Any of these factors may impact our business unfavorably. Even after the COVID-19 pandemic has subsided, we may continue to experience adverse impacts to our business as a result of its global economic impact, including any recession, economic downturn, or increased unemployment that has occurred or may occur in the future.
Failure to manage our growth effectively could increase our expenses, decrease our revenue, and prevent us from implementing our business strategy and sustaining our revenue growth rates.
We have been rapidly growing our revenue and number of clients, and we will seek to do the same for the foreseeable future. However, the growth in our number of clients puts significant strain on our business, requires significant capital expenditures and increases our operating expenses. To manage this growth effectively, we must attract, train, and retain a significant number of qualified sales, implementation, client service, software development, information technology and management personnel. We also must maintain and enhance our technology infrastructure and our financial and accounting systems and controls. If we fail to effectively manage our growth or we over-invest or under-invest in our business, our business and results of operations could suffer from the resultant weaknesses in our infrastructure, systems or controls. We could also suffer operational mistakes, a loss of business opportunities and employee losses. If our management is unable to effectively manage our growth, our expenses might increase more than expected, our revenue could decline or might grow more slowly than expected, and we might be unable to implement our business strategy. In addition, our revenue growth rates may decline in future periods as a result of various factors, including our failure to manage our growth effectively, our increased market penetration and the maturation of our business, slowing demand for our services, reductions in the number of employees by our clients, reductions in the number of our clients, public health issues such as the COVID-19 pandemic and a decrease in the growth of the overall market, among other factors.
The markets in which we participate are highly competitive, and if we do not compete effectively, our operating results could be adversely affected.
The market for payroll and HCM solutions is fragmented, highly competitive and rapidly changing. Our competitors vary for each of our solutions and primarily include payroll and HR service and software providers, such as Automatic Data Processing, Inc., Paychex, Inc., Paycom Software, Inc., Paycor, Inc., Ultimate Software Group, Inc. and other local and regional providers.
Several of our competitors are larger, have greater name recognition, longer operating histories and significantly greater resources than we do. Many of these competitors are able to devote greater resources to the development, promotion and sale of their products and services. Furthermore, our current or potential competitors may be acquired by third parties with greater available resources and the ability to initiate or withstand substantial price competition, which may include price concessions, delayed payment terms, or other terms and conditions that are more enticing to potential clients. As a result, our competitors may be able to develop products and services better received by our markets or may be able to respond more quickly and effectively than we can to new or changing opportunities, technologies, regulations or client requirements.
In addition, current and potential competitors have established, and might in the future establish, partner or form other cooperative relationships with vendors of complementary products, technologies or services to enable them to offer new products and services, to compete more effectively or to increase the availability of their products in the marketplace. New competitors or relationships might emerge that have greater market share, a larger client base, more widely adopted proprietary technologies, greater marketing expertise, greater financial resources, and larger sales forces than we have, which could put us at a competitive disadvantage. In light of these advantages, current or potential clients might accept competitive offerings in lieu of purchasing our offerings. We expect intense competition to continue for these reasons, and such competition could negatively impact our sales, profitability or market share.
If we do not continue to innovate and deliver high-quality, technologically advanced products and services, we will not remain competitive and our revenue and operating results could suffer.
The market for our solutions is characterized by rapid technological advancements, changes in client requirements, frequent new product introductions and enhancements and changing industry standards. The life cycles of
