Our Services at CartCraft

At CartCraft, we provide expert digital solutions tailored to meet your business needs.

UI/UX Design

We design in Figma and have done so for years, across a long list of projects. Desktop, tablet and mobile, click dummies and user flows where they help, and what we draw we also build.

Designed and built by usGartenFitPsychiatrie GrabbeMaison Mollerus

Designed for every width

Websites, online shops, web applications and mobile apps, drawn in Figma for desktop, tablet and phone before anything is built.

Click dummies and user flows

On request the design comes with a clickable prototype and the flows behind it, which is where the open questions about a screen get settled before development starts.

Built by us, animations included

The design does not get handed over and left. We build it ourselves, with the animations, hover states and the small reactions that make a finished page feel the way the design looked.

WordPress Website Development

From the first draft to the launch we build with Elementor, and where the standard set stops we write the module, the plugin or the theme ourselves. Server configuration, load time and upkeep after launch belong to the same job.

Design built one to one

We take the design and build it in Elementor down to the spacing, and we put in the texts and the images, so the pages arrive finished rather than as empty templates.

Elementor modules of our own

Where a standard widget cannot do it we write the module. A slider with your rules, a filter over your own data, a section that behaves the way the design says it should.

Plugins and themes we write

A feature with no plugin behind it gets one, and the same goes for a theme. Both stay in your installation and both are documented, so a later change does not depend on us.

Integrations, exports and mail workflows

Data goes where it is needed. Interfaces to the systems you already run, exports of the lists somebody keeps building by hand, and mails that go out on an event instead of on a reminder.

Speed, on both levels

Loading time is worked on in the site and on the machine behind it. What the browser downloads and when, and caching, PHP and web server settings on the server itself.

Hosting, domains and upkeep

Hosting on servers in Germany, the domain and its certificate, the updates afterwards and the security settings that belong with them, from the server itself to the mail records that keep your mail trusted.

Custom Shopify Apps Development

Apps that add what your store is missing, from new steps in the checkout to data that has to move between Shopify and the systems you already run.

Bespoke Solutions

We build what no public app covers, and we build it around the way your store already works, not around a template.

Complete Development Cycle

From the first sketch to the finished app, including hosting, integrations and the release into your store.

Comprehensive Documentation

Every app we hand over comes with a written guide, so your team can run it without calling us first.

Public Shopify Apps

We publish apps for the gaps in the Shopify App Store: the jobs that no listed app does, or that none does well enough to trust in a live store.

An app earns its place when it does one job properly, so we keep the interface close to the Shopify admin your team already knows. Our own listing is the Omnibus Price Tracker. It records the lowest price of the last 30 days for every product and shows it where European price law asks for it.

Omnibus Price TrackerView it in the Shopify App Store

Custom Shopify Apps

Custom apps are for the jobs only your store has. Most of them move data: they enrich what Shopify holds about a product or an order and carry it to the systems around it.

We like Cloudflare Workers for the delivery. They are small, they cost close to nothing to run, and they stay up around the clock. GastroHero runs several of them: an order lookup that lets a guest find an order without a customer account, Checkout UI Extensions that add steps inside the checkout, and a warranty add-on that a Shopify Function prices into the cart.

Shopify Theme Development

We work inside the theme of a running shop. Tracking that measures what it should, features your team can set without us, and speed work on the pages that carry the revenue.

Shops we work onGastroHeroMamarellaPuroMenusmaints

Tracking that adds up

Server side tagging, consent mode and the diagnosis when orders stop being counted. We follow the click from the ad to the order and name the point where the number gets lost.

Load time where it pays

The pages that carry the revenue come first. What the browser has to download, when it downloads it, and which app scripts are allowed to hold up the first view.

Features with their own settings

Every custom section arrives with its settings in the theme editor, so your team changes texts, images and rules without us. Documentation with screenshots comes with it.

Animations and the design polish

Hover states, transitions and the small movements that make a shop feel current, built into the theme instead of bought as another app.

Connected to GitHub, every change versioned

The theme lives in a repository. Work goes through a branch and a preview theme, releases stay traceable, and a change that turned out wrong is one step away from being undone.

Functions, checkout extensions and custom apps

Where the theme reaches its limit we add Shopify Functions, checkout extensions and a custom app, developed, deployed and looked after as one package.

IT Security Services

We work on two levels, the application and the server it runs on. We scan what is reachable from outside, harden what the scan found, and set the mail records that decide whether your mail is trusted.

