Active B2B accounts across the US, Canada, and Mexico.
Active SKUs across 6 categories — all in stock, all listed at wholesale.

Full-time employees across ops, procurement, support, and tech.
2014 — The garage.
PartNexus began in a 4,000 sq ft garage in Edison, New Jersey, with two people, a single shelf, and a frustration.
Our founder, Eli Marsh, spent ten years running parts counters for independent repair shops before starting the company. The pattern was the same at every shop: parts ordered in the morning arrived two days later, switches failed two months after install, and every invoice arrived with an MOQ that made no sense for a four-bay shop trying to keep its shelves lean.
He started PartNexus with a single thesis — that the wholesale parts business had not been meaningfully rebuilt in thirty years, and that a distributor who treated small and mid-sized shops as their primary customer, not a downstream afterthought, would earn trust faster than the bigger players could.
"We did not want to be the cheapest. We wanted to be the one the shop owner calls when they need a part at 4pm and the customer is picking up at 5."
— Eli Marsh, founder
That posture — speed, transparency, and no minimums — has not changed. The garage became a 12,000 sq ft warehouse in 2016, a 40,000 sq ft warehouse in 2019, and the current 80,000 sq ft Edison facility in 2024. We now stock 5,247 SKUs and ship to 2,400+ active B2B accounts from a single rooftop.
We are still privately held, still New Jersey-headquartered, and still answer the phone during business hours.
A decade, six inflection points.
What started as a single shelf grew into a 80,000 sq ft operation. The moves we made — and the ones we did not.

No minimum order, ever
A shop needs one switch to test fitment — they should not have to buy fifty. The catalog price is the same whether you order one unit or one pallet.
Same price, same speed
No 'gold tier' express shipping, no 'platinum' account support line. The wholesale terms you see at sign-up are the same terms you get on order 240.
Honest about the parts
If a part is a re-manufactured unit, we say so. If a SKU has known fitment caveats, the SKU page lists them. We do not make a switch look newer than it is.
Answer the phone
Wholesale sales line picks up 8am-6pm EST, Monday through Friday. After hours, email goes to the on-call rep. The phone does not go to a queue.
Stay wholesale
We are not a hybrid retail / wholesale shop. We do not sell to consumers. The catalog, the pricing, the UI, the support line — every part of the operation is tuned to the B2B account.
