Mais chaque mauvais prospect coûte du temps, tue ta marge et te rapproche du burnout. Voici comment sélectionner. ## How this article unfolds 1. the automatic yes trap — A $3,000 deal accepted without filtering eats 40 hours of work, turning your margin negative at $75/hour. 2. three questions to filter clients — You check in one or two calls whether the client has a clear problem, a fixed budget, and sole decision power. 3. the refusal that pays off — Every no to a bad client frees up time for a good client paying $200/hour with half the friction. 4. audit your last 5 clients — You count how many met the 3 criteria: fewer than 3 out of 5 means you're accepting too many bad clients. --- ## The hidden cost of the bad client You say yes to a prospect because they have a budget and a request. But you don't count: the 5 clarification calls, the unpaid revisions, the delayed signature timeline, the client who negotiates the price at the last minute, the one who disappears after the diagnosis. Result? A 3,000€ deal that costs you 40 hours of real work. At 75€/hour, your margin is negative. Worse: you've blocked that time from a **good** client who would have paid the same price with half the friction. Consultants at 0-5k€/month accept everything because they believe every sale counts. That's wrong. A bad sale costs more than it brings in. ## 3 criteria to say no without guilt **Criterion 1: Does the client have a clear problem or just a vague desire?** A good client comes with an identified pain (« We're losing 30% of leads in conversion »). A bad client comes with a vague idea (« We'd like to do better »). Bad clients go from diagnosis to « I'll think about it » because they never had a real problem to solve. Simple test: ask a diagnostic question in 2 minutes. If they can't answer precisely, it's a bad client. Say no. **Criterion 2: Is the budget fixed or will you negotiate it later?** A good client tells you « We have 5,000€ for this ». A bad client asks « How much does it cost? » and makes you justify the price over 3 calls. Clients who negotiate the rate before seeing the value are bottomless pits. They'll also negotiate after signing, ask for unpaid add-ons, and leave if you say no. Simple test: if you have to justify your price before presenting the solution, it's a bad client. Say no. **Criterion 3: Can the client decide alone or do you need to convince 5 other people?** A good client has the power to say yes. A bad client says « I'll talk to my partner / my boss / my accountant » after every call. These clients slow everything down, create doubt, and often disappear because someone else said no. Simple test: ask on call 1 « Who else needs to approve this decision? » If the answer is more than 2 people, it's a bad client. Say no. ## Why saying no is your best sale Every time you say no to a bad client, you say yes to: - **More time for good clients**: you can do better work, more results, more testimonials. - **Real margins**: 3,000€ in 15 hours of work (200€/hour) vs 3,000€ in 40 hours (75€/hour). - **Less stress**: no client who backs out, disappears, or asks you for things out of scope. - **A reputation as a professional**: good clients respect those with standards. Bad clients respect those who say no. Saying no isn't losing a sale. It's protecting your margin and your health. ## Next step Look at your last 5 clients. How many met these 3 criteria? If fewer than 3, you're accepting too many bad clients. It's time to change. ## FAQ **What if I say no and miss out on a sale?** You're not missing out on anything. A bad client who costs 40 hours and kills your margin isn't a sale—it's a loss. A good client gives you 200€/hour instead of 75€/hour. Better 1 good client than 3 bad ones. **How do I know if it's a bad client before signing?** The 3 criteria tell you in max 2 calls. Clear problem? Fixed budget? Sole decision-maker? If you're hesitant on any of the three, it's a bad client. Trust your instinct. **I'm at 0€/month, can I really say no?** Yes. Saying no to 3 bad clients at 3k€ each (= 9k€ of false revenue and 120 hours wasted) frees you up for 1 good client at 5k€ with 20 hours of real work. It's more profitable and healthier. Start with the criteria, not with desperation. ## About BIZZY CONSULTING, founded by Heman Toussaint, is the client-acquisition ecosystem for independent consultants and coaches: the BIZZIES platform, 1:1 coaching and a complete method.
