Deposit structure is not a client-experience detail. It is a cash flow and risk decision that determines whether you can pay your vendors on time, survive a client who disappears mid-project, and actually profit from the work you deliver.
The question sounds simple. What do you charge upfront before a project begins?
For a designer who has never lost money on a client who disappeared mid-project, it can feel like a straightforward administrative detail. But designers who have been left holding vendor invoices, open furniture orders, and weeks of unbilled labor know exactly what is at stake in the answer. Your deposit terms are not a formality tucked at the back of a contract. They are the financial architecture that determines whether you can pay your vendors on time, absorb a slow-paying client, and actually profit from the work you deliver.
Interior Design Community asked this question directly this week, and the response thread became one of the most practically useful conversations the QOTD series has produced. The specifics varied widely. The underlying logic was more consistent than it might first appear.
Educational content, not legal advice.
Why Your Deposit Terms Are a Risk Management Decision
Most deposit discussions start and stop at the client experience. Will this amount feel too aggressive? Will a large upfront number scare off a good lead?
These are reasonable questions, but they often push the more important analysis out of the conversation entirely. The right deposit structure is the one that reflects the actual financial exposure your business carries when it signs a contract. That exposure varies significantly depending on what you are committing to deliver and how much of your own money will be at risk before the client’s next payment arrives.
For a designer working hourly with no procurement component, the primary risk is lost time. For a full-service firm ordering custom furniture, coordinating trades, and managing logistics for a large renovation, the exposure is in a different category. The deposit terms need to match the liability.
Before settling on a percentage, work through three specific questions. How much of your time will you invest before the next payment is due? What vendor obligations will you carry between now and that payment? And what is the realistic outcome if this client exits after work has already started?
Payment timing is closely tied to this question, and it deserves its own analysis. For a closer look at how designers structure the back end of a project, see our breakdown of when designers actually take final payment.
If the answer to that last question would leave your business in a difficult position, your current deposit is not doing its job.
The Vendor Payment Problem That Deposit Discussions Usually Skip
One of the most underappreciated functions of an upfront deposit is its role in vendor payment logistics. This came up directly in the community thread and deserves more attention than it typically receives.
Designers who handle procurement are often collecting client funds and distributing them to vendors on that vendor’s payment schedule. Some vendors require payment in full before production begins. Others collect on delivery or at installation. In either case, the designer is the financial intermediary, and the timing of client payments determines whether the designer is funding the gap out of pocket.
“Make sure you collect enough to pay your vendors in full when they complete their job or project. Don’t ever make a vendor wait until you get ‘your balance owed’ from YOUR client.”
@houseoftudorupholstery
Vendor payment obligations are not negotiable the way client timelines sometimes are. A vendor who delivers on schedule expects payment on schedule, regardless of where things stand with the client’s outstanding balance.
The practical implication is this: procurement deposits and design fee deposits are solving different problems and should be structured accordingly. Collecting 50% of the design fee at signing does not protect a designer from a cash flow gap when a vendor invoice arrives before the client’s next payment is due. These are separate financial calculations, and conflating them is one of the more common mistakes designers make when setting up their initial terms.
For a deeper look at how procurement fees and markup structures fit into this cash flow picture, see our guide to interior design procurement fees: hourly rate versus markup.
Three Structures That Show Up in Working Design Businesses
There is no single correct structure. But the community responses represent a clear cross-section of approaches that are actually in use, each reflecting different service models and risk priorities.
The 50/50 Split Tied to a Hard Milestone
The most common structure in the thread: half at signing, half due before a specific deliverable.
“50% of design fees at signing. Remaining 50% due 48 hours before our First Look Presentation.”
@danafalerinteriors
The 48-hour trigger is the detail worth borrowing. Rather than collecting the balance after the presentation, payment is required before the meeting can be scheduled. The designer controls the timing, and the client understands from day one that the presentation is contingent on payment. Clients who know this expectation upfront rarely push back at the collection point.
This structure works well when the bulk of the design labor happens before the first major presentation and the project does not involve significant procurement liability early in the engagement.
The Phase-by-Phase Model
For designers working on flat fees across multiple phases, tying each payment to the phase it funds keeps cash flow aligned with the work being delivered.
“It all depends on the total cost. I work on a flat fee and am always paid for each ‘phase’ up front. Most of the time it’s 1/3 at signing, 1/3 at first presentation and 1/3 at second presentation.”
@jennifertaylordesign
The phrase “paid for each phase up front” is doing important work here. Payment comes before the phase begins, not after it concludes. This matters for cash flow, and it also resets the client’s active commitment at each stage of the engagement. The client is not just paying an old balance; they are choosing to continue.
For longer or more complex projects, this model adapts well to more than three phases, with each payment sized to cover the labor and obligations in the phase ahead.
