TMS Outsource plans, builds, and launches custom web applications for companies that need production-grade software, not templates. From early-stage SaaS MVPs to complex multi-tenant enterprise platforms, our engineering teams handle the full stack: product discovery, UI/UX design, backend architecture, frontend development, QA, infrastructure, and post-launch support.
Every client arrives in a different situation. TMS structures the engagement around where you are, not where we wish you were.
You have a product idea, a business case, or an early design. TMS takes it from requirements through architecture, development, QA, and launch. We validate scope before coding starts so you do not over-invest in a direction that needs to change. The same team that scopes the product builds it, so no context is lost between planning and execution. You get a working MVP in 8 to 14 weeks, then iterate based on real user feedback.
Your in-house engineers have a roadmap but not enough capacity. TMS embeds additional developers, architects, or QA engineers into your team, working in your process, your codebase, and your sprints. There is no separate TMS silo. Our engineers attend your standups, use your tools, and report to your PM. You scale capacity up or down as your sprint cadence demands, without the recruitment timeline.
You have inherited a codebase that is slow, brittle, or unfinished. TMS conducts a technical audit first, then rebuilds or refactors what needs to change while keeping the rest running. We have done this for projects originally built by other agencies and by in-house teams that outgrew their original architecture. You get a clear diagnosis, a prioritized remediation plan, and a team that can execute it without starting from scratch.
Nine categories of web applications TMS has delivered in production. Each one is a different engineering problem, and we have shipped real products in all of them.
Multi-tenant architecture, subscription billing, role-based access, and API-first design. We handle the full SaaS lifecycle: onboarding flows, plan management, usage metering, and tenant isolation. Amelia, an enterprise booking SaaS built by TMS, has 1.5M+ active installations.
Workflow automation, pipeline management, customer data modeling, and third-party integrations. We build CRMs that match your sales process instead of forcing your team into a generic tool. Custom fields, automated triggers, reporting dashboards, and integrations with email, calendar, and billing systems.
Real-time availability, payment processing, calendar sync, and multi-location support. We handle timezone complexity, double-booking prevention, recurring schedules, and group bookings. Amelia is the proof point: an enterprise appointment booking platform with 1.5M+ active installations across 50+ countries.
Dashboard design, data ingestion pipelines, chart libraries, and export functionality. We build tools that make complex data understandable for non-technical users. WPDataTables, a data visualization platform built by TMS, has 2.7M+ active installations and handles complex data ingestion and chart rendering at scale.
Product catalog, cart and checkout, payment gateway integration, and inventory management. We optimize for conversion: fast page loads, smooth checkout flows, and mobile-first design. Integrations with Stripe, PayPal, and shipping providers are standard, not add-ons.
Course management, progress tracking, video hosting integration, and certification workflows. We build learning platforms that handle content drips, quizzes, student progress, and instructor dashboards. SCORM and LTI integrations available for institutional requirements.
Rule-based workflows, document processing, notification systems, and ERP integrations. We build tools that remove manual work from your team's day. If a process happens the same way more than three times, it should be automated, and we build the systems that do it.
User profiles, connection graphs, activity feeds, messaging, and moderation tools. We build platforms that connect professionals around shared interests or industries, with the social features users expect and the moderation tools administrators need.
Media storage and transcoding, streaming, CDN integration, and access control. We handle the infrastructure challenges of video and audio platforms: encoding pipelines, adaptive bitrate streaming, and storage cost optimization without sacrificing playback performance.
What actually happens after you contact us. Six phases, each with a concrete deliverable. You see progress every few days, not just at the end.
Requirements, scope, and architecture decisions.
We map business goals, user needs, and technical constraints into a validated product scope. You leave this phase with a clear understanding of what is being built, why, and what it will cost. No coding happens until scope is confirmed.
Tech stack, data model, API design, infrastructure.
Our senior engineers design the system architecture: database schema, API contracts, service boundaries, and deployment topology. Decisions are documented so the whole team builds against the same blueprint.
Two-week sprints with working software each cycle.
We build in two-week sprints. Every sprint delivers working software you can test, not a status report. UI/UX design runs alongside development, not before it, so interfaces are validated against real data.
Embedded testing throughout, not a phase at the end.
QA is built into every project, not added at the end. QA engineers define acceptance criteria during planning and validate each feature before it leaves the sprint. Automated tests run on every commit.
CI/CD pipeline, staging environment, production launch.
We deploy through automated CI/CD pipelines with staging environments for final validation. Production launch is staged and monitored. Rollback plans are in place before any deployment, so a failed release never means downtime.
Monitoring, feature development, and platform upgrades.
After launch, we offer ongoing support, feature development, and platform upgrades. The same team that built your application can maintain it, with zero knowledge transfer delay.
The technologies we work with in production, organized by layer. If your stack is not here, ask. We evaluate new frameworks when client requirements demand it.
React, Vue.js, Angular, Next.js, and Nuxt. We build component-based, type-safe frontends with TypeScript as the default. State management, server-side rendering, and progressive web app support are all in-house capabilities, not experimental add-ons.
Node.js, PHP, Symfony, Laravel, and Python/Django. We choose the backend framework that fits your team's skills and your product's long-term needs, not the one we happen to prefer. API-first design is standard across all backends we build.
PostgreSQL, MySQL, MongoDB, and Redis. We model data for query patterns the application will actually run, not for theoretical elegance. Caching strategies, indexing, and query optimization are part of the architecture, not performance afterthoughts.
AWS, Google Cloud Platform, Docker, and Kubernetes. We deploy with infrastructure-as-code, so environments are reproducible and deployments are automated. Auto-scaling, load balancing, and monitoring are configured from day one.
REST, GraphQL, and WebSockets. We design APIs as contracts, not afterthoughts. Third-party integrations include Stripe, PayPal, Twilio, SendGrid, AWS services, and custom partner APIs. Every integration includes retry logic, error handling, and monitoring.
WordPress and ProcessWire for content-driven applications. We have built and maintain plugins with millions of active installations, so CMS integration is not a side capability. It is a core competency with a proven track record at scale.
The question every prospective client is implicitly asking. Here is the direct answer.
Engineering rates 40 to 60% below Western EU and US agencies, with no compromise on code quality, delivery process, or communication. You get senior engineers and structured sprints at a rate that does not consume your entire budget before the product ships.
Belgrade and Bucharest are in CET+1, which overlaps cleanly with Western Europe and US East Coast morning hours. You get real-time collaboration during your working day, not async updates waiting from a team 12 hours away.
40+ engineers with 7+ years average industry experience. You are not assigned to junior developers learning on your budget. Senior engineers handle architecture decisions and complex implementations by default.
English-fluent team, direct communication with engineers, no account management middlemen. You talk to the people building your product, not a project manager who relays messages. Decisions are made in real time, not over a 48-hour email cycle.
