Custom E-commerce Development

An online store built for your business model, not a template.

We build custom e-commerce platforms for businesses whose sales model outgrows Shopify, WooCommerce, or Shoptet. That usually means customer-specific pricing, B2B ordering with approvals and net terms, tight stock sync with your warehouse and ERP, or selling one catalog across several channels. We design the storefront, checkout, and admin around how you actually sell, then wire it into your accounting, carriers, and product feeds. You own the code, avoid per-sale platform fees, and control the roadmap.

The problem

Template stores limit how you sell

Shopify, WooCommerce, and Shoptet work well for straightforward retail stores. But once your business relies on customer-specific pricing, B2B approval workflows, complex product variants, or tight integration with your warehouse and ERP, a generic platform becomes the bottleneck. You pay for plugins to patch gaps, build workarounds for checkout limits, and lose margin to per-sale fees on every order. And because you cannot control the full buying journey, the customer experience suffers too. A custom platform removes those constraints and gives you a store that sells exactly the way your business does.

Checkout that does not match your real pricing or sales model
Customization only by stacking expensive plugins and extensions
Per-sale platform fees taking a cut of every order
No real control over the experience, from product pages to post-purchase
Hard or impossible real-time sync with your ERP, warehouse, and accounting
Scaling pain as the catalog grows or you expand into new markets and channels
Use cases

Who is this for

We work with businesses across industries. Here are some of the most common scenarios where this service delivers real results.

01

B2B wholesale portals

Ordering portals for wholesale and distribution with customer-specific pricing, volume discount tiers, approval workflows, and integration with invoicing and ERP. B2B buyers get self-service ordering that cuts the manual load on your sales team.

02

Product configurators

Stores where customers build or customize products before ordering: furniture with fabric choices, industrial components with specifications, or print-on-demand items. We build visual configurators that price dynamically and feed valid configurations straight into production.

03

Subscription and recurring commerce

Platforms for subscription boxes, replenishment models, or membership stores. Automated billing cycles, self-service subscription management, and stock forecasting based on active subscriptions. Customers can pause, skip, or change deliveries without contacting support.

04

Multi-vendor marketplaces

Marketplaces where several sellers list and manage their own products. Vendor onboarding, commission tracking, payout management, and separate dashboards for vendors and the operator, built to scale as you add sellers and categories.

05

Headless commerce for multi-channel selling

A headless backend powering your website, mobile app, kiosks, and third-party channels from one catalog and order system. Content teams manage each frontend independently while the commerce engine handles pricing, stock, and checkout logic everywhere.

06

Complex catalog retailers

Stores with thousands of SKUs, deep variant trees, or products that need specifications and compatibility checks. We build catalog structures, filters, and search that make large inventories navigable. A fit for parts distributors, electronics retailers, and specialty suppliers.

Key benefits

Why this approach works

01

Checkout that matches how you sell

Customer-specific pricing, volume tiers, B2B approval steps, net-30 or net-60 terms, split payments. We build the checkout your sales model needs instead of forcing it through a template that assumes one price for everyone and payment up front.

02

Do the transaction-fee math

Hosted platforms usually combine a monthly subscription with a cut of each sale or a payment-processing markup. On a custom build you pay only your payment gateway and hosting. Add up a year of platform plus per-sale fees, compare it to a one-time build, and the point where custom wins becomes a question of order volume, not opinion.

03

Real-time sync with your ERP and warehouse

Orders, stock, prices, and invoices move between the store and your back office automatically. We connect to Czech accounting and ERP systems like Pohoda, ABRA Flexi, and Money S3, so stock levels and order status stay correct without anyone re-keying data.

04

Architecture you control

Headless or monolith, we pick the setup that fits your channels and team, and you own the source code either way. No vendor lock-in, no forced plan upgrades, and no feature you depend on being deprecated out from under you.

05

Fast pages, measured by Core Web Vitals

The storefront is server-rendered and free of the unused template code and third-party scripts that slow hosted stores down. That shows up directly in Core Web Vitals, which affects both your search ranking and how many visitors actually reach checkout.

