Buying a Vending Business: Due Diligence Checklist & Red Flags (2026)

Red flag: Seller can only provide self-generated spreadsheets, no third-party card processor statements or bank deposit slips that match daily collection logs.

Ask: Can I see the last two years of monthly collection reports and match them to your business bank statements and card processing statements?

Red flag: Food/snack spoilage above 3–5% of sales or consistent over-stocking indicates poor route management; extremely low COGS may signal the seller is buying product without paying full wholesale.

Ask: What is your actual product loss rate per location, and can I see invoices from your wholesale supplier to verify your gross margin calculation?

Red flag: Commissions above 20% of gross sales at key locations are eating most of the profit, or some locations demand flat rent that exceeds the location’s net earnings.

Ask: For each location, what commission or rent do you pay—is it a percentage of sales, a flat site fee, or something else—and have any commissions been renegotiated recently?

Red flag: Add-backs include a full owner salary but the owner runs all routes themselves; normalized SDE plummets once you hire a driver to replace that labor.

Ask: Walk me through every line item you add back to calculate SDE—specifically, are you paying yourself a market-rate route driver salary or just taking draws, and what would it cost to hire a full-time driver to cover your current workload?

Red flag: Average machine age exceeds 10 years without a documented replacement cycle; repair costs are eating 5%+ of revenue; no maintenance records or reliance on one part-time technician.

Ask: What is the exact make, model, and year of each machine in the route, and can you show me the last 12 months of service calls and repair invoices?

Red flag: No separation between the person filling machines and counting money; cash losses of 3%+ of cash collections are considered normal; no daily tally sheets.

Ask: Describe your current cash-handling procedure—who collects, who counts, who verifies, and what is your historical shrinkage percentage?

Red flag: Long drive times between stops (30+ minutes) that could be condensed with route optimization; machines serviced on a rigid schedule regardless of actual inventory need, leading to wasted labor.

Ask: Can I see the daily route sheet for a typical week, including miles driven and time spent at each location, and do you currently use any telemetry to track stock levels remotely?

Red flag: Reliance on a single wholesale club that could change pricing or discontinue key items; no backup supplier or ability to buy directly from manufacturers.

Ask: Where do you buy your product, how often, and is there a discount structure based on volume? Are there any supply agreements in place, or do you just walk into a cash-and-carry?

Red flag: Most locations have no written agreement and the key contact at the facility has changed recently; any loss of even one location would drop net income by more than 15%.

Ask: For each of your top 5 revenue locations, show me the written location agreement (if any) and tell me how long the machine has been there and how frequently the decision-maker turns over.

Red flag: One location generates over 30% of total gross profit, and that location’s lease or office occupancy is in flux.

Ask: What percentage of your total gross profit comes from your single largest location, and what would happen if that location’s building manager asked you to remove the machines next month?

Red flag: A new micro-market operator is targeting your best locations, or the school district is replacing vending with cafeteria meal apps.

Ask: Have any of your locations been approached by a micro-market or “healthy vending” competitor in the last year, and what did you do to retain the account?

Red flag: Two or more locations are in office buildings with anchor tenants recently downsizing or going remote/hybrid, cutting foot traffic by 40%.

Ask: What is the typical daily footfall at each location now versus pre-COVID, and are any locations known to be reconsidering their office footprint?

Red flag: Written agreements explicitly prohibit assignment upon change of ownership, or verbal agreements are with a manager who has no authority to bind the property owner.

Ask: Can all existing location agreements be legally assigned to my new entity at closing without consent from the property owner, or will we need to get new signatures?

Red flag: Several machines are actually owned by a leasing company with a UCC-1 financing statement still open; buying the business without paying off the lease could result in repossession.

Ask: Provide a list of every machine showing whether it is owned free and clear, leased, or under a financed purchase contract—and supply payoff letters from any secured creditors.

Red flag: Food-handling permits have lapsed or the business never obtained a required state vending machine or sales tax permit, creating liability for the buyer.

Ask: What specific licenses and permits do you operate under—sales tax ID, health department food service permit, local privilege license—and can I see current copies for every jurisdiction?

Red flag: The seller has not been collecting sales tax on taxable items like candy and soft drinks properly, or is treating all sales as exempt under the wrong code.

Ask: How do you report and remit sales tax for different product categories, and have you ever been audited by the state? Show me your last three filings.

Red flag: Seller wants to walk away after a 2-day handoff, leaving you to cold-call location managers without any warm introduction.

Ask: What specific, structured training period are you offering—including ride-alongs and in-person introductions to every key location contact—and how many weeks will you be available for questions afterward?

Red flag: The only driver is the seller’s spouse, who will leave immediately, and there is no backup plan or documented route manual.

Ask: Who besides you physically services the route today, and will they remain with the business under my ownership for at least six months to ensure continuity?

Red flag: Seller intends to clear out all inventory at close, leaving you with empty machines and no merchandising, or will charge you extra for on-hand product at inflated prices.

Ask: Will you transfer usable in-machine and warehouse inventory at your wholesale cost as part of the sale, and will the machines be fully stocked and functional on closing day?

Red flag: Seller cannot provide a complete set of keys for every machine door and cashbox, or the card-reader accounts are in their personal name and can’t easily be transferred.

Ask: Provide a full ring of keys for every machine and a documented deactivation/reactivation process for all Nayax, Cantaloupe, or other cashless tech accounts—what is the timeline to switch merchant accounts to my name?
