Investing in a food business with friends is a yes only when three things are true before any money moves. You could lose all of it without blaming them. Every rule about money, pay, decisions and leaving is in a signed agreement. And you can see the bank account and the books from day one. If your friends push back on any of the three, say no and keep the friendship.
The running example is a central kitchen that needs $160,000 to open. You put in $120,000 and live in another city. Your two best friends put in $20,000 each and work there full time. Prices are US, 2026.
How likely the money is to come back
The famous "90% of restaurants fail in year one" is not true. A study by H.G. Parsa and others at Ohio State University (2005) found 26% of new restaurants closed in their first year and 60% within three years. Some of those were sold or moved, not failed. It's still high enough that you should only put in money you could give away.
A central kitchen cooks food in one place for other places to sell. Your friends' plan is one of two different businesses:
- A production kitchen cooks sauces, bread, cakes or full meals and sells them to cafés, restaurants, shops and caterers. It lives on a small number of big customers.
- A shared kitchen, also called a commissary kitchen, rents hours or stations to food trucks, caterers and home bakers. It's closer to renting out property: less food risk, but empty hours cost money.
Ask which one. If the answer is "a bit of both", ask what share of sales each one brings in year one. The rest of this article uses a production kitchen.
What the kitchen has to sell each month
Ask your friends for a plan that shows every month of the first 18 months. Here is one good month in year two of the example.
| Line | Per month | Share of sales |
|---|---|---|
| Sales to cafés and restaurants | $60,000 | 100% |
| Food and packaging | $22,800 | 38% |
| Staff wages and payroll tax | $13,000 | 21.7% |
| Your two friends' pay | $8,000 | 13.3% |
| Rent | $5,500 | 9.2% |
| Power, gas and water | $2,500 | 4.2% |
| Delivery van, fuel and insurance | $2,000 | 3.3% |
| Repairs, cleaning and trash | $1,200 | 2% |
| Accountant, software and permits | $900 | 1.5% |
| Profit | $4,100 | 6.8% |
That month makes $4,100, or $49,200 a year. Food is 38% of sales, higher than a restaurant, because a central kitchen sells at wholesale prices.
Most of these costs stay the same at $40,000 or $60,000 of sales: $33,100 a month without the food. Each $1 of sales leaves 62 cents after food. So the kitchen needs about $53,400 of sales a month ($33,100 ÷ 0.62) before anyone sees $1 of profit. One medium customer is the gap between a loss and a profit.
Before you invest, ask for the first customers by name, with letters of intent worth at least half of that: about $27,000 a month. A letter of intent is a short letter where a business says what it plans to buy, how much and from when. It isn't a contract, but a café that won't sign one rarely buys.
Also ask which friend has run a kitchen's money before, not only cooked in one. Costing recipes, ordering stock and making payroll is a different job from cooking well. If neither has done it, put a part-time bookkeeper in the plan from month one.
What's normal in a kitchen that surprises new investors
Some things look like bad news to a first-time investor and are normal in food. Others look small and are the first sign of trouble.
| What you'll see | Normal (rule of thumb) | Ask questions when |
|---|---|---|
| Monthly result in year one | A loss for the first 6 to 12 months | Still a loss in month 12 and sales aren't growing |
| Food thrown away | 4 to 10% of food bought | Over 10%, or "zero" because nobody counts |
| Real food cost against the recipes | Within 2 points | 3 points or more, two months in a row |
| Money customers owe the kitchen | About one month of sales | Any customer more than 60 days late |
| Repairs and upkeep | 1 to 2% of sales | The same machine fixed three times |
| Payouts to owners | None in year one | Owners paid while bills are late |
How much waste is normal
Leanpath, a company that measures kitchen waste, found kitchens throw away 4 to 10% of the food they buy before anyone eats it (Leanpath data shared with the US EPA, 2016). That counts trim, food that went bad, and food cooked but not sold. In the example, with $22,800 of food a month, that's $900 to $2,300 in the bin.
