Most interior designers will tell you procurement is the worst part of the job, and most of them are underestimating how much it actually costs them, not in frustration or late nights, but in real money that leaves the studio every month without anyone noticing because it was never tracked in the first place.
According to a survey by the Interior Design Community (IDC), designers spend up to 250 hours of procurement work per residential project. That sounds like a lot until you start listing what it actually includes, at which point it starts to sound conservative.
Key takeaways
- Designers spend up to 250 hours per residential project on procurement tasks, most of it untracked and unpriced.
- The real cost is senior designers spending £30,000+ a year of design talent on work that generates no creative value.
- Average interior design studio net profit is 3 percent. Top performers hit 14 to 15 percent. The gap is often operational overhead, not design quality.
- Spreadsheet-based FF&E schedules carry an 88 percent error rate, and a single specification mistake can add four to six weeks to a project.
- Hiring helps with capacity but does not fix the structural problem. The fix is eliminating the operational steps, not delegating them.
Where 250 hours of procurement time actually goes
Procurement is not one task, it is dozens of small tasks repeated across every item on every project, and the cumulative time is what makes it so expensive.
Sourcing a single piece of furniture means contacting three to five suppliers, comparing specifications that are presented in completely different formats, requesting pricing that may or may not include VAT, delivery, or the finish your client approved, waiting for replies that arrive days or weeks apart, and then doing the same thing again for the next item on your FF&E schedule. A mid-size residential project might have 80 to 150 line items. Multiply the sourcing time per item by the number of items and you begin to understand why procurement is not a phase of a project but an ongoing parallel workstream that runs across 40 to 60 percent of the total project duration.
Then there is everything that happens after sourcing: building the FF&E schedule, updating it every time a specification changes or a client changes their mind, chasing quotes that were promised last week, coordinating delivery dates across multiple suppliers in multiple countries, managing customs documentation for cross-border orders, tracking shipments, handling damage claims, and manually copying product data between spreadsheets, emails, PDFs, and presentation documents that were never designed to talk to each other.
This is the work that designers describe as "chasing," and it is remarkably difficult to quantify because it happens in the gaps between everything else, a few emails here, a phone call there, twenty minutes spent updating a spreadsheet that should have taken five.

How procurement erodes studio profit margins
The average interior design studio nets around 3 percent profit, while top-performing firms hit 14 to 15 percent. The difference between those numbers is rarely design quality, it is operational efficiency, and procurement administration is where most of the leakage happens.
According to industry benchmarks from Scarlet Thread Consulting, interior designers bill approximately half of their working hours when they have assistance. Studio principals who also run the business bill only 10 to 15 hours per week. The rest is non-billable operational work, and procurement administration is where a disproportionate share of it lives.
A case study from Logistis, an accounting firm specialising in interior design businesses, found that a senior designer was spending 60 percent of her time on administrative tasks. When the studio hired an assistant to handle that work, the senior designer took on five additional projects, paying for the new hire within two months.
The maths is straightforward. A senior designer in London earning £50,000 a year who spends 60 percent of their time on procurement administration is effectively spending £30,000 a year of design talent on work that generates no creative value, work that a procurement coordinator earning £28,000 to £30,000 could handle instead. But most boutique studios of three to fifteen people do not have a separate procurement team, so the designer absorbs the work themselves, and the cost disappears into the general overhead of running the studio.

