Your material purchases represent 30 to 50% of your revenue. Saving 20% on them doubles your net margin. Lever 1 — Batch your orders: instead of ordering as you go, group your orders fortnightly. Volume = negotiating power. Lever 2 — Create competition: always keep 2 to 3 suppliers per category. Show competing quotes (without the names). Lever 3 — Negotiate at end of month/quarter: sales reps have cyclical targets. At the end of the period, they are more flexible on discounts. Lever 4 — Ask for trade terms: many tradespeople buy at retail prices out of habit. Open a trade account and negotiate a permanent discount (usually 10 to 15% as a baseline). Lever 5 — Cash payment: offer payment within 7 days in exchange for an extra 3 to 5% discount. On €50,000 of annual purchases, that is €2,500 saved. Our clients who apply these 5 levers save an average of €18,000 a year on purchases.
