Frequently asked questions
Everything you need to know.
Scoping answers on cost, technology, schedule and responsibilities.
How much does a custom website like pebify.be cost in Brussels?
Kanexio’s indicative prices start at €15,000 excluding VAT for a defined functional scope, range from €30,000 to €50,000 excluding VAT for an application with more journeys or integrations, and start at €50,000 excluding VAT for a broader platform. These amounts are indicative. The quotation confirms roles, data, features, integrations, third-party services and applicable conditions.
How does this differ from a business website?
A business website organises content and contact actions. A custom project adds specific roles, rules, data, integrations or processing. A booking or calculation does not automatically make a platform complex: scoping determines an appropriate architecture.
Can you integrate a booking system connected to Google Calendar?
A Google Calendar connection via OAuth can be included in the scope. Source calendars, availability rules, permitted writes, messages, .ics files, concurrency cases and responsibilities must be defined and tested. Two-way synchronisation is not assumed: it depends on the accepted rules and access.
How long does it take to deliver a custom project?
The timeline depends on the functional scope, third-party service access, content, migrations, tests and pace of approvals. The proposal sets milestones, responsibilities and the intended launch date. Only the accepted schedule is binding on the parties.
Will I really own the code and data?
The quotation and contract distinguish client content and data, accounts, the domain name, hosting, licences, third-party components and code produced for the assignment. They specify rights, export formats, handover conditions, the timing of transfer and any reuse limitations.
Can you take over or redesign an existing website?
A takeover can include an inventory of content, URLs, data, accounts, integrations and dependencies. Redirects, migrations and tests are priced from that inventory. A migration does not guarantee preserved SEO rankings or freedom from regressions; checks and responsibilities are documented.
