Custom Software Development

Custom Software Development Built Around How You Operate

We design and build SaaS platforms, ERP and CRM systems, internal tools and APIs that fit your workflows instead of forcing you into someone else's. You own the code, the infrastructure and the roadmap.

What We Deliver

Custom Software Development Capabilities

SaaS Product Development

Multi-tenant SaaS platforms built with tenant isolation, subscription billing and role-based access from the first release. We plan for scale without over-engineering the MVP.

  • Multi-tenant architecture
  • Subscription billing and metering
  • Role-based access control
  • Admin and analytics dashboards

ERP, CRM and Operations Systems

Custom ERP and CRM software that models your real processes, from quoting and inventory to fulfillment and invoicing. We integrate with the accounting, payment and logistics tools you already use.

  • Workflow and approval engines
  • Inventory and order management
  • Customer and pipeline management
  • Accounting and payment integrations

Internal Tools and Automation

Back-office tools that replace spreadsheets, email chains and manual data entry. Small, focused applications that save your team hours every week.

  • Operations and reporting portals
  • Data import and reconciliation
  • Scheduled jobs and notifications

APIs, Integrations and Microservices

REST and GraphQL APIs, event-driven services and third-party integrations with clear contracts, versioning and documentation. We split services only where the domain and team structure justify it.

  • REST and GraphQL API design
  • Event-driven and queue-based services
  • Third-party and partner integrations
  • OpenAPI documentation

Legacy Application Rebuilds

Incremental rewrites of aging applications using the strangler pattern, so the business keeps running while old modules are retired. Data migration is planned, rehearsed and verified.

  • Codebase and data assessment
  • Incremental module replacement
  • Data migration and validation
  • Parallel-run cutover plans

Application Development Consulting

Architecture, build-vs-buy and technology selection advice before you commit budget. Useful when you need a second opinion or a scoped plan your own team can execute.

  • Build vs. buy analysis
  • Architecture and stack selection
  • Scoping and delivery planning

Who custom software development is for

Off-the-shelf software works until your business stops fitting it. Teams start exporting data to spreadsheets, stitching tools together with brittle automations, and paying for seats in three products to cover one workflow. That is usually the point where custom software development pays for itself.

We work with companies that are:

  • Launching a SaaS product and need a reliable multi-tenant foundation, not a prototype that has to be rewritten after the first customers arrive.
  • Running operations on disconnected tools and need a custom ERP, CRM or internal portal that reflects how the business actually works.
  • Maintaining a legacy application that is hard to change, hard to hire for, or running on unsupported frameworks.
  • Exposing data to partners or customers and need well-designed APIs with clear contracts and documentation.

Our approach to application development

Start with the workflow, not the feature list

Before writing code, we sit with the people who will use the system. We map the current workflow, identify where time and data are lost, and turn that into a prioritized backlog. This keeps the first release small and useful instead of large and late.

Engineering practices we apply on every project

  • Version control and code review. Every change goes through a pull request with at least one reviewer. Your team can see every commit.
  • Automated testing. Unit tests for business logic, integration tests for APIs and database access, and end-to-end tests for critical user journeys, all running in CI.
  • Continuous integration and delivery. Pipelines build, test and deploy to staging on every merge, so demos use real, deployed software. Our DevOps consulting team sets this up alongside the application.
  • Infrastructure as code. Environments are defined in Terraform or similar tooling, so staging and production stay consistent and reproducible.
  • Security by default. Dependency scanning, secrets management, least-privilege access and input validation are part of the baseline, not an add-on.
  • Documentation that lives with the code. Architecture decision records, API specs and runbooks are kept in the repository and updated as the system changes.

Architecture that fits the problem

We default to a well-structured modular application and introduce microservices only when there is a clear reason, such as independent scaling needs or separate teams owning separate domains. Fewer moving parts means lower hosting costs and simpler operations. When the product needs a customer-facing front end or mobile app, we coordinate with our web and mobile app development practice so the API and client are designed together.

Engagement models

Fixed-scope project

Best for well-defined builds such as an MVP, an integration, or a specific module. We agree on scope, milestones and price after discovery, and manage changes through a transparent change-request process.

