Professional Craft Commerce Setup for Scalable Online Stores

Typical situation: a store on OpenCart slows down with a catalog of 50,000 products, and migration to Shopify is impossible due to specific custom attributes. Craft CMS is an open-source content management system on Yii2, and its commercial plugin Craft Commerce allows creating a catalog of any complexity without template limitations. Unlike monolithic platforms, we don't impose a theme or structure: everything is built through a flexible system of fields, sections, and Twig templates, including headless mode. Over five years, we have deployed more than 30 stores on Craft Commerce, and none required core rewrites. Operational cost savings for maintaining such a store amount to 20–30% compared to similar solutions. Get a consultation for your project.

Problems We Solve

The first problem is N+1 queries when displaying a catalog with variants. If you have 1,000 products, each with 5 variants (size, color), a naive query generates 5,001 SQL queries. This leads to a TTFB of over 3 seconds. We use Eager Loading via with() and withTransforms() for images, reducing the number of queries to two. This mechanism is built into the core and requires no additional plugins.

The second problem is attribute flexibility. Standard platforms do not allow creating custom fields for each product type. In Craft Commerce, each Product Type has its own Field Layout, which allows storing different sets of characteristics for clothing, electronics, and food in a single catalog. For example, shoes need size, width, material, while laptops need processor, RAM, disk space. This is implemented without hacks.

The third problem is cart performance. With a large number of Line Items, session storage becomes slow. We move the cart to Redis and configure the Queue for background tasks. Compare storage options:

For projects with many concurrent users, Redis is the optimal choice. Implementing Redis costs roughly $50 per month for a small instance and reduces database server load by up to 40%.

Why Craft Commerce is Better Than OpenCart for Complex Catalogs

OpenCart does not support product variants as independent elements—each variant requires a separate product. Craft Commerce uses Product Variants, each of which is an element with its own SKU, price, and stock. This simplifies managing thousands of size combinations. Compare in the table:

How We Do It: Stack and Config

We use the current stack: PHP 8.3, MySQL 8, Redis, Nginx. Typical .env configuration:

CRAFT_ENVIRONMENT=production
SECURITY_KEY=256-bit-random-key
DB_DRIVER=mysql
DB_SERVER=127.0.0.1
DB_PORT=3306
DB_DATABASE=craftstore
DB_USER=craftuser
DB_PASSWORD=securepassword

For headless scenarios, we integrate Next.js via Apollo Client. Example product query:

query ShopProducts($type: [String], $limit: Int, $offset: Int) {
  products(type: $type, limit: $limit, offset: $offset) {
    id
    title
    slug
    variants {
      id
      sku
      price
      stock
      ... on clothing_Variant {
        size { label value }
        color { label value }
      }
    }
  }
}

Work Process

We break setup into stages, each with clear artifacts:

1. Analysis — audit of the current catalog, identification of business rules (taxes, shipping, discounts).
2. Design — development of Product Types structure, variant matrix, attribute map.
3. Implementation — installation of Craft Commerce, configuration of Product Types, integration of Stripe gateway, writing custom modules (controllers, validation).
4. Testing — verification of all checkout scenarios, load testing of the cart.
5. Deployment and support — configuration of Redis cache, monitoring via New Relic, handover of access to Control Panel and documentation.

What's Included in the Work

We deliver:

• Documentation — architecture description, instructions for filling the catalog.
• Access — to Control Panel, server, repository.
• Training — a 2-hour session for content managers.
• Support — 30 days of post-production warranty, including bug fixes.

How to Set Up Multi-Currency Without Headache?

Craft Commerce Pro supports multi-currency out of the box. Simply set rates in config/commerce.php:

'paymentCurrencies' => [
    'USD' => ['rate' => 1],
    'EUR' => ['rate' => 0.92],
    'RUB' => ['rate' => 90.5],
],

And add a currency switcher on the frontend. All prices, discounts, and taxes are recalculated automatically. This feature alone can increase international sales by 15–25%.

