Custom software
Determinds delivers custom software development from the schema up, covering custom backends, full-stack platforms, corporate websites, and e-commerce storefronts. Every system includes the integrations, admin tooling, and reporting that keep it valuable to your team for years after launch.
01 Custom backends
Custom backends shaped around how your business works
Determinds designs and builds custom backends for operations with their own requirements, with every database structure, API endpoint, and business rule drawn from how your business works.
CRM systems
Customer platforms built around your sales process and team workflows, from lead scoring logic to automated follow-up and reporting dashboards.
Content management
Content systems with authoring workflows and granular permissions that scale from a small team to an enterprise, paired with a front end built by the same team.
E-commerce platforms
Commerce backends built for your products, pricing models, and customer segments, covering inventory and payment processing through gateways such as Stripe and PayPal.
Finance and accounting
Backends that automate complex calculations, handle multi-currency transactions and tax rules, and produce audit-ready reporting.
HR and operations
Workforce systems covering onboarding, performance tracking, resource allocation, and operational reporting, with role-based access and approval workflows built in.
Operational automation
Automation across the whole stack that takes repetitive steps out of your workflows, with prediction and routing handed to our AI systems team where a model adds value.
AI systems02 Websites and web applications
Custom websites and web applications built for your business
Determinds builds corporate websites, web applications, and storefronts in React, TypeScript, and Next.js, delivering fast load times, clean code, strong accessibility, and a codebase that can be extended for years.
Corporate websites
Sites engineered to your specification from the interface to the backend, and built with Core Web Vitals in mind from the first release.
Web applications
Client portals, internal management systems, and workflow tools that turn a complex process into screens your team can work in all day.
Editable by your team
Every site ships with a content management system, often a headless one, so your editors can change text, images, and pages without a developer, with training and documentation at handover.
Search foundations
Clean URL structures, semantic HTML, and structured data from the first build, written to Google’s helpful content guidelines.
Accessible and mobile-first
Designed for the phone first and then scaled to tablet and desktop, and built to WCAG 2.1 so the site works for visitors using assistive technology.
Connected to your business
Sites connected to the CRM, payment gateways, analytics, and third-party APIs your business already depends on.
Integrations and API development03 How we deliver
From discovery to a system in production
Discovery and architecture
Our team maps your business processes, data flows, and integration requirements before any code is written.
Schema and API contracts
Schema design, relationship mapping, and API contract definitions establish the foundation for the rest of the build.
Iterative development
Two-week sprints with a demo at the end of each, so you see the system take shape and steer it throughout.
Testing
Automated unit, integration, and load tests run against real-world conditions before every release.
Deployment and monitoring
CI/CD pipelines, logging, and alerting are in place from the first launch, so every release is a routine event.
Support and maintenance
The team that built your system stays on to monitor, update, and optimize it under a service-level agreement.
Built to scale and to pass a security review
The architecture absorbs new load, new features, and changing requirements without a rebuild.

05 Frequently asked
Questions about custom software development
What is custom backend development?
Custom backend development is the server-side half of a system, covering the databases, APIs, business logic, and integrations, which Determinds builds around one client’s workflows rather than configuring from a package. You control the features, the data, and how far the system scales.
How does a custom build compare with WordPress or Shopify?
Determinds builds custom backends for businesses whose workflows have grown beyond a packaged platform. WordPress and Shopify serve standard cases well, and a custom backend gives you full control of the business logic, the data architecture, and the integrations as your business grows.
How long does a custom system take?
Determinds typically delivers a first production release 8 weeks after kickoff, with requirements reaching scope sign-off in 5 working days. Our team works in 2-week sprints with a demo at the end of each, so you see progress from the first sprint.
Can our team edit the website after launch?
Yes. Every Determinds site ships with a content management system for text, images, and pages, and the handover includes training and documentation for your editors.
Can a custom backend connect to the systems already in place?
Yes. Determinds builds every backend API-first, connecting it to the CRM, payment gateways, ERP, and third-party platforms you already use, with 2 core banking integrations in production.
How is the system kept secure?
Determinds designs security in from the first schema, covering OWASP guidelines, TLS in transit, OAuth 2.0 and JWT authentication, role-based access, input validation, and regular dependency audits.
What happens after launch?
Determinds supports every system after launch under a service-level agreement, with the same team that built it. Priority-one incidents carry a 2-hour contracted resolution, with a 1.25-hour median in practice, alongside monitoring, patching, and feature updates.
How much does a custom build cost?
Determinds sets pricing by scope, complexity, and timeline in a written proposal, prepared once requirements reach scope sign-off in 5 working days. The proposal names the milestones, the team, and the service level that applies after launch.
