You Just Inherited a Restaurant: The First 30 Days of Numbers You Need to Pull

You didn’t choose this, but the clock started anyway

Maybe it was a parent who passed. Maybe it was a relative who got sick and handed you the keys with a shrug. Either way, nobody sat you down with a P&L and walked you through it. You’re standing in a restaurant that suddenly has your name on the lease, and you don’t know if it’s making money or bleeding it.

Here’s the good news, friends: you don’t need an accounting degree for the next 30 days. You need a sequence. Don’t fire anyone yet. Don’t change the menu yet. Don’t panic-sell yet. Pull the numbers first. Every decision you make before you have them is a guess dressed up as a decision.

Get the three numbers before you decide anything

There are three numbers every operator has to know: AOV (average order value), prime cost (a 25/25/25 rule of thumb, roughly 25% to COGS, 25% to labor, 25% to rent and overhead), and burn rate (what the place costs out of pocket every month even at zero sales). If you can’t say all three out loud right now, you’re flying blind, and right now, you are.

Restaurant margins run 3 to 5% in a good year. There’s no cushion for guessing. I’ve seen ice cream selling like crazy at 720 Sweets while the bank account sat at $1,000, sometimes negative. Sales and profitability are not the same thing, and you can’t tell them apart without these three numbers. Pull the last 90 days of bank statements and the last three POS reports before you do anything else. That’s your starting line.

While you’re in there, check where daily traffic actually sits. A full-service restaurant needs roughly 50 covers a day at a $35 average ticket to break even in today’s cost environment. Pull the register report for the last 30 days and see where this place lands against that line. That single comparison tells you more than a stack of tax returns.

Watch the repeat customer trend before you touch marketing or menu

Once you have the three numbers, look at repeat customer rate, week over week. Not the level, the trend. Three weeks of decline is the one signal that should stop everything else and force a hard look at the concept itself.

Here’s why this matters more than anything on the P&L: the P&L lags by 30 to 60 days. By the time it tells you there’s a problem, the problem is two months old. Repeat rate moves first. I had a consulting client whose numbers looked fine for 90 days while their repeat rate had been sliding since week two. They were pouring money into new customers the whole time while old ones quietly stopped coming back. The acquisition wasn’t broken. The bucket had a hole in it. If repeat rate is falling in the business you just inherited, don’t spend a dollar on marketing until you know why people stopped coming back.

Find out if the business runs without the person who used to run it

Ask yourself one blunt question: can this place survive two weeks without the person who used to run it? If the answer is no, you haven’t inherited a business. You’ve inherited a job that happened to have someone else’s name on it.

Check for a written system. Does anyone besides the previous owner know the full sequence for every station? Was there a manager who actually ran the floor, or did everything route through one person’s head? If nothing is written down and everything lived in someone’s memory, that’s your first real project. Systems are what let two drinks get made every minute at scale. Without them, you don’t have a business you can leave the building. You have a business that will collapse the day you take a sick day.

Look at who’s stayed, and treat that as your biggest asset

Annual turnover in restaurants commonly runs above 75%, and over 100% in fast food. Whoever is still on your payroll after all that churn already survived the filter. Replacing an hourly hire costs roughly one to two months of that role’s wages once you count advertising, training, and lost productivity, and a brand-new hire runs at about 25% output in month one while earning full wage. The people who stayed are not overhead. They’re the asset that kept this place standing while nobody was steering it. Talk to them before you touch a single schedule. You can teach skill. You can’t teach the care they’ve already shown by staying.

Count the menu before you touch the price

Pull every item that sold in the last 30 days and rank it by volume. You will almost certainly find a long tail of items that sell once a week and eat prep time, inventory dollars, and kitchen attention every single day. The fewer things a kitchen sells, the better it sells them. In-N-Out runs four items and outsells a McDonald’s roughly 2 to 1 per store. That’s not a limitation. That’s the whole moat.

Don’t raise prices yet. First cut the dead weight, then look at bundling top sellers to push AOV up without chasing a single new customer. A well-built bundle can turn a single-item order into a ticket two or three times the size. Do this before you spend anything on marketing. A confused menu will eat any ad budget you throw at it.

Day 30: keep, fix, or sell

By day 30 you have your three numbers, a repeat rate trend, a systems answer, a staff read, and a menu audit. Now ask the real question: does this concept fit your actual life? Full-service restaurants run late hours and heavy headcount. Some concepts hide the hard work in prep, some in service, some in staffing. The spreadsheet math was never the previous owner’s biggest problem or yours. The calendar math is. If the hours, the skill ceiling, and the capital this place demands don’t line up with the life you actually have, the honest move is to fix it enough to sell it well, not to grind through years you don’t want. If they do line up, you now have something rare: a running business, real numbers, and 30 days of clarity nobody handed you. You built that yourself.