Security mandatesMelittaOldenburgische Landesbank

External scans

We scan your websites, shops and servers the way an outsider sees them, without access rights and without exploiting anything we find. What comes out is a list sorted by risk.

Assessments that go deeper

With credentials, and only with your written go ahead, we look at the parts a visitor never reaches, from roles and rights to the admin area and the interfaces behind the front end.

Hardening the application

Updates and a routine that keeps them coming, access cut back to what a role actually needs, two factor login, and the settings that close what the scan found.

Server scans and configuration

The machine behind the site. Open ports and services, patch level, web server, PHP and database settings, and backups that have been restored at least once.

Email security with SPF, DKIM and DMARC

Three records decide whether your mail arrives and whether somebody else can send in your name. We set them, read the reports that come back and move the domain to a policy that turns forgeries away.

Reports and the work after them

Every finding is written down with what it allows and how it is closed, in a document you can hand to a customer who asks for it. We then carry out the measures, or hand the list to your own team.

Where our scope ends.Certification audits are not ours to run. For ISO 27001 we deliver the gap analysis, the technical measures and the documentation, and the certificate itself is issued by an accredited body. We also do not administer third party environments such as Microsoft 365, we do not run staff training, and we do not operate a security operations centre.

Process Tools and Internal Portals

Software for the steps that still run on paper, in spreadsheets and in the heads of experienced staff. Built around the workflow you already have, hosted in Germany or wherever your rules require, and billed by the hours worked.

Case studyWarehouse portal, from paper to portal

Built around your workflow

We map the steps, their order and the rules that have to hold, and the tool is built around that. Nobody has to change the way the work is done to fit a piece of software.

Portals for the floor, dashboards for the office

A warehouse portal for a pharmaceutical client, name confidential under NDA, runs from goods receipt to the parcel label. A management dashboard puts the decisions of a working day on one screen.

Documented the way an audit expects it

Every step is recorded where the work happens, on a phone or a tablet, so the documentation an ISO 9001 audit asks for falls out of daily use instead of being written afterwards.

Our Project Approach at CartCraft

At CartCraft, our project process begins by consulting with the client to determine the best technical solutions and strategies for implementation.

We leverage our experience and past client projects to develop a solution concept that addresses the client's needs with practical functionalities and suitable technologies.

Planning and Design

Based on this consultation, we draft a preliminary timeline and budget to manage expectations, outlining key milestones to ensure a structured project flow. Often, this phase includes creating a UI-UX design to guarantee design quality and enhance user experience, providing a visual blueprint for developers and setting clear expectations for the client.

Development and Implementation

The project execution typically proceeds with minimal client involvement. We usually establish a CI-CD pipeline with a GitHub repository early on to streamline the development process. Our team employs agile management techniques to track progress and systematically address all milestones and functionalities.

Quality Assurance and Client Review

The development process focuses on balancing performance, functionality, and usability. After coding, each app undergoes rigorous quality assurance and security testing, including penetration tests, to ensure data security and app integrity.

Project Completion

Upon project completion, depending on its nature, we either move to subsequent phases, conclude the project, or establish maintenance agreements.

Identifying Needs

At CartCraft, we develop apps like the Ingredient Nutrition Manager and Discount & Price Tracker to meet regulatory needs unsupported by Shopify, addressing community demands for more customizable and efficient solutions. Conversely, our SmileScore App, born from innovation, ventures into the market with uncertain acceptance.

Planning and Design

We thoroughly plan app functionalities based on anticipated customer inquiries and previous project experience, followed by crafting user-friendly UI/UX designs that ensure an excellent user experience from the start.

Development and Testing

The development process focuses on balancing performance, functionality, and usability. After coding, each app undergoes rigorous quality assurance and security testing, including penetration tests, to ensure data security and app integrity.

Verification and Launch

Post-development, apps are verified with Shopify and upon approval, released. We monitor initial user feedback to swiftly address any bugs and gather insights for future enhancements.

Continuous Improvement

We engage early testers from our customer base, offering them free access in exchange for valuable insights. This helps us refine our apps before wider release. We continuously update our apps to adapt to new Shopify` APIs and requirements, ensuring best practices.

Privacy and Data Security

We minimize customer data storage on our servers, leveraging Shopify’s metafields for secure data handling. This reduces IT risks and enhances app performance and flexibility.`

Flexibility and Customization

Our apps are designed to function effectively with minimal setup yet offer extensive customization options for those who prefer to tailor every aspect.
