Direct Answer
Continuing to serve an unprofitable large customer makes sense only if the customer provides undeniable strategic value—such as establishing marquee brand credibility, absorbing fixed overheads during early scale, or offering guaranteed volume that drives supplier discounts across other accounts.
If none of those strategic conditions exist, an account with high revenue and negligible gross margin is a liability that absorbs management time, ties up working capital, and crowds out profitable customers.
Businesses must measure 'cost to serve': freight, custom engineering, payment collection delays, dedicated account management, and payment risk.
Why This Matters for Sponsors and Leaders
A 20% revenue customer who pays in 120 days at 5% gross margin can quietly consume 60% of an SME's working capital, starving higher-margin accounts.
What to Examine
Calculate customer-level net contribution margin after deducting all dedicated operational overheads.
Assess how much bank borrowing is required to fund this specific customer's payment cycle.
Determine what profitable opportunities are missed because capacity is blocked by this account.
Propose adjusted pricing or payment milestones; if they refuse, plan a phased, respectful exit.
Practical Leadership Insight
Not all revenue is equal. Some revenue feeds your business, and some revenue eats your business from the inside. Never be afraid to let an unprofitable customer go to your competitor.
