Distribution is a margin business. You buy for less than you sell, and the difference has to cover every truck, every warehouse square foot, every rep's salary, and every operational system you run — and still leave something for the owner. Understanding where your margins should be, why they are where they are, and what levers actually move them is the difference between running a profitable distribution business and running a high-revenue business that never quite makes money.
Gross Margin vs. Net Margin: The Distinction That Matters
Gross margin is revenue minus cost of goods sold (COGS), divided by revenue. It measures how much you retain after paying for the product itself — before warehouse, labor, delivery, and overhead. Net margin is what's left after all of those costs.
Distributors frequently cite gross margin as their profitability metric and then are surprised when they're cash-poor. A 20% gross margin sounds healthy until you realize your delivery costs are 8%, warehouse is 4%, sales is 3%, and admin is 3% — leaving 2% net margin on a business doing $3 million in revenue, which is $60,000 in net income. Profitable on paper. Tight in practice.
Both metrics matter, but net margin is what actually determines whether the business is worth running.
Industry Benchmarks by Vertical
Wholesale distributor margins vary significantly by what you're distributing:
- Food and Beverage: Gross margin 12-20%, net margin 1-4%. Highly competitive, low barriers to entry, commodity pricing pressure on most SKUs.
- Specialty/Premium Food: Gross margin 20-35%, net margin 4-8%. Branded, differentiated products with more pricing power.
- Jan-San / Facility Supplies: Gross margin 18-28%, net margin 4-8%. Recurring consumable purchasing, decent pricing power on branded items.
- Industrial Supplies: Gross margin 25-40%, net margin 5-12%. More technical products, less commoditization.
- Foodservice Equipment: Gross margin 25-45%, net margin 6-15%. Higher ASP, more complex sales, significant installation and service components.
- Health and Beauty / Personal Care: Gross margin 20-35%, net margin 5-10%.
- Specialty Chemicals: Gross margin 30-50%, net margin 8-15%.
If your margins are significantly below these benchmarks for your vertical, the problem is typically in one of four places: pricing, freight, account mix, or COGS.
The Freight Cost Problem
For distributors running their own delivery operations, freight is the margin killer that most owners underestimate. A route with 12 stops, 400 miles driven, and a driver earning $28/hour plus a truck at $0.65/mile fully loaded costs roughly $600-800 per day to operate. If that route generates $8,000 in daily revenue at a 20% gross margin ($1,600), freight is consuming 37-50% of gross profit.
The way to improve route economics without raising prices: increase stop density (more deliveries per mile), increase average order size per stop (minimum order requirements and effective upselling), and eliminate unprofitable stops (accounts with small orders on inconvenient routes that never grow).
For distributors using third-party carriers, the issue is freight pass-through. If you're absorbing freight costs rather than passing them through to accounts, you're subsidizing delivery for every account. Charging freight on orders below a minimum order threshold — and waiving it above — creates the right incentive structure: accounts that want free delivery need to order enough to justify the route stop.
Pricing Strategy
Most small distributors use cost-plus pricing: calculate your landed cost for a SKU, add a target margin percentage, and that's your price. This is simple and ensures you're not selling below cost, but it leaves margin on the table where the market would bear a higher price, and it doesn't account for competitive pressure where cost-plus produces a price above market.
A better approach is a hybrid: use cost-plus as the floor, then validate against market pricing for each category. For commoditized SKUs where buyers price-shop, your margin is constrained by the market. For differentiated or specialty items, the market may support a premium. Knowing which of your SKUs are in which category lets you optimize margin across the portfolio rather than applying a uniform markup to everything.
Volume Discount Structures That Don't Destroy Margin
Volume discounts are a standard expectation in wholesale. The trap is structuring them without modeling the margin impact. A 5% volume discount at a 15% gross margin is not a 5% reduction in margin — it's a 33% reduction in margin dollars. At $100,000 in monthly revenue with 15% gross margin, you have $15,000 in gross profit. A 5% discount reduces revenue to $95,000 and gross profit (assuming the same COGS) to $10,000 — a 33% decline in profit dollars.
Discount structures that work better: tiered discounts based on annual volume commitment (not per-order size), category-specific discounts (discounting high-margin categories to reward purchasing, not low-margin commodities where you have no room), and discount earned through payment behavior (a 1% discount for payment within 10 days — which also improves your DSO).
Reducing Cost of Goods
Your COGS is negotiated, not fixed. Strategies that work:
- Consolidated purchasing: If you're buying from 8 vendors when 4 would cover the same categories, you're splitting volume that could be consolidated into higher purchase tiers with each supplier.
- Annual purchase commitments: Committing to a minimum annual purchase volume in exchange for a lower wholesale price — only makes sense for your highest-velocity SKUs.
- Early pay discounts from suppliers: Most manufacturers offer 1-2% for payment within 10 days. On $1 million in annual COGS, capturing those discounts consistently is $10,000-20,000 per year.
- Reducing slow-moving SKUs: Every SKU you carry that moves fewer than 2-3 units per month is costing you carrying costs without contributing meaningfully to revenue. SKU rationalization — cutting the tail of slow-movers — improves inventory turnover and frees up cash for faster-moving product.
