The sales KPIs that matter most to a commercial electrical distributor are organic (same-day) sales growth, gross margin rate, backlog and project mix, digital share of sales, sales mix by end market, SG&A as a share of sales, and the working-capital pair of receivables and inventory. These are the measures the largest distributors put in their own results, so this page uses their reported numbers rather than invented averages. Wesco reported record 2025 net sales of $23.5 billion, organic growth of 8.6% and a 21.1% gross margin, down 50 basis points, with backlog up 19%. Graybar reported net sales of $12,875.6 million, up 10.6%, and a gross margin rate of 19.3% versus 20.1%, which it put down primarily to competitive pricing pressures.

Rexel reported that digital channels carried 34% of group sales in 2025, and Sonepar said digital sales were 45% of its European revenue and 33% of its U.S. revenue. Industry-wide benchmarks for sales per employee, inventory turns and collection days do exist, but in the paid NAED PAR Report, so this page does not repeat figures it could not read. The last public PAR highlights read here are for 2012. Every source was read on November 3, 2026. This page is not financial advice.

Organic and same-day sales growth

Headline sales in electrical distribution move with acquisitions, currency, copper prices and the number of selling days, so the big distributors report an adjusted growth figure alongside the reported one. Wesco calls it organic sales growth, which removes acquisitions and divestitures, foreign exchange and workdays. Rexel reports same-day sales growth, which adjusts for calendar effects. A sales team should be judged on that adjusted number, not on the headline.

Wesco said the 2025 organic increase reflected volume growth in its CSS and EES segments plus a favorable impact from price. Its EES segment grew 6.7% reported and 7.5% organic for the year. Splitting growth into volume and price is the next step for any rep or branch scorecard, because a year of cable price increases can flatter a territory that did not win new business.

Gross margin rate, and what moves it

Gross margin rate is the sales KPI that most directly shows pricing discipline. In 2025 both of the largest U.S.-listed or SEC-reporting electrical distributors saw it fall, for reasons a sales leader can recognize.

Wesco attributed its decline to competitive pressures in the public power market in its utility segment, and to large project sales in its EES and CSS segments. That is the trade-off every electrical sales team manages: big data center and infrastructure projects add volume and backlog, but at lower margins than day-to-day contractor and maintenance business. Graybar's 10-K adds that some products, such as wire and cable, conduit, enclosures and fittings, are tied to copper and other commodities, and that its gross margin rate on them is relatively constant over time though not necessarily in the short term.

The NAED figure is from a 2014 release about 2012 data and is shown only as history. The current PAR Report is sold by NAED and was not read for this page, so no current industry median is given.

Backlog, project sales and data center share

For distributors that sell into large construction and data center projects, backlog is a forward sales KPI. Wesco reported record total company backlog at the end of 2025, and its results put data center sales on their own line.

Tracking project business separately matters because it behaves differently from book-and-ship sales. Wesco tied its lower margin and higher inventory to growth in large projects, so a scorecard that blends the two will misread both.

Digital share of sales

Digital penetration has become a reported KPI in electrical distribution, and the two largest European-based groups now publish it.

Rexel lists the benefits it sees as customer stickiness and share of wallet, a service gap with smaller competitors, and team efficiency and productivity. Wesco said its digital transformation should bring greater cross-sell, improved pricing and higher working capital turns. Neither claim is a benchmark, but both show why digital share sits on a sales dashboard rather than only an IT one.

Sales mix by end market and customer

Electrical distributors sell to contractors, industrial plants, utilities and institutions, each with different margins and buying cycles, so mix is a KPI in its own right. Graybar reports its sales by vertical market every year.

The same filing describes a fragmented market: thousands of local and regional distributors alongside several large national and global ones, with Graybar estimating that the top five account for approximately 40% of the U.S. market. For a sales leader that means share-of-wallet and new-account counts are as important as growth from existing customers.

SG&A to sales and sales productivity

Selling, general and administrative expense as a share of sales is the cost side of the sales KPI set, because most of it is people. It is also where the big distributors are now pointing productivity tools.

No source read on November 3, 2026 publishes a current industry benchmark for sales per employee or gross profit per salesperson in electrical distribution. NAED says its PAR Report covers employee productivity and invoice lines, but the report is paid and was not read here.

Receivables, inventory and cash

A distributor finances inventory and contractor credit before it is paid, so collection and stock levels are sales KPIs too. Wesco's 2025 results show how fast growth can absorb cash.

Graybar said the average number of days of sales in trade receivables and its days in inventory both increased modestly in the fourth quarter of 2025. Wesco said it expected to collect cash from its higher receivables balance in the first quarter of 2026. Neither company publishes a target DSO, and no current industry DSO benchmark was found in the sources read, so none is given. The 2012 NAED PAR Highlights put typical inventory turnover at 4.3, a historical figure only.

A scorecard to start with

Read together, the filings point to a short monthly scorecard for an electrical distribution sales team.

For peer comparison, NAED's PAR Report benchmarks financial ratios, employee productivity, inventory turns and invoice lines across groups such as best in class (top 25% by return on assets), sales volume, customer segment and number of branches. NAED lists the 2026 edition at $879 for members and $2,699 for non-members.

Questions people ask

What are the most important sales KPIs for an electrical distributor?

Organic or same-day sales growth, gross margin rate, backlog and project mix, digital share of sales, sales mix by end market, SG&A as a share of sales, and receivables and inventory days. These are the measures Wesco, Graybar and Rexel report in their 2025 results.

What gross margin do large electrical distributors earn?

Wesco reported 21.1% for 2025 and Graybar reported 19.3%. Both were lower than in 2024, Wesco because of large project sales and public power pricing, Graybar primarily because of competitive pricing pressures.

How much of electrical distribution sales is digital?

Rexel reported 34% of group sales through digital channels in 2025 and aims for 50% in the midterm. Sonepar reported digital sales of 45% of European revenue and 33% of U.S. revenue.

Is there an industry benchmark for sales per employee or inventory turns?

NAED's PAR Report covers employee productivity and inventory turns, but it is a paid report and was not read for this page. The last public PAR highlights read here, for 2012, put typical inventory turnover at 4.3 and gross margin at 21.6%.

Why does backlog matter for an electrical distributor's sales team?

Project business, such as data centers and utility work, is booked well before it ships. Wesco reported backlog up 19% at the end of 2025 and data center sales of $4.3 billion, up about 50%.
