TYPO3 Development

TYPO3 development and upgrades for European agencies

Support for TYPO3 website builds, LTS version upgrades, custom extensions and ongoing maintenance. Work with us on a project, ongoing support or dedicated developer capacity. Your agency leads the client relationship; we contribute the agreed technical work behind your brand.

TYPO3 Work We Deliver

TYPO3 projects often involve more than building pages. They require careful work around extensions, legacy code, integrations, content structures, performance, security, and long-term maintainability.

TYPO3 Development

Build custom TYPO3 websites and features that match your client’s content, workflow, and technical requirements.

TYPO3 Upgrades and Migration

Review and upgrade existing TYPO3 installations, including extension compatibility checks, custom-code changes, staging, testing and release planning. Content migrations are scoped around the source data and target structure.

Custom TYPO3 Extensions

Create, improve, or repair extensions for client-specific workflows, integrations, content elements, and backend functionality.

TYPO3 Maintenance and Support

Maintain existing TYPO3 websites through agreed updates, bug fixes, performance investigation and planned improvements. Support scope, priorities and availability are confirmed for each platform.

TYPO3 Integrations

Connect TYPO3 with APIs, CRMs, ERP systems, marketing platforms, payment systems, and other business tools.

Multi-language and Multi-site TYPO3

Build and maintain TYPO3 platforms for organisations with multiple languages, regions, brands, or websites.

Complex TYPO3 upgrades need a careful delivery path

Older TYPO3 installations can contain unsupported extensions, undocumented custom code, legacy integrations, and hosting constraints. We assess the platform before promising a path, then work through the upgrade in a controlled staging environment.

TYPO3 6.2 → 12.4.x

“It was a very good experience to work with HFZ Tech. They upgraded our Typo3 website which includes many extensions, also undocumented custom extensions from 6.2 to 12.4.x in a professional way and the site didn't have to be frozen for much time. HFZ Tech found solutions for all unexpected issues very fast in all cases and always gave clear advice about actions that we had to take.”
