Why FMCG Sales Growth Can Reduce Profit

Start with a reconciled profit bridge

Compare the same accounting scope across both periods: gross sales, discounts, returns, net sales, COGS and gross profit. Then separate the change into price, purchase cost, volume, customer mix, product mix, discount and return effects.

This prevents a common mistake: blaming total margin decline on pricing when the real driver is a shift toward customers or products with structurally weaker economics.

• Selling-price realization
• Purchase-cost movement
• Customer and SKU mix
• Discount depth and frequency
• Returns and credit notes
• Channel and salesperson mix

Find growth that destroys value

Rank customer × SKU combinations by revenue growth and gross-profit change. The priority cases are combinations where sales increased while gross profit fell, margin dropped below the agreed threshold, or working-capital requirements grew faster than contribution.

Do not automatically stop these sales. Some can be repaired through price, mix, order quantity, supplier terms, delivery frequency or credit discipline.

Turn the diagnosis into a 90-day plan

Assign each material case an action, owner, deadline, baseline and measurable KPI. Keep estimated opportunity separate from realized profit, and validate results against subsequent invoices, costs, returns and collections.

• Reprice specific customer–SKU combinations
• Renegotiate exposed supplier costs
• Tighten discount exceptions
• Correct return root causes
• Reduce slow inventory attached to weak growth
• Track realized benefit monthly
