Five Side Hustle Businesses Requiring Minimal Startup Costs
An increasing number of Americans are seeking supplementary income through side businesses. Certain service-based ventures can be launched with almost no initial capital, leveraging existing skills and resources.
A growing number of Americans are turning to side businesses to supplement their income. According to a 2026 QuickBooks survey, 47 percent of adults earned money from a side hustle in the past year, with 33 percent planning to launch a new venture in the next 12 months. Many of these side businesses are service- or online-based, requiring minimal initial investment beyond time and existing resources like internet access and transportation.
Recruiting services represent one such low-startup-cost side hustle. An individual with an extensive network can generate revenue by connecting companies with suitable candidates or assisting job seekers in finding new career opportunities. Startups, in particular, often lack the budget for a full-time recruiter and may welcome consulting services. Commissions can range up to 20 percent of a candidate's first-year salary, and prior networking efforts can provide a significant advantage.
Pet services offer another potential avenue for side income, with Americans spending $158 billion on their pets last year. Offerings such as pet sitting, dog walking, and even pet wellness services, including supplements or specialty foods, can be initiated with low overhead. Demand for pet care services, like pet sitting, has seen a significant rise in several states. While a mobile grooming service might require some initial investment, costs can be mitigated by combining it with other services like pet sitting.
These service-based ideas facilitate growth from a side hustle into a full-time business by capitalizing on existing skills and networks.