Tiered by Project Scale
For firms managing a wide range of project values, different thresholds can call for different structures.
“Projects under 50k, I take 50% at signing and 50% before concepts. Anything over 50k, I break down getting 30% at signing, 60% at concepts and 10% before installation. Thinking of revising this”
@lanineill.interiors
The note “Thinking of revising this” is worth pausing on. Deposit structures that made sense when first designed may no longer match the current project mix, vendor relationships, or cash flow realities. The fact that a structure has functioned reasonably well to date is not the same as it being optimized for the business today. Revisiting is not a sign something broke. It is a sign the business grew.
Some firms pair a structure like this with a separate non-refundable retainer collected even earlier, at the very start of the client relationship. If you are weighing whether to add one, see our breakdown of three non-refundable retainer policy models that work.
Why Business Stage Changes the Right Answer
One of the most valuable contributions to this thread was an explicit argument against one-size-fits-all deposit advice. The right deposit structure for a newer design-focused practice is genuinely different from what a full-service procurement firm needs, and the community pushed back clearly on coaching that treats them as equivalent.
“It also depends on where you are in your business and what services you provide. Not all designers are alike…experience, service offerings, financial buffer, clientele, etc. A newer, design-focused designer should probably collect a minimum of 50% upfront because of their vulnerability. What happens when a new client ghosts them after they’ve done a site visit and a bunch of preliminary concept work? A deposit on the design work (at least) protects this vulnerable business. On the other hand, a full-service firm with years of doing procurement and project management for tons of clients is a different scenario altogether. Their deposit doesn’t have to cover just lost time, but money spent on procurement, etc. No one wants to get stuck with furniture that a homeowner doesn’t want to pay for.”
@interior_designher
The vulnerability framing is useful because it names what the deposit actually needs to protect against, rather than relying on a general rule.
For a newer designer, the primary exposure is time already spent: the hours invested in a site visit, preliminary concept work, and client onboarding before any payment milestone arrives. A 50% deposit at signing covers the most vulnerable window.
For a full-service firm managing procurement, the exposure extends to real dollars in open orders that cannot easily be returned or redirected. The deposit calculation there has to account for actual financial risk, not just professional time.
A practical test: if this client disappeared tomorrow, what would your business be left holding? If the answer creates genuine concern, your current deposit is not sized correctly.
If you are early in your business and still building these protections into your contracts, our guide on advice for new interior designers covers the contract and pricing fundamentals that make a deposit like this enforceable in the first place.
The Framework That Works Across All of Them
The community responses varied in specifics but converged on a set of underlying principles. @thecollectivefordesigners offered the clearest strategic framing in the thread:
“I’ve look at two things: 1. What it realistically takes for you to complete the first phase(s) of work. 2. What feels appropriate for your client base and positioning. If your process has two major phases, maybe you collect 50% upfront. If your projects span multiple years with 4+ phases and the first phase is primarily discovery, maybe it’s closer to 33%. A lot also depends on how you sell your services. If clients are buying based on trust, expertise, and access to you, you can typically justify a larger upfront investment. If they’re buying based on tangible deliverables tied to each phase, it may make more sense to collect only what’s needed to complete the upcoming phase. But regardless of structure, collect something upfront. Don’t work at a deficit or without enough consideration to give weight to your contract and commitment from the client.”
@thecollectivefordesigners
The final sentence is the through line for this entire discussion. Every designer in this thread uses a different structure. The one thing no one disagreed on was the underlying principle: collect something real, collect it before the work begins, and make sure it carries enough financial weight to hold the contract together on both sides.
The split between how you sell (trust and access versus tangible deliverables) is also worth thinking through carefully. A client who is buying your expertise and point of view is already making a relationship investment, and asking them to fund a larger portion upfront fits that dynamic. A client who is buying a specific set of deliverables may respond better to a structure that keeps each payment tied to the phase it funds.
Neither approach is wrong. The goal is a structure that reflects how your specific business works and what your specific engagements actually require.
The Practical Next Step
If your deposit terms have not been revisited since you wrote your first contract, this is a reasonable moment to look at them again. The question is not whether your current structure has worked. The question is whether it still fits the work you are doing and the real financial exposure your business is carrying.
Review the last three completed projects. If the client had exited at the midpoint, what vendor payments would have been pending? What labor would have been unbilled? What would you have absorbed?
If the answer to any of those questions creates discomfort, your deposit terms are the place to start. They are the first financial decision you make in a client relationship. Making them deliberately, based on the actual risks your business carries, is one of the more durable improvements a designer can make to their practice.
The conversations on To-The-Trade and across the Interior Design Community have covered payment structures, contract language, and financial management from multiple angles over the years. This thread is a strong reminder that deposit terms are not set-it-and-forget-it. They are a living part of a business that should grow with it.
