What We Build

Eight Categories of
Custom Software.

From solo-founder MVPs to enterprise platforms — if you can describe it clearly, we can scope it, design it and build it.

🗂️

Custom CRM Development

A CRM built around your exact sales process, pipeline stages and team structure — not the other way around. Custom dashboards, automation rules, contact management, activity logging and integrations with your existing tools. No per-seat licensing. No features you'll never use. You own the code.

📱

Mobile App Development

Cross-platform iOS and Android applications built in React Native — one codebase, native performance on both platforms. Progressive Web Apps (PWAs) for zero app-store friction. From consumer-facing products to internal business tools: UX design, development, testing and App Store deployment all handled.

🛒

Bespoke E-Commerce Platforms

Custom e-commerce development for businesses whose requirements exceed Shopify or WooCommerce — complex product configurations, custom checkout flows, B2B pricing tiers, subscription commerce, multi-vendor marketplaces and bespoke inventory or fulfilment logic. You own the platform and pay no transaction fees.

🌐

Web Application Development

SaaS platforms, client portals, internal dashboards, booking engines, property management systems and any other web-based application your business needs. Built on React, Next.js and Node.js with clean, documented, scalable architecture from day one.

🤖

AI-Powered Applications

Custom integration of OpenAI GPT-4o, Anthropic Claude, Google Gemini and specialist models into business applications — AI chatbots, document processing pipelines, content generation tools, intelligent search, data analysis dashboards and workflow automation. Build competitive advantages that off-the-shelf software cannot replicate.

🔌

API Development & Integration

Custom REST and GraphQL API development. Third-party integrations — payment gateways (Stripe, PayPal), logistics providers, accounting software (Xero, QuickBooks), CRM and ERP systems. We make your existing tools communicate with each other cleanly and reliably.

📦

SaaS MVP Development

Build your software product from validated idea to investable MVP. RC Media provides product strategy, UX design, front-end and back-end development, cloud deployment and post-launch iteration — everything a startup or product team needs without hiring a full in-house engineering team.

🔄

Legacy System Modernisation

Re-platform outdated systems onto modern frameworks, migrate from on-premise to cloud, improve performance, add mobile compatibility and extend the usable life of proven business logic in new, maintainable architecture. Preserve what works; replace what doesn't.

Custom vs Off-the-Shelf

Why Build
Something Bespoke?

Off-the-shelf software is designed for everyone — meaning it fits no one perfectly. Here is what custom development gives you that subscriptions never can.

🎯

Exact Fit

Software built around your exact process, not a generic workflow you have to adapt to. No workarounds. No unused features. No paying for capabilities you will never touch.

💰

No Per-Seat Licensing

Salesforce, HubSpot, SAP — licensing fees compound as you grow. A custom CRM or platform has no per-user cost beyond hosting. You own the IP outright.

🔗

Native Integration

Custom software integrates directly with your existing stack — your accounting tool, your logistics provider, your data warehouse. No brittle middleware, no Zapier chains.

📈

Scales With You

Built for your current needs with architecture that supports your future ones. No forced migrations when you outgrow the tier you're on.

🛡️

You Own It

The code is yours. The database is yours. The IP is yours. You are not dependent on a vendor's pricing decisions, acquisition or deprecation notice.

🤖

AI-Ready by Design

Custom software integrates AI APIs directly into your workflows — automating tasks, generating insights from your own data and building advantages that are impossible in packaged software.

How We Work

From Idea to
Production Software.

A five-stage process giving you confidence at every step — fixed scope, fortnightly builds and no surprises at launch.

📋
Fixed price or time & materialsWe scope every project before quoting. You choose a fixed-price contract or a transparent time-and-materials retainer.
🔍
Full code handover on completionSource code, documentation and deployment guides delivered at project close. The software is entirely yours.
🛡️
90-day post-launch support includedBug fixes and minor adjustments included for 90 days after go-live. No hidden charges for day-one issues.
1

Free Discovery & Scoping

We map your requirements, user flows and technical constraints. You receive a written specification document and detailed quote before a line of code is written — clear scope, clear cost, no surprises.

2

UX Design & Prototyping

Wireframes and interactive prototypes built in Figma. You test and approve the application before development begins — validating flows and eliminating expensive changes mid-build.

3

Agile Development Sprints

Two-week development sprints with working builds at each sprint close. You see real progress every fortnight, review working software and can steer priorities throughout.

4

QA, Testing & Launch

Cross-device and cross-browser testing, code review, security audit and performance baseline before deployment. Staged rollout with rollback capability on all production launches.

5

Support & Iteration

90-day bug-fix warranty post-launch. Ongoing development retainers available for continuous feature work — we grow the product with your business.

Frequently Asked Questions

Custom Development FAQ

Can RC Media build a custom CRM system?
+
Yes. RC Media builds fully custom CRM systems tailored to your exact sales process, pipeline, team structure and reporting requirements. Unlike Salesforce or HubSpot, a bespoke CRM has no per-seat licensing fees, integrates natively with your existing tools and matches your workflow precisely. We build on modern frameworks with clean REST or GraphQL APIs for future integrations. Contact hello@rcmedia.net to discuss your CRM requirements.
Does RC Media develop mobile apps for iOS and Android?
+
Yes. RC Media develops cross-platform mobile apps using React Native for iOS and Android — one codebase, native performance on both platforms. We also build Progressive Web Apps (PWAs) for cases where app store submission is not required. We handle UX design, development, testing, App Store and Google Play submission and 90-day post-launch support.
Can RC Media build a bespoke e-commerce platform?
+
Yes. RC Media builds fully custom e-commerce platforms for businesses whose requirements go beyond Shopify or WooCommerce — complex product configurations, custom checkout flows, B2B pricing tiers, subscription commerce, multi-vendor marketplaces and bespoke inventory or fulfilment systems. Custom e-commerce means no per-transaction fees, no template constraints and complete ownership of the platform.
Can RC Media integrate AI into a custom application?
+
Yes. RC Media integrates AI APIs — OpenAI GPT-4o, Anthropic Claude, Google Gemini and specialist open-source models — into custom applications. Use cases include AI chatbots, document processing pipelines, intelligent search, content generation tools, data analysis dashboards and automated workflow systems. AI integration is available as part of any custom development project.
How long does a custom development project take?
+
Timelines depend on scope. A focused SaaS MVP, custom CRM or mobile app typically takes 8–16 weeks from scoping to launch. A complex multi-feature platform takes 16–28 weeks. RC Media provides a fixed timeline with milestone-based delivery and fortnightly build reviews so you always know exactly where the project stands.
