Checklist for Starting a Private Investigation Business

Starting your own private investigation business can be a fulfilling and lucrative experience, but it’s important to make sure you’re fully prepared for the challenges ahead. By following this checklist, you can get your business off to a strong start

Step 1: Write your Business Plan

After coming up with the idea, the next step in starting your private investigation business should be to write a business plan.  The business plan will make you focus on some important aspects of the business, such as who your customers are, how you plan to reach them, projecting sales and expenses, your value proposition to use for marketing, and more. You’ll also need to do some research to calculate exactly what your startup expenses will be and what your ongoing expenses will be.

Not only will a bank require you to have a business plan if you need financing, but multiple studies have shown that having a good business plan increases the odds of starting a successful business. Writing the plan helps you to think through all the aspects of the business and then serves as a guide as you begin.

Step 2: Name the Business

Finding the perfect private investigation business name can be challenging. Not only does the name have to reflect what you do and be appealing to customers, but it also has to be available to use. You can check your state’s website to see if the name is available and register your name.  Your name should make you stand out, reflect your brand, and tell potential customers exactly what you do.

Step 3: Form a Business Structure

A business entity refers to how a business is legally organized to operate. There are four primary business entities to choose from, which include the sole proprietorship, partnership, corporation, and Limited Liability Company (LLC). Each type of entity has its own pros and cons, such as liability exposure, costs, and administrative requirements.

When deciding on which business entity is best for a private detective agency, it normally comes down to the sole proprietorship and Limited Liability Company.

A partnership opens the owners up to unnecessary personal liability because if a partner does something to get the business sued, or runs off with cash from the business, the other partners are personally liable to repay. The corporation can be a good choice because it separates the business assets from the owner’s assets. If the corporation is sued or certain business debts can’t be paid back, the owners aren’t personally responsible to repay them. The downside to the corporation is that it is more complicated than all the other entities and requires more administration than the LLC. If you plan on raising a lot of investment though, the corporation is usually the better choice.

That leaves the sole proprietorship and LLC.

The sole proprietorship is the least expensive and easiest entity to start which is appealing. The downside is the owner is personally liable should anything happen to the business, which is an important consideration. The LLC offers the ability to operate as a sole proprietorship with the liability protection of a corporation. Depending on the state, the cost to form an LLC runs from $40 – $500, which is pretty inexpensive for protecting the owners from business-related lawsuits and certain debts.

Step 5: Apply for Business Licenses and Permits

In addition, there will be general registrations for a PI agency such as a local business license, sales tax permit, and an Employer Identification Number.
