How we build it
Design, build, integrate and run software made for the way your organization works: enterprise, web, mobile and AI applications, delivered by a team that stays after launch.
Also known as custom application development, bespoke software development
Custom software development is the design, build, deployment and maintenance of applications made for one organization's users, processes and goals, rather than bought off the shelf. TechTiera provides end-to-end custom software and application development: consulting and discovery, MVP and SaaS product development, enterprise, web, mobile and AI applications, customer and partner portals, cloud-native development and migration, API development and integration, dedicated development teams, and maintenance and support. Delivery combines Agile and Design Thinking, with onshore leadership and global delivery centers.

| Layer | Technologies |
|---|---|
| Front end | React, Next.js, Angular, Vue.js, TypeScript |
| Back end | .NET and C#, Java and Spring Boot, Node.js, Python, Go |
| Mobile | Swift, Kotlin, Flutter, React Native, .NET MAUI |
| Cloud | Microsoft Azure, AWS, Google Cloud, private cloud |

| Quality and security | Playwright, Selenium, JMeter, SonarQube, Snyk, OWASP ZAP |
TechTiera delivers all of these, so the advice follows your needs. A starting point:
| If you have | Consider | Why |
|---|---|---|
| A process that is standard across your industry | Buy a SaaS package or configure a platform | Faster and cheaper when nothing about the process sets you apart |
| Internal forms and workflows that change often | Low-code (Mendix, Power Platform, Appian) | Business users can change it; lower build cost |
| A process that is how you win, or no package fits | Custom application | Fits exactly; you own it and can change it freely |
| Software you plan to sell | Custom SaaS product | You own the IP and the roadmap |
| A package that covers most needs | Package plus custom extensions | Keep custom code outside the package for clean upgrades |
| Not sure yet | Discovery and build-vs-buy assessment | Two to six weeks to a decision with costs |
Scope, integrations, compliance and team size drive cost. Typical ranges for planning:
| Project type | Typical timeline | Indicative budget |
|---|---|---|
| Discovery and prototype | 2 to 6 weeks | US$15,000 to US$60,000 |
| Minimum viable product (MVP) | 8 to 16 weeks | US$60,000 to US$200,000 |
| Business web or mobile application | 3 to 6 months | US$100,000 to US$350,000 |
| Enterprise platform with integrations | 6 to 18 months, phased | US$300,000 and above |
| Maintenance and support | Ongoing | About 15% to 25% of build cost per year |
Ranges are indicative only. TechTiera provides a project-specific estimate after a short discovery.
| Area | TechTiera | Typical vendor |
|---|---|---|
| Starting point | Discovery and build-vs-buy-vs-low-code advice | Assumes custom code is the answer |
| Code ownership | Code, pipelines and documentation in your repository from sprint one | Handed over at the end, if asked |
| Quality | Automated tests, security scans and accessibility checks in every release | Manual testing near launch |
| AI | AI-assisted engineering with human review, and AI features with evaluation sets | AI mentioned, not governed |
| Enterprise context | In-house SAP, Microsoft, CRM, integration and content practices | Application only |
| After launch | SLA-based support, 24x7 where needed, global service desks | Project ends at go-live |
Architects and consultants with large-program experience frame the problem before developers write code.

Defined scope, deliverables and milestones, usually after a discovery phase.
Flexible capacity for evolving requirements, MVPs and proofs of concept.
A named, cross-functional team working as an extension of yours.
Individual developers, architects and testers added to your team.
SLA-based maintenance, support and enhancements on monthly or annual terms.
Custom software development is the process of designing, building, deploying and maintaining software for a specific organization, group of users or function, instead of using off-the-shelf products.
It fits your processes exactly, automates work packages cannot, integrates with your systems, can give a competitive advantage, avoids per-user licence fees for some audiences, and can be sold as a product. You also control the roadmap.
Cost depends on scope, integrations, compliance and team size. As a guide, discovery often costs US$15,000 to US$60,000, an MVP US$60,000 to US$200,000, and enterprise platforms US$300,000 and above. TechTiera gives a range after a short discovery.
Discovery takes 2 to 6 weeks, an MVP 8 to 16 weeks, a business web or mobile app 3 to 6 months, and enterprise platforms 6 to 18 months delivered in phases.
Buy when the process is standard and gives no advantage. Use low-code for internal workflows that change often. Build custom when the process is how you win, no package fits, or you plan to sell the software.
With TechTiera, code, infrastructure scripts and documentation are kept in a repository you control from the first sprint, and ownership is set out in the contract.
