SaaS application development services

Businesses choose software-as-a-service (SaaS) because it runs in any web browser, fits any target audience, and cuts infrastructure overhead. Overcode builds SaaS applications with modern architecture and a proven tech stack.
With just a web browser and internet connection, users can access tools, dashboards, or services that used to require expensive traditional software and installations.
A single SaaS product can serve many businesses using multi-tenant architecture, giving every team value they need without tricky and costly custom setups or local installs.
The SaaS model is predictable, cost-effective, and easy to maintain, ideal when building a long-term business or expanding your cloud-based software offering.

FREQUENTLY ASKED QUESTIONS
Answers to the most common questions about SaaS product development process, cooperation models, and what it’s like to work with Overcode.
Can you help modernize an existing SaaS application?
Yes, we modernize existing SaaS applications, from codebase audits to updating the architecture and refreshing the whole UX/UI. We can help you to:
- Design and develop new features for your existing software following our process.
- Provide you with our specialist(s) who will extend your team and work like your remote employees.
As a result, you would be sure that your SaaS product stays relevant and competitive, without compromising on performance and code quality.
Do you develop SaaS MVPs (Minimum Viable Products)?
Yes, we specialize in SaaS MVP development. This is an ideal way to quickly test an idea, get feedback from users, and enter the market with minimal investment. What we do:
- Conduct the competitor research and define the UX, from user flow to wireframes;
- Design a responsive interface and the UI kit;
- Select the optimal stack for MVP development and further scaling;
- Develop the key features necessary for product launch;
- Set up third-party services for tracking analytics and collecting feedback.
The client receives a working product, ready for the first users. And a clear understanding of where to go next.
If necessary, we develop a prototype or MVP before creating the full version of the product. This is the best approach to minimize risks when launching the full solution. Within the discovery phase, Overcode, together with the client, can distribute tasks across several phases of product release, depending on timeframes and priorities.
Can you integrate third-party tools and APIs into my SaaS product?
Yes, we regularly integrate third-party services and the APIs into the SAAS products of our customers. We can integrate anything — from payment systems (like Stripe) and CRM, to cloud storage providers, AI LLMs, and data visualization tools. We will ensure the safe and stable operation of all APIs and test integration after the setup.
How do you address scalability issues as my business expands? Can you provide ongoing enhancements and feature development? What's your post-launch policy?
For each product, we create a unique design and think about its scalability in advance. This is evident in our overall approach, from the most thoughtful arrangement of elements to a frontend and backend architecture that can withstand a heavy load. Optionally, we can cover your project with automated tests using best practices across load testing.
We will stay in touch with you after the product launch. We can implement the new features and help you fix or improve something. In the post-release period, we provide technical support, eliminate errors, monitor performance, and help to scale your project.
Can you help with market research or identifying the target audience for my SaaS product?
Yes, we can assist you with it during the Discovery phase. We may help you analyze your market: competitors, trends, and target audience. This would help to prioritize features correctly and to ensure that your requirements align with the timeline and budget.
How do you ensure secure payment processing for SaaS subscriptions?
We pay close attention to the security of the products we develop, which is why we have been certified by Stripe, the most popular solution at the moment, and meet the standards of PCI DSS.
We can create simple one-time payment forms and complex subscriptions with flexible payment plans, as well as configure per-seat and metered usage options.
What strategies are used to optimize the software for speed and performance?
When developing and testing each project, we pay attention to application loading speed and performance. We use advanced development tools, apply best practices, and improve processes. Also, as part of quality assurance, we check the product for compliance with benchmarks and generally accepted standards.
How do you ensure the SaaS platform is intuitive and user-friendly? Is mobile responsiveness or a dedicated mobile app included in the scope?
In the Overcode, we can help create a simple and convenient user interface and user experience design. We can also create prototypes to allow you to test the product during the early stages and gather feedback before development. Optionally, we can adapt your app interface for different screens (mobile and tablets) to make the product responsive. In addition to web apps, we can separately develop native mobile apps for iOS and Android, reusing code wherever possible.
What factors influence the cost and timeline of development?
The cost and terms of development depend on:
- The scope of work;
- Complexity of the project features;
- Selected technology stack;
- Interface design;
- Integration with external services.
Can the SaaS solution incorporate AI, machine learning, or predictive analytics? Can the platform integrate with IoT devices or blockchain technology? How do you ensure the software is future-proof for technological advancements?
Sure, we have experience both integrating SaaS products with LLM, for example Chat GPT, and integrating with a custom AI algorithm. We also have experience integrating with IoT devices and blockchain technologies. At the same time, we are not afraid of new challenges. In each project, we aim to create a system taking into account future technological changes, ensuring flexibility and the possibility of adaptation to new solutions.
