Let’s cut to the chase—if you’re a “by application” supplier like me, you’ve probably stared at that long, blank field in procurement portals that says “portfolio link” or “work samples” and thought, Do I actually need this? I get it. For a second, I used to think “by application” meant we’re just here to solve a specific, weird problem someone’s got, not flash a bunch of past jobs like a high schooler showing off their senior project. Spoiler: I was so wrong, and it almost cost me a huge contract last year. Let me walk you through why digital portfolios aren’t just a fancy trend—they’re the difference between being the guy who gets ignored and the guy who gets the call when someone’s like, “Hey, we actually need your exact skill set.” By Application
First, let’s get on the same page about what a “by application” supplier even is, for anyone who might be new here. We’re not the people selling pre-made desk chairs or off-the-shelf software you can download and buy in 2 clicks. We’re the ones who do the custom, tailored stuff—think a specialized manufacturing jig for a medical device that’s way too niche for Amazon, or a niche SaaS integration that connects two tools no one else has bothered to sync. When a company reaches out to us, they don’t just want a product. They want proof that we can solve their specific, messy, unique problem, right? Because if it was simple, they’d go with a standard provider. But here’s the thing: procurement teams are busy. Like, so swamped that they can’t sift through 10-page whitepapers or parse a 2-hour video call just to figure out if we can deliver. That’s where the digital portfolio stops being a “nice to have” and starts being a non-negotiable.
Last year, I had a prospect from a big pharmaceutical company reach out. They needed a custom precision component for a COVID test kit, something that required laser-level tolerances and material science that’s super specific to their production line. I thought, Perfect—we’re the only ones who do this. I skipped the portfolio because I’d been so busy with another project, and I just sent over a 2-sentence note saying “we do this, hit me up.” Guess what? They ghosted me. A week later, I saw they awarded the project to another supplier. I emailed the procurement lead to ask what went wrong, and her reply was blunt: “You didn’t include any samples of similar work. We had 8 other suppliers send links to their portfolios, and their work was way more relevant to what we need. We couldn’t risk a supplier with no track record of this exact niche.” Ouch. That stung, but it also woke me up. I went back, built a simple portfolio, and within 6 months, I closed a $1.2M contract with a biotech firm that explicitly said they found me because of a case study in my portfolio that was almost identical to their problem.
Now, let’s talk about why this isn’t just my personal bias—because I’ve talked to 12 other by application suppliers (manufacturers, tech devs, engineering consultants) over the last year, and almost all of them say the same thing. For by application, trust is everything. When you sell a custom solution, the buyer is taking a leap of faith that you understand their needs, have done this before, and won’t flake halfway through. A portfolio isn’t just a collection of pretty pictures—it’s proof of that trust. Let’s break down what makes a good by application portfolio different from, say, a graphic designer’s portfolio. A designer’s is all about aesthetics, but ours is about results.
Your portfolio doesn’t need to be a 50-page website with a fancy logo (though that doesn’t hurt). It needs 3 key things. First, relevant case studies. Don’t just dump every single project you’ve ever done. If you’re a supplier for industrial automation, don’t feature the time you made a custom birdhouse for a local zoo. Feature the 2-3 projects in the last 2 years that are closest to what the prospect needs. For example, if your next lead is a food packaging company needing a custom seal tester, your case study should be about the drink company you did one for last quarter—not the automotive part you made in 2021. Each case study should have 3 simple parts: the problem (what the customer was struggling with, why off-the-shelf didn’t work), what you did (specifics, not vague “we made a solution”), and the result (hard numbers if you can get them—time saved, cost reduced, error rate cut). Those numbers matter way more than “it looked good.”
Second, work samples. Wait, not just photos—proof. If you’re a fabrication supplier, a photo of the part is fine, but add a link to a test report or a short clip of it working in the customer’s line. If you’re a dev building custom tools, a link to a demo video or a GitHub repo snippet of the integration is way better than a description. For my laser component work, I added a 15-second video of the part being inspected with a micrometer, showing the tolerance levels down to 0.001mm—stuff I couldn’t easily explain in an email. That’s the kind of concrete stuff that stops a prospect from saying, “Yeah, that’s cool, but can you actually do that?”
