Are you a micro business? You might be if you:

  • Employ fewer than 10 people.
  • Often operate out of a single location or remotely.
  • Typically have less than $250,000 in annual sales (though standards can vary by industry).

And whether you identify as a solopreneur, freelancer, side hustler, or small-business owner, there are unique challenges micro businesses face and specific solutions that are needed to move the business forward.

There are many successful micro businesses in the United States. Indeed, of the more than 36 million small businesses in the United States, the vast majority of them have fewer than 10 employees. Indeed, micro businesses make up about three-quarters of all employers.

Micro businesses are a great way to satisfy an entrepreneurial spirit. They typically have smaller startup costs, allow for greater decision-making flexibility, and cater to a specific market niche.

However, sales and marketing, raising capital, and managing operations with a small staff can make running a micro business a challenge.

Here are 10 tips that may help strengthen and support your micro business.

Finance and micro business funding tips

1. Become creditworthy: Regardless of the bank you choose, becoming creditworthy is important for gaining access to capital through micro business loans. Keep in mind the 6 C’s of lending: character, cash flow, capital, collateral, capacity, and conditions. And remember — lenders could want owners to contribute at least 25 percent of the capital and will usually need to see cash flow equal to 1.3 times the debt.

2. Seek out alternative sources of funding: If you can’t get — or don’t want — a traditional bank loan, crowdfunding or getting a Community Development Financial Institution (CDFI) loan could be an option. CDFIs cater specifically to underserved entrepreneurs in low-income communities.

3. Manage cash flow: Managing how much money comes in versus how much goes out is essential for every business. It is especially important to grow a micro business on a budget. To do this, it helps to forecast expenses and earnings, create a cash flow budget, and improve inventory management by keeping your record-keeping up to date. Additionally, some business owners maintain a small cash reserve — about one to three months of operating expenses — that can be a buffer during unexpected slow periods.

Structure and operations tips

4. Choose the right entity structure for your business: Choosing the right structure for your business is a critical decision that will affect many things. Whether you become a sole proprietorship, S or C-corporation, LLC, or partnership, the type of business entity should depend on three main factors: liability, taxation, and record-keeping requirements.

5. Separate your personal and business finances: While it may seem easier to keep your personal and business funds in one account, it’s much smarter to keep them apart. This allows you to easily track your cash flow, make your accounting more efficient, take advantage of tax deductions, and protect yourself from liability. (See also: Self-employed?

6. Use digital and AI tools to help complete tasks: Handling several jobs at once can often be difficult for a small team. To automate and streamline many of these tasks, use digital tools, including accounting software, project management platforms, and point-of-sale systems with inventory management features. And in the last two years, AI-powered productivity tools for small teams have become a significant and growing resource.

Marketing and growth tips

7. Stick to a low-cost marketing plan to attract customers: With social media marketing and other forms of digital advertising, micro-business owners no longer need enterprise-level marketing budgets to promote their businesses. And most modern digital marketing tools are simple and intuitive to use.

8. Know your ratios: There are several ratios that all micro-business owners should be aware of: employees per square foot, sales per square foot, and revenue per employee. Learning these may helpyou streamline your business, evaluate cash flow, and monitor financial performance. (Related: 6 ratios a business owner should track)

Protection and support tips

9. Protect yourself and the business: As a micro-business owner, your business often depends entirely on you. If things take an unexpected turn, it’s good to ensure that you and everyone who depends on you — family, employees, and customers — are covered. This is where life insurance and disability income insurance can help entrepreneurs, along with standard business liability protections.
