I'm the office administrator for a 35-person electrical contracting company. I manage all equipment purchasing—roughly $400,000 annually across 20 vendors. That includes generators, most frequently Briggs & Stratton units for jobsite power and emergency backup.
If you're deciding between buying from a distributor or working with an installer, here's what I've learned from about a dozen generator purchases since 2021. I'll compare them on four things: total cost, compliance, convenience, and support.
1. Upfront Price vs. Total Cost
A distributor will almost always quote a lower price for the same Briggs & Stratton generator. That's because they're just moving boxes. The installer is selling a system that works.
My first bulk purchase was five Briggs portable generators for a new project site. The distributor's quote came in 15% below the local installer's. I felt clever for a week. Then our electrician gave us a separate invoice for connecting transfer switches, pulling permits, and hauling away the old units. The total landed only 2% below the installer quote—and that didn't count the four hours I spent coordinating delivery and inspection dates.
Why does this matter? Because the quoted price is rarely the final price. At least, that's been my experience with distributors in our region.
2. Compliance: Who Owns It?
This is where the “cheap” distributor option really hurts. When you buy a mobile generator for temporary use, compliance isn't just about plugging things in. You're dealing with EPA emissions requirements, local noise ordinances, and fuel storage rules. For standby units in commercial buildings, NFPA 110 outlines strict installation and testing standards.
A distributor hands you the machine and says “good luck.” An installer typically handles permits, inspections, and code compliance as part of the job.
Here's what I didn't fully understand until an inspection failure: the distributor didn't know local code. We had to pay twice for an electrical inspection—once for the failed attempt, again after the installer fixed it. That $300 mistake turned a $1,600 savings into a net loss. The trigger event that changed my thinking happened in 2023 when a mobile generator got rejected because the grounding wasn't up to the updated NEC requirements.
3. Convenience: One Call vs. Many Calls
For a single generator, the installer wins on convenience, no question. One call, one set of paperwork, one bill.
But here's the surprising part: for bulk orders, a distributor can actually be faster. We once needed six mobile generators for a three-week outage project. The distributor had stock and could ship the next day. The installer had to source units individually, and their schedule stretched the timeline to two weeks.
So the “right” choice depends on whether you're buying one or many. Need one? Installer. Need a fleet? Distributor, probably.
4. Support After the Sale
Briggs & Stratton generators come with a factory warranty, but you need an authorized service center for warranty work. Some distributors are also service centers—we've bought from one that handles claims well. But many are not, which means shipping the unit back to a central location if something fails.
Installers usually have a relationship with a local service network. That can matter when a generator dies during a power outage. I've had a unit down for two weeks waiting on a warranty part because the distributor had no after-hours service. The installer we now use stocks common parts and answers the phone on weekends.
Oh, and one more thing: check whether your installer is authorized to do warranty repairs. Some are strictly installers, not certified technicians. You'd think they'd know the product—until they don't.
What Should You Choose?
If you're a facility manager with in-house electricians and you're buying multiple generators for a known project, a distributor may be your best bet. You can handle compliance internally. But if you're a smaller business buying one Briggs & Stratton generator and you don't want to become a code expert, pay the installer premium.
I can only speak to commercial projects in the Midwest. If you're in an area with stricter environmental rules, your calculus could be different. But the principle holds: the lowest quote is only the beginning.
The bottom line? Add up every cost—compliance, inspections, downtime, warranty handling—before choosing. On our last two purchases, the installer quote was actually the better total value. It took me five years and twelve orders to understand that. Take it from someone who learned the hard way.