Third, social proof. A quick quote from a past client, no more than 2 sentences. Not just “great supplier”—specific. Like, “They delivered the custom seal tester 2 weeks ahead of schedule and cut our packaging error rate by 18%” from the Head of Operations at that drink company. Procurement teams trust other operations heads way more than they trust my sales pitch. And if you don’t have great quotes yet, ask for a short LinkedIn recommendation—those take 2 minutes, and anyone can see they’re real.
Wait, but let’s address the counterargument I know half of you are having: “I don’t want to give away my best work to competitors.” Totally fair. I felt that too. When I first started my portfolio, I was worried some big rival would see my exact part specs and copy them. But here’s the thing: if a competitor is already doing that work, they probably already have those big contracts. And if you’re bidding on a unique project, your specs are tailored to that specific customer’s needs—so even if someone copies the concept, it won’t fit another job. Also, most prospects get super confused if you say “I can do that” but won’t show them any proof. It makes you look unprofessional, like you’re hiding something. I’ve had prospects ask for NDA access to my full work samples, and that’s totally fine—just don’t put everything public, only the stuff that’s general enough that competitors can’t steal it, but specific enough to prove your skill.
Another big question: “Do I need a full website, or can I just use a simple tool like LinkedIn or a Google Site?” Let’s be real, no one expects a $10k website for a niche by application supplier. When I started, I used Google Sites—it took me 3 hours to build, cost nothing, and had all the case studies, samples, and quotes I mentioned. LinkedIn is also okay, but a dedicated (super simple) page makes you look more intentional. Wait, but here’s a hack: a lot of procurement portals now let you add a “vendor profile” or “work reference link” directly, so you don’t even need to send it as an attachment. Just put that simple portfolio link in your profile, and when someone searches for your niche, your portfolio pops up. I’ve had prospects reach out on LinkedIn saying they found my Google Site when searching for “custom laser medical components”—that’s free lead gen, right there.
Let me also talk about what happens if you skip this, because that’s the story that stuck with me. Last year, I had another prospect who reached out about a different component. This time, I was prepared—I had my portfolio ready. I sent it over, and within 2 days, they scheduled a call. During that call, the engineering lead spent 10 minutes scrolling through my case studies and saying, “Oh, we had the exact same problem with our last supplier. This case study is perfect.” That call turned into a $450k contract. Compare that to the lost contract earlier, where I sent nothing and got ghosted. The difference? The portfolio. It didn’t just prove I could do the work—it started the conversation before we even talked.
Wait, but is there any scenario where you don’t need it? Let’s be honest. If you’re a 1-person shop that only does work for one regular client, maybe not. But even then, if that regular client refers you to someone else, the first thing that new prospect is going to ask for is proof of what you do. And if you’re just starting out, don’t have a ton of past work? That’s okay. Case studies can be from your own internal projects, or even prototype work. For example, if you’re a new dev building custom tools, you can do a free project for a local non-profit, document the process, and add that as a case study. It’s not a big client, but it proves you can deliver a custom solution.
The bottom line here is: for by application suppliers, your value is tied to your specific skills and track record. Off-the-shelf providers don’t need portfolios because their value is in their pre-made product. But you? You sell solutions that are built for one problem, so you need to show that you’ve done that before. A digital portfolio isn’t a vanity project—it’s your sales team working 24/7 to prove you’re the right guy for the job.
If you’re a by application supplier sitting here thinking, “I should make one but I’m too busy,” trust me, it takes way less time than you think. My first portfolio was 3 case studies, 2 videos, and 1 quote—all thrown together in a night when I was procrastinating on another project. It’s not about being perfect; it’s about being visible and credible. And if you’re a procurement person reading this (wait, hey, maybe this is for both sides), if you’re a by application supplier, stop making excuses. If you’re a procurement person, ask for that link—it’ll save you so much time.
Ultrasonic Extractor If you’re a fellow by application supplier who’s been on the fence about building a digital portfolio, hit me up anytime to chat about what worked for me. No sales pitch, just a couple of guys who’ve been burned by ghosting and closed big deals because of a few case studies. Let’s make sure we stop getting passed over for guys who take 10 minutes to put a simple portfolio together. It’s worth it.
