User journeys and product scope
We define user roles, the main purpose and first-version features. Modules and acceptance criteria are documented in the specification.
AV Group · Expert studio
Custom web development
Custom digital products, specialist business logic, customer portals, APIs, integrations, CRM, automation and project architecture. We design the structure, visuals and technical implementation for your business needs.
How we work
Eight stages from discussion to launch
Call and discussion
We discuss your needs, review your preferences and define requirements for the future website.
Initial estimate
We assess the project: scope, technical approach, indicative price and timing.
Contract and 50% deposit
We document the agreed terms in a contract. Work begins after signing and a 50% deposit.
Design preparation and approval
We develop the design, discuss it with you and approve layouts before development.
Website development
We implement the approved design, responsive layout and required functionality.
Forms, analytics and integrations
We connect forms, analytics systems and other agreed integrations.
Final testing
We test pages, responsiveness, forms, analytics, integrations and key user journeys.
Approval and launch
After all approvals, we publish the website and launch the project.
Service scope
What custom development includes
Prototype and interface
We design key screens and states, and agree the user journey, design and responsive behaviour before implementation.
Logic and integrations
We develop agreed business logic, data management and access rules. API connections follow the chosen plan and specification.
Testing and handover
We test critical journeys and error handling, prepare documentation and deployment, and hand over source code and access under the contract.

For business
Custom development for European businesses
An MVP solves the core problem rather than imitating a future large system. AV Group identifies the product core, checks integration constraints and agrees delivery stages. For European projects, we consider user language, data hosting and service availability. Estimates depend on roles, modules, interfaces and load. Listed budgets are starting points; exact commitments follow discovery. We choose technologies around operating conditions, maintainability and your team's development. Additional countries and languages require separate localisation and an agreed budget.
Before work starts
Key questions
How much does custom development cost?
Starting from €4,000 for the scope stated on this page. After the brief, we agree deliverables, timing and a fixed estimate. Additional pages, features and integrations are quoted separately.
What should we prepare before work starts?
Your business description, website goals, service or product list, logo, existing copy, photos and examples. We help identify missing materials.
What does SEO preparation include?
Logical structure, one main H1, section headings, unique Titles and Descriptions, page URLs, image descriptions and internal links. Ongoing promotion, new articles and external links are quoted separately.
Why are prices listed as starting from?
A feature cannot be estimated from its name alone. The budget indicates scale; the specification defines scope.
Who receives the source code?
Access and usage rights are defined in the contract. Third-party libraries retain their licences.
Can you continue an existing codebase?
After a review, we assess risks, further development and any required rework.
