Besides knowing the options where to hire a cross-platform developer, teams have to select the right engagement model. Depending on project requirements, budget, and timeline, companies have the opportunity to choose among several engagement models.

Full-time employment

Provided that teams hire a cross-platform developer as a full-time employee, it offers the advantage of having dedicated resources working exclusively on your project. You can advertise the job opening, conduct interviews, and make a direct employment offer. This model provides better control and flexibility over the development process, but it also involves long-term commitments and additional costs like employee benefits and office space.

Freelance developers

Platforms like Upwork, Freelancer, and Toptal can connect you with a pool of cross-platform developers. Freelancers that work on a project basis offer flexibility in terms of project duration and cost, but you need to closely manage their work and ensure their availability throughout the project.

Dedicated Developers vs Freelancers

Dedicated development team

This model allows businesses to hire a dedicated development team or a remote software development company specializing in cross-platform development. This team will work exclusively on your project, following your requirements and timeline. The advantage is having a committed team with the required expertise, infrastructure, and project management capabilities. It is a suitable model for long-term projects or when they require continuous development and maintenance.

Managed service providers

That’s an engagement model with end-to-end solutions for cross-platform development. They handle the entire development process, from planning and design to implementation and maintenance. It’s suitable when companies want to outsource the entire project or specific components to an experienced team. Managed service providers can also offer ongoing support and maintenance services.

Collaborative development

This model involves partnering with another organization or developer that specializes in app development. It allows you to leverage their expertise and resources while sharing the workload and responsibilities. Collaborative development can be done on a project-by-project basis or as a long-term partnership.

How to hire a cross-platform developer: enagagement models

Before finalizing an engagement model, the team has to consider numerous factors, including the complexity of your project, budget constraints, desired level of control, and the specific skills and experience required. It’s also important to thoroughly evaluate the expertise, portfolio, and reputation of the developers or companies they consider for hire.


When companies decide to hire a cross-platform app developer, it commonly involves various cost considerations depending on factors that impact the final cost. Let’s look at some additional details to help teams understand the cost range:

Factors to influence the cost of hiring cross-platform developers

  • The expertise and experience of a cross-platform developer significantly influence their rates. Developers with several years of experience and a proven track record in cross-platform development frameworks like React Native or Flutter will generally command higher rates due to their specialized skills and knowledge.
  • Development rates can vary based on the location of the professional. Rates in countries with a higher cost of living, such as the United States, United Kingdom, or Australia, tend to be higher than those with lower living costs, such as Poland, Ukraine, or Mexico. This difference in rates can be attributed to the local economic factors and market demand for cross-platform developers.
  • The complexity of your project plays a significant role in determining the cost. Projects with complicated features, advanced functionalities, or tight deadlines may require developers with higher skill levels, which can result in higher costs. Additionally, if the project requires integration with complex systems or third-party services, it may require more specialized expertise, impacting the overall cost.
  • The cost of hiring a cross-platform developer can also depend on whether you choose an individual developer or a development agency. Freelancers generally have lower rates compared to agencies, but agencies often provide additional services such as project management, quality assurance, and a team of experts. These added benefits can justify the higher rates charged by service providers.
  • The prevailing market demand for cross-platform developers in your region or industry can impact pricing. In highly competitive markets with a scarcity of skilled professionals, the cost to hire a cross-platform developer may be higher. Conversely, in areas with a larger pool of available developers, rates may be more competitive.
  • The hiring model you opt for can affect the cost structure. The option to hire a cross-platform developer on a full-time basis typically involves a higher cost compared to part-time or project-based contracts. Full-time employment often includes benefits and additional expenses associated with long-term commitments, while part-time or project-based contracts offer more flexibility but may have higher hourly rates.

In terms of hourly rates, they can vary significantly based on the factors mentioned above. On average, you can expect rates to range from $30 to $150 or more for cross-platform developers. These are only approximate rates and can vary considerably depending on the aforementioned factors and market conditions.
