Most businesses that struggle to grow aren't struggling because of low revenue. They're struggling because of poor margin management. You can double your sales and still be worse off if your costs are growing faster than your income. Here's how to fix that.
Revenue is vanity. Profit is sanity.
Before optimising anything else, know your numbers cold: gross margin, contribution margin, and net margin. Most SME owners only track revenue and bank balance — by the time a margin problem is visible, it's already serious.
Understanding Your True Cost Structure
The first step is mapping every cost to the right category. Most businesses misclassify costs, which leads to bad pricing decisions. Break your costs into three buckets: Cost of Goods Sold (COGS) — direct costs tied to producing or acquiring the product; Variable Operating Costs — costs that scale with sales volume (shipping, packaging, payment fees, commissions); and Fixed Overhead — costs that exist regardless of sales (rent, salaries, software subscriptions).
Once you have this mapped, calculate your true unit economics: revenue per unit minus COGS minus variable costs equals your contribution margin per unit. This is the number that determines whether your business model is viable.
5 Margin Optimisation Levers
Renegotiate supplier pricing
Most suppliers offer volume discounts that businesses never ask for. If you've been buying consistently for 6+ months, request a pricing review. A 5% reduction in COGS on a 40% margin product improves that margin to 45% — a 12.5% relative improvement.
Audit your payment and fulfilment fees
Payment processing fees (1.5–3.5%), marketplace commissions (8–15%), and fulfilment costs are often treated as fixed — but they're negotiable or reducible. Consolidate payment providers, review FBA fee categories, and compare 3PL rates annually.
Reprice strategically, not reactively
Pricing decisions based on competitor monitoring alone are reactive. Build a pricing model based on your target margin, then assess whether the market supports it. If not, the problem is cost structure — not price.
Identify and eliminate low-margin SKUs
The Pareto principle applies to product margins: 20% of SKUs often generate 80% of profit. Run a margin report by product line. Discontinue or reprice SKUs below 30% gross margin unless they serve a strategic purpose (loss leaders, bundle anchors).
Optimise your product mix
Shift marketing spend toward your highest-margin products. If your ads are driving traffic to your lowest-margin SKUs because they have the best CTR, you're optimising the wrong metric. Blended margin across all sales is the target metric.
Building a Monthly Margin Dashboard
Set up a simple monthly dashboard with four metrics: gross margin %, contribution margin per unit, blended net margin %, and month-over-month trend. Review it on the first Monday of every month before any other business discussion. What gets measured gets managed.