06

Built for the Czech market

Zasilkovna (Packeta), PPL, and other carriers for delivery and pickup points. Product feeds for Heureka, Zbozi.cz, and Glami. Invoicing through Fakturoid or your ERP. Multi-language and multi-currency when you sell abroad, from one catalog and one backend.

What we build

A solution designed for your business

Custom storefront

A storefront built for your brand and catalog, server-rendered for both speed and search. We drop the template weight and third-party bloat, so pages load fast on mobile and every screen, from category to product detail, is yours to shape.

Payment and checkout

Checkout wired to the gateways your market uses: Stripe, GoPay, Comgate, PayPal, bank transfer, and cash on delivery. We add B2B net terms, installments, or recurring billing where you need them, and keep the flow short to cut cart abandonment.

Order and inventory management

Automated order processing, real-time stock across one or several warehouses, backorder handling, and fulfillment rules by product or region. Every order syncs to your inventory and accounting, so nothing gets entered twice.

Czech accounting, logistics, and feed integrations

Two-way sync with Pohoda, ABRA Flexi, or Money S3, invoicing through Fakturoid, shipping and pickup points via Zasilkovna (Packeta) and PPL, and product feeds tuned for Heureka, Zbozi.cz, and Glami. The integrations Czech stores actually run on, built in rather than bolted on.

Product catalog and search

A flexible catalog that handles simple items, configurable products, bundles, and deep variant structures. Faceted search and smart filters help customers find what they need, and structured attributes and taxonomies keep the catalog clean as it grows to thousands of SKUs.

Analytics and reporting

Track what drives the business: revenue by channel, conversion by source, average order value, cart abandonment points, and customer lifetime value. Dashboards fit what your team needs to see, and data feeds into your existing analytics or a custom reporting layer in the admin.

How we work

From idea to working system

01

Understand your model

We map your products, pricing rules, customer segments, and fulfillment in detail. We pin down what makes your sales model unique and where a custom platform beats a template, which sets the foundation for everything we build.

02

Design the experience

We create wireframes and interactive prototypes for the storefront, product pages, checkout, and admin. Every screen is designed around your customers' buying behavior and your team's operations. You review and approve the design before any code is written.

03

Build and integrate

We develop the store, implement payments, connect stock and orders, and integrate your ERP, accounting, carriers, and feeds. Development runs in sprints with regular demos so you see progress and steer as we go.

04

Launch and optimize

We launch, watch real-world performance, and track conversion from day one. After launch we use real behavior to smooth friction points and add the features that move sales. Ongoing support keeps the platform healthy.

Pricing

What influences cost

E-commerce pricing depends on catalog complexity, checkout requirements, the number and depth of integrations, and how much of your business model has to be custom. We scope every project individually after a free consultation.

from 100,000 CZK
  • Product catalog size, variant structure, and configurator complexity
  • Custom checkout, payment gateway integrations, and B2B billing logic
  • Depth of ERP and warehouse sync: Pohoda, ABRA Flexi, Money S3, real-time stock, multiple warehouses
  • Logistics and feeds: Zasilkovna, PPL, Heureka, Zbozi.cz, Glami
  • Multi-language, multi-currency, and multi-market requirements
  • Admin panel complexity and custom reporting
  • Migration from an existing platform including data, URLs, and SEO

Custom e-commerce is not the right call for everyone. If you sell standard products at one price on a single channel, Shopify, WooCommerce, or Shoptet will serve you well and cost less to start. Custom pays off when customer-specific pricing, B2B workflows, deep ERP or warehouse sync, or multi-channel selling push a template platform past its limits.

Frequently asked questions

Common questions answered

Start with four questions. First, pricing: if different customers pay different prices, or you need B2B tiers, quotes, or net terms, template platforms fight you. Second, integration depth: an occasional export to accounting is fine on any platform, but real-time two-way sync with Pohoda, ABRA Flexi, or a warehouse system usually needs custom work or heavy middleware. Third, channels: selling one catalog across web, app, marketplaces, and wholesale points toward a headless custom backend. Fourth, volume: at a few hundred to low thousands of orders a month, per-sale fees and plugin subscriptions start to rival the cost of owning your own build. If none of these apply, stay on Shopify, WooCommerce, or Shoptet. If several do, custom is usually cheaper over a few years and far less frustrating.

