Excel and generic software = limits and constant inefficiencies.

When your business is unique but your tools are generic, you waste time adapting instead of scaling. A custom web app perfectly adapts to your processes, connects your systems, and grows with you. Zero compromises.

What a Web App Is and When It Makes Sense

A web app is a software application accessible via browser (Chrome, Safari, Firefox) that works like a desktop program but is hosted on cloud servers. Unlike a static website, a web app handles complex data, custom workflows, roles/permissions, and integrations with other business systems.

When should you choose web app development instead of a website or mobile app?

  • Complex internal processes: Order management, inventory, custom CRM, multi-step approval workflows.
  • B2B portals: Reserved area for clients/suppliers to view data, download documents, and place orders.
  • SaaS (Software as a Service): Multi-tenant platform with subscriptions to monetize a digital service.
  • Dashboards and Reports: Real-time data visualization from databases/ERP with filters, exports, and charts.
  • System integrations: Connect ERP ↔ E-commerce ↔ CRM ↔ Accounting via web middleware.

Web App vs Website: Website = static content, information. Web App = business logic, data CRUD, workflows.
Web App vs Mobile App: Web = accessible anywhere via browser, one codebase for all devices. Mobile = store installation, access to device features (GPS, camera), better performance.

Web App Development for Businesses: Company Portals and Dashboards

We specialize in custom web app development for businesses with specific needs that standard software does not cover.

Company & B2B Portals

Reserved area for clients/suppliers/employees: viewing orders, invoices, documents, support tickets. Custom roles and permissions. Integration with ERP/CRM for always up-to-date data.

Examples: Supplier portal for submitting quotes, client portal for shipment tracking, company extranet.

Dashboards & BI Tools

Real-time data visualization from databases/ERP: KPIs, charts, exportable reports (PDF/Excel). Custom filters, drill-down, automatic alerting on anomalies. Live updates every 5 min.

Examples: Multi-location sales dashboard, production reporting, marketing analytics with ROI per channel.

Multi-Tenant SaaS

Cloud platforms where each client has their own isolated area (tenant) with dedicated data. Subscription billing (Stripe), automated onboarding, per-user analytics, public APIs.

Examples: Industry-specific CRM, marketing automation tool, e-learning training platform.

Custom Management Software

Management software for when standard CRM/ERP systems are too generic or expensive. Management of clients, orders, inventory, documents, approval workflows, custom reporting.

Examples: Construction project management, legal-sector CRM, multi-warehouse inventory.

Workflows & Automation

Digitizing manual processes: leave requests, budget approvals, employee onboarding, ticket management. Automatic email notifications, escalation, complete audit trail.

Examples: Multi-level order approval system, customer feedback management, internal ticketing.

Integrations & Middleware

A web app that bridges existing systems: data synchronization between ERP ↔ E-commerce, automatic import/export, format transformation, notifications on critical events.

Examples: Inventory sync Shopify ↔ SAP, order import from marketplace to management software, centralized data hub.

SaaS Development: Custom Cloud Platforms

Software as a Service (SaaS) is the most scalable software distribution model on the market: your solution is hosted in the cloud and accessed by clients via subscription, with no installations. We build multi-tenant SaaS platforms tailored to you — from a validated MVP all the way to enterprise products — designed to grow with your client base without having to rewrite the code.

What a custom SaaS project includes

  • Multi-tenant architecture: Each client has their own isolated data space (separate schema or row-level security). No cross-tenant contamination, maximum security.
  • Subscription billing: Stripe integration with monthly/annual plans, free trial, automatic upgrade/downgrade, billing management and dunning.
  • Automated onboarding: Self-service registration, guided workspace setup, welcome emails, in-app tutorials. The client is up and running in minutes.
  • Per-tenant analytics dashboard: Each client sees their own metrics in real time. As the vendor, you get an aggregated view across all tenants to monitor growth and churn.
  • Public APIs and webhooks: Let your clients integrate your SaaS with their systems. OpenAPI/Swagger documentation included.

SaaS verticals where we have experience: HR and payroll, marketing analytics, e-learning, project management, industry-specific CRMs. Our approach always starts from a solid MVP — functional, secure, and monetizable — before scaling toward enterprise features.

