First: errors. Invoice issued twice. Correction. Refund. Complaint. Each case costs EUR 50–500 of handling plus customer relationship. In a typical SMB – 100–400 such cases yearly. Total EUR 12–125k.
Second: delays. Offer sent in 3 days instead of 3 hours – lost lead. Invoice issued a week late – longer DSO. Project delayed – upset customer, penalty, lost next contract. Total 5–15% of revenue annually.
Third: duplicate work. Two teams doing the same thing because they don't know about each other. A document created, found six months later, redone from scratch. A decision taken in a meeting, forgotten, taken again. Repeated work is typically 8–12% of operational capacity.
Fourth: lost leads. A customer leaves an enquiry, no answer in 24h, customer goes to a competitor. In a firm with 200 enquiries monthly and 25% conversion, every 10% of lost leads is 5 lost contracts. Annually: hundreds of thousands in lost revenue.
Fifth: team turnover. An employee leaves after a year of chaos frustration. Replacement cost: EUR 7–12k plus 3–6 months of reduced productivity for the rest. In a 30-person firm with 20% turnover – at least EUR 50k annually on this category alone.
