The cost of outsourced software development for startups varies widely depending on factors like product complexity, business needs, design requirements, team size, and timeline. In most cases, custom software development companies’ budgets range from $25,000 to $100,000+, depending on scope and technical needs.
That said, modern tools, cloud services, and remote dedicated development teams make it possible to start with a much lower upfront investment by focusing on an MVP and building only what’s essential. At Fively, we always provide a clear cost estimate and development roadmap before work begins, helping startups plan realistically and invest every dollar wisely.
A custom software development firm is engaged in building software from scratch in accordance with the needs of the customer and carrying out further technical support for it. In particular, such a software company (whether in-house development or outsourced) provides consulting services, designs software architecture, drafts technical documentation, implements and tests software, and provides technical support.
Fively provides services for upcycling software projects and overhauling the UI and UX design of applications. We have ample experience in performing code reviews and audits, app debugging, and software re-architecting.
Our specialists can jump into the game, even when the chances of an early release are utterly slim, in order to put things right and get your product up and running.
Obviously, custom software engineering has a number of advantages. Here are some of them:
Tailor-made. Businesses can get truly customized software, every element of which works like clockwork, instead of strenuously picking a suitable off-the-shelf package or using multiple apps at once to get all the functionality they need.
Cost-effective. Despite the fact that there is a bunch of free software for business, and the cost of some off-the-shelf solutions seems fairly low, it can still cost a pretty penny to make the entire system function properly, since you will most likely need to pay for several solutions, buy some functions separately, or spend money on premium subscriptions, for the sake of a couple of necessary features. In the long run, a custom application is definitely a more profitable investment.
Upgrade-friendly. Another reason to seriously consider developing a custom solution is full control over the product, which, if necessary, allows you to easily extend its functionality or rework some previously-integrated features. At Fively, we take a conscious approach to software development and create future-proof custom applications that are easy to maintain and upgrade.
Wide Functionality. Relying on the services of a company, you can count on getting all the desired features integrated without exception. Forget about using multiple solutions from different vendors, premium subscriptions, and buying over-priced plugins. All you really need is one custom application, because, with a custom solution, you always have options to choose from.
Flawless Support. It's no surprise that custom app support is much better than that in the apps that can be found on the general market. You not only know every little detail in the application, but you also always have someone to turn to for help. You don't have to wait weeks for a response from help desks of popular solutions if you’ve decided to purchase a bespoke application for business.
Uncompromising Security. While cybersecurity is a pressing issue nowadays, tailored apps provide the very unbreachable protection that allows you to keep your data fully secured. Run your business under the aegis of cutting-edge technologies and rest assured that it is too tough for cybercriminals!
Many specialists work on the creation of custom software products, namely:
Project managers organize the work on the project and maintain communication between the customer and the contractor. IT project managers find out the needs of clients, help to form a vision of the final product, and give reports on the job done.
UI/UX Designers create user-friendly interfaces for custom software solutions. Their task is to make products not only functional and handy, but also aesthetically appealing.
Front-end developers are engaged in the development of the client-side of a web application, recreating a functioning layout prepared by a designer with the use of programming languages and frameworks.
Back-end developers create the core of the product, which is located on the server and is hidden from the eyes of users. These backend specialists create web application logic and set up database management systems.
At Fively, there are front-end, back-end, and full-stack developers - multi-skilled experts with a strong background in both branches of web development.
Testers and QA engineers work hand in hand to prevent a product from defects. They are also responsible for identifying and fixing existing bugs in an application in order to provide the end-user with a flawless experience.
