STEP 1: Plan your business

A clear plan is essential for success as an entrepreneur. It will help you map out the specifics of your business and discover some unknowns. A few important topics to consider are:

Luckily we have done a lot of this research for you.

What will you name your business?

Choosing the right name is important and challenging. If you don’t already have a name in mind, visit our How to Name a Business guide or get help brainstorming a name with our Advertising Agency Name Generator

If you operate a sole proprietorship, you might want to operate under a business name other than your own name. Visit our DBA guide to learn more.

When registering a business name, we recommend researching your business name by checking:

  • Your state's business records
  • Federal and state trademark records
  • Social media platforms
  • Web domain availability.

It's very important to secure your domain name before someone else does.

What are the costs involved in opening an advertising agency?

Since advertising agencies provide services rather than products, the startup costs of starting an agency are minimal. Ideally, agencies should have an office for meeting clients, computers for working on projects, an internet connection and a printer for printing any physical marketing collateral. Agencies also need a website.

There are ways of keeping rent, computer costs, internet access and utilities, and printer costs extremely low, though. Business owners who are operating on a tight budget can:

  • Rent an office on an as-needed basis
  • Work in coffee shops that offer free Wi-Fi
  • Use a personal computer they already own
  • Outsource any printing to a local print shop

If necessary, business owners can even meet clients in coffee shops -- thus limiting the startup costs to little more than a website and a few lattes. (Any printing costs can be paid after a client has made a deposit for a project.)

What are the ongoing expenses for an advertising agency?

The ongoing expenses for an advertising agency include rent for an office (if the agency has one), computer costs, internet access fees and employees’ salaries. Employees’ salaries are typically the largest ongoing expense for an agency.

Who is the target market?

Advertising agency's clients are most often other businesses, corporations or non-profit organizations. A particular agency’s ideal client will be one that is within an agency’s marketing niche and needs ongoing work. Often, such a client will ask to place an agency on retainer. (A retainer is an arrangement where a client pays an agency a consistent amount each week or month and, in exchange, the agency sets aside a certain number of hours each period to work on the client’s campaigns.)

How does an advertising agency make money?

An advertising agency makes money by charging clients for creating and planning advertising campaigns. In most situations, an agency will pitch a potential client without being compensated. If the client likes the pitch, the agency is contracted to execute their proposed campaign.

How much can you charge customers?

Advertising agencies often charge clients either an hourly fee or a commission. According to Two Hats Consulting & Web Design Services, hourly fees are typically calculated by dividing the annual salary of the person (or people) who will work on a project by 1,500 (the number of billable hours a typical person might work in a year). Commissions are traditionally 15 percent of all media and production charges.

How much profit can an advertising agency make?

As mentioned above, advertising agencies can bring in billions of dollars annually, but most have much lower annual revenues. Many agencies bring in tens or hundreds of thousands annually, depending on their niche and distinctives. It’s not unheard of to achieve millions in annual revenue, though.

How can you make your business more profitable?

An advertising agency can increase its profitability by offering services in addition to traditional marketing. For example, an agency might provide clients with public relations or social media consulting services if either of these are needed.

STEP 2: Form a legal entity

The most common business structure types are the sole proprietorship, partnership, limited liability company (LLC), and corporation.

Establishing a legal business entity such as an LLC or corporation protects you from being held personally liable if your advertising agency is sued.

Form Your LLC

Have a Professional Service Form your LLC for You

Two such reliable services:

You can form an LLC yourself and pay only the minimal state LLC costs or hire one of the Best LLC Services for a small, additional fee.

Recommended: You will need to elect a registered agent for your LLC. LLC formation packages usually include a free year of registered agent services. You can choose to hire a registered agent or act as your own.

STEP 3: Register for taxes

You will need to register for a variety of state and federal taxes before you can open for business.

In order to register for taxes you will need to apply for an EIN. It's really easy and free!

