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

Red flag: Lack of detailed sales data per machine or discrepancies between sales reports and bank deposits/commission statements.

Ask: Can you provide detailed sales reports for each machine, including product mix and average daily vends, corroborated by bank statements and commission payments from location owners for the past 24-36 months?

Red flag: High spoilage rates, inconsistent inventory counts, or COGS percentages that fluctuate wildly without explanation.

Ask: Please provide your inventory purchase logs, current inventory valuation, and explain your process for tracking inventory usage, spoilage, and how COGS is calculated.

Red flag: Multiple locations showing negative or marginally positive profitability after accounting for commissions, labor, and travel.

Ask: Can you provide a profitability breakdown for each vending location, detailing revenue, commissions, product costs, and estimated operational expenses?

Red flag: A sudden drop in maintenance expenses in the most recent period, suggesting deferred upkeep, or excessively high consistent repair costs for specific machines.

Ask: Please provide a detailed report of all maintenance and repair expenses, broken down by machine, for the last three years, including service provider invoices.

Red flag: High credit card processing fees as a percentage of sales, or significant chargeback issues.

Ask: What are your total credit card processing fees and chargeback rates, and how do these compare to your overall sales volume?

Red flag: A significant portion of machines are older than 10-12 years, frequently out of service, or lack modern payment/telemetry systems.

Ask: Can you provide a detailed equipment list, including manufacturer, model, year of manufacture, last major service date, and whether each machine is equipped with cashless payment or telemetry systems?

Red flag: Routes are highly dispersed geographically, leading to excessive travel times and fuel costs for refilling and maintenance.

Ask: Describe your typical route scheduling and logistics. How many machines are serviced per route, what is the average time between refills for each machine, and what are the daily/weekly travel distances?

Red flag: Sole reliance on a single, expensive supplier, or no established, competitive pricing agreements with major distributors.

Ask: Who are your primary product suppliers, what are the current terms of your purchase agreements, and when do these agreements expire?

Red flag: High employee turnover, lack of documented training protocols, or reliance on inexperienced part-time staff for critical operational tasks.

Ask: If you have employees, please describe the current staffing structure, their roles, tenure, and any training or certification they have received relevant to vending operations.

Red flag: A large percentage of location contracts are short-term, month-to-month, or expiring within the next 12-18 months without renewal options.

Ask: Please provide copies of all current location contracts, highlighting the duration, renewal clauses, and any exclusivity provisions.

Red flag: Other vending operators or alternative food/beverage options (e.g., cafeterias, micro-markets) are present in the same locations, indicating intense competition.

Ask: Who are your primary competitors in your key locations, and what efforts have you made to retain your market share or differentiate your offerings?

Red flag: Key locations are in declining industries, seeing reduced employee counts, or exhibiting significantly decreased foot traffic post-pandemic.

Ask: Can you share data or insights regarding the foot traffic, employee population, or customer base demographics for your top 10-15 revenue-generating locations?

Red flag: The current product mix heavily relies on declining categories or fails to incorporate healthier/specialty options that are gaining market share.

Ask: What are the current product bestsellers across your machines, and how do you monitor and adapt your product selection to changing consumer preferences and market trends?

Red flag: Location agreements explicitly state non-assignability or require arduous consent processes from location owners for transfer.

Ask: Are all existing location agreements assignable to a new owner, and what is the typical process for obtaining consent from location partners for a change of ownership?

Red flag: Evidence of past or ongoing legal disputes with location owners, suppliers, or employees.

Ask: Have there ever been any legal disputes, claims of breach of contract from location partners or suppliers, or regulatory violations related to your vending operations?

Red flag: Missing or expired operating permits, or a history of health code violations related to food handling or machine cleanliness. (Less common for ambient/non-food, but critical for chilled/fresh options).

Ask: What permits and licenses are required to operate this vending business, and can you provide documentation of current compliance and past inspection reports?

Red flag: Insufficient liability insurance coverage for the scale of operations or a history of numerous claims for property damage or personal injury.

Ask: What type of business insurance do you carry (e.g., general liability, property, auto), and have there been any significant claims filed in the last five years related to your vending operations?

Red flag: Seller is unwilling or unable to facilitate personal introductions to critical location owners and decision-makers.

Ask: What is your plan for introducing me to all key location owners and decision-makers to ensure a smooth transition of the business relationship?

Red flag: Seller lacks organized records of logins, passwords, and accounts for machine telemetry, cashless payment systems, or inventory management software.

Ask: How will the transfer of all digital accounts, including telemetry platforms, cashless payment systems, and any route management software, be documented and executed securely?

Red flag: Seller offers minimal post-sale training on the daily mechanics of route management, inventory loading, or basic machine maintenance/troubleshooting.

Ask: What level of training and support are you prepared to offer post-acquisition to familiarize me with the daily route operations, inventory processes, and common machine maintenance tasks?

Red flag: Seller has no plan for introducing the buyer to key suppliers or ensuring continuity of supply agreements and pricing initially.

Ask: How will you facilitate the transfer of supplier accounts, and can you assist with placing initial product orders under the new ownership to ensure continuity?
