Industry: retail & e-commerce
Retail: a store that converts, a back office that keeps up.
An online store is only finished when the warehouse, the accounting and bol.com join in. We build stores on Shopify, WooCommerce or headless that convert on mobile, and the integration layer behind them that lets orders, stock and returns flow through automatically.

E-commerce development for retail and wholesale
Dutch consumers spent €35.7 billion online in 2025, most of it on a smartphone. Yet the average online store converts below 2%: slow mobile pages, a mandatory account at checkout, no Apple Pay next to iDEAL. Meanwhile bol.com and Amazon take both margin and customer data, and since June 2025 the European Accessibility Act applies to every store.
RABZI builds online stores that perform at AAA level: Core Web Vitals in the green, a 3-step checkout and a design system that shows your brand instead of a theme. On Shopify or WooCommerce when that fits, headless on Next.js when you want to scale. For wholesalers we build B2B portals with customer pricing, volume tiers and reordering from history.
Then the back office. Store, Picqer or Monta, Exact or AFAS, Channable and Sendcloud talk to each other through one integration layer, returns portal included. No orders retyped, no stock differences between channels. Fixed price, fixed date, and the store is yours: code, data and accounts.

Retail & e-commerce: what we see.
Conversion below 2% and a cart that keeps emptying
We build a mobile store with Core Web Vitals in the green, guest checkout and iDEAL, Apple Pay and Klarna on one screen, so every half point of conversion lands directly in your revenue.
Dependent on bol.com and Amazon for your revenue
We build your own channel with SEO structure, Klaviyo flows and a loyalty program, so margin and customer data stay with you and marketplaces become an extra channel instead of your only one.
Orders, stock and returns handled manually between store, warehouse and accounting
We build an integration layer between your store, Picqer or Monta, Exact or AFAS, Channable and Sendcloud, so an order runs from purchase to packing slip, invoice and return label without manual work.
Category pages that do not rank, Google Ads that have to make up the difference
We build a technical SEO structure with structured data, hreflang and category copy that converts, so organic traffic grows and your ad budget stops being a band-aid.
An old Magento, Lightspeed or Wix that cannot keep up
We build a migration to Shopify, WooCommerce or headless that keeps your URLs, rankings and customer accounts, so you switch without a revenue dip and comply with the accessibility act right away.
B2B customers still order by email and Excel
We build a B2B ordering portal with customer-specific pricing, volume tiers, credit limits and reordering from history, connected to your ERP, so your sales desk sells instead of retypes.

Integrations we work with
— Our approach
How we approach it.
-
01
Checkout first, then the rest
We start with an audit of your current mobile checkout: load time, steps, payment methods, required fields. That is usually where the fastest return sits, before the first pixel of the new design.
-
02
Platform chosen by your back office, not the other way around
We pick Shopify, WooCommerce or headless based on your catalog, your warehouse software and your growth plans. Every choice comes with what it costs and earns you per month.
-
03
Migrating without a revenue dip
URL mapping, 301 redirects, customer accounts and order history come along. We go live at a quiet moment, with Search Console under watch and a rollback plan ready.
-
04
Measuring from the first order
Server-side tracking, GA4 and a dashboard with revenue, margin per channel and ROAS are in place at launch. You know on day 1 what the new store does, not after a quarter.

— Frequently asked questions
Questions about retail & e-commerce.
01How much does e-commerce development cost?
An online store on Shopify or WooCommerce with custom design, payment methods and basic integrations starts from €7,500 excl. VAT. A store with a custom theme, B2B features and integrations with Exact, Picqer or bol.com starts from €14,500; headless or multi-store from €29,500. Individual integrations start from €3,950. You get a fixed price and a delivery date up front, and the store is fully yours after payment.
02How long does it take to build an online store?
A Shopify or WooCommerce store with custom design goes live in 6 to 8 weeks. With B2B features, ERP integration and migration from an existing platform, count on 8 to 12 weeks; headless with PIM and multiple storefronts on 12 to 16. We work in 2-week sprints with a demo at the end, so you never wait a quarter to see something.
03Can you connect my store to Exact Online, Picqer and bol.com?
Yes. We connect stores to Exact Online, AFAS and Moneybird for invoices and VAT, to Picqer or Monta for warehouse and stock, to bol.com and Amazon via Channable or directly on the Retailer API, and to Sendcloud or MyParcel for shipping and returns. Stock stays in sync across every channel, orders flow through automatically and returns come back into accounting as credit notes.
04Shopify, WooCommerce or headless: which fits my store?
Shopify is the fastest route for D2C brands with a manageable catalog and a lot of marketing. WooCommerce suits stores already on WordPress that combine content with sales. Headless on Next.js is the choice for large catalogs, multiple countries or brands, B2B next to B2C, or when load time makes the difference. We advise based on your back office and growth plans, not on what we prefer to build.
05Does my online store have to comply with the European Accessibility Act?
Yes. Since June 28, 2025, the European Accessibility Act applies to online stores selling to consumers, with an exemption for micro-enterprises under 10 employees and €2 million in revenue. In practice this means WCAG 2.1 AA: keyboard operation, contrast, alt text, error messages in forms. We build new stores accessible from day 1 and audit existing stores from €950.
