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

Red flag: Cash sales consistently exceed POS cash logs, or total deposits are 15%+ lower than POS sales — indicating unrecorded cash skimming or expense padding.

Ask: Can I see 12 consecutive months of daily POS closeout reports, merchant processor statements, and corresponding monthly bank deposits?

Red flag: Food cost above 35% or coffee cost above 20% with no reasonable explanation. Margins declining for 2+ quarters signals menu-pricing power erosion.

Ask: What are your monthly margins on brewed coffee, espresso drinks, food items, and retail beans separately, and can you provide a product-mix report from your POS?

Red flag: Labor running above 32%-35% without a corresponding revenue jump, suggesting overstaffing or wage pressure that cannot be passed on.

Ask: What is your total labor cost (including payroll taxes and owner draw if working) as a percentage of net revenue for the past two years?

Red flag: Total occupancy cost exceeding 10%-12% of gross revenue, or a sharp upcoming step-up in year two of a lease that re-rolls post-sale.

Ask: What are the current base rent, CAM, and real estate taxes? When was the last increase, and what does the escalation clause look like?

Red flag: Add-backs total more than 30% of recast SDE, or owner worked 60+ hours weekly with no managerial replacement, meaning the ‘profit’ is essentially a job wage.

Ask: Please provide a detailed schedule of add-backs — owner salary, family employees, personal auto, meals, etc. — and explain each.

Red flag: Machine over 10 years old without a recent major rebuild, or no service contract — a catastrophic failure will stop sales immediately.

Ask: What are the make, model, and purchase dates of the espresso machine, main grinder, ice machine, and undercounter fridges? Can I see preventive maintenance logs?

Red flag: Any ‘closure imminent’ notice, multiple repeat violations in the same category, or a score below 85 with no corrective action observable.

Ask: When was the most recent health inspection and the score? May I see the last three inspection reports and any notices of violation?

Red flag: Sole-source agreement with a roaster that has a change-of-control termination clause, or buying club membership that must be re-qualified, risking immediate supply disruption.

Ask: Who are your coffee-roaster, dairy, bread, and linens suppliers? Are there volume commitments or exclusive agreements?

Red flag: Entire staff has less than 6 months tenure, or owner is the only person who can dial-in the espresso, create the schedule, and open/close — no documented standard operating procedures.

Ask: How long have the lead barista, kitchen lead, and store manager been on payroll? Have any resignations been announced?

Red flag: An antiquated, unsupported POS with no inventory module and a loyalty program based on paper cards that no one audits — you'll need to budget $8k-$15k for a modern system.

Ask: What POS and payment processors do you use? Does the system track inventory in real-time and is there a loyalty/rewards program?

Red flag: Heavy reliance on a single day-part (e.g., 70% of sales between 7-9 AM) with no weekend or afternoon bump — extreme fragility to local office schedule changes.

Ask: Can you provide a door counter or POS hour-by-hour report for the past 12 months, and describe typical traffic by day of the week?

Red flag: A national chain (Starbucks, Dunkin', Bluestone Lane) has filed a building permit within 300 feet, or two specialty cafes opened in the last year — cannibalization is likely.

Ask: Map every existing cafe, fast-casual coffee outlet, and bakery within a 0.5-mile walk. Are there any planned entrants or construction permits?

Red flag: Rating below 4.0 on Google with a declining trend and no management responses — a sign of slipping operational standards and customer dissatisfaction.

Ask: What is the current Google Maps rating and Yelp rating, and how many new reviews have been added in the last 6 months?

Red flag: The anchor office park has a For Lease sign, or city plans show a long-term road project that will eliminate sidewalk access for 18 months.

Ask: What percentage of customers come from nearby offices, residential, or schools? Have any major employers moved, or is there a residential development pipeline?

Red flag: Landlord will not discuss assignment until after a full application, or demands a personal guarantee that doubles the security deposit. Any refusal to extend the term for at least 5 years post-closing.

Ask: Does the lease explicitly allow assignment? Has the landlord provided a written, non-binding consent framework for a qualified buyer?

Red flag: Food service establishment permit is non-transferable and health department requires a new plan-review — 60-90 days delay and risk of additional upgrades.

Ask: Which specific local health, fire, business, and sign permits are required? Are they current and transferable, or must they be reissued?

Red flag: License has conditional violations, or is a temporary catering permit tied to the seller's personal certification — can't be conveyed.

Ask: If you sell beer/wine, what type of license do you hold, is it fully paid, and what is the transfer process with the state ABC board?

Red flag: Seller operates under a handshake DBA without a registered mark, and a competitor in the same city holds a similar name that could block your use.

Ask: Is the cafe name trademarked? Do you own the logo, menu design, and proprietary recipes, and are those assets explicitly included in the sale?

Red flag: Open fire-safety violations requiring sprinkler upgrades, or a pending ADA lawsuit over bathroom accessibility.

Ask: Have you received any notices from the fire marshal, building department, or an ADA compliance demand letter in the past two years?

Red flag: Seller wants to walk away after three days, or refuses to train on the espresso station because ‘it’s easy to learn’ — no systematic recipe book exists.

Ask: How many weeks of on-site training will you provide, and at what cost? Will it cover bar flow, espresso calibration, supplier sourcing, and all recipes?

Red flag: No key employees exist, or the seller discourages you from meeting the team before closing because 'they might leave.'

Ask: Are you willing to have me introduce a retention bonus for the lead barista and manager, contingent on them staying at least 6 months post-close?

Red flag: Loyalty app is owned by the seller's personal account, or email list is on a personal Mailchimp account that won't be transferred.

Ask: Will you export and assign the full customer email list, phone numbers, and loyalty-program balances in a CSV format on closing day?

Red flag: The roaster demands a new credit application and a price increase of 15% on day one because of the ownership change.

Ask: Can you provide letters of intent from the coffee roaster, dairy, linen, and waste-hauler that they will continue service under the new entity without a price penalty?
