TET PDF IFilter is free for non-commercial use on desktop operating systems (but not server operating systems).
We offer optional support contracts in combination with a new product license, or to renew an existing support contract. An active support contract includes technical support with short response times, all minor (maintenance) and major (functional) updates and other advantages (see support description).
The support fee is 20% of the license fee per year.
A major update changes an older license to a license for a newer version on the same platform. Licenses for TET PDF IFilter 4 can be updated to TET PDF IFilter 5 at a reduced license fee. Customers without a support contract can add support with a major update. In this case the support fee is based on the full license fee of the product (not the update fee).