You can acquire your EIN through the IRS website. If you would like to learn more about EINs, read our article, What is an EIN?

There are specific state taxes that might apply to your business. Learn more about state sales tax and franchise taxes in our state sales tax guides.

STEP 4: Open a business bank account & credit card

Using dedicated business banking and credit accounts is essential for personal asset protection.

When your personal and business accounts are mixed, your personal assets (your home, car, and other valuables) are at risk in the event your business is sued. In business law, this is referred to as piercing your corporate veil.

Open a business bank account

Besides being a requirement when applying for business loans, opening a business bank account:

  • Separates your personal assets from your company's assets, which is necessary for personal asset protection.
  • Makes accounting and tax filing easier.

Recommended: Read our Best Banks for Small Business review to find the best national bank or credit union.

Get a business credit card

Getting a business credit card helps you:

  • Separate personal and business expenses by putting your business' expenses all in one place.
  • Build your company's credit history, which can be useful to raise money later on.

Recommended: Apply for an easy approval business credit card from BILL and build your business credit quickly.

STEP 5: Set up business accounting

Recording your various expenses and sources of income is critical to understanding the financial performance of your business. Keeping accurate and detailed accounts also greatly simplifies your annual tax filing.

STEP 6: Obtain necessary permits and licenses

Failure to acquire necessary permits and licenses can result in hefty fines, or even cause your business to be shut down.

Federal Business Licensing Requirements

Known as “truth-in-advertising” laws, these regulations protect consumers by requiring advertisers to be truthful about their products and to be able to substantiate their claims. All businesses must comply with advertising and marketing laws, and failure to do so could result in costly lawsuits and civil penalties.

The Federal Trade Commission (FTC) is the main federal agency that enforces advertising laws and regulations.

State & Local Business Licensing Requirements

Certain state permits and licenses may be needed to operate an ad agency. Learn more about licensing requirements in your state by visiting SBA’s reference to state licenses and permits.

Most businesses are required to collect sales tax on the goods or services they provide. To learn more about how sales tax will affect your business, read our article, Sales Tax for Small Businesses.

Services Contract

In business where services are provided on an extended basis, a services contract is often put in place outlining terms and conditions of service. You may wish to require clients to sign a services agreement before starting a new project. This agreement clarifies client expectations and minimizes risk of legal disputes by setting out payment terms and conditions, and service level expectations. Here is an example of one such services contract.

Certificate of Occupancy

An advertising agency is generally run out of a storefront. Businesses operating out of a physical location typically require a Certificate of Occupancy (CO).  A CO confirms that all building codes, zoning laws and government regulations have been met.

  • If you plan to lease office space:
    • It is generally the landlord’s responsibility to obtain a CO.
    • Before leasing, confirm that your landlord has or can obtain a valid CO that is applicable to an advertising agency.
    • After a major renovation, a new CO often needs to be issued. If your place of business will be renovated before opening, it is recommended to include language in your lease agreement stating that lease payments will not commence until a valid CO is issued.
  • If you plan to purchase or build office space:
    • You will be responsible for obtaining a valid CO from a local government authority.
    • Review all building codes and zoning requirements for you business’ location to ensure your advertising agency will be in compliance and able to obtain a CO.

STEP 7: Get business insurance

Just as with licenses and permits, your business needs insurance in order to operate safely and lawfully. Business Insurance protects your company’s financial wellbeing in the event of a covered loss.

There are several types of insurance policies created for different types of businesses with different risks. If you’re unsure of the types of risks that your business may face, begin with General Liability Insurance. This is the most common coverage that small businesses need, so it’s a great place to start for your business.

Another notable insurance policy that many businesses need is Workers’ Compensation Insurance. If your business will have employees, it’s a good chance that your state will require you to carry Workers' Compensation Coverage.

FInd out what types of insurance your Advertising Agency needs and how much it will cost you by reading our guide Business Insurance for Advertising Agency.

