TYPO3 Extension Development
Custom extensions for your TYPO3 website
Need a custom feature in TYPO3? I develop professional extensions – from simple plugins to complex backend modules.
Does this sound familiar?
These challenges are part of my daily work
No suitable extension
There is no extension in the TER that meets your requirements – or the available ones are outdated.
Outdated extension
Your extension no longer works after the TYPO3 update. The original developer is unreachable.
No TYPO3 developer
TYPO3 developers are rare. Agencies often have no capacity or lack the required expertise.
Missing integration
You need to connect an external system (CRM, ERP, PIM) to TYPO3, but nobody knows how.
TYPO3 is my speciality
I am Vincent Kilchherr, and I have been developing TYPO3 extensions for over 11 years. From simple plugins to complex backend modules with Extbase/Fluid – I know the system inside out.
My focus is on clean code according to TYPO3 standards. No workarounds, no hacks – just extensions that still work after the next TYPO3 update.

"We needed a complex PIM integration for our TYPO3 website. Vincent developed the extension in record time and documented it perfectly. He is always reachable for questions – I really appreciate that."

Frequently asked questions
Answers to the most important questions about TYPO3 development
The duration depends on complexity. A simple extension can be realised in 1–2 weeks; more complex projects can take 4–8 weeks. After a briefing I can provide an accurate estimate.
Costs vary depending on scope. Simple extensions start from CHF 2,000; more complex solutions with backend modules and APIs from CHF 5,000. After the requirements analysis I will provide a binding quote.
Yes, I support TYPO3 v10, v11, v12 and v13. For older versions I often recommend an upgrade, as support effort increases and security risks exist.
Absolutely. I analyse existing extensions and can extend, optimise or adapt them to new TYPO3 versions. This is often more cost-effective than a new development.
I offer maintenance contracts with guaranteed response times, covering updates for new TYPO3 versions, bug fixes and minor adjustments. Ad-hoc support is also available.
Yes, I regularly support agencies as an external TYPO3 developer. White-label is possible – your client will not notice the collaboration.
