Custom Software Development for US Businesses

Web applications, internal tools, APIs, and modernized legacy systems, built around how your business actually works, connected to what you already run, and maintained after launch.

Custom Software Development

Software that fits the business, not the other way around

When a process has outgrown spreadsheets, or three tools won't talk to each other, off-the-shelf software usually means more workarounds, not fewer.

Andriosol Technologies is a custom software development company working with businesses across the United States. We design and build web applications, internal tools, and integrations around your real workflow. That means talking to the people who do the work every day before we write any code.

We started out building Android and iOS apps, then moved into the backends, integrations, and business systems behind them. Today we handle the whole arc: discovery, architecture, development, integration, and long-term maintenance.

What you get

  • A written plan and architecture before development starts, so scope is clear.
  • Working software early — regular checkpoints instead of one big reveal.
  • Integration with your stack — CRM, ERP, accounting, payments, e-commerce.
  • You own the code, the documentation, and the accounts.
  • A maintenance handoff on every project, so the system keeps working.
What We Build

Software development services

One team from whiteboard to production, whether you need a new product, a better internal tool, or an old system brought up to date.

Web Application Development

Secure, browser-based applications like customer portals, dashboards, booking systems, and SaaS products that work on any device.

Internal Tools & Business Systems

Replace spreadsheets, email chains, and copy-paste with purpose-built tools for orders, scheduling, inventory, approvals, and reporting.

API & Backend Development

Reliable APIs and backend services that power your apps and let your systems share data safely.

Systems Integration

Connect CRMs, ERPs, payment processors, and e-commerce platforms into one automated workflow, so data is entered once.

Mobile App Development

Android and iOS apps, where we got our start, built together with the backend and systems they depend on.

Legacy Software Modernization

Move aging desktop or on-premise software to modern, maintainable platforms, one step at a time, without disrupting daily operations.

Why Andriosol

We solve the problem, then write the code

Most failed software projects aren't coding failures. They're cases of confidently solving the wrong problem. That's why every engagement starts with discovery: understanding the real workflow, where it breaks down, and what "done" should look like.

From there you get a concrete plan, working software early, and a team that stays on after launch. We'd rather integrate cleanly with the tools you already use than convince you to rip them out.

Need AI in the mix? Our AI development services plug into the same systems we build. Need a public-facing site too? See website development.

Our development process

  • Discover — map the real workflow with the people who use it daily.
  • Design — agree on architecture, scope, and how it fits your existing systems.
  • Build — iterative development with regular demos.
  • Integrate — connect to your existing tools so data flows automatically.
  • Maintain — monitoring, fixes, and new features as the business changes.

FAQ

Software development questions we hear most

How much does custom software development cost?

Cost depends on what the software needs to do, how many systems it connects to, and how many people will use it. We start with a discovery phase and give you a written estimate tied to a clear scope before development begins.

How long does it take to build custom software?

Smaller internal tools can be in use within weeks; larger platforms take longer. We work iteratively, so you see and use working software early instead of waiting for one big launch at the end.

Who owns the code?

You do. The code, documentation, and accounts belong to your business, and we're happy to sign an NDA before any detailed discussion.

Should we buy off-the-shelf software or build custom?

If an existing product fits your process well, buy it, and we'll say so. Custom software makes sense when off-the-shelf tools force painful workarounds, don't talk to each other, or can't handle how your business really operates.

Can you take over or modernize an existing system?

Yes. We regularly review existing codebases, stabilize them, and modernize legacy systems step by step, without a risky all-at-once rewrite.
