Electrical Supply Houses: How to Open a Trade Account and Get Contractor Pricing at Graybar, Rexel, and Anixter

7 min read·Updated April 2026

Material costs are 30–50% of most electrical jobs. The difference between buying wire at Home Depot retail and buying it through a Graybar trade account can be the difference between a 20% margin job and a 35% margin job. Every electrical contractor needs a supply house relationship — here's how to build one from day one.

The Quick Answer

Opening a trade account at Graybar, Rexel, or Anixter (now Wesco) requires your electrical contractor's license, EIN, LLC or business formation documents, and 2–3 trade references. The application takes 15 minutes and approval typically comes in 3–5 business days. Once approved, you'll get contractor pricing (20–40% below retail on wire, panels, and devices), net-30 payment terms, and access to will-call counters that open as early as 6:00 a.m. for job-day pickups.

Why Supply Houses Beat Home Depot for Electrical Materials

The electrical supply house is the professional's alternative to big-box retail. A 250-foot spool of 12/2 Romex at Home Depot runs $110–$130. The same spool at a Graybar trade account might run $75–$90 on your contractor pricing tier. Multiply that across a whole house rewire — 2,000–4,000 feet of wire — and you're looking at $200–$600 in material savings on a single job. Supply houses also stock commercial-grade products that Home Depot doesn't carry: 600A service equipment, bus duct, motor control centers, specialty conduit fittings, and commercial panel boards. They also know electrical products deeply — the counter staff at a Graybar branch can help you spec an unfamiliar panel or find a substitute part when the spec'd item is backordered.

How to Open a Graybar Trade Account

Graybar Electric is the largest U.S. electrical wholesale distributor with 290+ branches nationwide. Visit your local branch (find it at graybar.com/locations) with: your state electrical contractor license, your EIN or Tax ID number, and your LLC or corporation documents. Request a credit application from the inside sales counter. Provide 3 trade references — other suppliers who have extended you credit — or personal financial references if you're brand new. Graybar also accepts online credit applications through their website. Once approved, you'll receive a customer account number and can start purchasing on net-30 terms. New accounts are typically started on a $2,000–$5,000 credit limit that increases as you build payment history. Graybar's online ordering platform lets you place will-call orders the night before for morning pickup.

Rexel and Anixter: Alternative Accounts Worth Having

Rexel USA operates 400+ branches and is strong in commercial and industrial electrical supply. Their contractor pricing tiers reward volume — the more you buy, the better your pricing. Rexel also has a strong online ordering system with real-time branch inventory. Open your Rexel account at rexelusa.com/pro or walk into your nearest branch. Anixter (now merged into Wesco International) specializes in wire, cable, and network/data cabling — particularly valuable if you're doing commercial work that includes low-voltage or data wiring alongside electrical. Wesco's pricing on bulk wire purchases is competitive. Having accounts at two supply houses gives you price comparison leverage and ensures you can get materials even if one branch is out of stock on a critical item.

Will-Call vs Delivery: Managing Job-Day Materials

Most supply houses offer two fulfillment options: will-call (you pick up at the branch) and delivery (they bring it to the job site). Will-call is the default for most residential contractors — you pick up materials the morning of the job, keep material costs aligned to specific jobs, and avoid delivery minimums. Supply house delivery typically has a minimum order of $200–$500 and a lead time of same-day to next-day. For larger commercial projects, negotiate job-site deliveries for material drops tied to your construction schedule. Delivery works best when you know your material list 24–48 hours in advance. Will-call works best for service work where you determine materials after diagnosing the problem.

Managing Material Costs on Bids

The most common mistake new electrical contractors make is using retail pricing to estimate material costs on bids, then buying at trade pricing and not adjusting their markup accordingly. Standard material markup for electrical contractors is 15–25% above your trade cost — not above retail. If you pay $500 for materials at trade pricing, you invoice $575–$625 in materials. This markup covers your time picking up materials, carrying costs, waste, and the cost of miscellaneous supplies not itemized in the bid. Track your material costs by job using accounting software like QuickBooks or Jobber's job costing feature. Comparing your actual material cost to your estimated material cost on every job is how you refine your bidding accuracy over time.

FREQUENTLY ASKED QUESTIONS

Can I open a supply house account before my business is officially formed?

Most supply houses require a state-issued contractor license and EIN to open a trade account. Form your LLC first, get your EIN from the IRS (free and instant online), and then apply. The whole process can be completed in a week if you have your contractor license in hand.

What happens if I miss a net-30 payment at a supply house?

One late payment typically results in a warning and possible temporary hold on new purchases. Consistent late payment leads to credit limit reduction and eventual cash-on-delivery requirements. Pay your supply house invoices on time — your trade credit reputation matters more than your personal credit score in the contracting world.

How much should I mark up electrical materials?

Standard markup is 15–25% above your trade cost, not above retail. On larger commercial bids, material markup compresses to 10–15% because general contractors scrutinize material pricing. On residential service work, you can maintain 20–25% markup because customers aren't comparing your material costs to a competing bid.
