Buying a Restaurant: A Beginner’s Due-Diligence Guide

The plain-English reality

Restaurants make their success highly visible and many of their problems nearly invisible. You can see a full patio. You cannot see an expiring lease, a failing walk-in cooler, unpaid sales tax, an owner working seventy hours, or a delivery channel that produces revenue without much profit. A buyer must connect what happens at the register and in the kitchen to deposits, tax filings, payroll, invoices, permits, and the actual work required to open the doors tomorrow.

How the business makes—and spends—money

• Break sales out by month, daypart, product category, location, and channel. Dining-room, takeout, catering, delivery-platform, bar, and event revenue can carry very different fees, labor, and margins.
• Calculate food and beverage cost from purchases and inventory movement, then examine waste, comps, voids, discounts, theft, portion control, and menu price changes. A single blended percentage can hide the item causing the trouble.
• Rebuild labor using the schedule the buyer will actually need. Include the seller’s shifts, management coverage, payroll taxes, benefits, overtime, training, turnover, and the possibility that key employees expect raises after a sale.
• Occupancy cost is more than base rent. Include common-area charges, insurance requirements, taxes passed through by the landlord, percentage rent, future increases, and any renovation obligation.
• Budget for merchant fees, delivery commissions, linen, grease service, pest control, music, software, licenses, repairs, smallwares, breakage, and ongoing replacement of kitchen and refrigeration equipment.
• Protect working capital. Food, payroll, rent, deposits, and repairs arrive whether the first post-closing month is strong or introduces you to every problem at once.

Records to request

Ask for original records from the bank, tax filings, payment systems, contracts, and vendors—not a prettier version of the seller’s story.

• Point-of-sale exports by month, day, daypart, category, channel, server, discount, void, comp, refund, gift card, and payment method
• Merchant statements, delivery-platform statements, bank deposits, sales-tax filings, federal tax returns, and profit-and-loss statements that reconcile to reported sales
• Vendor invoices, inventory counts, recipe or theoretical food-cost information when available, waste logs, and actual food and beverage cost by period
• Payroll registers, schedules, time records, tip reporting, employee roster, turnover, accrued paid time, benefits, and the owner’s actual shifts
• Lease and amendments covering term, options, increases, assignment, use restrictions, personal guarantees, exclusivity, maintenance responsibility, and landlord consent
• Health inspection history and every food, alcohol, entertainment, sidewalk, signage, fire, occupancy, and local operating permit relevant to the concept
• Equipment list with ownership, liens, age, service records, warranties, condition, and estimates for refrigeration, HVAC, hood, suppression, plumbing, electrical, and cooking-equipment needs
• Open gift cards, deposits, catering commitments, loyalty balances, vendor credits, tax notices, claims, customer complaints, and other obligations that may survive closing

Questions for the first serious conversation

• Can you reconcile last year’s point-of-sale sales to deposits, delivery statements, sales-tax filings, and the tax return?
• What did the owner personally do during the last four weeks, shift by shift?
• Which menu items and sales channels generate contribution after their direct food, packaging, fee, and labor costs?
• What changes at the next lease renewal, assignment, or ownership change?
• Which permits must be newly issued, approved, or transferred before the buyer can operate?
• What equipment failed or required a major repair during the last three years?
• What gift cards, deposits, catering promises, loyalty balances, tax issues, or employee obligations will remain after closing?

Red flags worth slowing down for

• Point-of-sale sales do not reconcile with deposits, sales-tax filings, delivery statements, and reported revenue
• Recent profit improvement depends on deferred repairs, reduced staffing, unpaid owner labor, or food and labor assumptions that the current operation does not support
• The lease is short, assignment is uncertain, rent resets after the sale, or the landlord expects a new guarantee or renovation
• A permit, liquor privilege, late operating hour, patio, entertainment use, or occupancy level is assumed to transfer without confirmation from the actual authority
• The seller is the chef, general manager, bookkeeper, caterer, and public face, but the SDE is presented as though all of that labor disappears at closing
• Old refrigeration, HVAC, hood, grease, plumbing, or electrical systems have little service history and no replacement allowance
• Gift cards, deposits, loyalty balances, unpaid taxes, vendor balances, or employee obligations are treated as somebody else’s problem without transaction-specific legal and accounting review

Your first-week checklist

1. Visit during a slow period, a normal service, and the busiest service. Watch ticket flow, staffing, table turns, production bottlenecks, waste, cleanliness, and management—not just the crowd.
2. Reconcile one representative month from point-of-sale detail through each payment channel, deposits, sales tax, and the accounting records.
3. Build a normalized weekly schedule showing every shift the buyer must cover after the seller leaves, then price that labor honestly.
4. Review the lease and contact the landlord through the agreed deal process before assuming the location is part of what you are buying.
5. Ask the relevant state and local authorities what a change of ownership requires. The FDA Food Code is a model; the rules that govern the restaurant come from the applicable jurisdictions.
6. Have qualified specialists inspect the building systems and major equipment, then put the near-term work into the Acquisition Quest cash-needed and downside cases.