STEP 8: Define your brand

Your brand is what your company stands for, as well as how your business is perceived by the public. A strong brand will help your business stand out from competitors.

How to promote & market an advertising agency

Where an advertising agency should place advertisements depends on the types of clients it hopes to attract. For instance, an agency that targets local businesses may want to place advertisements in the area’s newspapers and join the town’s chamber of commerce. In contrast, an agency that focuses on marketing online may be better off using pay-per-click campaigns online.

How to keep customers coming back

An advertising agency can set itself apart from others by winning awards for campaigns it completes. There are many groups that offer awards for various advertising projects. Hermes Creative Awards, Ad Age’s Small Agency Awards, Marcom Awards and Clio Awards are just a few organizations that offer advertising awards.

STEP 9: Create your business website

After defining your brand and creating your logo the next step is to create a website for your business.

While creating a website is an essential step, some may fear that it’s out of their reach because they don’t have any website-building experience. While this may have been a reasonable fear back in 2015, web technology has seen huge advancements in the past few years that makes the lives of small business owners much simpler.

Here are the main reasons why you shouldn’t delay building your website:

  • All legitimate businesses have websites - full stop. The size or industry of your business does not matter when it comes to getting your business online.
  • Social media accounts like Facebook pages or LinkedIn business profiles are not a replacement for a business website that you own.
  • Website builder tools like the GoDaddy Website Builder have made creating a basic website extremely simple. You don’t need to hire a web developer or designer to create a website that you can be proud of.

Recommended: Get started today using our recommended website builder or check out our review of the Best Website Builders.

Other popular website builders are: WordPress, WIX, Weebly, Squarespace, and Shopify.

STEP 10: Set up your business phone system

Getting a phone set up for your business is one of the best ways to help keep your personal life and business life separate and private. That’s not the only benefit; it also helps you make your business more automated, gives your business legitimacy, and makes it easier for potential customers to find and contact you.

What happens during a typical day at an advertising agency?

An advertising agency owner is responsible for managing their agency, finding clients and producing campaigns for clients. On any given day, a business owner might:

  • Search for leads or follow up with leads on potential new clients
  • Prepare pitches for prospective clients
  • Work on campaigns for clients
  • Present pitches or completed projects to clients in meetings
  • Manage employees

The work of preparing pitches, designing campaigns and meeting with clients is often done with other business partners or employees. Even after an agency grows, however, business owners usually remain involved in these activities.

What are some skills and experiences that will help you build a successful advertising agency?

In order to successfully run an advertising agency, business owners must have knowledge about advertising. It helps to have a degree in marketing or a related field. Business owners who don’t have a four-year degree in the field should at least consider taking some classes and reading publications on the industry. The American Association of Advertising Agencies offers several training programs. has a list of 16 trade publications and high-quality blogs. MarketingProfs, Business Insider and The Knowledge Bank lead the list.

What is the growth potential for an advertising agency?

Advertising agencies can grow to be internationally recognized companies that receive accolades and land clients from all over the world. Advertising Age published the estimated 2014 revenues of the world’s five largest advertising agencies:

  • Omnicom Group (in New York) had an estimated annual revenue of $15.3 billion

What are some insider tips for jump starting an advertising agency?

While it may be tempting to take on any clients who offer work when first starting out, it’s important to remain selective about what clients an agency takes on. Phyllis Dealy, who started her own agency, explains that it’s important to remain true to an agency’s vision by only taking on clients who fit within that vision.

How and when to build a team

An advertising agency should hire a few employees as quickly as possible, but it’s important to resist growing beyond the initial team too quickly. Agencies should first have at least one creative person, someone with a business mind and a person who can manage the daily tasks of making a business run. Dealy stresses the importance of a behind-the-scenes person who can take care of billing, operations, staff issues and similar tasks so that the creative person can focus on planning campaigns. After these people have been hired, Dealy says, additional creative people should be slowly brought on as needed.
