FAQs
What services does W4 actually offer as a digital agency?
We cover the disciplines that matter for a digital transformation: e-commerce development, digital strategy and consulting, PIM integration with elytra, UX/UI design, gamification, and CommunityNet for Swiss municipalities. You get one point of contact, one team, and one aligned process instead of stitching together several specialist agencies.
How much does a digital project with W4 cost?
The investment depends on scope, the system you choose, and the complexity of the integrations involved. One-off projects such as a new shop or a strategy sprint are billed as a fixed fee, ongoing care and further development as a retainer. In an initial call we clarify your needs and put together a quote that fits.
Which platforms and systems do you work with?
We work with established platforms like TYPO3, Drupal, Sanity and HubSpot for content, Magento and Shopify for e-commerce, plus elytra, Odoo and HubSpot for PIM, ERP and marketing automation. If you use a system that is not on our list, we can integrate it as long as it offers an API or another data interface.
Which of your services is the right fit for our case?
It depends on where you are today. If you want to start selling online, e-commerce development is the entry point. If your product data is scattered across systems, a PIM integration with elytra makes sense. For larger initiatives or when the target picture is still unclear, we start with strategy consulting and put the right service mix together for you.
How does the collaboration work, and which tools do you use?
We work in clearly defined phases, structured around milestones with working interim builds. After each milestone you see what has been delivered, instead of waiting for the finished project. We use Figma for design, Jira and Confluence for tickets and documentation, Google Workspace for collaboration, and GitHub or GitLab for code management. You are involved at every stage, see progress transparently and can adjust priorities at any time.
What sets W4 apart from other digital agencies?
Three things. We have been at it since 1994 and have delivered everything from classic websites to complex platforms, B2B shops and enterprise integrations. We bring strategy, design and development together in one team rather than separate silos. And we build solutions that fit your processes instead of forcing you into a standard product.
