Is there a statutory number of diligence days?
No. Length is negotiated in the LOI. Grocery files need enough calendar to recast SDE, tie scan to deposits, abstract the lease, and list every permit. Alcohol and assignment fights add weeks.
Put the diligence period in the LOI with a list of what gets opened, then book a confidential intro if you need a realistic calendar for this box. Grocery due diligence is weeks, not an afternoon. Alcohol, a messy lease, or a recast that will not tie to deposits will add more weeks. Two weeks of looking only at tax returns is not grocery diligence.
The longer walk-through is surviving due diligence. This page is the clock: what starts the weeks, what stretches them, and when to stop.
Grocery diligence is a calendar, not a folder
Due diligence is the buyer’s investigation of financials, scan data, lease, licenses, equipment, employees, and environmental issues. On a grocery file the heavy items are inventory method, EBT settlements, wholesaler statements, and whether add-backs are really shrink. FMI’s 2.1% average food-retailer net profit for 2025 is why those items matter: a small miss in margin or occupancy erases the year. That Speaks figure is a food-retailer sample, not your independent’s quote.
Price still waits on a recast. BizBuySell’s grocery/supermarket sold sample averaged a 3.38 earnings multiple in 2025, with a 2021–2025 IQR of 1.60–3.15. Diligence is how you decide whether this store belongs in that band or below it. A CIM that omits the lease abstract is a brochure. A period that expires before the wholesaler has spoken is a setup for a re-trade.
Sellers want a short clock because confidentiality leaks: employees learn from vendors and shoppers. Buyers want a long clock because grocery has more agencies than a dry retailer. The fair period is the shortest calendar that still opens the real files. Write that list. Do not rent an open-ended fishing trip.
What actually gets opened in week one
Start with three years of P&Ls and returns if they exist, weekly sales by department, bank deposits, merchant statements, and the recast bridge. Tie scan data to deposits and, where food is taxed or partially taxed, to sales-tax filings. See how to verify grocery store sales and evaluating a store’s P&L. Department gross margin hides in a storewide blend; meat and produce can sink a “healthy” number. Turns are not one number — center store and wine do not share a clock.
Open the lease the same week. Assignment, exclusive use, co-tenancy, remaining term, options, and CAM. A below-market related-party rent juiced earnings and will reverse on day one. See how to evaluate the lease. Occupancy as a percent of sales is the first underwriting check on a neighborhood box; do not borrow supermarket weekly-sales figures for a 5,000–12,000 square foot store.
List SNAP, alcohol, food, WIC, tobacco, and lottery. USDA FNS: SNAP authorization does not transfer; the new owner files a new application for the location and owners on record. Diligence is not the FNS decision. Diligence is whether the mix is real, whether the buyer can fund a gap, and whether the landlord will live through it. Read EBT and SNAP diligence.
Read the wholesaler agreement for personal guarantees, over-advances, drop minimums, and banner fees. Those fees belong in the recast as continuing costs if the buyer keeps the fascia. DSD vendors will keep delivering after a sloppy close only if someone is paying them.
Why alcohol and leases stretch the clock
NABCA lists seventeen control states (eighteen control jurisdictions when counting Montgomery County, Maryland). In those states grocery wine or spirits, if allowed at all, run through the control authority. In license states the alcohol agency still has to approve the incoming licensee. Quota or series licenses can have market value and a waiting list. Local wet/dry rules can bar the privilege entirely. Counsel who has never closed a grocery file will treat “the liquor license” as one exhibit. It is not. See liquor transfer.
Landlord silence stretches weeks. Some landlords want financials, a use statement, and a personal guarantee from the incoming owner. Some will not assign at all. Write a date by which assignment must be in process, and a walk right if it is not. Tax clearance and successor-liability practice can still exist after UCC Article 6 died; ask the revenue agency, do not assume a handshake. Owned real estate is a second asset and a second diligence track: recast the store on market rent, then underwrite the building.
WARN and union contracts are calendar items on larger headcount files. Most single-store independents are not WARN-covered; multi-store or UFCW shops might be. Confirm headcount before ignoring it.
Financing, inventory rules, and when to stop
SBA 7(a) can fund a change of ownership. The maximum 7(a) loan amount is $5 million. The borrower still has to be a for-profit U.S. business that is small under SBA size rules, not an ineligible type, unable to obtain desired credit on reasonable terms elsewhere, and creditworthy with a reasonable ability to repay. That underwriting runs on documented cash flow. Seller notes often sit on standby behind SBA; read the standby. DSCR is annual cash flow over annual debt service. Hope is not a ratio.
Inventory night is not diligence, but the rules belong in the LOI during diligence: unsellable goods, who pays the crew, how disputes resolve. Earn-outs on grocery are hard because the buyer controls mix after Monday. Distressed stores still have inventory and a lease; price those, not a turnaround novel.
Stop when the numbers will not tie, the landlord will not assign, the wholesaler will not onboard, or the license calendar cannot be funded. Comparing offers means cash at close, note terms, inventory treatment, and license risk — not the headline price. A rural box can be a good living and a terrible loan; finish diligence knowing which question you asked.
Book a confidential intro with the week-one stack: P&Ls, weekly sales, lease, licenses, wholesaler page. Jason Taken at Grocery Store Business Broker (HedgeStone Business Advisors) will tell you whether your LOI period is a plan or a wish. If the stack is not ready, use the call to name what is missing so the period you write is a calendar you can keep. Read how a sale works so the diligence weeks sit on a real close path.
An illustrative recast on How long does due diligence take?
Use this napkin recast on How long does due diligence take? when you book the call. It is labeled illustrative. BizBuySell's 2025 grocery sold-business earnings multiple averaged 3.38, with a 2021-2025 IQR of 1.60-3.15.
| Input or output | Illustrative figure |
|---|---|
| Weekly sales (illustrative) | $195,000 |
| Annual sales | $10,140,000 |
| Recast SDE | $476,580 (4.7% of sales) |
| Inventory at cost | $633,750 (~16 turns) |
| Occupancy check | $365,040 / year (3.6% of sales) |
| Low going-concern | $1,515,423 at 1.85x SDE + inventory |
| High going-concern | $2,063,490 at 3.00x SDE + inventory |
| Sketch DSCR on a note | 1.52 |
If weekly sales or shrink move 8 percent, the SDE and the note move with them. That is why Jason Taken starts with scan data and the lease, not with a neighbor's rumor multiple.
Book the intro call with your side of the table ready: seller files or buyer capital. The calendar is the only next step.
