Yes, they do. Commercial buyers research system integrators the same way they research everything else: they search, they compare, and they check reviews before they ever pick up the phone. By the time a facilities director or IT leader calls your office, your Google reviews have already helped decide whether that call happened at all. Here's the proof, and the simple system your sales team can own this quarter.
How Do Commercial Buyers Actually Choose a System Integrator?
Most integrators assume the sales process starts when the prospect makes contact. The research says otherwise.
Gartner research on B2B buying found that purchasing teams spend just 17 percent of their total buying time meeting with potential suppliers. The other 83 percent goes to independent research, internal discussions, and comparing options on their own. And by the time they do reach out, the decision is largely made: 6sense found that 81 percent of buyers already have a preferred vendor at the moment of first contact, and the vendor that ultimately wins was on the buyer's day-one shortlist 95 percent of the time.
Read that again from a sales leader's perspective. The opportunities you're winning are largely opportunities where you made the shortlist before anyone called you. The opportunities you're losing to competitors you've never heard of? You probably never made the list, and you never knew the project was out there.
So what builds that invisible shortlist? Your reputation, your visibility in search, and increasingly, what buyers find when they Google your company name. Reviews sit right at the center of all three.
Do B2B Buyers Really Read Reviews Before Contacting a Vendor?
It's tempting to believe reviews are for restaurants and roofing companies, not commercial integration contracts. The data disagrees.
Research on B2B buying behavior consistently shows that 77 percent of B2B buyers read user reviews during their decision-making process. Studies aggregated by BusinessDasher found that more than 70 percent of B2B buyers read at least three to five reviews before contacting a vendor, and nearly 90 percent say a single negative review can remove a vendor from consideration entirely. And when buyers do turn to reviews, Google dominates: Google-based reviews account for roughly 79 percent of all online reviews across platforms.
Now put a face on those numbers. A facilities director at a regional hospital gets your proposal for a new access control system. Before she returns your salesperson's call, she does exactly what she'd do before hiring anyone: she Googles your company name. If she finds a complete profile with 40 recent reviews from commercial clients praising your project management and service response, your rep's next call gets easier. If she finds an unclaimed listing with three reviews from 2019, one of them a two-star complaint nobody responded to, that proposal just got heavier to carry.
Your competitors' profiles are one tab away from yours. That's the comparison happening before every first meeting, whether you participate in it or not.
Why Do Reviews Matter Even More Now That Buyers Use AI?
Buyers aren't just using Google anymore. According to 6sense research, 94 percent of B2B buyers now use AI tools like ChatGPT, Claude, Gemini etc., during their research process. A recent Responsive survey found that the top three ways buyers discover new vendors are web search at 33 percent, peer recommendations at 33 percent, and generative AI chatbots at 32 percent. AI recommendations have effectively pulled even with word of mouth.
When someone asks an AI assistant to recommend security integrators in your market, that answer doesn't come from nowhere. These tools draw heavily on public signals: your Google Business Profile, your review volume and recency, your ratings, and how consistently your company information appears across the web. An integrator with a complete profile and a steady stream of detailed reviews gives the AI something to cite. An integrator with a thin, neglected profile simply doesn't show up in the answer.
For twenty years, the referral was the backbone of integration sales. It still matters. But the referral now has a digital twin, and it's being generated by algorithms that read your reviews whether you've ever looked at them or not.
What Should System Integrators Do About Reviews This Quarter?
The good news: this is the highest-leverage, lowest-cost marketing move available to a system integrator, and it doesn't require a marketing department. It requires a simple four step process:
1. Claim and complete your Google Business Profile. Every location, every service line, real photos of your team and your work, accurate service areas. This takes an afternoon and most of your competitors haven't done it.
2. Build the review request into project closeout. Don't leave the ask to chance or to marketing. When the customer signs off on a completed project, the project manager or account rep requests a review while satisfaction is at its peak. Make it a line item on the closeout checklist, right next to the as-built drawings.
3. Respond to every review within a week. Positive or negative. A thoughtful response to a critical review often does more for a prospect's confidence than another five-star rating, because it shows how you handle problems. Buyers know no company is perfect. They want to see what happens when something goes wrong.
4. Aim for consistency over volume. Two or three new reviews a month, every month, beats a one-time blitz of twenty. Recency is a trust signal for both human buyers and AI engines, and a steady cadence tells them your quality is current, not historical.
Notice what this is: a sales process improvement, not a marketing campaign. It fits inside workflows your team already runs, and the people best positioned to earn the review are the ones who delivered the project.
When Does It Make Sense to Get Outside Help?
Reviews are the fastest win, but they don't work in isolation. When that facilities director reads your reviews and clicks through to your website, what she finds there needs to confirm what the reviews promised. Strong reviews pointing to a weak website, or to content that hasn't been touched in two years, creates a credibility gap that undercuts the trust you just earned.
If your team has the bandwidth to own the review process internally, start there this quarter. If the bigger picture, the website, the content, the profiles, the follow-through, keeps falling to whoever has a spare hour, that's usually the signal that it's time to bring in marketing support built for how integrators actually sell.
Either way, the first step costs nothing: Google your own company name and look at what your next prospect sees.
Frequently Asked Questions
Do commercial clients check Google reviews before hiring a system integrator? Yes. Research shows 77 percent of B2B buyers read reviews during their decision process, and most read at least three to five before making contact. Commercial buyers apply the same research habits to security and AV integrators that they apply to every other business decision.
How many Google reviews does a system integrator need? There's no magic number. Recency and consistency matter more than raw count. A steady flow of two to three reviews per month signals current, reliable quality more convincingly than a large but aging total.
Do Google reviews affect how AI tools recommend vendors? Yes. AI assistants draw on public signals including Google Business Profiles, review volume, ratings, and recency when recommending vendors. Integrators with complete profiles and active reviews are far more likely to appear in AI-generated recommendations.
Who should own review requests, sales or marketing? Sales should own the ask, built into project closeout when customer satisfaction is highest. Marketing (or your marketing partner) should own the profile itself and review responses. Splitting it this way keeps the request personal and the follow-through consistent.