What spreadsheet errors cost interior design studios
Up to 88 percent of spreadsheets contain errors, and in FF&E procurement those errors translate directly into wrong orders, delayed projects, and margin loss.
Most FF&E schedules still live in spreadsheets, and research on manual data handling confirms what most designers already suspect. In procurement, these errors show up as incorrect dimensions copied from a supplier's website, a formula that broke when someone added a row, a finish code that was updated in the email thread but not in the schedule, or a lead time that was accurate three weeks ago but is no longer.
The cost of these errors is real but invisible. A specification mistake that results in the wrong item being ordered does not just cost the price difference, it costs the time to identify the error, coordinate the return, find an alternative, get client approval on the substitution, and reorder, a process that can add four to six weeks to a project timeline. Multiply this across even a small number of items and you understand why designers routinely underestimate project hours by 20 to 30 percent, with the untracked time almost always in procurement follow-up and corrections.
Version control compounds the problem. When multiple people in a studio are working on the same project, and the FF&E schedule exists as a file that gets emailed, duplicated, and edited independently, nobody can say with certainty which version is current. This is not a technology problem, it is an infrastructure problem, and it has been the default way studios operate for decades.
Why designers keep sourcing from the same suppliers
Procurement overhead has a secondary cost that rarely gets named: designers end up sourcing from the same small group of suppliers on every project because they do not have the time to find new ones.
Discovering a new supplier, establishing a trade account, negotiating terms, understanding their product range, learning their lead times and ordering processes, all of this takes hours of work before a single product is specified. When you are already spending half your week on procurement administration for current projects, the idea of investing more time to expand your supplier network is not realistic, no matter how much you know it would improve your design work.
The result is that studios get stuck in a cycle where the same suppliers appear on every project, the work starts to look the same, the margins stay the same, and the creative possibilities narrow because the sourcing possibilities are narrow. Designers know this is happening, they can feel it, but the operational load of procurement makes it nearly impossible to do anything about it.

How to reduce procurement overhead without hiring
Hiring a procurement coordinator helps with capacity, but it does not fix the structural problem. The scattered information, the manual data entry, the email chasing, none of that disappears when you add a person to do it, it just moves to a different desk.
The instinct in most studios is to hire someone to handle procurement, a junior designer, a procurement coordinator, an assistant. And hiring can help, the Logistis case study proves that. But the work itself, the scattered information, the manual data entry, the email chasing, the spreadsheet maintenance, the coordination across disconnected systems, does not go away when you add a person to do it, it just moves to a different desk.
The actual fix is removing the work. Not delegating it, not organising it more efficiently, but eliminating the operational steps that should not require a human in the first place. Automated sourcing that matches project requirements to supplier catalogues, FF&E schedules that update themselves when specifications change, order management that replaces email threads with a single system, logistics coordination that surfaces lead times and delivery status without manual follow-up.

Frequently asked questions
How much time do interior designers spend on procurement?
According to a survey by the Interior Design Community (IDC), designers spend up to 250 hours of procurement work per residential project. This includes sourcing products, chasing quotes, building and updating FF&E schedules, coordinating deliveries across multiple suppliers, and managing customs documentation for cross-border orders. Most of this time is untracked because it happens in the gaps between other work.
What is the average profit margin for interior design firms?
According to Scarlet Thread Consulting, the average net profit for interior design firms sits around 3 percent, while top-performing firms achieve 14 to 15 percent. The difference is often in how much operational time leaks out of the studio on procurement tasks that were never priced into the project fee.
How many errors do spreadsheet-based FF&E schedules contain?
Research suggests that up to 88 percent of spreadsheets contain errors. In FF&E procurement, these show up as incorrect dimensions, broken formulas, outdated finish codes, and lead times that are no longer accurate. A single specification mistake can add four to six weeks to a project timeline once returns, substitutions, and reorders are factored in.
Why do interior designers use the same suppliers on every project?
Discovering a new supplier requires hours of upfront work: establishing a trade account, negotiating terms, learning their product range, lead times, and ordering processes. When designers are already spending half their week on procurement for current projects, investing more time to expand their supplier network is not realistic, so the same suppliers appear on every project and the creative possibilities narrow.
Is hiring a procurement coordinator the best solution?
Hiring solves a capacity problem but not a structural one. The scattered information, manual data entry, email chasing, and spreadsheet maintenance does not disappear when you add a person, it just moves to a different desk. The more effective fix is eliminating the operational steps that should not require a human in the first place through automated sourcing, self-updating FF&E schedules, and centralised order management.
