We're Open For Business!


Welcome to our Warrenton, Missouri!  This checklist is a starting point for you as you begin your business. It is in no way meant to be a substitute for professional advice or counsel.


Formulation and Planning…

Formalize Your Idea

Formally select a business idea, product or service that you will sell. This may sound like an easy step, but think hard about what exactly you will be selling and whether you have the skills and qualifications to run a business. This is also a good time to start thinking about the feasibility of making your business idea profitable.


Research the business industry

  • What will you sell? Who will buy it? How often?

  • Are you willing and able to do what it takes to sell your product?

  • Who are the competitors?

  • What will your product cost to produce, market, sell, and deliver? Can you make a profit? How long will it take for your business to make a profit?

  • What compliance issues do you need to address?


How to Make Your Business Plan Stand Out

One of the first steps to business planning is determining your target market and why they would want to buy from you.  For example, is the market you serve the best one for your product or service? Are the benefits of dealing with your business clear and are they aligned with customer needs? If you're unsure about the answers to any of these questions, take a step back and revisit the foundation of your business plan.  The following tips can help you clarify what your business has to offer, identify the right target market for it and build a niche for yourself.


Be Clear About What You Have to Offer

Ask yourself: Beyond basic products or services, what are you really selling?  Consider this example: Your town probably has several restaurants all selling one fundamental product—food. But each is targeted at a different need or clientele.  One might be a drive-thru fast food restaurant, perhaps another sells pizza in a rustic Italian kitchen, and maybe there’s a fine dining seafood restaurant that specializes in wood-grilled fare. All these restaurants sell meals, but they sell them to targeted clientele looking for the unique qualities each has to offer. What they are really selling is a combination of product, value, ambience and brand experience.


When starting a business, be sure to understand what makes your business unique.

What needs does your product or service fulfill? What benefits and differentiators will help your business stand out from the crowd?

Don’t Become a Jack of All Trades...Learn to Strategize

It’s important to clearly define what you’re selling. You do not want to become a jack-of-all trades and master of none because this can have a negative impact on business growth. As a smaller business, it's often a better strategy to divide your products or services into manageable market niches. Small operations can then offer specialized goods and services that are attractive to a specific group of prospective buyers.

Identify Your Niche

Creating a niche for your business is essential to success. Often, business owners can

identify a niche based on their own market knowledge, but it can also be helpful to conduct a market survey with potential customers to uncover untapped needs. During your research process, identify the following: 

  • Which areas your competitors are already well-established

  • Which areas are being ignored by your competitors

  • Potential opportunities for your business.


Web site considerations

If you are going to have a web site, be sure to register the domain name.

Using a domain registry service, see if the business name is available for use as an Internet domain name.

  • If your business will be a sole proprietorship and you will be using an assumed name, you must check the availability of the name you have chosen and register it.

  • If your business will be a partnership, draw up your partnership agreement. If the partnership will be using an assumed name, register the fictitious name.

  • If your business will be a corporation, file Articles of Incorporation.

Moving Forward…

Choosing a business location

If you are going to have a brick-and-mortar presence, research possible locations for your business. Where appropriate, analyze that location for traffic, parking, customer and delivery access.


Planning and Zoning

A Zoning Code is oriented toward how a project fits into a community:  it regulates setbacks, types of uses, height, parking requirements, design (for some types of projects) and similar concerns. The area is divided into various zones and each zone will have its own set of regulations.  For example, the regulations that would apply in a single family residential district will be different than those for a multi-family or commercial district.  When a separate Zoning Permit is required for a new development, there will generally be a requirement to have that application to accompany site and building plans (including preliminary architecture).  Before purchasing property for your business site, contact your Planning and Zoning department to verify zoning.  Make sure to look at an up to date zoning map and ask the zoning officer to make a determination of which zone the property is in and what relief may be needed.

Public Utilities

To ensure that your business site has the necessary utilities, contact the public works department for the jurisdiction of your site location.

  • Meridian Waste (trash) – 636-566-8367


Building Codes and Permits

Building Code is oriented toward ensuring that structures are constructed to an appropriate standard and are safe for the uses intended.  Application for most Building Permits must be accompanied by detailed construction drawings.


If you plan to build a new building or alter an existing building, a building permit will be required.  Contact the Building Department for Warrenton, Truesdale or Warren County to obtain those requirements and an application.
