The original developer or agency is no longer available
Knowledge and documentation are incomplete, with nobody clearly responsible for the system.
Existing PHP systems. Clear technical responsibility.
When the original developer is no longer available, maintenance has become reactive or the system is too important to replace, we step in and take technical responsibility.
When an existing system becomes a risk
Knowledge and documentation are incomplete, with nobody clearly responsible for the system.
Updates are postponed, incidents consume attention and upgrade blockers remain unclear.
Booking, payment, customer and integration workflows must continue during the technical transition.
The first task is to identify fragile components, critical integrations and missing knowledge, then establish a realistic scope and budget.
Core services
A paid review of the codebase, hosting, integrations and immediate concerns. Scope and price are agreed before detailed investigation begins.
Request Technical AssessmentPlanned maintenance, security updates, incident investigation and reliable delivery of changes while essential system knowledge is preserved.
Discuss ongoing supportUpgrades, refactoring and staged migrations that improve unsupported components without disrupting established business workflows.
Tell us about your systemTechnical System Assessment
Taking responsibility for an existing system should begin with evidence, not assumptions. The Technical System Assessment creates a clear view of the current system, its immediate risks and the practical options for stabilisation, maintenance and modernisation.
Depending on system size, access and complexity. Scope and a fixed assessment price are agreed in advance.
Typical service pathway
Most long-term support relationships begin with three practical phases.
A structured review of the current system, risks and practical next steps.
Resolve immediate issues, restore control and create a reliable technical baseline.
Long-term maintenance, reserved capacity, monitoring, advice and incident response.
Why Costa Web Experts
Costa Web Experts is led by Roel, a senior PHP and TYPO3 specialist. The same senior specialist remains involved from assessment through delivery.
Access, decisions and system knowledge are documented so the client remains in control. Business continuity comes before an unnecessary rewrite.
Systems & Technologies
Our experience covers custom PHP, TYPO3, WordPress, Drupal and heavily customised business applications where standard CMS maintenance is not enough.
We work with custom modules, integrations, payments, bookings, portals and dashboards, and identify accumulated business logic before recommending upgrades, replacement or migration.
Case studies
01
We maintain and extend a business-critical PHP and TYPO3 platform used by multiple organisations to process financial transactions, generate documents and manage operational workflows.
02
We maintain and develop a custom PHP platform that manages reservations, contracts, payments, credits, transport planning and customer communication.
03
We migrated a heavily customised TYPO3 application to a supported platform while preserving existing records, workflows and business-specific functionality.
Ongoing Support
A named senior specialist and reserved capacity provide continuity beyond isolated development hours.
Reserved senior capacity, planned maintenance, incident investigation, documentation and coordinated releases.
From approximately €1,250 per month
Scheduled maintenance, advice and named senior responsibility.
From approximately €2,500 per month
Reserved capacity, regular improvements and faster incident response.
Typically €4,000–€7,500 per month
For high operational importance, frequent change, monitoring or agreed escalation.
These are indicative service levels, not universal packages. Scope, capacity and response arrangements are agreed after the assessment or intake.
Discuss ongoing supportManaged hosting
Hosting can be part of ongoing support, with one party coordinating the application, PHP environment, database and platform updates.
This shortens the route from monitoring alert to investigation and keeps deployments coordinated.
Organisations we have worked with
Experience across businesses, agencies and public-sector organisations.
Technical intake
A useful first conversation covers what the system does, its importance to daily operations, who maintains it and what triggered the need for a technical transition. Perfect documentation is not required.
