Your customers are online— let’s reach them.
Wherever you are in French-speaking Switzerland, we can work with you on site or remotely to design a website tailored to your business and objectives.
Our process
Every project begins with an interactive prototype and a detailed proposal. Once we have incorporated your feedback and received your approval, we build the solution with transparent milestone and time tracking, then handle testing, launch or delivery. Explore our case studies.
After you contact us through one of our forms, we define your project before you make any commitment.
Once the agreement is signed, we work with you from prototype to development.
We quality-check and deliver your project, after which you receive your SOLIS client card.
What you receive
Our agency defines your objectives, content and users before designing the prototype, structure and visual experience. We then build a fast, accessible and manageable website and support you through launch. Explore these choices in more detail in the How we add value section further down this page.
From3’500 CHF
We clarify your objectives, users, content and priorities, then create an initial clickable prototype to validate the project direction.
We organise the pages, navigation and content around your visitors’ needs and the searches that matter to your business.
We design a responsive interface that reflects your identity, remains clear on every screen and guides visitors towards the actions that matter.
We build the website to measure and configure a tailored administration interface so your team can manage the relevant content independently.
We build in performance, accessibility, technical SEO and the necessary safeguards from the outset to create a reliable, lasting foundation.
We test the screens, forms and tracking, configure the hosting and domain, then hand over access and the technical materials.
After launch, we can provide maintenance, support, content improvements and the development of new features.
La Gouttière wanted to bring its menu, products, photographs and news together in one tool while bringing the bar’s unique character online. We shaped the technology, administration and design around its real needs.
We recommended a Next.js foundation connected to a custom CMS limited to the features the team genuinely needs.
Rather than adapt a template, we designed every screen around the identity La Gouttière wanted to convey.
How we add value
We do more than develop your website: we clarify your objectives, define the essential features (MVP) and organise the phases, budget and schedule to maximise its chances of success.
A custom solution requires a higher initial investment, but reduces subscriptions, licences and maintenance costs over time. Every feature meets a real need, so the solution remains under your control, scalable and free from the limits of a template.

Frequently asked questions
Custom development, CMS, SEO and content: what you need to know before launching your website.
SOLIS brings design, development and SEO expertise together in one team to create fully custom solutions—never template-based. From our base in Martigny, we draw on more than 10 years of experience and over 100 completed websites and applications. You receive an initial interactive prototype with your proposal, then track each stage and the hours spent on your project through your client area.
We begin by defining your objectives, content and user journeys, then prepare an initial interactive prototype together with a detailed proposal. Once the agreement is signed and the deposit paid, the prototype enters an iterative phase: we refine it with you until you are completely satisfied. Development starts only after your full approval, so the intended outcome is clear before any code is written. Testing, launch or delivery follows, with a client area where you can view milestones, progress and the hours spent on the project.
The prototype supplied with the proposal is an initial clickable version of your future solution. It gives you a tangible view of the design, structure, user journeys and key content, while helping us estimate the scope, hours and budget accurately. It is free and carries no obligation. If you accept the proposal, it becomes our working foundation: after the deposit, we refine it as much as needed until you give full approval, and only then do we begin development.
Prices start at CHF 3,500 for a website, CHF 7,500 for an e-commerce site, CHF 9,500 for a mobile application and CHF 10,000 for business software. The final amount depends on the features, content, automations and integrations that genuinely add value. Because the proposal is prepared alongside an initial interactive prototype, we can estimate the scope and hours based on something tangible rather than an abstract idea.
A 50% deposit confirms the project and starts the feedback and prototype-finalisation phase. We refine it until you are entirely satisfied; development begins only after you approve the design and user journeys. The final invoice is then adjusted to reflect the work actually completed: unused hours are deducted, and any additional hours are discussed and approved with you before they are incurred.

A template is designed to meet generic needs. As soon as your identity, content or user journeys fall outside that framework, workarounds, plugins and scripts multiply, adding weight to the site, its maintenance and its subscriptions. A custom website starts with your business instead: every page, call to action and feature is designed to build trust, guide visitors and support conversion. The site loads only useful code, the CMS reflects how your team really works, and future development remains under control without relying on third-party theme updates that may break or overwrite your customisations. The initial investment may be higher, but the solution remains faster, more predictable and more cost-effective over time.
| Criterion | Custom SOLIS solution | Standard template |
|---|---|---|
| Identity and design | The interface starts with your brand, content and objectives. | The project has to fit a pre-designed structure and set of components. |
| Performance | The site loads only the components and dependencies it actually needs. | The result depends on the quality of the theme and may include unused options or scripts. |
| Content management | The CMS provides the fields and actions suited to your team’s work. | The administration interface follows the generic model of the theme and its extensions. |
| Maintenance | The project’s code and dependencies remain under control. | Customisations may depend on theme and plugin updates. |
| Scalability | New features fit into an architecture designed for the project. | Changes remain straightforward as long as they fit the template’s capabilities. |
| Recurring costs | Recurring costs are concentrated on the hosting and services you have actually chosen. | Theme, page-builder and plugin licences can add up. |
| Ideal use case | An organisation with a strong identity, specific user journeys or a product designed to evolve. | A simple project that needs to launch quickly, with limited differentiation and requirements that closely match the chosen template. |
SOLIS creates marketing websites, corporate sites, editorial platforms, client areas and more advanced web platforms. A project can also combine the public website with business software or an online management tool: project tracking, client requests, documents, resources, dashboards, automations or connections to your existing systems. The structure, pages, calls to action and management interfaces are defined around your organisation rather than a template or predetermined number of pages. You gain a coherent solution that can evolve from a company website into practical day-to-day tools without accumulating paid extensions.
Yes. The CMS is built around the content your team genuinely needs to manage, with only the fields and actions they need. Once the prototype has been approved, SOLIS develops it as agreed and integrates the copy and images supplied for that version. If the content changes during development, you will be able to update it yourself in the CMS after delivery.
Yes. The technical foundations cover semantic structure, metadata, indexing, the mobile experience and performance. Because the site loads only the code and dependencies it needs, we also retain greater control over speed and stability. SEO nevertheless depends on content, competition, site authority and time. An acquisition-focused content strategy can then be developed with our SEO partner Lyndon Vouilloz to set realistic objectives, define target audiences, prioritise topics and establish performance indicators. The aim is to build lasting visibility and qualified traffic without making unrealistic promises about a specific Google ranking.
A template is a pre-designed visual and functional model, such as a WordPress or Shopify theme. It speeds up a standard project, but imposes a structure, components and often a predetermined set of dependencies. A custom solution instead begins with your objectives, identity and your team’s real working practices. SOLIS develops both the visitor-facing experience and the admin area used by your team. A content management system (CMS) is therefore not a third way to design a site; it is the tool that lets you manage its copy, images, pages or products without touching the code. In a SOLIS solution, the CMS is created or configured specifically to show only the fields and actions you actually need. For an online shop, Shopify can serve as the CMS while the theme, user journeys and visible features are custom-developed.
