said at the right time, tends to prevent most of the situations this post is about.

The Items You Can’t Stand Behind
There’s a separate issue that runs alongside the revenue conversation: what happens to the design when a client buys something that doesn’t work? @margonathansoninteriors named it directly:
“If they’ve purchased something that doesn’t work with the already specified but not procured items, I tell them it will be a re-design, and they’ll be paying more in design fees.”
@margonathansoninteriors
The key is being clear with the client that items they sourced independently are outside the designer’s responsibility. If it doesn’t fit, if it arrives damaged, if it disrupts the design cohesion, those are the client’s problems to solve. That clarity protects the project and the relationship, because it sets expectations before something goes wrong rather than after.
Documenting that clearly in writing protects you from being held accountable for outcomes you didn’t control. A brief email works: “As we discussed, this item falls outside my project management scope. I’m happy to advise on integration, but coordination, delivery, and any issues with this piece will be handled directly between you and the vendor.” Short, professional, and on record.
The Contract Language to Add Before Your Next Project
If your current contract doesn’t address client purchases, here’s what to include before the next engagement:
- A clear statement that all procurement for the project is coordinated through the designer
- A fee or percentage applied to items the client sources independently, framed as a coordination and integration charge
- Language stating that the designer is not responsible for delivery, defects, or design integration issues on client-sourced items
- A clause that additional design fees apply if a client-sourced item requires redesign work
Present these clauses during your contract review, not in fine print. @patricklandrumdesign walked through the rationale with every client and had zero pushback. Most clients, when they understand that the clause exists to protect the integrity of the design rather than to extract money, accept it without discussion.
The designers who navigate this situation with the least friction aren’t necessarily the ones with the most aggressive contract language. They’re the ones who treat procurement scope as something they explain once, clearly, before the project begins. That conversation is part of the client relationship work, not separate from it.