Trim is not the same as waste. A 50 lb case of onions gives about 45 lb once peeled, as a rule of thumb. That lost 5 lb belongs in each recipe's cost from the start.
Ask for a waste log: staff weigh what goes in the bin and write why. The reason tells you who fixes it. Too much cooked is a planning problem, food gone bad is an ordering problem, and mistakes are a training problem.
Why a kitchen with profit runs out of cash
Cafés and restaurants rarely pay on delivery. They pay on terms like "net 30", which means 30 days after the invoice. At $60,000 a month, about $60,000 is always owed to the kitchen and not in the bank.
New suppliers, on the other hand, often want cash on delivery for the first months. So a growing kitchen can show a profit and still not make payroll. Keep at least $40,000 of the $160,000 as cash for the losing months and the late payers. Spend none of it on equipment.
How to check the real sales and costs from far away
A full audit by an outside accountant costs too much for a small kitchen. Five habits give you most of the same safety.
- Get view-only logins to the business bank account and the accounting software from day one. Most banks and tools like QuickBooks Online and Xero let an owner add a user who can look but not change anything.
- Ask for a monthly pack by the 15th: profit and loss, balance sheet, bank statement and stock count. Add a list of who owes the kitchen money, and for how long.
- Match sales to the bank. A central kitchen sells by invoice, so every sale leaves a paper trail. March's invoices should arrive as April's deposits. If it also sells over a counter, every sale goes through the POS and the cash in the bank matches the POS cash total.
- Check food cost with the stock count: stock at the start of the month, plus food bought, minus stock at the end. In the example, $9,000 + $24,000 − $10,200 = $22,800, which is 38% of $60,000. If the recipes say 35%, three points are missing: $1,800 that month went to waste, theft, price rises or recipes nobody costed right. How to calculate food cost shows the recipe side.
- Once a year, pay an outside accountant (a CPA) for a "review", a lighter and cheaper check than a full audit. Put a line in the agreement that lets you send your own accountant to look at the books, at your cost.
Then step back. One 30-minute call a month, with the same five numbers: sales, food cost %, staff cost %, cash in the bank and money owed. Messages about the bins on a Tuesday night make you the boss without the job.
Owner, money back first, or a loan
Your $120,000 can go in three ways. Say the kitchen makes $49,200 a year from year two, keeps $9,200 as a cushion and pays out $40,000. In the first two deals, you own 50% and each friend owns 25%.
| 50% owner | Money back first | Loan at 8% over 7 years | |
|---|---|---|---|
| You get each year | $20,000 | $32,000, then $16,000 | $22,444 |
| Your $120,000 is back after | 6 years | About 3¾ years | 7 years, plus about $37,100 in interest |
| After that | 50% of payouts | 40% of payouts | Nothing |
| Your say in big decisions | Yes | Yes | Only what the loan papers say |
| If it closes in year two | Paid last, usually nothing | Paid last, usually nothing | Paid before owners, if anything is left |
Money back first is the fairest deal for a friend who only puts in money. You take 80% of payouts until your $120,000 is back, then your share drops to 40%. Your friends earn less early and more later. That matches who took the risk and who does the work.
A loan keeps you out of the business, but its $1,870 a month is due in the losing months too. If you lend, start the payments after month 12. Never ask your friends to sign for the loan personally. That turns a closed kitchen into a debt between friends.
Where investing in a food business with friends goes wrong
Most fights between friends who own a kitchen are about four things. Each one needs a line in the agreement.
Pay against profit
Your friends work 60 hours a week for $4,000 a month each. You live in another city and own half the profit. By month 18, someone feels they do all the work for half the money.
Set their pay now at what a job ad in their city offers for the same work, and review it at month 12. Their pay is a cost paid before profit. So a raise for them is less money for you. Agree the rule for raises now, while everyone is happy.