Dedicated team

A stable team of engineers, a tech lead and QA working as an extension of your company. Suited to ongoing product development where priorities shift and the backlog evolves month to month.

Advisory retainer

Senior architects available for design reviews, technology decisions and hiring support while your own team does the building. This pairs well with our IT consulting services.

What influences cost and timeline

Every estimate we give is tied to specific drivers, so you can make trade-offs deliberately:

  • Scope and complexity of business rules, user roles and workflows.
  • Integrations with payment providers, ERPs, identity providers and partner APIs, especially poorly documented ones.
  • Data migration from legacy systems, including cleanup and validation.
  • Compliance requirements such as audit logging, data residency or access controls.
  • Performance and availability targets that affect architecture and infrastructure.
  • Speed. A tighter deadline usually means a larger team, which raises coordination cost.

We phase delivery so the most valuable functionality ships first, and we flag scope that adds cost without adding much value.

Why EvoxSoft

  • You own everything. Code, documentation and cloud accounts belong to you from the first commit.
  • Full-lifecycle capability. Product design, engineering, DevOps and cloud under one roof means fewer handoffs.
  • Visible progress. Working software demoed every sprint, with direct access to the engineers building it.
  • Built to be maintained. Clean code, tests and documentation so your team, or any future team, can extend the system with confidence.

If you are weighing a build, a rebuild or a build-vs-buy decision, tell us about your project and we will help you scope it.

How We Work

Our Engagement Roadmap

Clear stages, clear deliverables, and no black-box handoffs.

01

Discovery and Scoping

We map your workflows, users, integrations and constraints, then agree on what the first release must do and what can wait.

Deliverable: scoped backlog, architecture outline and estimate
02

Architecture and Design

We define the data model, service boundaries, security model and UI flows, and validate the riskiest assumptions with small spikes.

Deliverable: technical design, clickable prototype and delivery plan
03

Iterative Build

Two-week sprints with working software demoed at every review, automated tests in CI and deployments to a staging environment you can use.

Deliverable: tested increments deployed to staging each sprint
04

Launch and Handover

Production rollout with monitoring, runbooks and documentation, followed by a support period or an ongoing maintenance agreement.

Deliverable: production release, runbooks and full repository handover

FAQ

Frequently Asked Questions

Which programming languages and frameworks do you work with?

We are stack-agnostic and choose what fits your product, team and hosting. Our engineers work across TypeScript and Node.js, PHP and Laravel, Python (Django and FastAPI), Go and Rust, with React, Next.js, Vue or Angular on the front end and PostgreSQL, MySQL and Redis for data, deployed on AWS, Microsoft Azure or Google Cloud with GitHub Actions or GitLab CI/CD pipelines. If you already have a codebase, we extend it in the stack you use rather than rewriting it.

How much does custom software development cost?

Cost depends mainly on scope, the number and complexity of integrations, data migration needs, security and compliance requirements, and how quickly you need to launch. We give you an itemized estimate after a discovery phase, so you can see which features drive the budget and decide what to defer.

How long does it take to build a custom application?

A focused MVP typically takes a few months, while larger platforms with many integrations are delivered in phases over a longer period. We break the work into releases so you get usable software early rather than waiting for one big launch.

Who owns the source code and intellectual property?

You do. Our agreements assign the code, designs and documentation we create for you to your company, and we work in repositories and cloud accounts you control. There is no licensing lock-in.

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

Buy when an existing product covers your process well and the workflow is not a competitive differentiator. Build when your process is unique, when integration costs across several tools become painful, or when per-seat licensing no longer makes sense. We will tell you honestly if an off-the-shelf tool is the better choice.

What engagement models do you offer?

We offer fixed-scope projects for well-defined builds, dedicated teams for ongoing product development, and advisory retainers for architecture and technical guidance. Many clients start with a fixed-scope discovery or MVP and then move to a dedicated team.

Can you work with our existing development team?

Yes. We regularly work alongside in-house engineers, following your code review, branching and deployment practices, or helping establish them if they are not yet in place. The goal is that your team can own the system comfortably after we step back.
