We spent 2023 paying off $62,000 of consumer debt, and I remember what the last payment felt like. So when someone asks me whether they should put a $5,000 vending machine on a credit line, my first reaction is not excitement about the business. It is a small knot in my stomach. I have been on the wrong side of interest, and I do not want anyone walking back onto it for a fridge.
And yet I do not think the answer is “never borrow.” Some debt buys you a thing that pays its own bill. Most does not. The whole question is which kind you are looking at, and there is a way to tell before you sign anything.

The machine I’m using as the example
To keep this concrete I’m going to use a real price. VendBuddy (full disclosure: VendBuddy is my company) sells the SandStar AI smart cooler direct, and its listed range is $4,995 for the single-door cooler up to $6,995 for the two-door and three-zone freezer versions. There is also a $65 monthly software fee on every unit, which covers the cellular connection and the camera software. It’s a glass fridge that unlocks when you tap a card, watches what you take, and charges you when the door closes.
I didn’t run these. My route was traditional snack and soda machines, and I sold it after about a year. But the debt question doesn’t care which machine it is. A $5,000 purchase on borrowed money follows the same rules whether it’s a cooler, a used truck for a side business, or a pressure washer.
Consumer debt versus a loan that has a job
The $62,000 we paid off was consumer debt. It bought things that did not produce anything. Every dollar of interest on it was a dollar leaving our family with nothing coming back.
A machine loan is different in one specific way: the thing you bought is supposed to make the payment. That’s the only reason it can ever be okay. So the test is not “is debt bad?” It’s “will this asset reliably earn more each month than the payment, starting soon enough that I’m not covering the gap out of my paycheck for long?”
If the honest answer is “probably, maybe, if the location works out,” then it’s still consumer debt. It’s just consumer debt with a business story attached.
The three numbers I’d want before borrowing a dollar
1. What the building will realistically net
Not gross. Net, after the product, the property’s commission, card fees and that monthly software charge. VendBuddy’s published ranges put these coolers at roughly $1,800 to $5,000 a month in sales at a decent site, with 22 to 32 percent of that left over. A weak site under about 150 people a day might sell $1,200 or less. That spread is the whole ballgame, and it comes from the building, not the machine. I wrote about this years ago in why locations make all the difference, and nothing about AI hardware has changed it.
2. The actual monthly payment
People look at the interest rate. I look at the payment, because the payment is what has to be covered every single month.
3. How long until it’s paid off
Because the day the machine is paid off is the day it starts actually paying you.
Running it both ways
Here’s a hypothetical. Say the all-in cost of the entry cooler, including a first load of product, lands around $5,500, and you’ve found an office where you honestly expect about $2,400 a month in sales once it settles in. At the low and high end of that 22 to 32 percent margin, that’s roughly $530 to $770 a month of net.
| How you pay for it | Monthly payment | What’s left each month at $530 net | Interest cost |
|---|---|---|---|
| 0% intro credit, cleared in 15 months | about $333 | about $197 | $0 if you clear it in time |
| Equipment loan, 10% down, 15% APR, 3 years | about $156 (plus $500 down) | about $374 | roughly $1,100 over the term |
| Cash | $0 | all $530 | $0, but the cash is gone from savings |
On paper the 0% option wins by a mile. Zero interest. But notice what it demands: $333 a month, every month, whether the machine has ramped up yet or not. New placements are slow for the first couple of months. If month one sells $1,200 instead of $2,400, the machine nets maybe $300 and you’re writing a check from your own account.
The equipment loan costs about $1,100 more over three years. What you get for that $1,100 is a payment small enough that even a slow month probably covers it. For a lot of people that’s worth paying. I would not call it the wrong choice just because the spreadsheet says interest is bad.
The danger with 0% is the cliff at the end. Intro periods on business credit usually run somewhere between 9 and 18 months, and after that the rate on whatever’s left often jumps into the 20s. If you only pay minimums, you wake up in month 16 with a balance and a 26% rate. That’s the exact kind of debt we spent a year crawling out of.
My rule, if I were doing this
- No signed location, no loan. Borrowing for a machine that doesn’t have a home yet is just buying an expensive appliance with interest on top.
- If the net covers the payment with room to spare, a 0% line is fine, but only with an automatic payment set on day one that clears the whole balance before the intro window closes. Balance divided by months left. Never the minimum.
- If the net only barely covers the 0% payment, use a longer fixed loan instead, or don’t do it.
- Keep a repair and slow-month cushion in cash that you did not borrow. A few hundred dollars at least.
- Know the worst case. If the location throws you out in month six, can you still make the payments from your job while you find a new spot? If not, the loan is too big.
If you do go the 0% route and your credit file is thin, 7 Figures Credit handles the application side across several lenders at once, which beats doing four hard pulls yourself. They can’t make a bad location good, though, and nobody can.
The part of this that’s actually about freedom
I want to zoom out for a second, because this is where it connects to why I write this blog at all.
When we were paying off our debt, the goal wasn’t a number on a spreadsheet. It was getting to the point where our money worked for us instead of the other way around. A machine that pays for itself in eight months and then drops a few hundred dollars a month into your account is a small piece of that. A machine you’re still paying for in month 20, at a location that never really worked, is the opposite. It’s another boss.
The difference between those two outcomes almost never comes down to the financing. It comes down to whether you did the boring work first: finding a building with real traffic, getting a signed agreement, counting people. If you want a shortcut on that part, VendBuddy (vendbuddy.io/app) pulls offices, apartment buildings, gyms and hotels in any ZIP code along with the person who actually makes the decision, and you can buy a single credit pack rather than signing up for a monthly plan.
I’d also say this plainly: if you have high-interest debt right now, pay that down before you borrow for any business. I laid out that whole calculation in pay off debt or invest. A guaranteed 22% saved beats a hopeful vending machine every time.
What stacking can look like, if it works
One cooler isn’t a life change. Here’s how it can grow, as a purely hypothetical example with numbers from the ranges above. Say a paid-off cooler nets $600 a month. You use that $600 to cover the payment on a second machine at a second signed building. When that one’s paid off, the two together cover a third. None of this needs more money from your job after the first one, as long as each new building is as good as the last. The risk is that you get excited and add machines faster than you add good locations. Every operator I’ve talked to who got burned did exactly that.
Slow is fine. Paid off is better than big.
If you want the operator-level version of this — the numbers, the checklists, the step-by-step — the VendBuddy team wrote it up here: SandStar Smart Cooler Price and Financing: Five Models, Real Payback (2026).
Before you do anything
Write down three numbers on paper: what you believe the building will net each month, what the payment will be, and how many months until it’s paid off. If you can’t fill in the first one with a straight face, you’re not ready to borrow, and that’s okay. Go find the building first. The machine will still be for sale next month.