More money
A walk-in fridge breaks, the first winter is slow, a customer pays 90 days late. Your friends will ask you first, because you're the one with money. Write the most you'll ever put in: "$120,000, and nothing more unless I choose to." Also write down what happens when one owner adds money and the others don't: that owner's share grows, by a formula you agree today.
One friend leaves
In year two, one friend gets a job offer, has a baby, or simply burns out. Without a rule, they keep 25% of the kitchen for no work. The fix is vesting: each friend earns their share over four years. One who leaves after a year keeps a quarter of it, and the business can buy that back at a set price.
The investor who can't stay out
You're money only, so the daily calls are theirs: menu, staff, suppliers and prices. Write which decisions need your yes: spending over $5,000 at once, any new loan, any new owner, owners' pay, selling and closing. Everything else is theirs, and you don't comment on it.
What to write down before any money moves
An LLC's operating agreement is the paper that holds all of this. It's the rule book between the owners. Put in:
- Who puts in how much, and by what date. "Might put in money" is not a number.
- Each owner's share, and how the working owners' shares vest over four years.
- The working owners' pay, and when it's reviewed.
- How profit is paid out, including money back first if you choose it, and a yearly payout to cover tax.
- Which decisions need every owner's yes, and how a tie is broken.
- The most each owner will ever put in, and what happens to shares when someone adds more.
- Who signs personally for the lease or loans, and for how much.
- What happens when an owner leaves, dies, divorces or can't work: who can buy the share, and the price formula.
- The closing plan: for example, sales under $40,000 a month in month 12 means you close, sell the equipment and pay everyone in order.
- Your right to see the books, and the date of the monthly pack.
If anyone refuses to put something on paper, that's your answer: don't invest. The lawyer who writes the agreement works for the business, not for you. Pay your own lawyer for an hour to read it before you sign.
US rules for an investor in a central kitchen (2026)
No paperwork means a partnership
In most states, two or more people who run a business for profit together, with no company formed, are a general partnership by law. Each partner can be made to pay all of the business's debts personally, even debts another partner signed for. Form an LLC (limited liability company) with your state's Secretary of State before any money moves. Your loss then stops at what you put in, except for anything you sign personally.
Tax on money you never got
An LLC with more than one owner is taxed like a partnership unless it chooses otherwise. Each year you get a Schedule K-1 (Form 1065). You pay income tax on your share of the profit, even if the kitchen kept the cash. With a straight 50% share, that's $24,600 of income on your tax return, even if only $20,000 reached you. The yearly tax payout in the agreement covers this.
As an owner who doesn't work in the business, your share of early losses is usually a passive loss (IRS Publication 925). You can use it against other passive income, not against your salary. Ask your accountant how it works for you.
Signing personally for loans
Landlords and banks often ask every owner to sign personally. For SBA 7(a) loans, every owner of 20% or more signs an unlimited personal guarantee (SBA SOP 50 10 8, since June 1, 2025). That puts your own savings and home behind the kitchen's loan. Know this before you take 20% or more of a kitchen that plans to borrow.
Licenses a central kitchen needs
A central kitchen that sells to other businesses is not a restaurant under FDA rules (21 CFR 1.227). It usually has to register with the FDA as a food facility. Registration is free and is renewed between October 1 and December 31 of every even year, 2026 included.
Selling wholesale often needs a state license from the department of agriculture or health. Meat and poultry products sold to other businesses often need USDA inspection. Rules differ by state, so check with your local health department and state department of agriculture before anyone signs a lease.
Do this week
- Ask your friends in writing which kind of central kitchen it is, and how much each of them puts in, by what date.
- Ask for the plan for the first 18 months, month by month, and the names of first customers worth half the break-even sales.
- Decide the most you'll ever put in, and whether you could lose all of it without blaming them. If not, put in less or say no.
- Pick the deal (owner, money back first or loan) and send your friends the list above before anyone pays a lawyer.
- Book an hour with your own lawyer to read the operating agreement before you sign.
