B2C Portal Development with Catalog, Cart, and Personalization

A user lands on your B2C portal but never completes an order. The cart stays empty, the registration form scares them away, and pages load too slowly. This is a familiar problem to many. Our team of engineers with over five years of experience has developed a methodology for building B2C portals that solve these issues. By using horizontal scaling, asynchronous loading, and behavior-based personalization, we achieve high conversion rates and customer satisfaction. Our portals withstand 10x traffic surges without slowdowns.

A B2C portal consists of several key modules: a catalog with filtering, shopping cart, user account, payment system, integrations with delivery and CRM, and a notification system. Each module requires careful design. We use a modern stack: React/Next.js for the frontend, Laravel or Node.js for the backend, PostgreSQL and Redis for data, and Docker for infrastructure.

Recently, we developed a portal for an electronics ecommerce store. The old site on an outdated CMS couldn't handle the load: pages loaded in over 5 seconds, and the cart often lost items. We rewrote the frontend with Next.js using SSR, implemented Redis caching, and split the backend into microservices. As a result, LCP dropped to 1.2 seconds, and conversion increased by 40%.

Why B2C portals need special architectural attention?

B2C portals operate with anonymous visitors, peak loads, and require personalization. Let's focus on three key challenges.

Traffic scalability. B2C portals are subject to traffic spikes—sales, viral content. The architecture must handle 10–50x traffic growth without degradation. Solution: horizontal scaling of stateless services, CDN for static content, Redis for sessions and caching. Compared to vertical scaling, horizontal scaling is 5–10x more cost-effective.

Anonymous users. Cart, wishlist, browsing history must work before registration and persist after login. Session ID is stored in a cookie, data in Redis with a 30-day TTL.

Personalization. Recommendations like "similar items," "you viewed," "frequently bought together"—based on collaborative filtering or rule-based algorithms. For an MVP, simple rules suffice: same category, similar tags.

How we design scalable architecture?

During the analysis phase, we identify typical load scenarios and select appropriate tools: CDN for static, load balancers for API, Redis for caching. We use asynchronous task processing via queues (RabbitMQ or Redis Streams) for heavy operations like sending notifications.

Development timelines by phase

What's included in B2C portal development?

In every project we deliver a complete package:

• requirements audit and architecture design;
• design prototypes and UI/UX;
• frontend development (React/Next.js);
• backend development (Laravel/Node.js);
• integration of payments, delivery, CRM;
• testing and Core Web Vitals optimization;
• deployment and infrastructure setup;
• documentation and training for your team;
• 3-month warranty support.

Our work process

1. Analysis — study business requirements, target audience, competitors.
2. Design — create system architecture, select tech stack.
3. Development — 2-week sprints with demos for the client.
4. Testing — automated tests, load testing, security checks.
5. Deployment — launch to production, set up monitoring.
6. Support — warranty maintenance and further development.

Timelines and cost

An MVP B2C portal with catalog, cart, order placement, and user account takes 2–4 months. Extended functionality (personalization, mobile app, analytics) takes 4–7 months. The development cost is calculated individually after an audit.

Our experience and guarantees

Our team has over 5 years in the market, with more than 30 B2C portals delivered across various industries. B2C (Business-to-Consumer) is a sales model directly to the end consumer (Wikipedia). We guarantee code quality, adherence to deadlines, and full documentation. We use certified solutions and best practices.

Development of Corporate Portals and Internal Systems

We specialize in developing corporate portals — CRM, ERP, LMS, and Intranet. Each project starts not with landing page layout, but with how business rules will be embedded into the architecture: who sees which data, how 1C and accounting systems sync, how 500 contacts turn into 500,000 without performance degradation. Over 7 years, we have delivered over 40 portals for companies with 50 to 5000 employees. We will evaluate your project in two business days — just contact us.

A public website can be launched without detailed design — iteratively improved based on feedback. With a corporate portal, this approach does not work: the cost of fixing architectural decisions after launch for 200 users is incomparably higher. Therefore, we spend 70% of our time on analysis and prototyping, and write code only after the role matrix and integration scheme are approved.

Three areas where bad decisions are often made: access rights model, performance on large data, and real-time updates.

How to build a role model for 30 departments?

