Unless the business has an internal software development team, it will likely need to hire a software development company. These companies have strong teams with broad product development experience.

The development company will ask many questions about the project to understand the scope and provide the most accurate estimate possible. Make sure to understand what the estimate includes—the services provided, design capabilities, launch and maintenance support, and so forth.

Plan for Several Iterations

Iterative development is a standard software development methodology that accelerates the process of creating a product while reducing costs and improving quality.

Software is rarely ready for release after only one iteration. Plan to go through several iterations of the product to get a product that will wow your customers.

From a budgeting perspective, this can extend the project timeline and increase the labor associated with development. Anticipate additional expenses or costs.

Budget for Maintenance Fees

Once the product is released, developers must update and maintain its performance. Many development companies offer a monthly or annual maintenance service, or an internal team can take on the task. Either way, these fees need to be factored into the development budget.

Exploring Different Deployment Strategies for Custom Software Development

Several deployment strategies are commonly used in developing custom software to release and distribute the application. The choice of deployment strategy depends on factors such as the nature of the software, the target platform, the deployment environment, and the development team’s goals and requirements.

Here are some of the most common deployment strategies:

Continuous Deployment

In continuous deployment, software changes are automatically deployed to production environments as soon as they pass automated tests and quality checks. This strategy aims to minimize lead time and accelerate the release cycle by automating the entire deployment process.

Continuous Integration/Continuous Delivery (CI/CD)

CI/CD is a practice that combines continuous integration and continuous deployment. It involves regularly integrating code changes into a shared repository, running automated tests, and automatically deploying the application to production if all tests pass. CI/CD helps ensure that changes are quickly incorporated, tested, and deployed, reducing the risk of integration issues.

Recreate Deployment

This deployment strategy involves shutting down the old version of the application, deploying the new version, and rebooting the entire system. It can frustrate users because they can’t use the system between shutting down the old software and launching the new one.

Blue-Green Deployment

In a blue-green deployment, two identical production environments, referred to as blue and green, are set up. The current version of the software runs in one environment (blue), while the new version is deployed in the other environment (green). Once the green environment is verified and tested, the switch is made, directing traffic to the green environment. This approach allows for zero-downtime deployments and easy rollback in case of issues.

Canary Release

Canary release is a strategy that involves deploying a new version of the software to a subset of users or servers, while the majority of the users continue to use the stable version. This allows for testing the new version in a controlled environment and collecting feedback before rolling it out to all users. It helps mitigate risks and ensures a smoother transition.

A/B Testing

A/B testing, also known as split testing, involves deploying multiple versions or variations of a software application to different user groups simultaneously. Each group experiences a different version, and their interactions and feedback are compared to determine which version performs better. This strategy is commonly used for user interface (UI) and user experience (UX) optimization.

Rolling Deployment

Rolling deployment is a strategy where software updates are gradually rolled out across different servers or clusters, one at a time, while the application remains operational. It allows for a controlled and phased deployment process, reducing the impact of potential issues and facilitating easier rollback if necessary.

Manual Deployment

Manual deployment involves deploying software changes or updates manually to production environments. This strategy provides more control over the deployment process but can be time-consuming and error-prone. It is typically used for smaller applications or in cases where the deployment frequency is low.

Immutable Infrastructure

This approach treats the infrastructure, including servers and environments, as immutable and unable to be modified once deployed. Instead of updating the existing infrastructure, new instances are created with the updated software version and the old instances are replaced. This approach helps ensure consistency, repeatability, and easier rollbacks.

The choice of deployment strategy should consider factors such as the size and complexity of the application, the development team’s agility, the need for scalability, the desired release frequency, and the tolerance for downtime or disruptions.

Exploring the Different Pricing Models in Custom Software Applications

The cost of developing custom software depends on many variables, such as:

  • Software complexity
  • Type of software
  • Compliance requirements
  • Who builds the software

We previously did a deep dive into custom software design and development costs, but here’s a quick reminder.


Development costs rise according to how complex your custom software needs to be. Every feature increases your app’s complexity, driving up development time and, along with it, the cost of your software.

Before talking to custom software developers, make a prioritized list of every feature you want in your software. Then, divide that list into “must have” and “nice to have” features.

Type of Software

The type of software you want to have built may also influence the price. Artificial intelligence and machine learning solutions require high-demand skillsets.

Likewise, it may double your costs if you want a solution with both web and mobile applications. Mobile development means building Android and iOS apps or a hybrid solution that works on both. Again, these require specific skill sets.

Regulatory Compliance

Some industries must adhere to regulations governing data use, security, quality, and other concerns. For example, software created for use in healthcare settings in the United States must be HIPAA-compliant.

The more compliance measures your software needs, the greater the development effort and the higher the cost. Every added layer of security will also add to the price tag.

Development Team

The team that builds your custom healthcare software can also affect the cost.

The most expensive option is hiring an in-house development team. Unless you anticipate ongoing development (customizing it for each client, for example), hiring everyone you need for software development usually isn’t cost-effective.

A freelance developer may be cheaper, but you might be sacrificing quality if they don’t have all the expertise needed. You also aren’t likely to get much support once the software is complete; freelancers live project to project and can’t afford to perform maintenance or act as a help desk.

A custom software development company can often be cheaper than an in-house team, yet have all the expertise at hand. These companies also provide support and maintenance after release.

Understanding the Different Types of Custom Software Development Contracts

When engaging custom software developers, it’s crucial to define the terms and conditions between the client (often referred to as the “buyer” or “customer”) and the software development service provider (often referred to as the “vendor” or “supplier”). These terms are codified in a contract outlining the responsibilities, deliverables, timelines, payment terms, and other relevant aspects of the software development project.

Contracts can take a few different forms. This section provides an overview of some different types of custom software development contracts.

Fixed-Price Contract

In a fixed-price contract, the client and the service provider agree upon a fixed price for the entire project. The contract specifies the scope of work, deliverables, timelines, and payment schedule. This type of contract provides cost predictability for the client, but it may require a well-defined project scope and requirements to avoid disputes or changes in scope.

Time and Materials Contract

In a time and materials contract, the client pays the service provider based on the actual time and resources spent on the project. The contract specifies an hourly or daily rate for the services, and the client is billed accordingly. This type of contract offers flexibility regarding project scope and allows for changes and iterations during development.

Dedicated Team Contract

A dedicated team contract establishes an ongoing relationship between the client and the service provider. The client pays a regular fee to retain the vendor’s services for a specified period. This type of contract is suitable for clients who require ongoing software development support or maintenance services.
