When Do You Take Final Payment? Designers Talk Timing, Trust, And Getting Paid Without The Stress

It sounds like a throwaway question: “When do you take final payment?”

But for interior designers, the answer is rarely simple. The timing of that last check can expose issues in the contract, the client relationship, and the designer’s own business model.

Sometimes it’s collected too late. Sometimes it’s tied to an arbitrary milestone. Sometimes it never arrives at all.

So we asked the Interior Design Community: when do you ask for final payment, and what have you learned about getting paid in full—on your terms?

Hundreds of designers responded. The answers reveal more than just payment policies. They show how business maturity, firm boundaries, and clear contracts shape every successful project.

The Pain of Waiting Too Long

One community member admitted:

“We’ve been doing it per our contract when work is completed—but it’s sometimes tricky.”

That “tricky” part? It’s the gray zone between a finished design and a finished project. Maybe a final pillow is still in transit. Maybe the photo shoot is scheduled for next month. Maybe the client says they’ll send the check right after install.

But that soft landing rarely feels solid.

“I used to wait until the end of the project to get a payment—but I have learned my lesson on that one.”
— @kwsdesign

Now she collects 50% upfront and 50% upon submission of the first design draft. That shift alone protected her from chasing down payments at the most emotionally exhausting part of the job.

Install Is Not a Billable Event

For many designers, the end of a project is when they’re most vulnerable. The creative is done, the vendors are paid, the product is sitting in the space—and the check still hasn’t cleared.

“Final payment is always 3–5 days before installation!!!”
— @david_michael_interiors

No exceptions. If the client hasn’t paid in full, the team doesn’t roll up with trucks and accessories. That policy may feel strict, but it’s smart. And increasingly, it’s the norm.

No More “End of Project” Mental Math

Designers who work on a fixed-fee or hourly basis often deal with payment delays because clients don’t feel like the project is over.

Sometimes it’s an unreturned lamp. Other times it’s the promise of a future shoot.

“Really struggling with this right now… one client won’t pay me until after the photo shoot. And another hasn’t been responsive for weeks.”
— @grandchampinteriors

That’s not a contract problem. That’s a communication problem. But it started as a contract problem.

The Case for Clear Milestones

Some of the most seasoned designers in the IDC community break their payments into phases—detaching payment from arbitrary end dates and connecting it to actual deliverables.

“I do a deposit to start, and then the balance due at concept acceptance. For goods, it’s 100% upfront, always.”
— @linda_merrill

“We break our projects down into 3 retainers for construction finishes and 3 payments for furnishings: deposit, materials, and install labor. Final install labor payment is at the time of install.”
— @eclecticdesign.co

They also include clauses for overages and contingencies—anticipating scope creep before it becomes an issue.

“Final payment isn’t tied to the end of the project. It happens long before.”
— @kingsway_cointeriors

Hourly Designers Need Boundaries Too

“Anything that is hourly is billed biweekly so I’m never left with a big bill owing at the end of a project.”
— @marsha_sefcik

And for fixed-fee design, she takes 50% upfront and the remaining 50% before the detailed design is delivered. This removes any pressure to perform for the final check. The work has already been paid for.

What About Retainers and Refunds?

“If there’s money left after the project, I refund the client.”
— @omforme_interior_design

It’s an elegant approach when tracked well. But it requires strong trust and transparency, which not every designer or client is prepared for.

How the Community Handles It

@kevin_twitty_interiors: Full payment upfront
@linda_merrill: Deposit to start, balance due at concept approval
@marsha_sefcik: Hourly invoiced biweekly, design fee split 50/50
@eclecticdesign.co: Retainers tied to phases, with product paid at each stage
@david_michael_interiors: Final payment due before install
@grandchampinteriors: Struggled with payment linked to post-project photos
@kwsdesign: Phased model that protects against nonpayment during final deliverables

Contracts Are Living Documents

One of the most repeated sentiments in the comment thread? Your contract should evolve.

Clients aren’t trying to be difficult. But when expectations are vague—or not explicitly spelled out in your terms—they’ll fill in the blanks themselves. That’s how photo shoots become payment milestones. That’s how installs become leverage points.

If something doesn’t feel right in your current process, don’t wait until the next red flag to adjust.

When you’re billing thousands (or hundreds of thousands) on a project, “we’ll settle up later” is not a business strategy.
