Practice 03 · 13 servicesWeb, software & digital solutions
A showcase website, a piece of business software and a mobile app serve different audiences under different constraints, yet share one requirement: to still be useful years after launch. Kopus’s web, software and digital solutions practice designs, builds and maintains these tools, choosing the technology only once the use is understood.
What is at stakeWhat is at stake in a digital project: usefulness, integration, lifespan
Digital projects seldom fail for technical reasons. They fail because the tool does not match how work is really done, cannot talk to the systems already in place, or has nobody to keep it alive. Four questions come before any line of code:
- Who will use the tool, in what setting, for which tasks?
- What data already exists, and in which systems (ERP, CRM, accounting)?
- Would an off-the-shelf product do the job? If so, we say so.
- Who will host, update and extend the tool after delivery?
13 services to move forwardOur web and software services
Website design and development
Structure, content, design, performance and technical SEO are handled as one piece of work. Every website is custom-built, with a back office designed for your updates.
Discover 03.02Business showcase website
For an SME, a professional practice or a trade business, the website has to reassure and prompt a contact. Proof points, key information and calls to action are arranged around your visitors’ questions, local search included.
Discover 03.03Ecommerce website development
An online store loses sales at every poorly designed step. Catalogue, search, product pages, checkout, shipping, order handling and compliance are built together, with conversions tracked from day one.
Discover 03.04Web application development
User accounts, dashboards, customer portals: we define roles, data and integrations before building an application that runs in any browser.
Discover 03.05Custom software development
When a packaged product forces costly compromises, we build software that follows your own business rules, delivered in testable releases, with code that belongs to you.
Discover 03.06Custom business software
Quotes, scheduling, case tracking, production: we replace shared spreadsheets and double entry with a tool centred on one specific process, designed with the people on the ground.
Discover 03.07Desktop application development
Hardware access, offline work, heavy computation: some uses call for an application installed on the workstation. We assess the target environments (Windows, macOS) and the deployment constraints.
Discover 03.08Mobile app development
Moments of use, core functions, offline needs, notifications: we pin these down before choosing between native and cross-platform, then handle publication on the app stores.
Discover 03.09SaaS platform development
Selling a tool by subscription means multi-tenancy, billing, onboarding, security and scaling. We scope these operational matters as carefully as the features.
Discover 03.10UX and UI design
A pleasant interface can still slow its users down. We start from the tasks to be completed, prototype the journeys and validate the choices with real users.
Discover 03.11API integration
Copying information from one tool to another wastes time and breeds errors. We map the data, flows, rules and checkpoints between your systems.
Discover 03.12Application maintenance
A tool nobody looks after becomes fragile. We assess risks, resolve incidents, schedule security updates and prioritise improvements, even on applications built elsewhere.
Discover 03.13Email deliverability and transactional sending
A quote, an invoice or a licence key that lands in spam is a customer left waiting. We authenticate your domains (SPF, DKIM, DMARC), centralise the sending of your websites and software on a monitored relay, and flag any spoofing of your name.
DiscoverWhat makes the differenceWhat bringing the practices together changes for your web and software projects
In this practice, having consulting expertise on hand matters as much as code quality: before we equip a process with software, we check that the process is stable, rather than automating a mess.
The reverse holds too. A website built here applies the identity defined by the branding practice without reinterpretation, and a web application can carry document processing designed by the AI practice from its first version. You never have to referee between suppliers passing a problem back and forth.
Your questionsFrequently asked questions
Ask a questionDo you build on a CMS or from scratch?
Custom-built, always. Our websites and shops are developed for their purpose, with no theme or plug-ins: they are faster, more secure, better ranked, and their back office is designed for the people who update them. The code belongs to you.
Who owns the code at the end of the project?
You do. Source code, access credentials and documentation are handed over, and maintenance can go to whoever you choose.
Can you take over an application developed by another provider?
Yes, after a technical audit of the code, dependencies and risks that establishes whether a takeover is reasonable.
