WooCommerce Agency

WooCommerce is the most widely used e-commerce platform in the world because it’s built on WordPress. That’s exactly where its advantage—and its challenge—lie: The store is only as good as the WordPress installation it’s built on. We build both as a single system, not as a plugin on a separate installation.

Store and Website in One System

With WooCommerce, the online store and the website are part of the same installation. Products, categories, blog posts, and landing pages are managed through the same interface, with the same permissions, the same design, and the same search functionality. This saves your team from having to switch systems every day and spares us the hassle of bridging two different systems. You pay no platform fees, no revenue share, and aren’t tied to any provider. Your product data is stored in your database, on your server.

When WooCommerce Is the Right Choice

WooCommerce really shines when you have special requirements: custom pricing logic, product configurators, B2B customer groups, or an inventory management system that needs to be integrated. For a standard product lineup without any special features, a hosted platform is often the faster option. We’ll give you an honest assessment of which approach is best for your project before we get started. We’ll make this decision together during our initial consultation.

A WooCommerce store is more than just the plugin. Your product selection, checkout process, payment options, shipping, and integration with your systems all need to work together seamlessly. Here are the areas we handle.

Store Design

We develop a custom theme instead of modifying a multipurpose theme. The product overview, product detail page, shopping cart, and checkout are designed individually—not just given a new color scheme. Variants, image galleries, and availability options are given the space your product lineup needs.

Checkout Optimization

WooCommerce's standard checkout asks for more information than most stores need. We streamline the fields, disable unnecessary required fields, and add express payment methods. Where it makes sense, we use the new checkout blocks; where it doesn't, we stick with the classic template.

Payment and Shipping

We set up PayPal, credit card, Klarna, SEPA direct debit, and purchase on account using the payment providers’ plugins, not aggregate extensions. We configure shipping zones, weight and price tiers, and integration with DHL or another service provider to suit your logistics needs.

Product Management

Simple products, variable products with attributes, bundles, or digital downloads: We set up the product types so your team can manage them efficiently. For large product catalogs, we also offer CSV import, bulk editing, and automatic synchronization with your inventory management system.

Interfaces

Orders go into the ERP, inventory goes back to the store, customers go into the CRM, and invoices go into accounting. We use the WooCommerce REST API and webhooks, and build our own middleware where a system doesn’t provide a usable interface. Every connection is documented and monitored.

Store Performance

Online stores are dynamic, so simple page caching has only limited effectiveness. We use object caching, well-organized database tables, HPOS for order management, and hosting designed specifically for WooCommerce. This has a positive impact on both bounce rates and search engine rankings.

These companies know how we work

A WooCommerce store isn’t installed—it’s set up. Product types, tax rates and tax classes, shipping zones, payment providers, order statuses, and the automated emails sent to your customers are configured for your store instead of remaining at their default values. Otherwise, errors—especially regarding taxes and shipping—can occur that aren’t noticed until the store is up and running and then affect every order. We set up order management on HPOS from the very beginning so that the store remains fast even as order volume grows, and we create a staging environment where we test changes before they go live. The setup also includes a handover: We’ll show your team how to create products, process orders, and issue refunds. After that, you’ll be able to handle day-to-day operations on your own and only call us for anything beyond that. As a WooCommerce agency, we dedicate most of our time to this setup.

„To me, having a strong partner is important. Someone who is “passionate” about their work, who offers well-reasoned professional objections but also accepts and continues to fully support my decisions as a client when I choose a different path. I’ve been working very successfully with seitenweise in this way for many years—both in day-to-day operations and on many large-scale projects.“

ONLINE STORE

We build online stores that drive sales and are easy to maintain.

seitenweise is a digital agency based in Bielefeld, founded in 1999. Through more than 500 projects, we’ve learned that an online store rarely fails because of technical issues, but rather because no one can effectively manage it after launch. That’s why we plan WooCommerce projects with operations in mind: Who maintains which data, which processes run automatically, and what happens during the next major update? Design, development, and support all come from the same team at our agency.