Access rights model. "A manager sees only their own clients, a department head sees the entire department, a director sees the whole company, but financial data is visible only to the CFO and above." This is not three roles — it's a matrix of roles, permissions, organizational units, and record ownership. Implementing it with if ($user->role === 'manager') in controllers will make the code unmaintainable after six months.

The correct approach: Spatie Laravel Permission for basic role model + Policy classes for object-level permission (can('view', $deal) checks not only the role but also ownership). For complex hierarchical structures — ABAC (Attribute-Based Access Control) instead of RBAC.

Performance on large data. CRM with 500,000 contacts, filtering by 10 fields, sorting by activity — a naive implementation yields 15-second queries. Composite indexes, denormalization of aggregates (last_activity_at on the record itself instead of MAX over related table), Elasticsearch for full-text search on contacts.

Real-time updates. Multiple employees working on the same document or task. Without WebSocket — constant setInterval with polling every 5 seconds, extra server load, update delays. Laravel Broadcasting + Pusher/Soketi or a custom WebSocket server on Node.js — for notifications and real-time changes.

CRM Systems

Typical set: contacts, companies, deals, activities, sales funnel, reports. Technically straightforward. The complexity lies in the details.

Pipeline with custom stages. Every company wants its own funnel. Stages must be configurable without deployment. Table pipeline_stages with position, color, is_final, probability — and drag-and-drop for reordering on UI (React DnD or dnd-kit).

Change history. Who and when changed a deal status, reassigned a responsible person, added a note. Audit log via Observer or spatie/laravel-activitylog. On UI — timeline with filtering by activity type.

Email integration. IMAP/SMTP for connecting corporate mailbox, automatic linking of incoming emails to contacts by email address. This works reliably only with proper handling of bounces, spam, auto-replies — filtering is required.

Why is ERP not about code but about data?

ERP is when CRM, warehouse, production, accounting, and HR are unified into a single system. Full ERP from scratch is rare (usually integrating with existing systems), but modular systems for specific businesses are common.

Key principle: financial operations must be immutable. Not UPDATE orders SET status = 'cancelled' — but creating a new record order_cancellations with a reference to the original order. This is the immutable ledger principle, which simplifies auditing and reconciliation.

Integration with 1C is almost always part of an ERP project. Two-way synchronization: from 1C to portal (directories, balances, prices) and from portal to 1C (orders, documents). RabbitMQ as an event bus between systems is more reliable than direct HTTP interaction — if 1C is unavailable, messages wait in the queue.

How are LMS structured: learning platforms?

Learning Management System — courses, modules, lessons, tests, certificates, user progress.

Video content is the most demanding part of an LMS. Storing video on your own server and serving via Nginx is a bad idea: expensive, slow, no adaptive bitrate. Correct approach: upload to S3/Cloudflare R2, transcode via AWS Elemental MediaConvert or Mux, HLS playlist for adaptive streaming via Video.js or Plyr.

Viewing progress — periodic sending of watch_position from the frontend (every 10–30 seconds), storage in Redis with periodic synchronization to PostgreSQL. Do not save every second to the database — it will kill performance.

SCORM compatibility — if integration with corporate training materials is needed. Separate module, there are ready libraries (scorm-again).

Intranet and HR Portals

Corporate intranet: news, documents, organizational structure, HR processes (vacations, requests, KPIs).

Organizational structure in the database is a hierarchical structure. Adjacency list (parent_id on each record) is simple to implement but slow for recursive queries. Nested Sets or Closure Table are faster for reading hierarchies, more complex for changes. In PostgreSQL — recursive CTEs (WITH RECURSIVE) with adjacency list — a balance between simplicity and performance.

Document and request approval — workflow engine. Simple linear approvals (employee → manager → HR → accountant) can be done without a special engine. Non-linear (parallel branches, conditional transitions, delegation) — consider ready solutions: Temporal.io for workflow orchestration or a custom state machine based on the state-machine pattern.

What is included in the work

When ordering a corporate portal development, you receive:

• Architectural documentation (ER diagrams, integration scheme, role matrix)
• Full code in a Git repository with CI/CD
• Access to infrastructure (hosting, databases, storage)
• Training for administrators and key users (2–3 sessions)
• Warranty support for 3 months after launch

Our design principles rely on official Laravel documentation on authorization (Policies) and recommendations for working with queues.
