As a new company, success largely depends upon the people that you hire to help run it. If you’ve just established a startup, you might not think you can afford a lot of specialists to help you out, but some of them are really essential. These four specialists might be the kind of roles you think you can do without, but that couldn’t be further from the truth.

1. IT Specialist

It’s almost necessary to have someone who manages your business tech. You can choose to hire an in-house employee or contract with an IT service—both have distinct advantages and disadvantages.

IT specialists monitor and maintain networks, hardware and software as well as troubleshoot them when there is a problem. A good IT employee can save you a lot of costly downtime. IT people have different specializations and qualifications such as a master’s of information security degree, and they can help prevent data loss, build networks and secure your confidential information.

2. Accountant

An accountant will handle any invoices and monitor your funds, letting you know where the financial side of things stand. They can offer invaluable advice regarding business expenses, revenue and budgeting. Without having a dedicated accountant to manage your finances, you run the very real risk of mismanaging money and running out of it, which could result in the closure of your business.

3. Marketer

Marketers are the heart of most businesses because, obviously, if you aren’t appealing to the right customers and making sales of your products, you won’t remain in business for very long. Digital marketers can help you develop your online presence to better appeal to customers, as well as spearhead or assist with advertising efforts.

Hiring a marketing consultant or marketing agency rather than an in-house employee might be the best option for smaller businesses just starting out.

4. HR Specialist

HR specialists manage one of the most important elements of your business—your employees. As your company grows and your number of employees increases, you will run into problems if there isn’t someone to oversee employee issues.

HR will handle things such as ensuring there are a reasonable set of employee rules to follow, as well as vacation and sick day policies. An HR specialist will also be able to help ensure all hirings and firings are done legally and while adhering to best practices.

If your business has not even looked into hiring these specialists, you should look into it right away. They are all integral to business success, and especially as your business grows from a small startup into something larger, you will need people who can handle different yet important elements of your business. It’s always best to bounce ideas off of other professionals anyway, and they can offer a unique and knowledgeable perspective.