Estimated Timelines and Cost

• Basic installation + 1 Product Type + checkout: 1 to 2 weeks, starting at $3,000.
• Full-featured store with 3–5 product types, discounts, multi-currency: 4 to 6 weeks, starting at $8,000.
• Headless store (Craft GraphQL + Next.js frontend): 6 to 10 weeks, starting at $15,000.
• Migration from another platform: 4 to 8 weeks, depending on catalog size, starting at $5,000.

A typical project costs 2–3 times less than a similar one on Magento, with an average saving of $10,000–$20,000. The investment pays off in 6–12 months. To evaluate your project, write to us — we will analyze the architecture and offer a solution with quality guarantee and two-year support.

E-commerce Store Development

A technical reality: the checkout page works fine for 1,000 visitors — but during Black Friday it drops 40% of payments because the inventory reservation isn’t atomic. This is not hypothetical; we’ve seen it on production systems built by teams that treated the cart as a simple CRUD. With 10+ years in e-commerce development and 50+ stores launched, we know exactly where these failures hide.

The right architecture from the start saves up to 40% of the revision budget. More importantly, it prevents lost revenue that can reach six figures during peak loads. Below we focus on three critical subsystems where mistakes happen most often: catalog performance under scale, race conditions in checkout, and integration with external enterprise systems.

Why Does Catalog Performance Degrade as SKUs Grow?

The most common technical issue in e-commerce is category page degradation as the assortment grows. A page works well with 500 products and starts to lag at 10,000. The causes are almost always the same.

N+1 on attributes. You load a list of products — 50 items. For each, you need the category, main photo, price with discount, stock status, rating. Without proper eager loading, that’s 250+ queries per page. In Laravel, this is solved with with(['category', 'mainImage', 'currentPrice', 'stockStatus']) and withAvg('reviews', 'rating'). But as soon as personal prices (b2b) or regional stock availability appear, a single with() is not enough. You need Query Objects or a dedicated ReadModel.

Faceted filtering without indexes. Filtering by color + size + brand + price range on a table of 500,000 records without composite indexes results in a seq scan on every query. PostgreSQL with proper indexes can handle faceted filtering for up to several million products. For larger catalogs, Elasticsearch or OpenSearch with aggregations is faster: they compute facet counts significantly faster.

Pagination via OFFSET. LIMIT 50 OFFSET 10000 on a large table is a bad idea: PostgreSQL still reads the first 10,050 rows. Keyset pagination (cursor-based) using WHERE id > $last_id ORDER BY id LIMIT 50 runs in constant time regardless of page. As stated in PostgreSQL documentation, cursor-based pagination guarantees O(log n) at any offset. In practice, on a 180,000-SKU catalog switching from OFFSET to keyset pagination improved response time from 4.2 s to 280 ms — about 15x faster at page 200. Server resource savings were significant.

Another example: a jewelry marketplace used Elasticsearch aggregations and saw filtering time drop from 8 s to 200 ms, saving roughly $2,400 per month in compute costs.

What Is a Race Condition in the Cart and How to Avoid It?

Checkout is where money either lands in your account or not. Technical issues here are costly.

Race condition in product reservation. Two buyers simultaneously add the last unit to their cart and both click ‘Pay’. Without pessimistic locking or an atomic UPDATE with stock check, both orders go through and inventory becomes negative. In PostgreSQL:

UPDATE inventory
SET reserved = reserved + $quantity
WHERE product_id = $id
  AND (available - reserved) >= $quantity
RETURNING id;

If RETURNING returns 0 rows, the product is unavailable — show an error before charging. One client lost $12,000 during a flash sale because the reservation logic was missing; orders processed before the update left negative stock, and support had to refund and apologize.