Typical Features (Roles, Workflows, Reports, Export)

What does turnkey web application development include?

  • Reserved Area and Roles: Secure login, user management with roles/permissions (Admin, Manager, Operator, Client). Data visibility by role. Complete audit log.
  • Full CRUD: Create, Read, Update, Delete on business entities (clients, orders, products, documents). Validated forms, advanced search, filters, sorting.
  • Custom Workflows: Custom statuses (Draft → Pending Approval → Approved), automatic transitions, email/push notifications, escalation when blocked.
  • Reports and Analytics: Dashboards with KPIs, charts (Chart.js, D3.js), date/category filters, PDF/Excel/CSV export. Scheduled automatic reports via email.
  • File Upload and Management: Document upload (PDF, Excel, images), cloud storage (AWS S3), in-app preview, versioning, per-file permissions.
  • Notifications: Automatic emails (SendGrid, AWS SES), in-app notifications (toast, badges), SMS (Twilio) for critical events, daily/weekly digests.
  • Search and Filters: Full-text search (Elasticsearch), multi-field filters, saving favorite filters, exporting search results.
  • Responsive Design: Works on desktop, tablet, smartphone. Adaptive UI, no app to install, just a browser.

Backend, Database, and API Integrations

The heart of a web app is the backend: business logic, database, external integrations, authentication, APIs.

Typical Backend Stack

  • API Server: Node.js (Express/NestJS), Python (Django/FastAPI), PHP (Laravel)
  • Relational Database: PostgreSQL, MySQL for structured data with complex relationships
  • NoSQL Database: MongoDB for flexible data, JSON documents
  • Cache: Redis for performance, user sessions, rate limiting
  • Search Engine: Elasticsearch for fast full-text search
  • Queue: RabbitMQ, AWS SQS for asynchronous jobs (email, export, batch import)

Common API Integrations

  • ERP: SAP, Odoo, Microsoft Dynamics (SOAP/REST API)
  • CRM: Salesforce, HubSpot, Zoho, Pipedrive
  • E-Commerce: Shopify, WooCommerce, Magento, PrestaShop
  • Payments: Stripe, PayPal, Braintree for SaaS billing
  • Accounting: Fatture in Cloud, TeamSystem, Xero
  • Email/SMS: SendGrid, AWS SES, Twilio

Supported Architectures

Depending on the complexity of the project, we propose scalable architectures:

  • Monolith: Frontend + Backend in a single deployment (Next.js, Laravel). Ideal for MVPs and small-to-medium projects.
  • Decoupled (API + Frontend): Backend API (NestJS, Django) + Frontend SPA (React, Vue). Independent scalability.
  • Microservices: Separate services per business domain (Auth, Orders, Billing, Analytics). For enterprise SaaS.

Security and Performance (Auth, Permissions, Logging)

Security is not an optional "extra": it is foundational. Every web app includes standard protections.

Authentication and Authorization

Secure login with password hashing (bcrypt/Argon2), JWT tokens, refresh tokens. Support for 2FA (two-factor authentication) and SSO (Single Sign-On) with Azure AD/Okta if required. Granular roles and permissions: who can view/edit/delete what.

Attack Protection (OWASP Top 10)

Protection against SQL Injection (parameterized queries), XSS (input sanitization), CSRF tokens, rate limiting against brute-force, mandatory HTTPS (SSL/TLS), security headers (CSP, HSTS).

Audit Trail and Logging

Complete log of user actions: who changed what, when, from which IP. Log retention for regulatory compliance (GDPR, SOX). Audit access only for authorized admins.

Performance and Caching

Database query optimization (indexes, explain plan), Redis caching for frequently read data, CDN for static assets, lazy loading, pagination instead of "load everything". Goal: API response < 200ms.

How We Work: Discovery → UX → Build → QA → Deploy

Step 1: Discovery & Analysis

Initial workshop: business goals, target users, processes to digitize, systems to integrate. Deliverable: functional analysis document, user stories, preliminary data model.

Step 2: UX/UI Design

Low-fidelity wireframes (page structure), high-fidelity mockups (visual design), interactive prototype (Figma). You approve the design before coding begins. Rapid iterations on feedback.

