00 / Have an online shop built · Shop development
We build online shops for retailers, from Duisburg for all of Germany. If you sell by the piece, Shopify is often enough, and we build your shop there. If you sell by the tonne, made to measure or with delivery on a set date, we build the shop ourselves. It works out quantity, delivery zone and date before anyone pays.
01 / What we build
A shop has more parts than the cart. Which ones yours needs depends on what you sell.
The categories follow what your customers look for. At Turkish Home the top menu reads Brands, Tableware & glass sets, Kitchen accessories, Trays & decor and Teapots.
View Turkish Home ↗If you sell by the tonne, you need a calculator, not a quantity field. At Baustoff Express, 4 × 2.5 meters at 20 centimeters deep comes to 2.80 tonnes of topsoil, with the price right next to it.
View the quantity calculator ↗The shop checks the address before it quotes a delivery price. At Baustoff Express that means 35 kilometers around Dinslaken. Freight is made up of a base fee, tonnage and distance.
If a truck has to come, the delivery date belongs in the checkout. Customers only see days with room left in the delivery plan. Two customers can’t book the same last slot at the same time.
Anyone buying topsoil gets turf suggested. Customers confirm with a checkbox that delivery is curbside only. The invoice arrives as an e-invoice.
Payment runs through a payment provider: Mollie at Baustoff Express, PayPal and Klarna at Turkish Home. If the price is only fixed after a follow-up question, the flow ends with an inquiry instead of the checkout.
02 / References
One shop is built from scratch, one runs on Shopify, and one is our own ordering system for restaurants. Each has a case study.
Client project · Building materials
Baustoff Express · E-commerce / configurator
Online shop for a building materials dealer in Dinslaken. It works out the tonnage from area and depth, checks the delivery area and books the delivery slot.
An order flow that works out tonnage, delivery zone, delivery date and truck on its own, instead of settling them on the phone.
Result Shopify and WooCommerce couldn’t handle these rules. So the shop is built with Laravel, with its own admin area for the retailer.
Client project · Home decor
Turkish Home · Shop / e-commerce
Shopify shop for Turkish home decor. Ships to every EU country and the UK, payment by Klarna or PayPal.
Every morning the shop’s prices come from the retailer’s POS system. Nobody types anything in.
Result The theme is built from scratch, with room for large product photos. New items only go into the shop once a person has approved them.
In-house product · Restaurants
SnackUp · Restaurant ordering system
Ordering system for restaurants: an ordering page with the menu, plus a device with a receipt printer in the kitchen.
A digital order flow for restaurants, built and run by Zeasy Software. Pictured: the ordering page of Rehana in Duisburg.
Result Over 1,000 orders since launch on August 13, 2025, as of October 7, 2026.
Back then it got stuck on calculating quantity, delivery zone and date. Zeasy Software made it work.
03 / Shopify or your own
If the price is fixed per product, a ready-made shop system is enough. Shopify comes with cart, payment and shipping. We build the theme and connect what’s missing.
If the price only comes out of rules, a ready-made system hits its limit. At Baustoff Express the tonnage decides the truck, the truck decides the free capacity on the delivery day, and the distance decides the price.
| Shopify | Your own shop | |
|---|---|---|
| Price | is fixed per product | comes from quantity, size or distance |
| Delivery | shipping as Shopify provides it | delivery zone and date before anyone pays |
| What we build | theme and connections, for example to the POS system | calculator, order flow and admin area |
| Example | Turkish Home | Baustoff Express |
Turkish Home sells through Shopify. What we added is a program that fetches the item list from the POS system every morning. Changed prices go into the shop on their own.
View Turkish Home ↗If a number in the cart changes at Baustoff Express, the shop recalculates truck, delivery day and price before anyone pays. The shop is custom-coded: the rules live in our own code, not in plugins.
View Baustoff Express ↗For restaurants we already have the ordering system. Guests order on the restaurant’s own domain, and a device in the kitchen prints the ticket.
Ordering system for restaurants ↗If the order comes with customer accounts with roles, approvals or documents, the shop is one part of a larger application. Then we build both together.
Web app development ↗04 / Behind the cart
A shop is tied to the till, the inventory system, invoicing and the delivery plan. We plan these connections before the pages your customers see.
Turkish Home’s POS system has no API, but it exports its items as a file. Our program downloads that file every morning and uses the barcode to find the matching item in the shop. For the same store, our inventory system reads the supplier lists and enters items and prices into the till.
View the inventory system ↗At Baustoff Express the retailer manages products and orders in an admin area of their own. Invoices go out as ZUGFeRD e-invoices.
Before every release, a test program clicks through the order flow in the browser, from the quantity calculator to the checkout. If a step fails, the new version doesn’t go out.
05 / What it costs
We don’t quote a flat price for “a shop”. A Shopify theme and a shop that calculates tonnes and delivery zones are very different amounts of work. We bill by effort. What drives the hours: a theme of your own, a calculator or configurator, delivery zones and dates, the link to the POS or inventory system.
Intro call and cost estimate: €0. You can work out a first range yourself beforehand, in four questions on the contact page. You pay in stages, 25 percent up front per stage.
What it’s about, how big, how demanding, how urgent. No obligation and no contact details. If you send an inquiry afterwards, you don’t type anything twice.
Get a cost estimateEvery payment comes after a sign-off. You can step out between any two milestones.
06 / How it works
If the price depends on rules, we build the calculator first and check it with you against cases from your daily work. We build in one-week sprints, and each ends with a demo.
In the intro call we go through what you sell and what the price depends on: piece, size, quantity or distance. After that it’s clear whether Shopify is enough.
If the price depends on rules, the calculator comes before everything else. You check it with orders you know, like the one that came in by phone last week.
Then come delivery zones, dates, payment and invoicing. Every week you see the current state on the test system.
Before every release the order flow runs through once automatically. After launch, changes of up to one hour of work are included in maintenance.

The intro call costs nothing, and neither does the cost estimate after it. If what you need can be bought off the shelf, we tell you its name and send no invoice.