Add up what a hosted setup costs you in a year: the monthly plan, any percentage the platform takes per sale, the payment-processing markup above the raw gateway rate, and the paid plugins you need to cover gaps. Compare that annual figure to a one-time custom build plus its hosting and maintenance. Because platform fees scale with revenue while a custom build is mostly fixed, there is an order volume where the lines cross. Below it, hosted is cheaper. Above it, you are paying rent on software you could own. We run these numbers on your real order volume before recommending anything, and we tell you honestly if custom does not pay off yet.

The systems Czech stores actually run on. For accounting and ERP: Pohoda, ABRA Flexi, and Money S3, with two-way sync for orders, invoices, stock, and customers. Invoicing through Fakturoid. Shipping and pickup points via Zasilkovna (Packeta) and PPL, with label printing and tracking. Product feeds tuned for Heureka, Zbozi.cz, and Glami, including parameters and availability. If you use something else, we integrate against its API or file exchange during scoping.

The common ones are Stripe, GoPay, Comgate, PayPal, bank transfer, and cash on delivery. We can also add installments, recurring billing, split payments, and B2B terms such as net-30 or net-60 invoicing. The right gateway depends on your market, your customers' habits, and your transaction volume, since fee structures differ.

Both are valid; the choice follows your channels and team. A monolith, one application serving the storefront and admin, is simpler to build and run when the web store is your main channel. Headless, where the commerce backend is separate from one or more frontends, makes sense when you sell the same catalog through a website, a mobile app, and marketplaces, or when a content team needs to move fast independently of the commerce logic. We recommend the simpler option unless a real need justifies the extra moving parts, and you own the code either way.

Orders do not fire straight into your ERP and hope for the best. We put a queue between the store and the back office, so a slow or offline ERP never blocks a sale, and we make each sync idempotent, so a retry cannot create a duplicate order or invoice. Stock flows back from the warehouse to the storefront on a schedule or by webhook, and a reconciliation step flags anything that does not match instead of failing silently. The result is order status and stock levels you can trust without manual checking.

Yes, it is one of our core strengths. We build portals with customer-specific pricing, volume discount logic, quote requests, approval chains, net payment terms, and integration with your invoicing and ERP. B2B buyers get self-service ordering while your business rules are enforced automatically, which cuts the manual load on your sales team.

Performance and SEO are in the architecture, not bolted on later. Server-side rendering with Next.js, automatic image and asset optimization, and a codebase free of unused scripts give fast loads and strong Core Web Vitals. Clean semantic HTML, correct canonical and hreflang tags, and structured product data let search engines crawl and index the catalog properly. Faster stores rank better and convert better.

Yes. We migrate your product catalog, customer accounts, order history, and content, and set up URL redirects so your search rankings and existing links survive the move. The migration plan is part of scoping, so there are no surprises during cutover.

Usually 2 to 4 months to the first live version. We ship core selling first, catalog, checkout, payment, and order management, so you can start taking orders, then add features like loyalty, deeper analytics, or extra channels based on real usage.

Yes. Multi-language and multi-currency are built into the architecture: localized product content, currency-specific pricing, regional tax rules, and language-aware SEO with correct hreflang tags. Adding a market later does not mean rebuilding the store.

We model the data around your catalog. Products with dozens of variants, configurable items with dependent options, bundles, or specifications with compatibility rules all fit cleanly. Faceted search, smart filters, and structured product data keep large catalogs, thousands of SKUs, easy to navigate.

We offer support plans covering security updates, monitoring, fixes, and new features. Because you own the platform, you are not locked to us, but most stores take a plan since they keep evolving with new products, promotions, and integrations.

E-commerce & Automation

Automated order processing for e-commerce

A Czech e-commerce company selling consumer goods across multiple channels replaced manual order processing with a unified automated platform. The system connects their web store, Heureka, Mall.cz, and wholesale partners into a single workflow that handles everything from order intake to shipping label creation. With over 150 orders per day flowing through the platform, the operations team shifted from repetitive data entry to focusing on supplier relationships and catalog growth.
