Custom Software Development Services.

Custom software built around how your business works: internal tools, enterprise platforms and AI-powered apps, from discovery and architecture to support.

Custom software development is designing and building an application for one organisation’s own processes, instead of adapting the business to an off-the-shelf product. EqualPixels builds custom web platforms, internal tools, enterprise systems and AI-powered software for startups and growing companies, and runs several products of our own on the same stack.

Custom software delivery flow: discovery, a fixed scope and quote, architecture, design, two-week build sprints, then launch and ongoing support
How we build custom software

What is custom software development?

Off-the-shelf software is built for the average customer. That works until your process is the thing that sets you apart: the way you price, dispatch, approve or report. Custom software encodes that process directly, connects to the tools you already use, and belongs to you, with no per-seat licence that grows with your team.

It is not always the right call. If a SaaS product does 90 percent of what you need, configuring it is usually cheaper. Custom software earns its cost when the remaining 10 percent is where your margin, compliance or customer experience lives.

What custom software do we build?

  • Internal tools and back-office systems

    Operations dashboards, approval workflows, scheduling, dispatch, inventory and reporting tools that replace the spreadsheets and group chats a growing team outgrows.

  • Enterprise software

    Multi-department platforms with roles and permissions, audit trails, multi-currency finance, single sign-on and integrations with ERP and HR systems.

  • Customer-facing platforms and portals

    Booking systems, client portals, marketplaces and self-service accounts, built as web applications with mobile apps where your users need them.

  • AI-powered software

    Applications with language models built into the workflow: document extraction, proposal and email drafting, semantic search over your own content, and assistants that act inside the app. When the core of the product is an agent, see AI agent development.

  • SaaS products

    If the software will be sold to other companies, it needs multi-tenancy, billing and onboarding from day one. That is our SaaS development service.

  • Rebuilds of legacy systems

    Replacing an ageing desktop app, Access database or unmaintained PHP system with a modern web platform, migrating the data and running both side by side until the new one is trusted.

If your process is standard, buy. If your process is your advantage, build. Many clients do both: an off-the-shelf CRM or accounting package, with custom software around it and an integration layer joining them.

How do we build custom software?

  1. DiscoveryWorkshops with the people who will use the software, a map of the current process, and a list of what must be true on launch day. Strategy first, then code.
  2. Scope and fixed quoteA written scope, screen list, data model and fixed price before work begins, so there are no hourly surprises.
  3. ArchitectureDecisions on tenancy, data, integrations and hosting written down up front. For larger systems this is a software architecture engagement in its own right.
  4. DesignWireframes and a clickable prototype in Figma, tested with real users before development starts. See UI/UX design.
  5. Build in two-week sprintsWorking software to review every week on a staging server, with automated tests and code review on every change.
  6. Launch, then supportProduction deployment with monitoring and backups, a 30-day warranty, and a maintenance retainer if you want one.

Technology we use

Backend
Laravel and Django for business applications, Node.js for real-time and integration-heavy services, Python for data and AI work.
Frontend
React and Next.js with TypeScript, often rendered through Inertia.js so there is no separate API layer to keep in sync.
Mobile
Flutter, React Native and native Swift, chosen per project.
Data
PostgreSQL by default, Redis for queues and caching, pgvector when the app needs semantic search.
AI
The OpenAI and Anthropic APIs, with providers and models configurable per customer and every call logged and metered.
Infrastructure
Docker, GitLab CI pipelines, atomic releases on Ubuntu and Nginx or AWS, with Cloudflare in front.

We build security in from the first sprint and use the OWASP Application Security Verification Standard as the checklist for authentication, access control and data handling.

How much does custom software development cost?

Custom software projects typically start at about $15,000 for a focused internal tool or a first version with one core workflow. Multi-role platforms with integrations, finance and reporting usually run $40,000 to $120,000, delivered in milestones. Every project gets a fixed quote for a defined scope before work begins.

What moves the number: how many user roles and workflows there are, the number of systems to integrate, data migration from the old system, compliance needs, and whether you need mobile apps as well as the web platform. A first release usually ships in 8 to 16 weeks.

What do you own at the end?

Everything: the source code in your repository, the infrastructure in your cloud account, the database, the designs and the documentation. There is no licence fee to EqualPixels and no lock-in. If your own team takes over, we hand over with a walkthrough and a runbook.

Case study

Agenso: one platform to run an agency

Agenso started as the custom internal system we built to run EqualPixels: multi-currency invoicing, project profitability, payroll and a double-entry ledger. It now runs as a SaaS for other agencies.

How much does custom software development cost?

A focused internal tool or a first version with one core workflow typically starts at about $15,000. Multi-role platforms with integrations, finance and reporting usually run $40,000 to $120,000. You get a fixed quote for a defined scope before work begins.

How long does it take to build custom software?

A first release usually ships in 8 to 16 weeks, in two-week sprints with a live demo every week. Larger platforms are released in phases, so your team starts using the most valuable part early.

What is the difference between custom software and off-the-shelf software?

Custom software is built around your workflow and owned by you; off-the-shelf software makes you adapt to the vendor’s template and charges per seat. Buy when your process is standard, build when your process is your advantage.

Can you add AI to custom software?

Yes. We build language-model features into the workflow itself, such as document extraction, drafting, semantic search and in-app assistants, with the model provider configurable and every call logged. Our own product Agenso runs AI workflows on OpenAI, Anthropic and other providers this way.

Do we own the source code?

Yes. Code, data, designs and documentation are yours, in your own repository and cloud account, with no licence fee to EqualPixels.

Can you take over an existing system someone else built?

Yes. We start with a code and architecture review, fix what is risky, and then continue development or plan a phased rebuild if the foundations will not carry the roadmap.

Which industries do you build software for?

Our shipped work covers car rental and transport (Odobase), real estate (VantixCRM and Houzez CRM), agencies and professional services (Agenso), automotive marketplaces (Carsooq) and social media management (Quevix).
