When you say 'I guarantee $15,000 in X days or you don't pay,' how does the deal structure actually work? Do you generate and book the leads yourself for free upfront, do they get charged per booked appointment with a card on file, do they pay upfront, and if you don't hit the target do they get a full refund?
Yes, that's exactly how it works. Something like: 'if I don't get you 20 booked appointments in 60 days, you don't pay' or 'if I don't hit you $20,000 in the next 60 days, you don't pay.' I use that as leverage to get on the call in the first place. The 'or you don't pay' part is a money-back guarantee — we charge X for the service, and if we don't hit the result, we refund 100% of it. It helps to make yourself credible in that moment ('I'm a real person, you can Google me, here's my ID' — my old business partner actually used to do that literally). The exact wording is flexible — 'money-back guarantee,' 'or you're out $0,' 'you will have spent $0' — it's just different phrasings of the same idea: if this doesn't work for you, you are literally no worse off than before.
I use a guarantee very commonly in cold email and other marketing methods — I'll guarantee X result in Y time or you don't pay. It's not exactly true if you take it super literally, since at some point in time they will have paid, but the framing is short and fits nicely above the fold of the copy. When somebody actually gets on the call, I clarify it's a money-back guarantee: if by the time I said I'd achieve the results I haven't, they end up in the same state they started in — the state where they didn't pay. I haven't had many problems with this, but I'm also experienced at explaining the mechanics — I've heard of situations where less experienced people run a similar offer, get on a call, the prospect asks how it works, and they fumble the explanation ('well, you pay me and then later I give you your money back'), which doesn't match what the email implied. So it comes down to skill in framing it live: I'm happy to front-load the opportunity, get people on a call, showcase a ton of value, and let them arrive at trusting me based on my YouTube, Google presence, etc. — results may vary based on how well you can do that yourself. If you don't want to run the exact same offer, you can just change the language at the end from 'or you don't pay' to 'or I'll give you all your money back' — and nowadays I wouldn't even recommend a plain refund, I'd add something extra on top, like 'or I'll give you your money back and get you a night at your favorite steakhouse.' When you do that and actually mean it, it massively increases your top-of-funnel — maybe 300% more people through the door — and the cost is just a 5-10% refund rate plus a small bonus, which is nothing compared to the volume gained.
You don't have to guarantee dollar-sign outcomes — I've worked with these kinds of businesses for about a decade so I have a reasonable sense of what value I can drive, but if you're new to this it's completely understandable that you're not comfortable promising a dollar figure. Offer something else instead. A few variants: tell them you won't charge a cent unless they absolutely love it and ask you to keep going. Or say you'll deliver X, Y and Z, or you'll keep working for free until you do (weaker, but I've used it myself — we did this at Pacific Creative Group with my old business partner). You could also put real risk on the table, like offering to buy them an Amazon gift card or refund them if you don't deliver. Instead of ROI, you could frame it around hours saved per week (hard to track in practice, but usable). Or just offer a 100% satisfaction guarantee — tell them your sole goal is their satisfaction, and if they don't see the value, you won't charge them. A guarantee does two things: it makes people much more likely to want to work with you, and it makes you much more likely to actually follow through on what you promised.
You should absolutely guarantee meetings because guarantees align your incentives with the client’s and remove most of the downside. If you screw up you only lose time, but you gain experience and the client still sees value. For example, guarantee 20 sales appointments in 60 days. If you hit the target, the client is happy and you get paid, building a strong relationship for future work. If you deliver between 0 and 20 appointments, the client still gets some results, you may not get paid, but you leave a positive impression because you provided value for free. The worst case—zero appointments—is statistically unlikely; with a uniform distribution across 0‑20 there’s only a small chance of getting nothing. In practice, if you’re competent and consistent, the odds of hitting the guarantee are well over 50 %. That means, on average, you’ll earn roughly half of your fee per client (e.g., a $2,500 fee yields about $1,250 on average). Even when you fall short, you gain learning and goodwill. The key is to set a realistic guarantee, back it with a solid case study, and understand that the guarantee pushes you to deliver and helps you learn faster.
I always do. A guarantee isn't just promising I'll do X; it's not promising I'll make you $50,000. In offer terms, a guarantee is: I guarantee you I'll make you $50,000, or I'll give you all your money back and then give you a $250 gift card to the restaurant of your choice. That's what I consider a guarantee. Many people worry when they start a new industry and someone like me says you should guarantee stuff, thinking they can't guarantee because they're not good at it. The reality is, if you don't have a guarantee in your offer, you're leaving about three times the top of the funnel on the table, according to my math, maybe more, at the cost of maybe 5% of your margin, because your refund rate will be much lower than you think. Assuming a 5% refund rate, mathematically you get 3x top line for a 5% reduction in bottom line. Doing the math, that's 285% of the money you'd otherwise make without a guarantee. Meaning it's illogical not to include a guarantee. I also think guarantees make you work harder from a motivational perspective. If you compare two universes—one where you offer a guarantee to a customer and one where you don't—you'll work harder in the universe with the guarantee, because you're personally incentivized to perform. So there's really no reason not to do a guarantee; it's better for you and better for the client, who gets better results. It is immoral not to guarantee your services—that's my takeaway.
