After years of researching the perfect idea for a business, Oren Bloostein had finally created a solid business plan for a specialty coffee shop on the Upper East Side of New York City called Oren's Daily Roast. But like most entrepreneurs, he was soon faced with the daunting challenge of financing it. So, in addition to $30,000 of his own savings, his parents gave him $50,000, and he got a bank loan for $25,000, which his parents also guaranteed.

From that point forward, his parents would play a significant role in the company's growth.

"I started the company in 1986, but it took almost a decade before I could borrow using assets from the business. The first eight years of expansion, which included six more stores and a factory, the loans were all guaranteed by my parents' assets," says Bloostein. "But the lines were clear. My parents weren't part owners, but my dad and I would have regular meetings, at which I would present him the numbers, projections, revenue, and everything."

His savvy approach helped his company become what it is today—a nearly $10 million business with nine locations in Manhattan. The moral of the story? Mom and Dad can be a great source of financing, but there's a right way (and a very wrong way) to approach that initial conversation about money. 

"Almost 90 percent of the small businesses in this country are family-owned, so it's no surprise that the first place entrepreneurs turn for financing is the family," says Tom Deans, family business expert and author of Every Family's Business.

Of course, the personal dynamic between parent and child can pose rather unique obstacles when it comes to financial agreements for a small business venture. In Laymen's terms: Beware of drama.

"Families run on a value system of democracy and transparency," says Deans. "The value system of a business, however, is based on hierarchy and meritocracy. They naturally clash. But there are steps you can take beforehand that can make the merger work."

Here are a few things to consider to make that first sit down with Mom and Dad as drama-free as possible. 

Avoid casual conversations.  Keep quiet about your brilliant business idea until you have a fully developed business plan. Deans says this seems like common sense, but too often that carefree, casual relationship you have with your parents can cause confusion later on. Wayne Rivers, president of the Family Business Institute agrees. "It's the lack of formality in these informal conversations get people in trouble," he says. "You can end up making promises you won't want to—or can't—keep later on." For Bloostein, the financing sit-down didn't happen right away. "I had been working on a business plan for almost six years," he says. Though his parents knew of his small business ambition, it wasn't until he had a virtually "no-risk" plan that any money talk began.

Vet your business plan. Rivers says you should not only have a sound business plan, but a third party should vet it. "There's so many services online where you can have experts evaluate your plan," he says. "Give your parents, and yourself for that matter, the peace of mind that this business will be a sound investment, and not just another hobby." A good place to start is the U.S. Small Business Administration's list of local resources.

Write a promissory note.  If you are asking for a loan from your parents, both experts suggest drafting a promissory note, or a simple document that outlines the terms of the loan. This will answer your parents knee-jerk questions: "How will you pay us back, what will the interest rate be, and how long will it take to repay in full?" It will also prevent any confusion later on. "Be as specific as possible in the note," adds Rivers. "You don't want to have a conversation about how you promised to pay back the money in two months and there's no written record of it."

The early inheritance option. If your parents are of means, you could also ask for early inheritance.  "I am actually a big proponent of parents giving their kids wealth," says Deans. "The money is forwarded to the kid while they are still alive. There's an element of reward for the parents to see their legacy put to good use while they're alive." But Deans suggests that this arrangement should most definitely be written into a legal contract.

Consider your siblings. Whether a loan or gift, remember that you are tapping into the family reserve—and your siblings might not like it. "If the parents are going to loan one kid $20,000, do the other kids get the same bite of the apple?" asks Rivers. "Or if the parents are of modest means, and one child wipes out all the savings, what happens to everyone else? You can't have the black sheep brother wiping out the family farm on a failed business venture."  Deans suggests bringing the siblings into the initial conversation. "It will show your parents that you are serious, and show your siblings it isn't a rivalry," he says.

Get a small traditional bank loan, too. This might sound a little strange, but  Deans says that going to a traditional lender for just a small loan can go a long way if your parents will be the larger investor. "If you can secure a small loan first, your parents, who are more likely to extend money based on good will, immediately have a sense of comfort that your idea is sound investment," he says. "The traditional lender will have looked at the business plan, executed the due diligence, and given the business a thumbs up."

Have a plan for future meetings. Both experts agree that managing transparency is key in keeping the peace between family and the business. Like Bloostein, work out a meeting schedule that works for you, your parents, and your business. And have this meeting schedule in place from the beginning, telling them how often they will get updates on how the business is doing and—more importantly—how their money is doing. Laying out the terms for the professional interactions in the first conversation will provide a less stressful framework from which you can go forward. "It doesn't have to be a daily conversation," says Rivers. "Set up quarterly, or semi-annual meetings where you will share the status of your business. Just something to give everyone a structure."

Finally, remember the other relationship at play. That is, the relationship between your parents and their money. Are they likely to finance this type of thing? Have they done it before? Can they handle the financial demands?  "Remember, just because they are your parents, doesn't mean they have to say yes," says Rivers.