Step 3: Build (Agile Sprints)

Iterative development in bi-weekly sprints. Each sprint: working demo on staging, QA testing, incremental deployment. Dynamic backlog: you can re-prioritize features at every sprint.

Step 4: QA & Testing

Functional testing (all user stories), regression testing, performance (load testing with 1,000+ concurrent users), security audit (penetration testing), UAT with your team. Critical bug fixes before production.

Step 5: Deploy & Maintenance

Cloud infrastructure setup (AWS, Azure, GCP) or on-premise, CI/CD pipeline, monitoring (Datadog, New Relic), automatic backups, SSL. Team training. Post-launch support with guaranteed SLAs.

Timelines and Costs (Quote Drivers)

The quote depends on functional complexity, number of entities/screens, integrations, data migration, and required SLAs.

Factors that influence the cost:

  • Logic complexity: Number of entities (clients, orders, products...), database relationships, business rules
  • Roles and permissions: How many user roles? Granular permissions on individual functions?
  • Integrations: How many external systems to connect? (ERP, CRM, payments, email...)
  • Data migration: Import from legacy systems (Excel, Access, VB6)? Complex ETL?
  • Custom reporting: Dashboards with real-time charts? Custom PDF/Excel exports?
  • SLA and uptime: Need 99.9% high availability? Disaster recovery? Increases infrastructure costs

Indicative ranges:

  • • Basic B2B portal (data viewing, simple roles): €12,000 - €20,000
  • • Medium complexity web app (CRUD, workflows, integrations): €25,000 - €45,000
  • • Multi-tenant SaaS or complex management software: €50,000 - €100,000+

Includes: analysis, UX/UI design, frontend/backend development, database, integrations, QA, deployment, documentation, 3 months of support.

Web App vs Mobile App: Which Is Better?

When should you choose web app development instead of a mobile app?

✓ Choose a Web App if...

  • • Primary use from desktop/office (B2B, back-office)
  • • No need for device sensor access (GPS, camera, NFC)
  • • Limited budget: one codebase for everything (desktop, tablet, mobile browser)
  • • Frequent updates: instant deployment without store approval
  • • Complex system integrations (ERP, business databases)

✓ Choose a Mobile App if...

  • • Primary use on the go (field service, delivery, consumer)
  • • You need GPS, camera, native push notifications, robust offline mode
  • • You want an icon on the device home screen for brand awareness
  • • Critical performance (gaming, AR, video processing)
  • • Monetization via the App Store (in-app purchases, Apple/Google subscriptions)

Note: In many cases the optimal solution is hybrid: a web app for the back-office + a mobile app for users in the field. The two share the same backend API.Discover our mobile app development service →

What's the difference between a web app and a website?

Website = static content, company info, blog. It does not manage processes. Web app = business logic, data CRUD, workflows, system integrations, roles/permissions. It's software accessible via a browser, not an informational site.

Web app or mobile app: which is better?

Web app if primary use is desktop/office (B2B, back-office), GPS/camera not needed, limited budget. Mobile app if used on the go, needs robust offline mode, push notifications, or home screen presence. Often the solution is hybrid: web app for back-office + mobile app for the field.

Do you handle backend, databases, and API integrations?

Yes, all included. We build full backends (Node.js, Python, NestJS, PHP), databases (PostgreSQL, MySQL, MongoDB), and integrations with ERPs (SAP, Odoo), CRMs (Salesforce, HubSpot), payments (Stripe), email, and analytics.

How do you handle roles/permissions and security?

Granular role system (Admin, Manager, Operator...), permissions on single functions (who can create/read/update/delete). Secure authentication (JWT, bcrypt), SQL injection/XSS/CSRF protection, mandatory HTTPS, full audit log, GDPR compliance.

Who owns the source code?

You do, 100%. We provide frontend + backend source code, database schemas, Git repository access, and full technical documentation. No vendor lock-in. You can continue development internally or with other providers.

How does maintenance and updates work?

Includes 3 months post-launch support (bug fixing, minor tweaks). Then monthly maintenance SLAs starting at €500/month: priority bug fixing, minor feature updates, security patches, proactive monitoring, verified backups. Or on-demand interventions.
