The wrong item arrives on install day. It’s the right product, wrong finish. The right finish, wrong size. The right size, wrong quantity. You’ve been here, or you know someone who has.
A single transposed digit, an incorrect fabric code, a bar-height stool ordered instead of a counter: the procurement phase of an interior design project is where a small error becomes a large problem. The Interior Design Community asked designers directly how they verify specs before placing orders. The responses showed that, universally, the answer is everyone who has been in business long enough to learn the hard way.
The Layers of Review: How Experienced Firms Structure It
The designers who manage significant project volume have built multi-layer review systems into their specs process. Not because they don’t trust their team, but because they understand that a single-point review is always vulnerable to single-point failure. A common structure: the person who enters the data reviews their own work first, then passes it to a second reviewer with full review authority, not just a spot-check. Two passes, two people.
“Order gets checked by me, then by our specialist, then back to me to check again, then out to client for them to review. Ideally it gets checked four times before production.”

Including the client in the final verification adds a fifth set of eyes and creates a documented approval chain. That paper trail matters when a vendor error shows up on install day, and you need to demonstrate what was actually approved.
“I check the RFQ, designers check the vendor’s invoice, project manager checks the client proposal, procurement checks the vendor acknowledgment.”
@kathleendwalsh
Each document type gets a designated reviewer. Not the same person doing the same thing repeatedly, but the right person reviewing the right spec document at the right stage. The structure prevents review fatigue and keeps accountability clear.
What Gets Checked at Each Stage
The checkpoints matter, but so does what’s being verified at each one. A comprehensive spec review covers dimensions (height, width, depth, and delivery access), exact finish and fabric codes (alphanumeric codes, not just color names), quantity in the appropriate unit for the item type, COM specifications if client’s own material is being used, lead time current at the time of order, ship-to address including any receiving warehouse logistics, and production options like knock-down construction for tight delivery access. One wrong character in a material code can mean an entirely different product arrives on install day.
“I check the PO, I check the order, I check the acknowledgment, I check the confirmation, I check the ship notice! And even then sometimes the wrong thing shows up because all the vendors have to check too.”
@mariematthewsinteriors
The vendor acknowledgment, confirming what they understood the order to be, is the catch that happens before production. That’s the best possible time to surface a discrepancy, and it’s a step that some designers skip until they’ve learned why they shouldn’t.
The Physical Reality: Measuring Before Ordering
Spec review isn’t only about the paperwork. It’s about the physical environment that the items have to enter. Some designers conduct site visits specifically to verify measurements before making a purchase, rather than relying on drawings alone. In high-density buildings with restricted elevator access, that means confirming exact dimensions and knock-down construction options before the order is placed, not after delivery.
“It’s astonishing how many details come to me in my sleep that weren’t even on my mind that I need to get up during the night and double check or I won’t be able to go back to sleep! As the owner, it will come out of my pocketbook if it’s wrong.”

If it comes out of your pocketbook, it pays to lose a little sleep.

The Cultural Side: Creating a Team That Reports Errors
Review systems are only as effective as the culture surrounding them. When team members are afraid to surface errors, those errors get discovered later, at the worst possible time. The firms that catch mistakes during the order phase rather than on install day have usually made a deliberate decision about how errors are treated internally.
“A company policy of ‘mistakes sometimes happen, it’s to be expected when we are processing millions of dollars worth of orders each year, so bring the mistake to my attention as soon as you catch it so we can fix it ASAP’ is best because it prevents employees from attempting to hide a mistake out of fear and often allows us to fix the mishap before the client install.”
@cookdesignhouse
A culture that treats mistakes as problems to solve quickly, not events to punish, is what makes the review structure work in practice. The system and the culture have to go together.
“That second set of eyes can be the difference between bar stools or counter-height stools arriving on install day.”
@mc_virtualassistants
It doesn’t take a large firm to build this. It takes a second person, a clear handoff, and a policy that makes it safe to say “I caught something.”
For Solo Designers: Building Review Into Your Own Process
Not everyone has a team. For solo designers, the review system has to be designed around a single person, which means building a deliberate structure to compensate for the absence of a second reviewer.
A few approaches that work for solos: time-separate reviews (enter the order, then review it the next morning before submitting, since the interval gives fresh eyes on your own work), print and check (reviewing a physical printout catches errors that a screen review misses), client sign-off (send the client a formatted summary of every item including specs before placing orders), and templated spec sheets (a consistent format for every order document reduces the chance of missing a field). You’re not alone in losing sleep over this. The designers who sleep better are the ones who built the system first.