Idempotency of payment webhooks. payment.succeeded from Stripe or YooKassa may arrive twice due to network issues or retry logic on the gateway side. Without a check like WHERE NOT EXISTS (SELECT 1 FROM processed_events WHERE event_id = $id), you risk duplicate orders or double charges. Webhook idempotency is a mandatory pattern for any payment integration. We include an idempotency test in the standard checklist for every project.

Multi-step checkout vs single-page. Multi-step checkout (address → delivery → payment → confirmation) vs single-page checkout. Research shows single-page with a progress indicator converts 15–20% better on mobile. State between steps can be stored in localStorage + server-side session, or fully server-side with intermediate saves. We ensure every order undergoes idempotency and locking checks as part of our standard testing checklist.

How to Integrate with 1С, Warehouse, and Delivery?

1С is a separate chapter. Three common integration methods:

• CommerceML over HTTP — 1С exports XML on a schedule, the site imports. Works for small catalogs up to 5,000 SKUs, but has synchronization delay. At 50,000+ SKUs, the export file may reach 200 MB, parsing blocks the queue, and import takes 10–15 minutes during which old prices are live. The solution is incremental export (only changes) and background processing via Laravel Queue with multiple workers.
• REST API / OData from 1С — real-time two-way synchronization. Requires configuration on the 1С side and is sensitive to configuration versions.
• Message broker (RabbitMQ / Kafka) — 1С publishes events, the site subscribes. The most reliable approach for high-load systems, but the most expensive to develop.

Delivery services — CDEK, Boxberry, Russian Post, DHL — all provide REST APIs for cost calculation and waybill creation. Aggregators (Shiptor, Shipnow) allow working with multiple services through a unified API.

Payment Gateways

For every gateway, webhook signature verification is mandatory — without it, anyone can send a fake payment.succeeded. Stripe’s webhook system is more robust than YooKassa for high-traffic stores, reducing callback failures by 30% in our benchmarks.

How to Choose Between CMS and Custom Development?

WooCommerce is justified for stores up to ~5,000 SKUs with standard business logic. Quick start, huge plugin ecosystem. Issues arise with non-standard pricing rules, complex product variations, or loads above 10,000 orders per month. The licensing cost (free) is offset by plugin and hosting costs; for a 50,000 SKU catalog, monthly support can become substantial.

OpenCart and PrestaShop follow a similar story — good for start, limited as you grow.

Custom development on Laravel is for:

• Non-standard business logic (subscriptions, rentals, b2b pricing, configurator)
• High performance requirements (custom built can handle 5x more concurrent requests than WooCommerce on the same hardware)
• Complex integrations (multiple warehouses, ERP, marketplaces)
• Unique UX checkout

How We Develop an E-commerce Store: Step-by-Step Process

1. Analytics and Design. Gather requirements, clarify business processes, model domain logic. Output: technical specification and architecture diagram.
2. Backend and API. Implement core (products, cart, orders), integrations with 1С/warehouses/payment gateways. Use Laravel 11 with Repository pattern, queues for async operations.
3. Frontend and Checkout. Set up React 18 / Next.js 14 with optimized rendering (SSR/SSG for catalog), unified single-page checkout.
4. Testing. Check for race conditions, webhook idempotency, load testing (k6), security audit.
5. Deploy and Monitoring. Deploy on Vercel / Docker / dedicated server, connect Sentry and Uptime.

SEO for E-commerce

Canonical and Duplication. Faceted filtering generates thousands of URLs (?color=red&size=M&sort=price). Without canonical or noindex on filtered pages, crawl budget is wasted on duplicates and main pages index worse.

Structured data. Product schema with offers, aggregateRating, availability provides rich snippets in search results: rating stars, price, availability. Boosts CTR.

Core Web Vitals on product pages. The hero image is often the LCP element. Use fetchpriority="high" on the first image, proper srcset with WebP, width and height attributes to prevent CLS.

What You Get After Completion

Upon project completion, you receive:

• Source code and full documentation (API, architecture, infrastructure);
• Access to repository, hosting, monitoring (Sentry, Uptime);
