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

Red flag: Significant discrepancies between stated revenue/SDE and actual product sales reconciled with commission paid to locations, or a lack of granular data for each machine/location.

Ask: Can you provide detailed sales reports, by machine and location, for the past three years, along with corresponding commission statements or agreements with the location owners?

Red flag: High spoilage rates, frequent inventory write-offs, or COGS that don't align with reported sales, indicating theft or poor management.

Ask: Please detail your inventory tracking system, typical spoilage rates, and how you reconcile product purchases with sales across your route.

Red flag: Inconsistent cash deposits compared to reported sales, or significant personal expenses mixed with business accounts, blurring SDE.

Ask: Will you provide access to your business bank statements and filed tax returns for the last three years to verify reported income and expenses?

Red flag: Unusually low or high repair costs compared to the age and size of the fleet, or a sudden spike in recent repairs indicating deferred maintenance.

Ask: What is the typical annual maintenance budget for your machines, and can I review repair invoices for the past 24 months?

Red flag: Machines are 10+ years old without significant refurbishment, or a lack of remote monitoring systems causing inefficient routing and stockouts.

Ask: What is the average age of your vending machines, and can you provide purchase dates, maintenance logs, and any available telemetry reports?

Red flag: Routes are widely dispersed, requiring excessive travel time, or an inconsistent servicing schedule leading to frequent stockouts or overstocking.

Ask: Describe your current route structure and servicing schedule. What is the average daily mileage and time spent on route for each driver/operator?

Red flag: Dependence on a single, expensive supplier, or a pricing strategy that is not competitive or optimized for profit margins.

Ask: Who are your primary product suppliers, and what are your current purchasing terms? How do you determine pricing for items in your machines?

Red flag: High employee turnover, lack of documented training for route drivers/servicers, or reliance on family labor that won't transfer.

Ask: How many employees do you have, what are their roles and tenure, and what training do you provide for route servicing and machine maintenance?

Red flag: A significant portion of profitable location contracts are month-to-month, expiring within 12 months, or easily terminable by the location owner.

Ask: Can I review all current location contracts, including commission rates, term lengths, and auto-renewal clauses?

Red flag: Multiple other vending operators actively servicing the same types of locations in the immediate area, leading to price wars or difficulty in securing new spots.

Ask: Who are your main competitors in the market, and what strategies do you employ to retain locations and machines?

Red flag: All existing locations are already at maximum capacity or have expressed no interest in additional machines or product types.

Ask: Are there opportunities to place additional machines or offer different product lines (e.g., coffee, healthy snacks) at current locations?

Red flag: Declining foot traffic at major revenue-generating locations, or locations serving demographics less inclined to use vending.

Ask: How do you monitor foot traffic or employee counts at your top-performing locations, and what trends have you observed?

Red flag: Verbal agreements with location owners instead of written contracts, or excessively high commission rates eroding profitability.

Ask: Are all vending machine placements governed by written service agreements? What is the typical commission percentage paid to locations, and does it vary significantly?

Red flag: Operating without proper health or business permits in certain jurisdictions, or permits that are non-transferable.

Ask: What local, state, and federal permits or licenses are required to operate this vending business, and are they all current and transferable?

Red flag: Inadequate liability coverage for accidents or product issues, or policies that are about to lapse.

Ask: What insurance policies do you currently hold, including general liability and vehicle insurance for your service fleet?

Red flag: Any pending lawsuits related to machine malfunction, product safety, or breaches of location agreements.

Ask: Are there any current, past, or anticipated legal disputes, product liability claims, or labor issues related to the business?

Red flag: Key suppliers have expressed unwillingness to transfer accounts or offer the same terms to a new owner.

Ask: Have you initiated discussions with your primary product suppliers regarding the transfer of accounts and existing terms to a new owner?

Red flag: Key employees (e.g., skilled route drivers, maintenance staff) indicate they will leave upon sale, or seller unwilling to assist with employee training.

Ask: What is your plan to ensure a smooth transition with employees, and what level of support are you willing to provide for training the new owner or staff?

Red flag: Seller unwilling or unable to introduce the new owner to all significant location contacts, or strained relationships with key location owners.

Ask: How will you facilitate introductions and transfer relationships with all significant location owners and managers in your route?

Red flag: Lack of documentation for machine-specific programming (e.g., pricing, product selection) or technical troubleshooting guides, leaving the buyer to figure it out.

Ask: Do you have detailed documentation for machine programming, inventory management software, and common troubleshooting procedures for all equipment?
